Cultural relativism Essay

The issue of universalism of human rights vs. cultural relativism has been a focal point of heated debate for the last several decades. As globalization is bringing nations together, cultural differences and peculiarities become increasingly more salient. The Universal Declaration of Human Rights, adopted by the United Nation in 1948, lists several categories of rights that the peoples of the world have agreed to accept and recognize. These rights include the right to life, liberty and security of person; the right to be free from slavery and servitude; the right not to be subjected to torture or to cruel, inhuman or degrading treatment or arbitrary arrest, detention or exile; the right to marriage with the free and full consent of the parties; the right to own property; the right to freedom of thought, conscience and religionm; and the right to work, to free choice of employment, to just and favorable conditions of work (United Nations, 1948). These rights are universally recognized because they protect the dignity of an individual and the basic social institutions which are present in virtually every culture. However, their universality is still contested, as â€Å"human rights as laid out in the international covenants ignore the traditions, the religions, and the socio-cultural patterns of what used to be called the Third World† (Tharoor, 1998, para. 1). For example, in some African societies, â€Å"group rights have always taken precedence over individual rights, and political decisions have been made through group consensus, not through individual assertions of rights† (Tharoor, 1998, para. 4). There are many instances when traditional practices conflict with universal human rights. For example, female genital mutilation, practiced by some African and Asian people for cultural and communal reasons, translates into irreversible lifelong health risks for females (UNICEF, 2008). The debate whether human rights are universal is perennial. It is important to recognize, however, that an effective framework for the protection of human rights can be developed only using a bottom-up approach, giving the broad support of a society where human rights are promoted.

Teenagers Woking and Studying in the Same Time

In some countries, teenagers have jobs while they are still students for different reasons. They work either need money to help their parents or to get experience. Some people think that have job and study in same time is not a good idea, because can damage their grade. But, I think that this is a good idea. I believe that the money them earn is necessary to some teenager. In addition, the young people might learn some things in the practice before start the University. In my opinion, the teenagers become more responsible. In my country, Brazil, is very common teenagers work during the day and study at night. This young people generally need the money, because their families are very poor and can't afford all expenses. In this case, the student need work, otherwise they don't have possibility of study. Thus, is a good idea work, because working the student will be able to study, and in the future they will have a better job. Other reason is that they get experience earlier. The teenagers learn the things in practice before start the University. This may help them get better jobs in the future. I have some friends that during the high school have worked. As they start the course in the Universities, they already had a good job. Finally, in my view teenager have a job while they are students yet become them more responsible. I would like explain why. When the young work and study in the same time, they learn to manager their schedule to be able do all the things. As a result, they pass less time playing video game or in the internet. To sum up, although some people think that the teenager students should just study, I believe that is a great idea work while they are in the school.

Comparison of Modern Women and of Ancient Greece

Greece were a little more than virtual slaves, themselves. From the day of their birth, up to their deaths, females were constantly controlled by a master, normally the father than overtaken by her husband. Girls approximately the age of 1 5 were chosen an appropriate suitor by their fathers, usually a man already more than twice her age (p. 75). Most men spent little time at home; therefore, the wives dominated home life through her skills of sewing, cooking, spinning, weaving, and preserving the slaves of the family household.On average there were plenty of slaves to help with the dally chores, only the most destitute homes was the lady responsible for these duties alone. Therefore, wives In some aspect were more privileged than women in our present society, where the domestic labor Is generally completed single-handedly. Women had specific boundaries in society and the events that took place there. Women didn't have the privilege of voting, and were allowed no entitlement into pub lic office. Although women were forbidden in political positions, they were Greek citizens and could not be violated or sold into slavery (p. 4). They were prohibited from watching the Olympic Games as they contained fragments of nudity, and were only permitted to participate in chariot racing. (Graham) Public roles that women were encouraged to take role in were funerals, weddings, and religious celebrations where they could socialize outside of the home. â€Å"A wife's main duty, apart from managing the household, was to provide a male heir n order to maintain the family's hold over its property,† The Western Experience.Since men dictated all property in classical Greece, it was a necessity to produce boys in addition to girls. It is difficult to depict the ancient feminine lives of the Greeks exactly, as we have no recorded verification documented directly by them. A number of Greek gods and written Greek epics portray women as leaders, and are sharply admired by men. Sour ces.

Week 8 705 - Assignment Example This requires knowledge on budgeting and components of budgets so that a DNP can collaborate with line personnel and inform them to ensure availability of resources for meeting patients’ needs. Ordering of tests and prescription of medicines originates from DNPs and the professionals are the right source of information for budgeting for the necessary resources. DNPs’ knowledge on budgeting can facilitate accuracy in resource allocation and availability of the required resources. In addition, ability to identify each of the direct costs such as personnel, equipments, supplies, and training expenses and to allocate expected costs to them facilitates budgeting within a DNP’s department and informs a facility’s budgeting (Loyns & Gitlin, 2008). Personnel are critical to service delivery and understanding workload volume informs DNPs on the required human resource base. The most common volume and peak volume are important to estimating extreme ends of a facility’s needs that can ensure economic, but sufficient, allocation of resources. Reliance on most common workload, together with further analysis then informs DNPs roles in budgeting for their departments and their facilities. As a leader, a DNP needs to understand human resource planning concepts for informing human resource management on appropriate human resource composition and for ensuring optimal personnel output in a DNP’s department through motivational factors (Waxman, 2012; Loyns & Gitlin,

Philosophy of Time Essay Example | Topics and Well Written Essays - 750 words

Philosophy of Time - Essay Example On the other hand, Isaac Newton defined a number of significant ideas including that of time. Even though he understood that clocks were imperfect and measuring time was subjected to human fault, he believed that absolute time was comparable to a worldwide, supreme God-like time, one similar to everyone, in all places; people would experience time in a similar manner no matter the place. Since chronological time is solely somewhat adequate in an experiential sense and totally inadequate to clutch the meaning of aging, there is need to combine both a broader cultural and a personal sense to revive other temporal perspectives. The aim of both perspectives, symbolized in the main positions of Augustine, Aristotle, the existential philosopher Heidegger, and phenomenologist Husserl, has been to make up time as such from their views. There are benefits that an individual might derive from philosophy of time. First there is a clear relationship between the human mind and time. St Augustine adopted a subjective opinion of time stating, "It is in you, O my mind, that I measure time,† (St. Augustine) meaning that human mind actually structures a person’s perception so that he can know the fact that time is likened to a mathematical line. In this theory therefore, I believe that time is a form of conscious knowledge, and people’s sense of it is a vital condition of their sensation or experience. Philosophy of time is important in planning for the past, the present, and the future. C.S. Lewis argues that our life changes with time. He articulated that "The duration of consciousness is not the same as the consciousness of duration." (C.S. Lewis). One moment disappears when another moment sets in and this is what gives room for noticeable developments in one’s life. This arrangement is not the only way that life is experienced by each one of us, but also the way by which all things happen or exist. We tend to assume that everything happens just the way we wish it to happen, when time elapses. Philosophy of time is a crucial factor in each one’s life. Life comes with it the opportunity to discover the livelihood of a person, to learn about anything, and to relate with nature. Modern society has an impact on the daily lives of individuals and therefore, the sense of efficiency result in increased responsibilities and tasks, which must be completed within a short time. No wonder Marcus Aurelius stated, "If you want to stop wasting your life in vain fantasies, perform every act in life as though it were your last," (Marcus Aurelius) to mean that people should not spend much of their time thinking of impossibilities, but rather use that chance to the maximum and to their best. People need to employ their time wisely, avoiding too much hurry to pause and taste life; they should never loss their sense of the extensive value of a single minute. In the Zen philosophy and time nature, William Blake is quoted attributing, - "The essence of Zen is to learn to do just one thing at a time" (William Blake). In my understanding, this implies that people ought to learn to live like ancient philosophers, by having specifications in their daily chores. Lacking this kind of philosophical thought of time may mess up an individual’s activities. Doing too much at ago violates the meaning and significance of how wisely a person should utilize time. Striving to achieve every goal at ago may only lead

How is a neuron like atoilet for therhold and all-or none properties Essay

How is a neuron like atoilet for therhold and all-or none properties - Essay Example The neurons are stimulated when they reach a specific level which is known as the threshold. Every neuron has its own threshold on which it can be stimulated. Below the threshold the neuron is not stimulated enough to fire impulses to cause its desired effect. This is known as the all or none property followed by all the neurons of the body. The threshold and the all or none law can be compared to the toilet. When the toilet is in the normal position without any interaction it is known to be in the resting position. This can be compared to the resting membrane potential of the neurons in which the neuron is not firing impulses. Similarly when the toilet has to be flushed the lever is to be pushed hard enough so that the flushing can begin. Same is the case with neurons which have a stimulatory threshold level which can only be achieved if the resting membrane potential has reached the threshold level. As the flush won’t work with the right power the neurons will also not work with the right stimulatory power. When the process of flushing starts it reaches a peak when the water stops being drained after which the water is poured back in the toilet.

