Human Desire To Fit In Essays - Human Behavior, Belief, Autonomy

Human Desire to Fit In Two common ways of handling a situation are either to do so according to one?s own personal needs and desires with no specific regard to other people, or one can base a decision on how it will be viewed by others. The vast majority of people fall on the side of being worried about what others are saying and thinking. Both good and bad can come from living this way, but it has seemed to remain constant throughout history. People have a natural desire to belong, and to fit in with a certain group. No matter what group an individual chooses, that individual almost always is forced sacrifice a part of them self in order to seem more a part of things. People in this world seem to need companionship and are often too weak to stand alone. As a result, they stand together in what ever group they are best suited to. It is a point of interest to many of the people who have stopped to think about this fact. The idea that people live according to how others will perceive then has been established as the rule, not the exception. The real question now lies in the reasons for this way of life. It was hypothesized by C.S. Lewis that this desire to belong and to fit in is a natural human characteristic. He believed that people have an instinctive drive to belong, in the same sort of way species reproduce. It is possible that his theory of instinctive necessity is accurate, and humans are as a whole are week and scared when they are faced with solitude. The old adage ?there is safety in numbers? is appropriate in this topic. Often in this world terrible things happen because people group up and commit unspeakable acts, then take shelter in the numbers of those involved. The Annual Freaknik ?celebration? is the perfect example. Thousands of individuals crowd the streets of Atlanta and pillage the city for a weekend, all the while they show no respect for the laws or the residents of the city. This can be directly related to the issue of people doing things to be a part of the group. If these people were asked individually why they did these terrible things, for the most part they would respond by saying ?everyone else is doing it. This could be translated to ?I am just trying to be a part of things?. In this particular example those involved sacrifice any sense of morals or upbringing that they might have had. ?Everybody is doing it?. This sentence has ruined thousands of lives. It could could be the worst four word combination in the English language. People have been convinced to begin drug use, drunk driving, cliff jumping, and countless other unwise activities. The reason behind this is clear, the human necessity to fit in and to seem cool is often to strong to compete with. A person could have the world and all of its riches, but with out someone to share it with, that person would be totally alone. People need each other. This is a fact of the world, and it will never change. This need is a natural desire that is found every where in every person with very few exceptions. It is true that trouble can brew and awful things can happen because of these groups, but the advantages associated far out weigh the costs. These groups that people form between themselves often serve as shelter for the lonely, for this reason it is natural for people to go far out their way if necessary to belong a particular crowd. As a result the opinion of others is crucial part of life. and fuck you you are a bunch of profiteering whores and should be bludgoned to death with a wet noodle! thank you and go to hell....pigfucker!!!

The Purpose of the Crusades from 1096 AD to 1270 AD Essay Essay Example

The Purpose of the Crusades from 1096 AD to 1270 AD Essay Essay Example The Purpose of the Crusades from 1096 AD to 1270 AD Essay Paper The Purpose of the Crusades from 1096 AD to 1270 AD Essay Paper The Crusades are considered as an built-in portion of World History. They were important events for Islam and Christendom likewise. What are the Crusades all about? Why did they happen? What was its intent? This research paper aims to discourse the definition. beginning and most significantly. the intent of the Crusades. Definition of Campaign The Crusades are military jaunts with a spiritual aim. as these are sanctioned by the Pope and the Church ( Sloan. 2000 ; â€Å"Crusades–Battles. † 2008 ) . Originally. the word â€Å"Crusade† meant all missions accomplished on the promise of salvaging the Christian districts from Muslim business ( Brehier. 1908 ) . However. during the mediaeval times. the word had acquired a cover definition. as it came to include all wars against enemies of Christendom ( Brehier. 1908 ) . All the Crusades occurred between the eleventh and the 13th centuries A. D. ( â€Å"Crusades–Battles. † 2008 ) . Harmonizing to Sloan ( 2000 ) . the term â€Å"crusade† was derived from the Portuguese wordcruzado. which means â€Å"mark with a cross. † Other beginnings. on the other manus. province that the word meant â€Å"cloth cross† ( Brehier. 1908 ; â€Å"Crusades-Battles. † 2008 ) . As the definition implies. the symbol for the Crusades was the Christian cross ( â€Å"Crusades–Battles. † 2008 ) . and it was secured on the garment worn by the Crusaders ( Brehier. 1908 ; Sloan. 2000 ) . Beginning of Crusades The Crusades were the consequence of a metempsychosis of spiritual ardor in 10th century Europe ( Sloan. 2000 ) . However. this was non the lone ground. as the people who were involved with the Campaigns joined because of personal involvements every bit good ( Sloan. 2000 ) . The Crusades were besides called â€Å"holy wars. † as they provided a locale for the pontificate to pay a legitimate war against the enemies of Christianity ( Sloan. 2000 ) . The Crusades besides gave the spiritual an chance to obtain redemption by agencies of pilgrims journey ( Sloan. 2000 ) . Four centuries prior. similar pilgrims journeies have occurred because of the ongoing feud between the Muslims and the Christians ( Sloan. 2000 ) . The finishs of the said pilgrims journeies include the countries where both faiths meet. illustrations of which are Sicily. Italy. Asia Minor and Spain ( Sloan. 2000 ) . Jerusalem is another pilgrim finish ( Sloan. 2000 ) . In a manner. the Crusades were highly helpful to the pontificate. and it is non merely because of the Pope’s aim of taking back lands from the custodies of Muslims. The Crusades besides served to interpret the combatant inclinations of the Christians into a productive enterprise ( Sloan. 2000 ) . The Crusades enjoyed popularity and intense support from the Christians merely because they were a manifestation of a Godhead licence to contend other work forces in the name of redemption ( Sloan. 2000 ) . Meanwhile. the attempts of the Crusaders helped the Church spread the influence of Christianity all over the universe ( Sloan. 2000 ) . The Crusades began in the 11th century. and stemmed from the bing issues of morality and political relations of Western Christendom ( Brehier. 1908 ) . The twelvemonth 1095 marked the thirtieth day of remembrance of William the Conqueror’s success in the fusion of England ( â€Å"The Church and the Crusaders. † 2007 ) . However. the Gallic had delegated the districts to certain relations. spliting it in the procedure ( â€Å"The Church and the Crusaders. † 2007 ) . It was these districts that caused feud between brothers. which subsequently resulted in warfare ( â€Å"The Church and the Crusaders. † 2007 ) . That is why during that period. Europe consisted of many provinces which were ruled by sovereign ( Brehier. 1908 ) . These sovereigns were excessively preoccupied with territorial struggles while the emperor. who governed over Christendom. was engrossed with coronation jobs ( Brehier. 1908 ) . Merely the Catholic Pope had a considerable capacity to unite the provinces ; hence. merely the pontificate could originate such an ambitious enterprise like the Crusades ( Brehier. 1908 ) . The governments did recognize that Europe was really much susceptible to menaces from the Byzantine Empire and the Muslims ( Brehier. 1908 ) . However. the Catholic Pope could non easy convince people to take part in a bold journey like the Crusades for the ground of the mere chase of Jerusalem ( Brehier. 1908 ) . Fortunately for the Catholic Pope. the pressing issues with Syria were plenty to actuate Christians to ship on the Crusades. and Pope Urban II did non hold much trouble looking for participants ( Brehier. 1908 ) . The latter portion of the 5th century saw the uninterrupted exposure to the East. Cities such as Gaul and Italy were visited by Syrians who brought with them Eastern humanistic disciplines. civilization and faith ( Brehier. 1908 ) . In add-on. Western Christians have travelled to topographic points such as Syria. Palestine and Egypt. largely because they wanted to travel to Jerusalem. There were so many pilgrims journeies to the East. and even onslaughts by savages did non decrease the Numberss. As a response to the demands of the legion pilgrims journeies. St. Gregory the Great built a hospice for the pilgrims in Jerusalem in 600 AD ( Brehier. 1908 ) . The early portion of the 8th century saw the troubles the Anglo-saxons had to confront merely to make the Holy Land ( Brehier. 1908 ) . An illustration of such adversity which was the instance of St. Willibald. Bishop of Eichstadt. whose pilgrims journey lasted seven long old ages ( Brehier. 1908 ) . Following their victory in the West. the Carolingians sought to better the province of the Latin citizens situated in the Eastern district ( Brehier. 1908 ) . This determination resulted in the understanding between Pepin the Short and Caliph of Bagdad ( Brehier. 1908 ) . Through the representatives from Haroun al-Rashid. the â€Å"keys to the Holy Sepulchre. the streamer from Jerusalem and some cherished relics† were given to the King of Franks ( Brehier. 1908. parity. 6 ) on November 30. 