Unit9 - Essay Example The course met my expectations as I was set on learning about analysis of policies and the in-depth detail was provided. The progress so far has been overwhelming. I did not expect that at this point I would have made much progress and learnt the much I have but the truth is that am way ahead and am immensely impressed by this progress. Despite the overwhelming progress and the making of leeway in the course, I still wish most of the concepts about the public policies analysis could have been carried out in slower manner to give time to really understand them since they impact directly on our day to day lives. All in all, the much taught though shallow still was good. To those students undertaking this course next year, I would advise them to start early preparations of trying to understand (though not fully) the main concepts in the course. This is in order to enable them have many questions which in the end makes the course be detailed with as many real life examples as possible hence making the course much more relevant to them. More interactive time and open forums with the tutor where debates about the course topics would have arisen and therefore made the course less intense would have been appreciated. This is because interactive time provides an avenue and time to get up close with the course instructor and hence opening communication channels to the shy students who are not so comfortable in intense classroom lectures and do better in an open forum sort-of discussion.

Aristotle and relationships at work Essay Example | Topics and Well Written Essays - 1750 words

Aristotle and relationships at work - Essay Example Happiness, to Aristotle, can easily be misjudged. Aristotle thought that people think happiness is a result of virtue, and through virtues like honor, pleasure and reason a human being can achieve happiness. But, according to Aristotle, this is not so: the pursuit of these does not equal happiness but leads one away from happiness. In actuality, happiness is achieved through self-sufficiency. But Aristotle clarifies this in his Nicomachean Ethics: â€Å"Now by self-sufficient we do not mean that is sufficient by a man himself, one which leads a solitary life, but also for parents, children, wife and in general for his friends and citizens (Aristotle 7).† Man is born of citizenship and through the adherence to the people he loves he will find happiness. But Nicomachean Ethics goes on to describe self-sufficiency as â€Å"that which when isolated makes one desirable, and lacking in nothing: and such we think happiness to be (Aristotle 8).† Happiness within self-sufficienc y is the end of action, not the experience of doing right by close members of friends and family, but the result of these actions. To Aristotle, happiness also has a â€Å"snowball effect.† Happiness comes from continuous good actions, and though a couple small blunders won’t make someone unhappy, per se, it is the combined results of good deeds and general goodness one achieves self-sufficiency and happiness. Though it is easy for a man to be distracted by the unhappiness or happiness of his fellow man, Aristotle continually emphasizes the fact that self-sufficiency, an independent motivator, should take precedence and one shouldn’t be flummoxed by the successes or failures of people around him. This could lead to unhappiness, and this lack of focus often does. One can certainly apply these ideas of Aristotalian happiness to

Connecting idea - Essay Example For instance, in the lives of Muslims, the use of the veil and hijab among women, has changed from time to time as they tried to survive in their communities. Along with this change was also the obvious adaptation in the commonly used English language. Such changes in the use of the veil and hijab as well as the English language will be discussed in more detail in the following paragraphs. In our world today, it is not uncommon to hear Muslim women being terrorized by non-Muslims saying that they are terrorists. For example, in the speech of Hafsah Badru Amirah, president of Muslim Students Society in Nigeria during the World Hijab Day in February, she reminded her audience that one of the reasons for the celebration is in remembrance of a Muslim woman stabbed to death in a German court for no other reason than wearing a hijab (Amirah). Hebah and Sarah, sisters from a Muslim family who migrated to America from Egypt, tell about their experiences about using the veil and hijab. They share about how people have always been fascinated by their way of dressing and how they have been threatened by strangers simply by the way they looked. For the non-Muslim who feels threatened by the presence of a Muslim woman wearing a hijab, it should be understood that such fear is also felt by the woman inside the strange costume. Nevertheless, that is not always the case so Muslims no w have differing opinions about their traditional clothing. For Hebah and Sarah, it is not a statement of their religion but it is their desire to obey Allah that they use hijab even in the face of dangers. However, in a world where they feel their sexuality is abused in a male-dominated workplace like in the case of Hebah, she feels the need to use the hijab as her way of saying, â€Å"I am a respectable woman† (Ali). Although there are Muslim women like Hebah and Sarah who would rather suffer the consequences of using

Would it be wiser to develop a new brand, or can it successfully market the same product to the under and over 50s? 6. What kind of subcultural (ethnic, race, age and sex) segmentation would best assist the marketer with the following products and services? 1. A digital microphone 2. An MP3 player 3. Jeans 4. Snap-chill meals 5. A new alcoholic lemonade 6. A tourist package to Vietnam and Pakistan . A personal telephone number 1. Some food goods, such as cans of pork, those people who are Moslem do not have pork and sometimes they substitute beef for pork. In this scenario, it has been of importance that manufacturers cannot produce the food associated with pork if they tend to target Moslem market. Otherwise, the customer of Moslem would be excluded. Take a Nutrilite as an example, it is a kind of nutritious medicine, like Blackmores in Au, it got different kinds of medicine, one of products is called protein powder that the people always going to gym should take after they finish the training. Also, for elders linked to the age subculture, the company produces each product in terms of some illness that is potential to them when they get older. Meanwhile, the likelihood of illness will decline if these aged people insist taking it. 2. Baby boomers: Those people are reaching the retirement age and they could be the largest customers using TV because they would spend lots of time at home. The company can give customers from the age of babyboomer some discounts once they plan to sign the contrast with Foxtel company duo to these people have potential to become the lasting customers. Generation X: consist of people born from 1965 to 1979, this group of people has accepted the higher education already and some of them work in a big company, earning higher salaries. Those people are in no rush to marry. For advertising companies, they should stress the advantage (eg. Credibility and naturalness of ingredients) of Paying TV services. The advertising company should attract these people since they like music, fashions and language. Generation Y: consist of people born between 1980 and 1994. Those people are more open to change and looking for next gadgets. These people use the internet almost everyday and the advertising company can have a try that linking the tv service to the internet. Also, this group of people is characterized by the informal groups, like friends and they prefer to imitate what friends do. 3. The business can give the elders discount if they purchase the necessity, such as walking stick. Particularly, if some elders make a consumed decision, such as buy a new car, then the government should cut the tax rate that elders should pay by the mortgage or cash. The allowance given to elderly depends on what sort of decisions they make and the income earn. 4 I think the oil of ulan should develop a new product since customers between 50 and over-50s have different skin. For instance, the skin with elders has more wrinkles and the company should design specific products for the people who are more than 50. The company can not market the same product but can develop a new brand that is a branch of Oil of Ulan. As a result, the two brands can segment different groups of customers and position the products. . A digital microphone and an mp3 player) age.