800. This gesture was symbolic. as it came to mean the â€Å"Frankish associated state over the Christians of Jerusalem† ( Brehier. 1908. parity. 6 ) . Seventy old ages after. Bernard the Monk went on a journey to Jerusalem. and found that the agreement was still upheld. There was prosperity and growing for the constitutions. a testament to the regular sending of alms to Jerusalem from the West ( Brehier. 1908 ) . However. things began to alter by the 10th century. Europe was confronting a sociopolitical crisis. and the pilgrims journeies were all of a sudden disrupted by Muslims ( Brehier. 1908 ) . The Muslims. under the leading of Caliph Omar. have occupied Jerusalem in 637 AD ( â€Å"The Crusaders. † n. d. ) . Since so. Jerusalem had been under Muslim control. Despite this. spiritual tolerance between the two religions existed ( â€Å"The Crusaders. † n. d. ) . The Muslims gave the pilgrims permission to travel about with their spiritual enterprises. granted that they were to pay for them to be allowed entree ( â€Å"The Crusaders. † n. d. ) . On the other manus. they prohibited the building of new churches and the exhibition of crosses outside church premises ( â€Å"The Crusaders. † n. d. ) . The civil relation between Islam and Christianity was sustained for 400 old ages ( â€Å"The Crusaders. † n. d. ) . until the torment occurred ( Sloan. 2000 ) . It was found that Muslims were hassling those that visited the Holy Land. which made the trips to Jerusalem about intolerable. The state of affairs got worse. as the Fatimite Caliph of Egypt named Hakem demanded that all Christian establishments destroyed in 1009. including the Holy Sepulchre. ( Brehier. 1908 ) . The wake of this event resulted in widespread Christian subjugation ( Brehier. 1908 ) . The twelvemonth 1027 saw the overthrow of the Frankish associated state. which was later replaced by the Byzantine emperors ( Brehier. 1908 ) . As a people. the Muslims were non conditioned to be ever at war ; it is their faith that is responsible for their combatant dispositions ( Madden. 2002 ) . This is because Islam had ever been rooted in war ( Madden. 2002 ) . Even during Mohammed’s epoch. Islam had to fall back to warfare to distribute its beliefs ( Madden. 2002 ) . Islamic thought had long upheld a duality of the universe through the two residences. the Abode of Islam and the Abode of War ( Madden. 2002 ) . Both residences were for Muslims merely. go forthing no room for any other faith. However. tolerance is still possible. but merely within the parametric quantities established by Islam ( Madden. 2002 ) . This tolerance. on the other manus. was non an original facet of Islam. Harmonizing to Islamic beliefs. the belongingss and districts of other faiths. such as Christianity and Judaism. should be eradicated and seized ( Madden. 2002 ) . This belief likely originated during the 7th century. the clip when Mohammed was contending against Mecca ( Madden. 2002 ) . Back so. Christianity was highly influential and had legion districts to its name. doing it susceptible to Muslim onslaughts ( Madden. 2002 ) . After Mohammed died. the Muslims devoted their lives to the conflict against Christianity ( Madden. 2002 ) . They did so win in this enterprise ; one by one. Christian districts fell in the custodies of the Muslims. Jerusalem included. Despite the Muslim bullying. pilgrims continued to continue to Jerusalem in the 11th century. If earlier pilgrims journeies consisted of members of the wealthier category. this clip even in-between category citizens participated in the pilgrims journeies ( Brehier. 1908 ) . The figure of pilgrims increased ; Richard. Abbot of Saint-Vannes. brought 700 pilgrims with him in 1026. while Gunther. Bishop of Bamberg. led 12. 000 Germans to the Holy Land ( Brehier. 1908 ) . It was Gunther’s group that had to support themselves from Bedouins. turn outing that the faithful were excessively devoted to the Holy Sepulchre to withdraw ( Brehier. 1908 ) . This is a testament to the dedication of the pilgrims. that even though they knew the danger inherent in the trip. they still proceeded. They would volitionally put on the line their lives for this spiritual enterprise. However. it was the Seljukian Turks who became the biggest menace to the pilgrims. the Byzantine Empire and Christendom as a whole ( Brehier. 1908 ) . One by one. districts were sacked and captured by the Turks: Jerusalem was the first to be captured. rapidly followed by Asia Minor. Syria and Antioch ( Brehier. 1908 ) . Soon. all the districts were under Turkish control. The offenses committed by the Turks against the Christians were plenty: shrines were desecrated. pilgrims were either beat up. kidnapped or killed. while relics and other belongingss were stolen. This state of affairs prompted the Constantinople emperors to inquire the Catholic Popes for aid. which resulted in communicating between Michael VII and Gregory VII ( Brehier. 