Design and Planning of 2G, 3G and Channel Modelling of 4G

Design and Planning of 2G, 3G and Channel Modelling of 4G Chapter 1 Fundamentals of Cellular Communication In this chapter, all the background knowledge which is required for this project has been discussed. 1.1 Cell The area covered by single BTS(base transceiver station) is known as cell. 1.1.1 Shape of cell The shape of cell depends upon the coverage of the base station. The actual coverage of the base station is called footprint and is found with the help of measurements from the field. We can make our calculations easier by using the shape of circle noting that there would not be spaces between them. As, the purpose is to provide coverage to each and every subscriber. But if there are spaces between the coverage areas then the person in that specific area will not be able to get any coverage. To cover the problem of interleaving spaces, the shapes that can be used theoretically are: Square Triangle Hexagon But in selection criteria one thing must be kept in mind that every person within a cell get same coverage specially the person at the edges of the cell. So hexagon is the shape among these three choices with largest coverage area. Its coverage area and shape is closest to the circle and it helps tessellate. Omnidirectional antenna is used in the center of it, and if we want to use sectored directional antenna then it must be used at any three corners of it. 1.1.2 Area of the Cell The area of a cell with radius R is shown in figure 1.1(a), is given by: 1.2 Frequency planning While developing the cellular system, it has limited capacity due to the given bandwidth. So, in order to solve this problem Cellular Systems have to depends on an intelligent and more use of channels through out the area. Every cellular base station is alloted a group of different radio channels to be used in a cell. Base station in the adjacent cells use completely different frequencies. For this purpose antennas are used such that their power may get limited within the cell. In this way the allocated frequencies maybe reused in different cells again. The process of allocating and selecting channel groups for all the base stations in a system is known as frequency reuse or frequency planning. We use two types of antennas: Omnidirectional antenna Sectored directional antenna Omnidirectional antennas are used in the cells which are centrally excited and sectored directional antennas are used in the edge excite cells. To understand the concept of frequency reuse, let us say that S are the total no. of duplex channels available for use, k number of channels given to each cell i.e. k S=kN (1.2) Where N is no. of cells which uses the complete set of available frequencies known as cluster frequency reuse factor (1.3) Each cell is in the cluster is assigned of the available channels. The radio frequency from 3Hz to 3000GHz are separated into 12 bands, as shown in the table. Frequency spectrum has different propagation characteristics. As far as concerned to the mobile communication, we only pay attention to the UHF spectrum. 1.2.1 Cluster size(N) If we use N large (a large cluster), the ratio of the cell radius and the distance between co-channel decreases, which causes weaker co-channel interference. But if N is smaller, by keeping the cell size same then we more clusters are needed to cover an area. Hence the capacity is increased. So if we use N larger then the quality of voice is good but the capacity is less and vice versa. 1.3 Interference Interference is one of the major factor in the capacity and performance of a cellular network. The interference is due to a call in the neighbouring cell, another base station operating in the same frequency. Interference causes crosstalk and noise. There are two types of interference. Adjacent channel interference Co-channel interference 1.3.1 Adjacent channel interference Adjacent channel interference results from the signals which are side by side in frequencies to the desires signal. Adjacent channel interference is caused by wrong filtering, like incomplete filtering of not wanted modulation in frequency modulation (FM) systems, not proper tuning, or poor control of frequency. It causes problem. Adjacent channel interference can be reduced by careful channel assignment, filtering and power control within a cell. 1.3.2 Co-channel interference Co-channel cells are the cell which use the same set of frequencies. For example, in the figure 1.2 all the letter ‘A are the co-channel cell because they use the same set of frequencies. Interference due to the co-channel cells is called co-channel interference. It can be reduced by using greater value of N(cluster size). If D is the distance between the co-channel cells and R is radius of the cell, then by using greater value of N the ratio between D to R is increased hence reducing co-channel interference. The relation can b written as: 1.4 Improving coverage and capacity The number of channels assigned to a cell became insufficiently as the demand of wireless system increases. To provide more channels per coverage, some techniques are introduced which improve the coverage and capacity. These techniques are: Cell splitting Sectoring Microcell zone concept 1.4.1 Cell Splitting Cell splitting is the process of dividing a cell into smaller cells. In this process we reduce the antenna height and power of the base station. Cell splitting increases the capacity by increasing frequency reuse factor. In cell splitting Channel assignment techniques remain the same. SIR remains the same Trunking inefficiency do not get suffer. Trunking efficiency is the measure of the number of users which can be offered a particular Grade of service with the specific configuration of the channels. The grade of service (GOS) is the measure of the ability to access a trunked system during the busy hours. The radius of the new cell is reduce to half. So power is also reduced. 1.4.2 Sectoring Sectoring uses directional antennas for controlling the interferences and frequency reuse of channels. The co-channel interference is reduced and thus increasing system performance by using directional antenna. A cell is normally divided into three 120 sectors or six 60 °sectors. When sectoring is used, the channels used in a particular cell are broken into sectored groups and are used only within a particular sector. The no. of channels get divided into sectored groups, so the trunking efficiency is reduced. In sectoring SIR is improved by reducing interference and trunking efficiency is reduced. Handoff increased in sectoring. The s/I improvement allows to decrease the cluster size N in order to improve the frequency reuse, and thus the system capacity. Further improvements in s/I is achieved by downtilting the sector antennas. 1.4.3 Microcell Zone Concept Microcell Zone concept distributes the coverage of a cell and extends the cell boundry to hard to reach places. It maintains the S/I and trunking efficiency, and increases the coverage and capacity of an area. 1.5 Radio wave propagation Radio waves propagate through different channels and by different ways to reach the MS(Mobile Station). It also depends upon the speed of the wave. The propagation of radio waves depends into two types: Large scale propagation Small scale propagation(Fading) 1.5.1 Large scale propagation The model predicts that the average signal strength for all transmitter-receiver (TR) distance on a scale known as large scale propogation model. 1.5.2 Small scale propagation The models that predicts the rapid fluctuation of the received signal strength over a short distance known as small scale propagation model or fading. 1.5.3 Free Space Propagation Model The free space propagation model is used when the transmitter and receiver have line of sight (LOS) between them to predict the received signal strength. Where Pr = received power. Pt = transmitted power, Gt and Gr = transmitter and receiver antenna gain, do= T-R separation, L = system loss factor ÃŽ » = wavelength. 1.6 Propagation Mechanisms The propagation mechanisms which effect propagation are: Reflection Scattering Diffraction Reach directly (in case of Line of Sight) If there is line of sight signal reach the Mobile station directly and signal power is very strong. 1.6.1 Reflection Reflection occurs when an electromagnetic wave falls upon an object which is large as compare to the wavelength of the wave. It occurs from buildings, walls, surface of earth etc. 1.6.2 Diffraction Diffraction happens when the path between the transmitters and receivers is disturbed by a surface with sharp edges. It source is any sharp edge object. Knife edge diffraction Model is used for diffraction. 1.6.3 Scattering Scattering occurs when an electromagnetic wave falls upon an object which has small dimension as compared to the wavelength of the wave. Scattering occurs due to small objects, rough surfaces or any irregularities. Objects such as lamp posts, trees scatter the radio waves. Radar Cross Section Model is used for sectoring. 1.7 Small Scale Fading Fading is the fluctuation in the received signal strength over very short distance. Fading is due to reception of different versions of same signals. Following are the factors which influence Small-Scale Fading are: Multipath propagation: Due to absence of LOS signal follows the multipath due to reflection, diffraction, scattering. Speed of the mobile: Fading also accurs due to the movement of the mobile as the signal strength changes. Speed of the surrounding objects: Fading also occurs due to the movement of mobile, if the speed of the surrounding object is much faster then the speed of the mobile then it also induces Doppler shift. The transmission BW (bandwidth) of the signal: The received signal is distorted if the transmitted signal bandwidth is greater than the bandwidth of the channel. 1.8 GSM The first GSM network was launched in 1991. The GSM network was structured hierarchically. It consists of one administrative region, which is assigned to MSC. Each administrative region is consists of at least one location area (LA). LA is also called the visited area. An LA consists of several cell groups. Each cell group is assigned to a base station controller (BSC). Cells of one BSC may belong to different LAs. GSM distinguishes explicitly between users and identifiers. The user identity associates with a MS by mans of personal chip cards, the subscriber identity module (SIM). The SIM is portable and transferable MSs. The mobile Roaming number is a temporary location-dependent ISDN number. It is assigned by a locally responsible Visited Location Number (VLR). The GSM network can defined into four major parts. Mobile station (MS). Base station Sub-system (BSS). Network and switching Sub-system (NSS). Operation and support Sub-system (OSS). 1.8.1 Mobile station A mobile station consists of two parts. Mobile equipment and terminal. Subscriber identity module (SIM). 1.8.2 THE Terminal There are different types of terminal distinguished principally by their power and application: The fixed terminals are installed in cars. The GSM portable terminals can be used in the vehicles. The hand held terminals have experienced a biggest success depending upon their weight and volume, which are decreasing continuously. These terminals can emit power of 2 w. The evolution of technologies decreases the maxpower to 0.8 watts. 1.8.3 SIM Sim is a smart card which identifies the terminal. Using the sim card in the mobile, the user can access all the services provided by the provider. Terminal does not operate without the sim,. Personal identification number(PIN) helps protect sim. 1.9 The Base Station Subsystem The BSS connects the MS to Network Switching Sub-system. It is incharge of transmission as well as reception. The BSS is further divided into two main parts. Base transceiver station (BTS) or base station. Base Station Controller(BSC). 1.9.1 The Base Transceiver Station The BTS deals with the transceivers and antennas which are used in each cell of a network. BTS is usually in the center of cell. Size of the cell is defined by its transmitting power. Each BTS has one to sixteen transceivers which depends upon the density of users. 1.10 The Base Station Controller The BSC controllers the group of BTS and manages radio resources. The BSC is incharge of handover, frequency hoping and exchange of radio frequency power level of BTSs. 1.11 The Network and Switching Subsystem It is to manage the communication between mobile and other users, such as ISDN users, telephony users. It store the information in data bases about the subscriber and manage their mobility. 1.12 The Mobile Services Switching Center (MSC) It is the central component of the NSS. Network Switching Functions are performed by the MSC. It provides connection to more other networks. Chapter 2 Planning One of the important phase of the project in which all the detail information is gathered about different areas and their population including city boundary, market analysis and roads are the key features in these details are city profiling. This phase is divided into different tasks. 2.1 Lahore City Map First is to get the detailed map of the Lahore city, which includes all the aspects related to the project. These are following:- Area division Dense area Sub-urban area open area Boundaries of City 2.2 Boundary Marking The project â€Å"Radio Frequency Planning † is basically the frequency planning of the city, not to its belongings areas. The exact boundary of the city is marked in order to concentrate on the marked area. 2.3 Population Population of the city plays an important role in the frequency planning. It helps a lot in the estimations and assumptions. The population of the city is around 10 million. 2.4 Estimations and Assumptions This part is mainly concerned with the frequency planning. When a new telecommunication company comes in the market, it estimates it users. This estimation is done with respect to the total population of the particular area. The estimations are done to estimate the users on urban, suburban and open areas. 2.5 Area Division The area division depends upon the percentage of population in an area and type of area as it is the important factor in the site as wall as frequency planning. The Lahore city is divided into three major areas. 2.5.1 Urban Area Urban area is an area which is surrounded by more density of humans and structures in comparison to the areas surrounding it 2.5.2 Sub-Urban Area Suburban area is districts located either inside a town or citys outer premises or just outside its limits. 2.5.3 Open Area Open area is partially settled places away from the large cities. Such areas are different from more intensively settled urban and suburban areas. There are less population as compared to urban and sub-urban areas. 2.6 Site Planning 2.6.1 Map of Lahore 2.6.2 Urban Area 2.6.3 Sub-Urban Area 2.6.4 Open Area HATA Model for Urban Area = Path loss in Urban Areas in decibel (dB) = Height of base station in meters (m) = Height of mobile station Antenna in meters (m) = Frequency of Transmission in megahertz (MHz). = Distance between the base station and mobile stations in kilometers To calculate radius of a site of Urban Area For Downlink =-75 dBm(this power covers both indoor and outdoor coverage range -70 to -90 dBm ) = 35 m(Average height of antenna in city is 30 to 200 m) = 1.5 m = 13 dBm = 46 dBm (Max Power transmitted by Base Station) = Cable loss = 2.01 dBm = 945 Mhz (Downlink frequency 935 to 960 MHz) = Combine Loss= 5.5 dBm Putting in HATA equation For Uplink = -102 dbm(Min Power received by Base Station) = 29.1 dBm (Max transmitted power mobile) = 900 MHz (890 to 915 MHz) Putting in HATA equation We will be using d=0.90 Km as it covers both Uplink and Downlink. For Sub-Urban Area For Downlink For downlink of Suburban parameters are same as for Urban. For Uplink Uplink parameters are also same as Urban Areas We will be using d=2.32 Km for Suburban Area. For Open Areas Downlink For downlink parameters are same as Urban Areas For Uplink We will be using d=8 for Open Areas. We will be using 65 degree directional Antennas. Angle between 2 consecutive lobes is 120 degree. r=Radius of lobes For Full Lobe For All 3 Lobes Area of site in Urban Area of site in Suburban Area of site in Fields(Open Area) Calculations for Number of BTS 2.7 Frequency Planning One of the breakthrough in solving the problem of congestion and user capacity is the cellular concept. Cellular radio systems rely on reuse of channels throughout a coverage region. A group of radio channels are allocated to each cellular base station to be used within a area known as cell. Different channels are assingned in the adjacent cells of the base station. The same group of channels can be used by limiting the coverage area, within the boundaries of a cell to cover different levels, within tolerable limits. Frequency planning is the design process of selecting, allocating or assinging channel group stations within a system. The theoretical calculations, and fixed size of a cell is assumed, that can differentiate no of channels in a cell and from that can differentiate cluster size and will differ, the capacity of the cellular system. There is a trade between the interference abd capacity in theoretical calculation as if we reduce the cluster size more cells are needed to cover the area and more capacity. But from another perceptive small cluster size causes the ratio between cell radius, and the distance between co-channels cells to increase, leading to stronger co-channels interference. In practical calculations, a fixed no of channels are allocated to a cell. One channel per lobe 3channels are allocated to a cell. The capacity can be increased by allocating 2 channels per lobe or 6 channels per cell. But after allocating channels once, they will remain fixed for the whole cellular system and frequency planning. Now as with the fixed no of channels as per cell, the capacity will remain constant of the system and we can achieve weaker co-channel interference, by having a small cluster size(N). A cluster size of 7 is selected in this project, which is also discussed. So in later practical world , there is not a trade-off between capacity and co-channel interference. 2.7.1 Calculations The city of Lahore is divided into 120 cells. We take 3 channels per cell that gives us 1 cell = 3 channels Reuse factor = 1/N = 1/7 Which means that frequency can be reused after a cluster of 7 cells. That gives us the total of 7 x 3 =21+ 2(guard cells)=23 channels We will be using 23 channels with a reuse factor of 1/7. 2.8 Implementation in GAIA Figure 2.1 is a snapshot of GAIA planning tool showing us the structure of an urban area. This figure illustrates the urban boundary which we calculate during city profiling. It also shows the antenna system used, in this case 3 sectors with 120 degree azimuth spacing is used. Antennas are installed on the rooftop of buildings or houses due to dense population and to provide a better coverage. Figure 2.2 shows us the planning of a Sub-Urban area with sites more distance apart as population is less, compared to urban. In Sub-Urban 3 sector cell is used which is similar to the ones used in Urban Figure 2.3 shows us the coverage planning of a network in an open area. Here the sites are further apart as open area has least population. 3 sector cell is used with the antennas installed above a steel structure for better coverage. Figure 2.4 shows the sector wise cell area of the sites in the urban area of the city in GAIA, which can be differentiated with the help of different color for each sector, also it shows the coverage area of every site. We have used grid approach in this planning, it is the most widely used and most effective technique used theoretically and practically. Figure 2.5 shows the cell boundary of sites in Sub-urban area of the city. Figure 2.6 shows the cell boundary in the open area of the city. Figure 2.7 illustrates the signal strength in the urban area of the city. Because of the dense population the signal power is strong throughout to ensure high quality calls to the subscribers with minimum interference and call drop. Figure 2.8 shows the 2G signal strength in the Sub-urban areas where population density is low and so the power required is less as compared to urban areas. Figure 2.9 shows the serving signal strength in open area. The signal is the weakest as there is the least number of people in open area. CHAPTER 3 FUNDAMENTALS OF 3G 3.1 INTRODUCTION The Universal Mobile Telephony System (UMTS) or 3G as it is known is the next big thing in the world of mobile telecommunications. It provides convergence between mobile telephony broadband access and Internet Protocol (IP) backbones. This introduces very variable data rates on the air interface, as well as the independence of the radio access infrastructure and the service platform. For users this makes available a wide spectrum of circuit-switched or packet data services through the newly developed high bit rate radio technology named Wideband Code Division Multiple Access (WCDMA). The variable bit rate and variety of traffic on the air interface have presented completely new possibilities for both operators and users, but also new challenges to network planning and optimization. The success of the technology lies in optimum utilization of resources by efficient planning of the network for maximum coverage, capacity and quality of service. This part of our project aims to detail method of UMTS Radio Network (UTRAN) Planning. The new technologies and services have brought vast changes within the network planning; the planning of a 3G network is now a complex balancing act between all the variables in order to achieve the optimal coverage, capacity and Quality of Service simultaneously. 3.2 WCDMA In UMTS access scheme is DS-CDMA (Direct Sequence CDMA) which involves that a code sequence is directly used to modulate the transmitted radio signal with information which is spreaded over approximately 5 MHz bandwidth and data rate up to 2 Mbps. Every user is assigned a separate code/s depending upon the transaction, thus separation is not based on frequency or time but on the basis of codes. The major advantage of using WCDMA is that there is no plan for frequency re-use. 3.3 NODE B Node B functions as a RBS (Radio Base Station) and provides radio coverage to a geographical area, by providing physical radio link between the UE (User Equipment) and the network. Node B also refer the codes that are important to identify channels in a WCDMA system. It contains the RF transceiver, combiner, network interface and system controller, timing card, channel card and backplane. The Main Functions of Node B are: Closed loop power control CDMA Physical Channel coding Modulation /Demodulation Micro Diversity Air interface Transmission /Reception Error handling Both FDD and TDD modes are supported by Single node B and it can be co-located with a GSM BTS to reduce implementation costs. The conversion of data from the Radio interface is the main task of Node B. It measures strength and quality of the connection. The Node B participates in power control and is also responsible for the FDD softer handover. On the basis of coverage, capacity and antenna arrangement Node B can be categorizes as Omni directional and Sectorial: OTSR (Omni Transmitter Sector Receiver) STSR (Sector Transmitter Sector Receiver) 3.3.1 OTSR (Omni Transmit Sector Receive) The OTSR configuration uses a single (PA) Power Amplifier, whose output is fed to a transmit splitter. The power of the RF signal is divided by three and fed to the duplexers of the three sectors, which are connected to sectorized antennas. 3.3.2 STSR (Sectorial Transmit Sector Receive) The STSR configuration uses three (PA) Power Amplifier, whose output is fed directly to the duplexers of the three sectors, which are connected to sectorized antennas. Node B serve the cells which depend on sectoring. 3.4 ACCESS MODES 3.4.1 FDD (Frequency Division Duplex) A duplex method whereby uplink and downlink transmissions use two separated radio frequencies. In the FDD, each downlink and uplink uses the different frequency band. 3.4.2 TDD (Time Division Duplex) It is a method in which same frequency is used for the transmission of downlink and uplink by using synchronized time intervals. Time slots are divided into transmission and reception part in the physical channel. 3.4.3 Frequency Bands 3.4 CELLULAR CONCEPT The UMTS network is third generation of cellular radio network which operate on the principle of dividing the coverage area into zones or cells (node B in this case), each of which has its own set of resources or transceivers (transmitters /receivers) to provide communication channels, which can be accessed by the users of the network. A cell is created by transmitting numerous number of low power transmitters. Cell size is determined by the different power levels according to the subscriber demand and density within a specific region. Cells can be added to accommodate growth. Communication in a cellular network is full duplex, which is attained by sending and receiving messages on two different frequencies. In order to increase the frequency reuse capability to promote spectrum efficiency of a system, it is desirable to reuse the same channel set in two cells which are close to each other as possible, however this increases the probability of co-channel interference . The performance of cellular mobile radio is affected by co channel interference. Co-channel interference, when not minimized, decreases the ratio of carrier to interference powers (C/I) at the periphery of cells, causing diminished system capacity, more frequent handoffs, and dropped calls. Usually cells are represented by a hexagonal cell structure, to demonstrate the concept, however, in practice the shape of cell is determined by the local topography. 3.4.1 Types of Cell The 3G network is divided on the basis of size of area covered. Micro cell the area of intermediate coverage, e.g., middle of a city. Pico cell the area of smallest coverage, e.g., a hot spot in airport or hotel. Macro cell the area of largest coverage, e.g., an complete city. 3.5 FADING Fading is another major constraint in wireless communication. All signals regardless of the medium used, lose strength this is known as attenuation/fading. There are three types of fading: Pathloss Shadowing Rayleigh Fading 3.5.1 Pathloss Pathloss occurs as the power of the signal steadily decreases over distance from the transmitter. 3.5.2 Shadowing Shadowing or Log normal Fading is causes by the presence of building, hills or even tree foilage. 3.5.3 Rayleigh Fading Rayleigh Fading or multipath fading is a sudden decrease in signal strength as a result of interference between direct and reflected signal reaching the mobile station. 3.6 HANDOVER IN CDMA The term handover or handoff refers to the process of transferring data session or an ongoing call from channel to channel connected to the core network to another. The handover is performed due to the mobility of a user that can be served in another cell more efficiently. Handover is necessary to support mobility of users. Handover are of following types (also known as handoff): Hard Handover Soft Handover Softer Handover 3.6.1Hard.Handover In Hard handover the old radio links in the UE are dispose of before the new radio links takes place. It can be either seamless or non-seamless. In seamless hard handover, the handover is not detected by the user. A handover that needs a change of the carrier frequency is a hard handover. 3.6.2Soft.Handover Soft handover takes place when cells on the same frequency are changed. Atleast one radio link is always kept to the UTRAN in the removal and addition of the radio links. It is opperated by means of macro diversity in which many radio links are active. 