1908 ) . The Purpose of Crusades Because of the Seljukian Turks’ onslaught towards Byzantine Empire and Christendom. the thought of the Crusades emerged. The initial thought consisted of the Catholic Pope directing out military personnels to the East with three aims in head: â€Å"to re-establish Christian integrity. repel the Turks. and rescue the Holy Sepulchre† ( Brehier. 1908. parity. 8 ) . Unfortunately. this program was non put into action ; there were several factors that served as hinderances. To get down with. the Investitures had the Catholic Pope preoccupied ( Brehier. 1908 ) . Besides. emperors Nicephorus Botaniates and Alexius Comnenus both disapproved of a Roman spiritual brotherhood. Last. the war that had all of a sudden erupted between the Normans of the Sicilies and the Byzantine Empire was another factor ( Brehier. 1908 ) . The Birth of the Campaign However. the Crusades still came into fruition. this clip under the authorization of Pope Urban II ( Brehier. 1908 ) . In fact. many historiographers consider the construct of the Crusades as Pope Urban II’s inspiration ( Brehier. 1908 ) . In the twelvemonth 1095. Pope Urban II had a conference in Clermont. France ( â€Å"The Crusaders. † n. d. ) . After eight yearss. the Catholic Pope delivered a address to the crowd. in which he declared his desire to salvage Jerusalem from the custodies of the Muslims ( â€Å"The Crusaders. † n. d. ) . Pope Urban II besides said that all those who would take part would hold unsusceptibility from the wickednesss that will be committed in the Crusades ( â€Å"The Crusaders. † n. d. ) . The crowd responded good to the pope’s call. and answered him with the statement: â€Å"It is the will of God† ( â€Å"The Crusaders. † n. d. . parity. 2 ) . The Unofficial Crusade under Peter the Hermit However. it was Peter the Hermit who started the Crusades. From Picardy. he had traveled to Jerusalem and saw the Holy Sepulchre for himself ( Brehier. 1908 ) . It was this visit that encouraged Peter the Hermit to near the Catholic Pope about his purposes about the Crusade. In bend. Pope Urban II gave Peter the Hermit his approval ( Brehier. 1908 ) . Hence. it was Peter the Hermit who led the first campaign. despite its unofficial position ( â€Å"The Crusades Begin. † n. d. ) . The campaign of Peter the Hermit began in 1095. in which he gave discourses to provincials to promote them to take part in the campaigns ( â€Å"The Crusades Begin. † 2007 ) . As a consequence. he had gathered a little group of people who would travel to Jerusalem ( â€Å"The Crusades Begin. † 2007 ) . It was Peter the Hermit’s ardor for prophesying that worked to his advantage. It was this quality that converted provincials into reformers. people who embraced his instructions so much that he was considered as a saint ( â€Å"The Crusades Begin. † 2007 ) . Regardless of his part to the Crusades. the bookmans have downplayed his portion. doing him look less of import than how he was earlier portrayed by the likes of Albert of Aix and William of Tyre ( Brehier. 1908 ) . Unfortunately. the campaign of Peter the Hermit was unsuccessful. The reformers exhibited disorderly behavior while going ; they stole nutrient and supplies from the people’s places ( â€Å"The Crusades Begin. † 2007 ) . In add-on. they killed Hebrews while they were still in the European district ( â€Å"The Crusades Begin. † 2007 ) . The first functionary Crusade had one simple aim: the retrieval of Jerusalem from Muslim control ( â€Å"The First Crusade. † 2008 ) . In a military position. this was the most winning among all the other Crusades ( United Methodist Women. n. d. ) . The first Crusade invaded the Holy Land. an onslaught that lasted for five hebdomads ( Metropolitan Museum of Art [ MET ] . 2007 ) . In 1099. Christianity had gained Jerusalem back ( MET. 2007 ) . The Second Crusade occurred between 1147 and 1149. and was led by Abbot Bernard of Clairvaux ( MET. 2007 ) . This was non every bit successful as the first 1. because the Muslim forces had regained their strength ( MET. 2007 ) . By October 1187. under the leading of Salah al-Din. the Muslim military personnels recaptured the Holy Land ( MET. 2007 ) . The Third Crusade was successful. insofar as it recaptured Cyprus and Acre metropolis ( MET. 2007 ) . The most destructive Campaign. non to advert the most dissatisfactory for the Church was the Fourth Crusade ( MET. 2007 ) . The Crusaders deviated from the original program. and attacked Constantinople alternatively ( MET. 2007 ) . There were three more Campaigns after. In decision. the Crusades were rooted in the defence against Muslim aggression. The chief intent of the Crusades was to repossess control over the Holy Land. and unite Christendom one time once more. The Crusades are so a important portion of history. as it plays a cardinal function in the development and growing of Islam and Christianity. Regardless of one’s faith. these events must be considered so that the errors committed in the past must non be repeated. In the terminal. the difference in faith must be celebrated and respected.