3.6.3Softer.handover It is one of the important case of soft handover which describe the removal and addition of the radio links which is being belonged by the same Node B. Macro diversity can be performed in the NODE B with maximum ratio combining in softer handover. There are inter-cell and intra-cell handover. Handover 3G 2G (e.g. handover to GSM) FDD inter-frequency hard handover TDD/FDD handover (change of cell) TDD/TDD handover FDD/TDD handover (chan Design and Planning of 2G, 3G and Channel Modelling of 4G Design and Planning of 2G, 3G and Channel Modelling of 4G Chapter 1 Fundamentals of Cellular Communication In this chapter, all the background knowledge which is required for this project has been discussed. 1.1 Cell The area covered by single BTS(base transceiver station) is known as cell. 1.1.1 Shape of cell The shape of cell depends upon the coverage of the base station. The actual coverage of the base station is called footprint and is found with the help of measurements from the field. We can make our calculations easier by using the shape of circle noting that there would not be spaces between them. As, the purpose is to provide coverage to each and every subscriber. But if there are spaces between the coverage areas then the person in that specific area will not be able to get any coverage. To cover the problem of interleaving spaces, the shapes that can be used theoretically are: Square Triangle Hexagon But in selection criteria one thing must be kept in mind that every person within a cell get same coverage specially the person at the edges of the cell. So hexagon is the shape among these three choices with largest coverage area. Its coverage area and shape is closest to the circle and it helps tessellate. Omnidirectional antenna is used in the center of it, and if we want to use sectored directional antenna then it must be used at any three corners of it. 1.1.2 Area of the Cell The area of a cell with radius R is shown in figure 1.1(a), is given by: 1.2 Frequency planning While developing the cellular system, it has limited capacity due to the given bandwidth. So, in order to solve this problem Cellular Systems have to depends on an intelligent and more use of channels through out the area. Every cellular base station is alloted a group of different radio channels to be used in a cell. Base station in the adjacent cells use completely different frequencies. For this purpose antennas are used such that their power may get limited within the cell. In this way the allocated frequencies maybe reused in different cells again. The process of allocating and selecting channel groups for all the base stations in a system is known as frequency reuse or frequency planning. We use two types of antennas: Omnidirectional antenna Sectored directional antenna Omnidirectional antennas are used in the cells which are centrally excited and sectored directional antennas are used in the edge excite cells. To understand the concept of frequency reuse, let us say that S are the total no. of duplex channels available for use, k number of channels given to each cell i.e. k S=kN (1.2) Where N is no. of cells which uses the complete set of available frequencies known as cluster frequency reuse factor (1.3) Each cell is in the cluster is assigned of the available channels. The radio frequency from 3Hz to 3000GHz are separated into 12 bands, as shown in the table. Frequency spectrum has different propagation characteristics. As far as concerned to the mobile communication, we only pay attention to the UHF spectrum. 1.2.1 Cluster size(N) If we use N large (a large cluster), the ratio of the cell radius and the distance between co-channel decreases, which causes weaker co-channel interference. But if N is smaller, by keeping the cell size same then we more clusters are needed to cover an area. Hence the capacity is increased. So if we use N larger then the quality of voice is good but the capacity is less and vice versa. 1.3 Interference Interference is one of the major factor in the capacity and performance of a cellular network. The interference is due to a call in the neighbouring cell, another base station operating in the same frequency. Interference causes crosstalk and noise. There are two types of interference. Adjacent channel interference Co-channel interference 1.3.1 Adjacent channel interference Adjacent channel interference results from the signals which are side by side in frequencies to the desires signal. Adjacent channel interference is caused by wrong filtering, like incomplete filtering of not wanted modulation in frequency modulation (FM) systems, not proper tuning, or poor control of frequency. It causes problem. Adjacent channel interference can be reduced by careful channel assignment, filtering and power control within a cell. 1.3.2 Co-channel interference Co-channel cells are the cell which use the same set of frequencies. For example, in the figure 1.2 all the letter ‘A are the co-channel cell because they use the same set of frequencies. Interference due to the co-channel cells is called co-channel interference. It can be reduced by using greater value of N(cluster size). If D is the distance between the co-channel cells and R is radius of the cell, then by using greater value of N the ratio between D to R is increased hence reducing co-channel interference. The relation can b written as: 1.4 Improving coverage and capacity The number of channels assigned to a cell became insufficiently as the demand of wireless system increases. To provide more channels per coverage, some techniques are introduced which improve the coverage and capacity. These techniques are: Cell splitting Sectoring Microcell zone concept 1.4.1 Cell Splitting Cell splitting is the process of dividing a cell into smaller cells. In this process we reduce the antenna height and power of the base station. Cell splitting increases the capacity by increasing frequency reuse factor. In cell splitting Channel assignment techniques remain the same. SIR remains the same Trunking inefficiency do not get suffer. Trunking efficiency is the measure of the number of users which can be offered a particular Grade of service with the specific configuration of the channels. The grade of service (GOS) is the measure of the ability to access a trunked system during the busy hours. The radius of the new cell is reduce to half. So power is also reduced. 1.4.2 Sectoring Sectoring uses directional antennas for controlling the interferences and frequency reuse of channels. The co-channel interference is reduced and thus increasing system performance by using directional antenna. A cell is normally divided into three 120 sectors or six 60 °sectors. When sectoring is used, the channels used in a particular cell are broken into sectored groups and are used only within a particular sector. The no. of channels get divided into sectored groups, so the trunking efficiency is reduced. In sectoring SIR is improved by reducing interference and trunking efficiency is reduced. Handoff increased in sectoring. The s/I improvement allows to decrease the cluster size N in order to improve the frequency reuse, and thus the system capacity. Further improvements in s/I is achieved by downtilting the sector antennas. 1.4.3 Microcell Zone Concept Microcell Zone concept distributes the coverage of a cell and extends the cell boundry to hard to reach places. It maintains the S/I and trunking efficiency, and increases the coverage and capacity of an area. 1.5 Radio wave propagation Radio waves propagate through different channels and by different ways to reach the MS(Mobile Station). It also depends upon the speed of the wave. The propagation of radio waves depends into two types: Large scale propagation Small scale propagation(Fading) 1.5.1 Large scale propagation The model predicts that the average signal strength for all transmitter-receiver (TR) distance on a scale known as large scale propogation model. 1.5.2 Small scale propagation The models that predicts the rapid fluctuation of the received signal strength over a short distance known as small scale propagation model or fading. 1.5.3 Free Space Propagation Model The free space propagation model is used when the transmitter and receiver have line of sight (LOS) between them to predict the received signal strength. Where Pr = received power. Pt = transmitted power, Gt and Gr = transmitter and receiver antenna gain, do= T-R separation, L = system loss factor ÃŽ » = wavelength. 1.6 Propagation Mechanisms The propagation mechanisms which effect propagation are: Reflection Scattering Diffraction Reach directly (in case of Line of Sight) If there is line of sight signal reach the Mobile station directly and signal power is very strong. 1.6.1 Reflection Reflection occurs when an electromagnetic wave falls upon an object which is large as compare to the wavelength of the wave. It occurs from buildings, walls, surface of earth etc. 1.6.2 Diffraction Diffraction happens when the path between the transmitters and receivers is disturbed by a surface with sharp edges. It source is any sharp edge object. Knife edge diffraction Model is used for diffraction. 1.6.3 Scattering Scattering occurs when an electromagnetic wave falls upon an object which has small dimension as compared to the wavelength of the wave. Scattering occurs due to small objects, rough surfaces or any irregularities. Objects such as lamp posts, trees scatter the radio waves. Radar Cross Section Model is used for sectoring. 1.7 Small Scale Fading Fading is the fluctuation in the received signal strength over very short distance. Fading is due to reception of different versions of same signals. Following are the factors which influence Small-Scale Fading are: Multipath propagation: Due to absence of LOS signal follows the multipath due to reflection, diffraction, scattering. Speed of the mobile: Fading also accurs due to the movement of the mobile as the signal strength changes. Speed of the surrounding objects: Fading also occurs due to the movement of mobile, if the speed of the surrounding object is much faster then the speed of the mobile then it also induces Doppler shift. The transmission BW (bandwidth) of the signal: The received signal is distorted if the transmitted signal bandwidth is greater than the bandwidth of the channel. 1.8 GSM The first GSM network was launched in 1991. The GSM network was structured hierarchically. It consists of one administrative region, which is assigned to MSC. Each administrative region is consists of at least one location area (LA). LA is also called the visited area. An LA consists of several cell groups. Each cell group is assigned to a base station controller (BSC). Cells of one BSC may belong to different LAs. GSM distinguishes explicitly between users and identifiers. The user identity associates with a MS by mans of personal chip cards, the subscriber identity module (SIM). The SIM is portable and transferable MSs. The mobile Roaming number is a temporary location-dependent ISDN number. It is assigned by a locally responsible Visited Location Number (VLR). The GSM network can defined into four major parts. Mobile station (MS). Base station Sub-system (BSS). Network and switching Sub-system (NSS). Operation and support Sub-system (OSS). 1.8.1 Mobile station A mobile station consists of two parts. Mobile equipment and terminal. Subscriber identity module (SIM). 1.8.2 THE Terminal There are different types of terminal distinguished principally by their power and application: The fixed terminals are installed in cars. The GSM portable terminals can be used in the vehicles. The hand held terminals have experienced a biggest success depending upon their weight and volume, which are decreasing continuously. These terminals can emit power of 2 w. The evolution of technologies decreases the maxpower to 0.8 watts. 1.8.3 SIM Sim is a smart card which identifies the terminal. Using the sim card in the mobile, the user can access all the services provided by the provider. Terminal does not operate without the sim,. Personal identification number(PIN) helps protect sim. 1.9 The Base Station Subsystem The BSS connects the MS to Network Switching Sub-system. It is incharge of transmission as well as reception. The BSS is further divided into two main parts. Base transceiver station (BTS) or base station. Base Station Controller(BSC). 1.9.1 The Base Transceiver Station The BTS deals with the transceivers and antennas which are used in each cell of a network. BTS is usually in the center of cell. Size of the cell is defined by its transmitting power. Each BTS has one to sixteen transceivers which depends upon the density of users. 1.10 The Base Station Controller The BSC controllers the group of BTS and manages radio resources. The BSC is incharge of handover, frequency hoping and exchange of radio frequency power level of BTSs. 1.11 The Network and Switching Subsystem It is to manage the communication between mobile and other users, such as ISDN users, telephony users. It store the information in data bases about the subscriber and manage their mobility. 1.12 The Mobile Services Switching Center (MSC) It is the central component of the NSS. Network Switching Functions are performed by the MSC. It provides connection to more other networks. Chapter 2 Planning One of the important phase of the project in which all the detail information is gathered about different areas and their population including city boundary, market analysis and roads are the key features in these details are city profiling. This phase is divided into different tasks. 2.1 Lahore City Map First is to get the detailed map of the Lahore city, which includes all the aspects related to the project. These are following:- Area division Dense area Sub-urban area open area Boundaries of City 2.2 Boundary Marking The project â€Å"Radio Frequency Planning † is basically the frequency planning of the city, not to its belongings areas.

The Lahore city is divided into three major areas. 2.5.1 Urban Area Urban area is an area which is surrounded by more density of humans and structures in comparison to the areas surrounding it 2.5.2 Sub-Urban Area Suburban area is districts located either inside a town or citys outer premises or just outside its limits. 2.5.3 Open Area Open area is partially settled places away from the large cities. Such areas are different from more intensively settled urban and suburban areas. There are less population as compared to urban and sub-urban areas. 2.6 Site Planning 2.6.1 Map of Lahore 2.6.2 Urban Area 2.6.3 Sub-Urban Area 2.6.4 Open Area HATA Model for Urban Area = Path loss in Urban Areas in decibel (dB) = Height of base station in meters (m) = Height of mobile station Antenna in meters (m) = Frequency of Transmission in megahertz (MHz). = Distance between the base station and mobile stations in kilometers To calculate radius of a site of Urban Area For Downlink =-75 dBm(this power covers both indoor and outdoor coverage range -70 to -90 dBm ) = 35 m(Average height of antenna in city is 30 to 200 m) = 1.5 m = 13 dBm = 46 dBm (Max Power transmitted by Base Station) = Cable loss = 2.01 dBm = 945 Mhz (Downlink frequency 935 to 960 MHz) = Combine Loss= 5.5 dBm Putting in HATA equation For Uplink = -102 dbm(Min Power received by Base Station) = 29.1 dBm (Max transmitted power mobile) = 900 MHz (890 to 915 MHz) Putting in HATA equation We will be using d=0.90 Km as it covers both Uplink and Downlink.