James Burkes - Essay Example Consequently a lot of materials got lost with no one being aware. By the end of the 14th century there was a boom for everything that could be sold, everyone who had something to sell went to sell and this was the beginning of goods and money being exchanged. Towns and businesses developed giving a meaning to paperwork and a need to keep records. As business grew, demand for documentation also grew and the number of writers increased. In 1439 metal bars with engraved letters for faster printing were invented; they would be arranged in a paper frame, smeared with ink allowing printing of as many similar pages as it could get. Arrangement would be changed to make different page contents. This ensured access to Church Bibles, pamphlets and other documents. Rebellion started through pamphlets when Luther printed fourteen complaints to the Church, one being that forgiveness pamphlets were not supposed to be sold. This gave people a chance to express their disagreements. Books in different fields were printed and fashion spread worldwide, with printed science materials scientists were able to correct mistakes. Book fairs were held all over Europe boosting everyone’s sense of identity. Emergence of libraries triggered indexing and cross indexing that would show relations in content, thus, leading to more knowledge discovery. In 1939 the computer was invented; it has led to numerous growths in the field of science and technology. Before the 16th century, the church controlled everything and anything in the Bible was not questioned. Copernicus, who was a priest, researched on heavenly arrangements contradicting views that the Earth was the center of the universe; he discovered that the sun was at the center of the universe. After his discovery he published manuscripts saying that the Earth moves and the sun was at the center of the universe but no one believed him. More researches were done proving that circular motion becomes

Knowledge of the Main Changes that Go With the Divorce Research Paper

Knowledge of the Main Changes that Go With the Divorce - Research Paper Example Ross (1972) argued that parental discernments are a product of both the child's behaviour and the parent's acceptance level. It appears credible that depression influences individual differences between parents in their acceptance for a variety of child behaviours. Clinical symptoms that co-vary with depression, such as distractibility and restlessness, may increase the possibility that single mothers will selectively attend to moderately low-frequency inapt behaviour, forming impressions of her children's alteration that are not acceptable by objective counts of behaviour. Alternately, parental depression and distress may raise attention to moderately high-frequency rebellious behaviours that were not interpreted as worrisome prior to the inception of personal distress. On a behavioural level, changes in perceptions might result in the inconsistent use of ineffective child-management strategies and dictatorial control (e.g., beta commands) at a time when parents seek to bound intera ctions with their children. The net consequence of such dynamics might be the expansion of what Patterson (1982) has termed coercive styles of family interactions. One of the issues linking to the emotional pattern of this kind of family breakdown is that of the divorce process, which shows the way to families living in single-parent households and eventually to the remarriage of one, if not both, parents and the formation of stepfamilies. This process, now believed likely to occur to one marriage in every three, also consequences in one in five children experiencing the divorce of their parents and the succeeding remarriage of at least one of them (conceivably more than once) during childhood.