Different channels are assingned in the adjacent cells of the base station. The same group of channels can be used by limiting the coverage area, within the boundaries of a cell to cover different levels, within tolerable limits. Frequency planning is the design process of selecting, allocating or assinging channel group stations within a system. The theoretical calculations, and fixed size of a cell is assumed, that can differentiate no of channels in a cell and from that can differentiate cluster size and will differ, the capacity of the cellular system. There is a trade between the interference abd capacity in theoretical calculation as if we reduce the cluster size more cells are needed to cover the area and more capacity. But from another perceptive small cluster size causes the ratio between cell radius, and the distance between co-channels cells to increase, leading to stronger co-channels interference. In practical calculations, a fixed no of channels are allocated to a cell. One channel per lobe 3channels are allocated to a cell. The capacity can be increased by allocating 2 channels per lobe or 6 channels per cell.

Now as with the fixed no of channels as per cell, the capacity will remain constant of the system and we can achieve weaker co-channel interference, by having a small cluster size(N). A cluster size of 7 is selected in this project, which is also discussed. So in later practical world , there is not a trade-off between capacity and co-channel interference. 2.7.1 Calculations The city of Lahore is divided into 120 cells. We take 3 channels per cell that gives us 1 cell = 3 channels Reuse factor = 1/N = 1/7 Which means that frequency can be reused after a cluster of 7 cells. That gives us the total of 7 x 3 =21+ 2(guard cells)=23 channels We will be using 23 channels with a reuse factor of 1/7. 2.8 Implementation in GAIA Figure 2.1 is a snapshot of GAIA planning tool showing us the structure of an urban area. This figure illustrates the urban boundary which we calculate during city profiling. It also shows the antenna system used, in this case 3 sectors with 120 degree azimuth spacing is used. Antennas are installed on the rooftop of buildings or houses due to dense population and to provide a better coverage. Figure 2.2 shows us the planning of a Sub-Urban area with sites more distance apart as population is less, compared to urban. In Sub-Urban 3 sector cell is used which is similar to the ones used in Urban Figure 2.3 shows us the coverage planning of a network in an open area. Here the sites are further apart as open area has least population. 3 sector cell is used with the antennas installed above a steel structure for better coverage. Figure 2.4 shows the sector wise cell area of the sites in the urban area of the city in GAIA, which can be differentiated with the help of different color for each sector, also it shows the coverage area of every site. We have used grid approach in this planning, it is the most widely used and most effective technique used theoretically and practically. Figure 2.5 shows the cell boundary of sites in Sub-urban area of the city. Figure 2.6 shows the cell boundary in the open area of the city. Figure 2.7 illustrates the signal strength in the urban area of the city. Because of the dense population the signal power is strong throughout to ensure high quality calls to the subscribers with minimum interference and call drop. Figure 2.8 shows the 2G signal strength in the Sub-urban areas where population density is low and so the power required is less as compared to urban areas. Figure 2.9 shows the serving signal strength in open area. The signal is the weakest as there is the least number of people in open area. CHAPTER 3 FUNDAMENTALS OF 3G 3.1 INTRODUCTION The Universal Mobile Telephony System (UMTS) or 3G as it is known is the next big thing in the world of mobile telecommunications. It provides convergence between mobile telephony broadband access and Internet Protocol (IP) backbones. This introduces very variable data rates on the air interface, as well as the independence of the radio access infrastructure and the service platform. For users this makes available a wide spectrum of circuit-switched or packet data services through the newly developed high bit rate radio technology named Wideband Code Division Multiple Access (WCDMA). The variable bit rate and variety of traffic on the air interface have presented completely new possibilities for both operators and users, but also new challenges to network planning and optimization. The success of the technology lies in optimum utilization of resources by efficient planning of the network for maximum coverage, capacity and quality of service. This part of our project aims to detail method of UMTS Radio Network (UTRAN) Planning. The new technologies and services have brought vast changes within the network planning; the planning of a 3G network is now a complex balancing act between all the variables in order to achieve the optimal coverage, capacity and Quality of Service simultaneously. 3.2 WCDMA In UMTS access scheme is DS-CDMA (Direct Sequence CDMA) which involves that a code sequence is directly used to modulate the transmitted radio signal with information which is spreaded over approximately 5 MHz bandwidth and data rate up to 2 Mbps. Every user is assigned a separate code/s depending upon the transaction, thus separation is not based on frequency or time but on the basis of codes. The major advantage of using WCDMA is that there is no plan for frequency re-use. 3.3 NODE B Node B functions as a RBS (Radio Base Station) and provides radio coverage to a geographical area, by providing physical radio link between the UE (User Equipment) and the network. Node B also refer the codes that are important to identify channels in a WCDMA system. It contains the RF transceiver, combiner, network interface and system controller, timing card, channel card and backplane. The Main Functions of Node B are: Closed loop power control CDMA Physical Channel coding Modulation /Demodulation Micro Diversity Air interface Transmission /Reception Error handling Both FDD and TDD modes are supported by Single node B and it can be co-located with a GSM BTS to reduce implementation costs. The conversion of data from the Radio interface is the main task of Node B. It measures strength and quality of the connection. The Node B participates in power control and is also responsible for the FDD softer handover. On the basis of coverage, capacity and antenna arrangement Node B can be categorizes as Omni directional and Sectorial: OTSR (Omni Transmitter Sector Receiver) STSR (Sector Transmitter Sector Receiver) 3.3.1 OTSR (Omni Transmit Sector Receive) The OTSR configuration uses a single (PA) Power Amplifier, whose output is fed to a transmit splitter. The power of the RF signal is divided by three and fed to the duplexers of the three sectors, which are connected to sectorized antennas. 3.3.2 STSR (Sectorial Transmit Sector Receive) The STSR configuration uses three (PA) Power Amplifier, whose output is fed directly to the duplexers of the three sectors, which are connected to sectorized antennas. Node B serve the cells which depend on sectoring. 3.4 ACCESS MODES 3.4.1 FDD (Frequency Division Duplex) A duplex method whereby uplink and downlink transmissions use two separated radio frequencies. In the FDD, each downlink and uplink uses the different frequency band. 3.4.2 TDD (Time Division Duplex) It is a method in which same frequency is used for the transmission of downlink and uplink by using synchronized time intervals. Time slots are divided into transmission and reception part in the physical channel. 3.4.3 Frequency Bands 3.4 CELLULAR CONCEPT The UMTS network is third generation of cellular radio network which operate on the principle of dividing the coverage area into zones or cells (node B in this case), each of which has its own set of resources or transceivers (transmitters /receivers) to provide communication channels, which can be accessed by the users of the network. A cell is created by transmitting numerous number of low power transmitters. Cell size is determined by the different power levels according to the subscriber demand and density within a specific region. Cells can be added to accommodate growth. Communication in a cellular network is full duplex, which is attained by sending and receiving messages on two different frequencies. In order to increase the frequency reuse capability to promote spectrum efficiency of a system, it is desirable to reuse the same channel set in two cells which are close to each other as possible, however this increases the probability of co-channel interference . The performance of cellular mobile radio is affected by co channel interference. Co-channel interference, when not minimized, decreases the ratio of carrier to interference powers (C/I) at the periphery of cells, causing diminished system capacity, more frequent handoffs, and dropped calls. Usually cells are represented by a hexagonal cell structure, to demonstrate the concept, however, in practice the shape of cell is determined by the local topography. 3.4.1 Types of Cell The 3G network is divided on the basis of size of area covered. Micro cell the area of intermediate coverage, e.g., middle of a city. Pico cell the area of smallest coverage, e.g., a hot spot in airport or hotel. Macro cell the area of largest coverage, e.g., an complete city. 3.5 FADING Fading is another major constraint in wireless communication. All signals regardless of the medium used, lose strength this is known as attenuation/fading. There are three types of fading: Pathloss Shadowing Rayleigh Fading 3.5.1 Pathloss Pathloss occurs as the power of the signal steadily decreases over distance from the transmitter. 3.5.2 Shadowing Shadowing or Log normal Fading is causes by the presence of building, hills or even tree foilage. 3.5.3 Rayleigh Fading Rayleigh Fading or multipath fading is a sudden decrease in signal strength as a result of interference between direct and reflected signal reaching the mobile station. 3.6 HANDOVER IN CDMA The term handover or handoff refers to the process of transferring data session or an ongoing call from channel to channel connected to the core network to another. The handover is performed due to the mobility of a user that can be served in another cell more efficiently. Handover is necessary to support mobility of users. Handover are of following types (also known as handoff): Hard Handover Soft Handover Softer Handover 3.6.1Hard.Handover In Hard handover the old radio links in the UE are dispose of before the new radio links takes place. It can be either seamless or non-seamless. In seamless hard handover, the handover is not detected by the user. A handover that needs a change of the carrier frequency is a hard handover. 3.6.2Soft.Handover Soft handover takes place when cells on the same frequency are changed. Atleast one radio link is always kept to the UTRAN in the removal and addition of the radio links. It is opperated by means of macro diversity in which many radio links are active. 3.6.3Softer.handover It is one of the important case of soft handover which describe the removal and addition of the radio links which is being belonged by the same Node B. Macro diversity can be performed in the NODE B with maximum ratio combining in softer handover. There are inter-cell and intra-cell handover. Handover 3G 2G (e.g. handover to GSM) FDD inter-frequency hard handover TDD/FDD handover (change of cell) TDD/TDD handover FDD/TDD handover (chan

The Scandinavian Influence On The English Language English Language Essay

The Scandinavian Influence On The English Language English Language Essay The Viking colonisation of the British Isles had a considerable effect on the English language and vocabulary. Even today, after hundreds of years, we can still see the evidence of Scandinavian influence. This paper deals with the influence of Scandinavian on the English language. The aim of this paper is to show examples and explain the impact of Scandinavian on the English language. 1. Introduction The history of English language is usually divided up into four major periods that can be justified both on the basis of linguistic differences and on the basis of historical events that influenced the later development of English language  [1]  . These periods are Old English (450-1150), Middle English (1150-1500), Early Modern English (1500-1700) and Modern English (1700-present). These years are not strict boundaries but rough approximations. English has been influenced by many languages and one of them is Scandinavian (in the period of OE and ME). Scandinavian loans differ from other loans from the same period because they refer to common, everyday events and objects. Because of its extent, it is one of the most interesting of the foreign influences on the English language. 2. The Scandinavian influence on the English language Their activities began in plunder and ended in conquest. (Baugh and Cable 92) 2.1. Historical background The Viking Age lasted roughly from the middle of the eighth century to the beginning of the eleventh. The Vikings were the Germanic tribes of the Scandinavian Peninsula and Denmark. The reasons for their sudden attacks and voyages are unknown; it is possible that they were of economic or political nature. In their adventures the Swedes established a kingdom in Russia; Norwegians colonized parts of the British Isles, the Faroes, and Iceland, and from there pushed on to Greenland and the coasts of Labrador and Newfoundland; the Danes founded the dukedom of Normandy and finally conquered England (Baugh 92). Vikings conquered large areas of England but were stopped by King Alfred of Wessex. He signed the Treaty of Wedmore (878) with Gunthrum, the Viking leader. The treaty defined the boundary line, running roughly from Chester to London, to the east of which the Vikings were to remain (Berndt 1989: 22). This area was where Danish law and customs were followed and would later be known as the Danelaw. In the beginning of the eleventh century, the Vikings reached the pinnacle of their achievement Cnut, king of Denmark, conquered Norway England and obtained the throne of England (Berndt 23). Viking invasions led to an immigration wave from Scandinavia. Although most of the new inhabitants were Danes, there were also Norwegians and Swedes. The two peoples, the English and the Scandinavian, amalgamated. As is described in Baugh and Cable (98), the Scandinavians intermarried with the English, adopted many of their customs and accepted Christianity. Not much is known about the relation of the two languages. In some places the Scandinavian gave up their language early and in some places Norse was spoken as late as the seventeenth century. It is also highly possible that some of the new inhabitants were bilingual. Old Norse and Old English were similar languages so it is highly probable that the two may even have been mutually intelligible to a limited extent (Baugh and Cable 96) which made the process of borrowing and adoption easier. 2.2. Scandinavian place-names Many places in today England bear Scandinavian names (more than 1,400). These names are notable evidence that the Vikings once settled in England. These places are mostly situated in the district of the Danelaw but are not uniformly distributed (Berndt 22, 64). According to Baugh and Cable (98-99), there are more than 600 places with names ending in -by (such as Whitby, Grimsby). The Scandinavian word by means farm or town; the word can also be seen in by-law (town law). Some 300 place-names end in the Scandinavian word thorp that means village (like Althorp, Bishopsthorpe, Linthorpe). There are almost as much place-names that contain the word thwaite, an isolated piece of land (e.g. Applethwaite, Langthwaite). Around a hundred end in toft, a piece of ground, a messuage (Brimtoft, Nortoft). Even personal names bear witness to the Scandinavian influence. Names with the suffix -son like Stevenson or Johnson are the Scandinavian equivalent of OE patronymic -ing (as in Browning). 2.3. The tests of borrowed words As previously stated, Old English and Old Norse were similar languages; some common words of the two languages were even identical. Therefore, in some cases, it is difficult to determine whether a word in Modern English is native or a borrowed word. However, there are some reliable criteria that help to determine the origin of the word. Baugh and Cable (96-97) enumerate and exemplify three criteria. One of the simplest is (1) the development of the sound sk. In OE, this sound was palatalized to sh (written sc), except in the combination scr while in ON it retained its hard sk sound. So, for example, native words like ship and fish have sh in Modern English, whereas words borrowed from Scandinavian are still pronounced with sk: sky, skin, skill, scrape, whisk. An interesting example is that of the OE word scyrte that became skirt in Modern English, whereas the corresponding ON form skyrta became skirt. The retention of the hard pronunciation of k and g in words such as kid, get, give, and egg indicates Scandinavian origin. Occasionally, (2) the vowel of a word helps to determine the origin. For example, the Germanic diphthong ai became Ä  in OE (Ã…Â  in Modern English) and in ON it became ei or Äâ€Å". Some examples of borrowed words are aye, nay, hale, reindeer and swain. These kinds of tests, based on sound-developments in the two languages, are the most reliable means of distinguishing Scandinavian from native words. Sometimes (3) meaning can help to determine the origin of the word. The Modern English word bloom (flower) could have come from OE blÃ…Â ma or Scandinavian blÃ…Â m. The OE word meant an ingot of iron, whereas the Scandinavian word meant flower, bloom. The ON meaning is the one in ordinary use while the OE word has survived as a term in metallurgy. Another example where meaning helps us to determine the origin of the word is the word gift. In OE this word meant the price of a wife, and thus marriage in the plural, where as the ON word had a more general sense with the meaning of gift, present. 2.4. Scandinavian loanwords Although the Scandinavian loan words began to enter the English language probably at the same time when the Vikings settled down (the period of Old English), the evidence in writing can be found mostly in Middle English texts. The loanwords were recorded long after they came in use because it took some time before they entered the standard English. Baugh and Cable divided the early loanwords (in OE) into two groups. The first group constitute words associated with sea-roving and predatory people (99). The second group is made out of words relating to the law or characteristic of the social and administrative system of Danelaw (99). After the Norman Conquest, most of the words from the second group were replaced by the French terms and thus can no longer be found in Modern English. It was only after the Danes had begun to settle down that Scandinavian words started to enter in greater numbers into language. We cannot divide these words into different domains of thought or experience because Scandinavian loanwords are varied and simple (as opposed to the French or Latin loanwords). They include common, familiar, everyday words. The following list serves only illustrative purposes and is not in any way exhaustive, as there are around 900 Scandinavian words in Modern English. NOUNS axle-tree band bank birth boon booth brink bull calf (of leg) crook dirt down (feathers) dregs egg fellow freckle gait gap girth guess hap husband keel kid law leg link loan mire race reef (of sail) reindeer rift root scab scales score scrap seat sister skill skin skirt sky slaughter snare stack steak swain thrift tidings trust want window ADJECTIVES awkward flat ill loose low meek muggy odd rotten rugged scant seemly sly tattered tight weak VERBS bait bask batten cal cast clip cow crave crawl die droop egg (on) flit gape gasp get give glitter hit kindle lift lug nag raise rake ran-sack rid rive scare scout (an idea) scowl screech snub sprint take thrive thrust As already mentioned, these words are very common and of everyday use. There probably existed words for the same concepts in OE, so the new words could have supplied no real need in the English vocabulary. However, these words made their way into the English as the result of the mixture of two peoples. Scandinavian loanwords are very interesting because they refer to ordinary things and because they retained in the language. As Ruiz Moneva (184) points out, the most important source languages at OE and ME period were Celtic, Latin, French and Scandinavian. But, contrarily to what had happened with the Celts, the Scandinavian influence upon the English language is characterized by its intensity, the great and important areas of the language which were affected (Ruiz Moneva 184). As previously stated, at one time, both languages were used side by side. This situation could have resulted in six different scenarios (Baugh and Cable 99-102; Ruiz Moneva 187-88). (1) If words in the two languages coincided more or less in form and meaning, the modern word stands at the same time for both its English and its Scandinavian ancestors. Some examples are burn, cole, drag, fast, hang, murk(y), scrape, thick. (2) If there were differences in form, the English word often survived. Some examples are bench, goat, heathen, yarn, few, grey, loath, leap, flay. Corresponding Scandinavian forms can often be found in ME literature and in some cases they still exist in dialectal use (e.g. screde, skelle, skere with the hard pronunciation of the initial consonant group; the standard English forms are shred, shell, sheer). (3) In some cases, the Scandinavian word replaced the native word, often after two had long remained in use concurrently. For example, the word awe is of Scandinav ian origin and its cognate eye (aye) was an OE word. In the earlier part of the ME period the English word was more common, but later on (by 1300) the Scandinavian form appeared more often and finally replaced the Old English word. The same happened with the words for egg ey (English) and egg (Scandinavian); words for sister OE sweostor, ON syster; the ON verb take replaced the OE niman. (4) Sometimes, both the English and Scandinavian words survived with a difference of meaning or use (the English word is given first): no-nay, whole-hale, rear-raise, from-fro, craft-skill, hide-skin, sick-ill. (5) Some native words that were not in common use were reinforced or reintroduced from the Scandinavian. Examples are till, dale, rim, blend, run and the Scottish bairn. (6) Finally, the English word might have been modified by taking on some characteristics of the corresponding Scandinavian word. Examples include give and get with their hard g and Thursday instead of the OE ThunresdÃ…â €Å"g. 2.5. Form (grammatical) words Scandinavian words that made their way into English were not only open class words (nouns, adjectives and verbs). The Scandinavian influence extended to grammatical words pronouns, prepositions, adverbs, and even a part of the verb to be. This is not a common case when it comes to borrowing. The pronouns they, their, them are Scandinavian (OE were hÄ «e, hiera, him). Both and same, although they are not pronouns, have pronominal uses and are of Scandinavian origin. Some other examples include the conjunction though, adverbs aloft, athwart, aye (ever) and seemly. One of the most important Scandinavian words in English is the present plural of the verb to be are. The Scandinavian form took place of bÄâ€Å"oth or sind. 2.6. Syntax and grammar Scholars do not agree on the Scandinavian influence on the English syntax. Baugh and Cable (103-105) claim that the Scandinavian influence not only affected the vocabulary but also extended to [] syntax. They admit that it is less capable of exact demonstration, but then conclude that it is hardly to be doubted (103). Kirch (503), on the other hand, argues that all of the previous claims made about the influence of Scandinavian on English syntax are the subject of much controversy. It was considered that these syntactic features originated from Scandinavian: (1) relative clauses without pronouns, (2) the omission of the conjunction that, (3) the use of shall and will in Middle English, (4) the genitive before nouns (Kirch 503). But Kirch (503-510) refutes the quoted features and concludes that the investigation turns up no positive proof of Scandinavian influence on English syntax (510). Berndt does not even mention syntax, so it is possible that he considers that Scandinavian did in fluence it. 3. Conclusion As we have seen, even today, after so many years, we can still see the evidence of Scandinavian influence in English. There are thousands of place-names of Scandinavian origin. Many common and everyday words have Scandinavian origin. We cannot even imagine the English vocabulary without them. What is even more fascinating is that Scandinavian left an imprint on grammatical words and possibly syntax, which is a rare case when it comes to borrowing. It can be concluded that Scandinavian has had significant impact on the development of the English vocabulary.

Comparing Jane Smileys A Thousand Acres and William Shakespeares King

Comparing Jane Smiley's A Thousand Acres and William Shakespeare's King Lear Jane Smiley's novel A Thousand Acres is a modern version of William Shakespeare's King Lear.   The tragic ideas brought out by King Lear are revisited in A Thousand Acres both containing universal themes in which societies from past to present can identify with.   Tragedy is a form of drama that depicts the suffering of a heroic individual who is often overcome by the very obstacles he is struggling to remove.   The novel and play each contain distinct tragic elements that lead to the development of similar characters, plot, and images but both have distinct themes.   A Thousand Acres provides a new interpretation of Shakespeare's classic tragedy allowing the reader to create a unique twist to their opinions of the Lear family. William Shakespeare's tragedy of King Lear begins with the King's decision to divide his kingdom between his three daughters.   He gathers them all together, and tells them he will divide up the kingdom according to whoever has the most love for him.   Goneril and Reagan, the two older daughters, make big declarations of love in order to get the shares they want of the kingdom.   The youngest daughter, Cordelia, tells Lear that she loves him, as a daughter should love a father.   Lear becomes angry and disappointed with Cordelia's response feeling she has shown a lack of devotion so he takes action and banishes her.   When Kent, a close friend of Lear, attempts to defend Cordelia, but as well he is banished by Lear.   Cordelia marries the King of France and goes to live there. The kingdom is equally divided between Goneril and Regan.   These two daughters are evil and decide if Lear becomes too much of a problem then they will take d... ... which would have prevented this tragedy.   The blinding Gloucester becomes ironic because when he is blinded he is able to see that he has judged his son Edgar wrongly and it is Edmund who is evil.   Similarly, in A Thousand Acres   Loren the loyal son is the cause of his tragedy.  Ã‚   Both Lear and Larry become mad after giving up their power too early.   When Lear turns his kingdom over to his daughters he looses respect and power which cause him to go mad.   When Larry signs his farm over to his daughters he looses control of the land and goes mad.   Works Cited and Consulted Bradley, A.C.