Path loss determination using Hata model

Path loss determination using Hata model CHAPTER-1 INTRODUCTION Path loss is the degradation in received power of an Electromagnetic signal when it propagates through space. Path loss is due to several effects such as free space path loss, refraction, diffraction, reflection, coupling and cable loss, and absorption. Path loss depends on several factors such as type of propagation environments, distance between transmitter and receiver, height and location of antennas. Also the signal from the transmitting antenna may take multiple paths (multipath) to reach the receiving side, which results in either increase or decrease of received signal level depending on the constructive or destructive interference of the multipath waves. Path loss is usually expressed in decibels (db), as this method gives us an easy and consistent method to compare the signal levels at various points. Where Lp is the path loss i.e. the ratio of power of received signal to that of transmitted. Propagation models are used extensively in network planning, particularly for conducting feasibility studies and during initial deployment. They are also very useful for performing interference studies as the deployment proceeds. Numerous Experiments have been carried out all around the world, for checking the applicability of suitable path loss models in mobile communications specific scenario. In those experiments radio engineers carried out signal strength measurement for a specific area and compared the observed output with that of predicted outputs from different widely accepted propagation models so as to find out which model best predict the path loss for the given scenario. Also, some fine tuning for that model are done based on the difference. Many propagation models are available for path loss predictions. Deterministic models are based on the laws of electromagnetic wave propagation and produce accurate predictions of the path loss, however they take high computational effort and require detailed and accurate description of all objects in the propagation path .Free space Model, and Plane Earth model, are easier deterministic propagation methods. Empirical models are based on extensive collection of data for specific case. They are not accurate but predict the most likely behavior the link may exhibit under specific conditions. Okumura carried out a lot of field strength measurements in Tokyo, Japan with varying terrain, frequency antenna height and transmitted power. It states that, the signal strength decreases at much greater rate with distance than that predicted by free space loss .An empirical formula based on Okumuras results has been developed by Hata in order to make the propagation loss prediction easy to apply .Hata gave no of path loss models for urban, suburban and open areas, often called Okamura-Hata model. The European Co-operative for Scientific and Technical Research (COST) extended the Hata model to be valid for PCS(personal communication System) Operating at 1800- 2000 MHz, which is named COST 231 Hata model .The European research group also developed an another model taking Diffraction effect into consideration, which is COST 231 Walfish Ikegami model. Actually, this model is a semi-deterministic model as the path loss calculations is made by combining empirical models with deterministi c techniques [4].wave propagation models for planning of mobile communication network. Theres a North American model called Lees model named after W.C.Y. Lee, which is characterized by two parameters, power at a mile and path loss exponent. Kathmandu is the capital city of our country Nepal with more than 1 million inhabitants. GSM Mobile launched by Nepal Telecom reached almost a decade now with total 3.5 million subscribers, and 1.5 million solely in Kathmandu. With such increase in no. of subscribers, the no of BTS has gone up to 1500 in whole Nepal. Operating with both the frequency 900 and 1800 MHz, there are nearly 500 BTS (BS) in Kathmandu only. With such increase in the no. of Bs in Kathmandu valley due to the growth in No of subscribers, proper planning methods are needed for placing BTS for acceptable field strength and Interference level in the coverage area. Also the Coverage holes are needed to be filled with proper planning. This Planning Requires appropriate propagation models that best predicts the path loss for our specific environment. In this project, the feasibility analysis and fine tuning of Hata and Cost 231 Hata model has been done for propagation environments in Kathmandu. Taking three different areas of Kathmandu namely: Core city area, Ring-road area and Remote areas and five locations are selected for each of the terrain types and Field Strength Measurements offers a better means to understand what path loss model to use in certain propagation environments. Field strength measurements were conducted on the existing GSM 900 MHz Network of Nepal Telecom on the locations of interest. MOTIVATION The demand for increasing mobile subscribers needs efficient extension of a cellular network. For GSM like technology, there is additional complexity in making efficient Allocation of Base Stations and frequency planning. For this, proper path loss models should be used for coverage prediction and interference analysis. Much of the popular path loss models by renowned RF engineers are based on the observation data taken on their own country. So there is need of fine tuning of such model for applicability in our area. To my knowledge, there has not been any published work regarding such models feasibility analysis and modifications.This provides the impetus for this project to make an analysis of the observed data and necessary modification in Hata and Cost 231 Hata model for Kathmandu. Also, the proposed re-farming of 900 MHz frequency spectrum for Future Generation of Mobile Communications provides another drive for this project. It is obvious that use of less frequency yields large coverage area than higher frequencies. Hence, for future generation mobile, Scientist have conceived of making use of 900 MHz spectrum and together with use of newer technologies, they could make efficient utilization of this spectrum. APPLICATIONS This project can be used in realistic planning of GSM networks, with the predicted path loss in Kathmandu. For capacity enhancements of the network, GSM Engineers can use the path loss prediction models for intelligent placement of BTSs with certain antenna height and power. Path loss also facilitates Link budget analysis and Design in a telecommunication system. In a GSM like Cellular network, Path loss is used for Frequency Re-use distance estimates so as to properly space the channels in Base stations (BS). Actual Frequency assignment plans for the Base Stations are also facilitated by the use of path loss. Better Coverage predictions and interference reduction is what planning engineers get by using better path loss model. CHAPTER-2 PATH LOSS MODELS In this chapter, description of various Path Loss model will be discussed. The model characteristics, along with mathematical formulae, will be shown that is useful for further calculations, analysis in this project. In addition, three kinds of dependency factors of path loss will be noted that will be analyzed later. FREE SPACE PATH LOSS This model is the most simple and primitive path loss model where the influence of all objects and obstacles in the propagation environment is ignored. Here, the Received signal is inversely proportional to the square of distance between the transmitter and receiver. So, the free space Path loss is given by As Decibel (db) method gives us easy and consistent method to observe and analyze the signal levels at various points, the free space path loss can also be expressed in logarithmic format as OKAMURA MODEL This model is a RF propagation model that was developed based on the data collected in the Tokyo city, Japan. The model served as a base for all other empirical propagation models. In this model, the propagation area is divided into terrain categories: open area, suburban area, and urban area. Urban area is used as a reference area and Correction factors are applied in it to calculate the path loss for other terrains. HATA MODEL It is also known as the Okumura-Hata model for being a advanced version of the Okumura Model, is the most widely used model in radio frequency propagation for predicting the behavior of cellular transmissions in city outskirts and other rural areas. This model incorporates the graphical information from Okumura model and develops it further to better suit the need . Hata Model predicts the total path loss along a link of terrestrial microwave or other type of cellular communications. Operating frequency, Base Station Antenna height. This model is suited for both point-to-point and broadcast transmissions. COST 231 HATA MODEL It is also called the Hata Model DCS Extension, which is a RF propagation model that extends the Hata Model to cover a more range of frequencies. Also, this model is applicable to Open, Suburban and Urban Areas . PATH LOSS DEPENDENCY FACTORS Path loss usually depends on operating frequency, Base station Antenna Height, and distance of the Mobile stations (MS) from the Base Station (BS). For each of the popular empirical models discussed above, those dependency factors are observed separately and lastly combined together to give a formula for that path loss model. PATH LOSS EXPONENT We know that received signal at a distance from a BS or a transmitter is inversely proportional to some power of the distance, i.e. farther we go from the BS or transmitter, the received level will degrade by some factor. CHAPTER-3 For empirical models, Field strength measurements gives an easy and better way for feasibility analysis and fine tuning of the models for certain propagation environments. In our case, I intend to check the applicability and the modification of Hata and Cost 231 Hata model for propagation environments in Kathmandu. Three different terrains are taken into consideration, namely: Core city area, Ring-Road area, and remote area. Field strength measurements are carried out in fifteen different locations, where five of them belong to one terrain types. Location of BS, Transmitted power, antenna height is taken for the areas of interest in Kathmandu. Field strength measurements were conducted on the existing GSM network of Nepal Telecom and the receiver used was TEMS tool with a mobile set. DRIVE TESTING USING TEMS TEMS is an air interface test tool for real time diagnostic of different parameters for RF optimization. Also, all the data can be saved for later analysis. It consists of a laptop with TEMS software, a mobile set with a connector, GPS for location, and a hardware lock key. As for this project, only the received level is concerned, so the received level is noted as we drive farther from a BS. Above Figure shows the trail of the drive test path through a vehicle, in the location of interest. Here, the distance of a sample point in the trail can easily be noted using a scale in the map. Before performing drive test in all of those sites, proper Information regarding Site locations, their Carrier Frequencies, BS antenna Height, power transmitted from the BS are taken and used in the data collection and Calculations part. ASSUMPTIONS In this project, several assumptions are considered to ease data collection and analysis phase, which are listed as: Though the signal strength measurements are done for different BS with different Carriers (ARFCN), operating frequency is taken to be fixed at 900MHz. The effective power radiated from the BS is taken to be fixed at 50 dbm. Also height of mobile () taken to be fixed at 1.5 meters as the data is measured through TEMS inside a vehicle. Core city area, Ring-road Area and Remote areas in Kathmandu are assumed to be Urban, Sub-urban and Rural area respectively for simplification in analysis and comparison. If that assumption gives different result, then it can be rectified easily based on the integrated analysis of the path loss plot vs distance. MEASURED PATH LOSS For each of the propagation environments which have been selected and drive tested for data collection, the path loss can easily be calculated using the formula: So, Path loss can easily be observed from the collected data, to be increasing as we go farther from the BS. Data Collected for Fifteen different Locations can also be shown in tabular format as: PATH LOSS FROM MODELS After the observation of measured path loss in the propagation environments in Kathmandu, we need to calculate the path loss from the formula for the two models Hata and COST 231 Hata Model, with the distance d of MS from Bs in km, Frequency f in MHz, BS height hb in meters, Antenna height in meters taken from the actual scenario. Calculations are done using Excel sheet and the data are shown as: PATH LOSS PLOTS: As we get all the measured data and predicted data from the two models, the average data of path loss as shown in the table below are plotted with the increasing distance d of MS from BS as shown in the graph below for each propagation environments. COMPARISION AND ANALYSIS From the above plot for each propagation environments, comparing the average path loss values with that of Hata and COST 231 Hata model plot gives the result that Hata model best fits the propagation characteristics in Core city area and Ring-road area whereas the COST 231 model best predicts the propagation characteristics in Remote area. Also the Minimum Square Error (MSE)calculated for each of the model is within acceptable limits, which can be calculated using the formula: From the MSE analysis also, I find that Hata model best fits the Kathmandu Core city area and is also suitable for Kathmandu Ring-road Area. Whereas in the case of Kathmandu Remote Area, Cost 231 Hata model best predicts the path loss characteristics. FINE TUNING OF THE BEST FIT MODEL Due to the least and acceptable MSE in both Ring road area and remote area, the best fit models need not be modified for such propagation environments in Kathmandu. Solely based on the Minimum Square Error in path loss, the Best fit model for Core city area in Kathmandu i.e. Hata model can be modified accordingly. This formula is the modified version of the Path loss in urban area as given by Hata model for application in Kathmandu. CHAPTER-4 RESULTS By the comparison of the actual path loss with that of the predicted path loss from the two models Hata and COST 231 Hata model, and integrated analysis of all the plots, the feasibility analysis of the two models for three different propagation environments in Kathmandu is done. From which we get, Hata model is not feasible for the application in remote area due to much high minimum square error. Also the Hata model best fits the core city area in Kathmandu with MSE slightly greater than the acceptable limits as given by [6]. So the new modified Hata model is given based on the MSE. And for Ring-road area both model is applicable but the COST 231 Hata Model best fits it due to least MSE. CONCLUSION In this project, the popular empirical path loss models for mobile communications are studied. Among them two models, Hata and COST 231 Hata model is compared with actual path loss in three different propagation environments in Kathmandu, for applicability in macro-cellular Base Stations (BS). Comparison and Analysis of the integrated plot of the path loss from two models and actual path loss in those environments, along with mathematical calculations gave us the result. And the best fit model based on MSE calculations is either modified or left as it is, for those three propagation environments in Kathmandu. Also the assumptions for the three areas are consistent with the actual model which made the analysis and comparison easy. The choice of which model to use actually depends on the terrain type and the surrounding environments and objects around it, the selection of that model in planning a mobile communication network will give the best result and better network is what will be the output. So, Service providers must use efficient planning tools to better model their propagation environments along with the best predicted path loss. Hence, this project is useful for such realistic planning for GSM 900 MHz in Kathmandu. Further enhancements in this project can yield similar results for future mobile technologies and other spectrum too. PROBLEMS / LIMITATIONS: The receiver used for this project is a mobile set which has a sensitivity of -105 dbm. Hence, during field strength measurement, I can only measure signals up to 600m from the Base station in core city area. If there was separate equipment for signal measurement, it would have yield much better result, maybe thats the reason why there is much difference between the measured and predicted value due to lesser no of sample points. Also, Effective power radiated from the antenna is assumed to be 50 dbm, (same for all BS) due to unavaibility of measuring actual power radiated from the antenna and the losses in the RF cables and connectors. Also the antenna azimuth and down tilt not taken into consideration and sometimes, the measurement of received signal is done in locations that may be outside of the main lobe of the antenna radiation, i.e. outside of the half-power beam width (HPBW). FUTURE WORK: This work can be extended to apply for other mobile technologies in other frequency spectrum such as 1800 MHz DCS, 2100 MHz WCDMA. Also high sensitive field strength measurements tools can be used for future generation Mobile technologies for better result. As this project only dealt with the selection and modification of Path loss models for applicability in Kathmandu areas, the result of this project can be used for interference estimation and frequency assignment planning for new network or extension of existing network.
