1 Cellular System Rajat Chugh, Parag Jasoria, Tushar Arora, Nitin Ginotra and Vivek Anand V Semester, Department of Computer Science and Engineering, Dronacharya College of Engineering, Khentawas, Farukhnagar, Gurgaon, India Abstract:-Our paper is based on the concept of cellular system In this paper we are giving the basic concept of the cellular system and about the various pros and cons of the cellular system.cellular system is the geographic region subdivided into the radio cells In this several small exchanges equipped with the low power radio antennas are interconnected through a central exchange.we know that cell phones have been at the centre of controversy and skepticism,but they have also been praised for usefulness and their inevitability GOAL The main goal of the cellular system is to provide communication services to a large number of mobile users.the main aim of cellular system is to provide personal telephone services to subscribers on the move.the largest demand for this service at present is the telephone in his car used by the person mean facility of communication on moved at may be by foot, bicycle etc. INTRODUCTION Cellular mobile radio telephony is a significant step forward in the provision of communication services.cellular system have evolved from military radio design.but their practicability for civilian application has become possible due to the recent technologies.in mobile telephony it is necessary to change the operating frequency as one moves from transmitter area to another. In traditional military mobile radio change of operating frequency is tedious involving manual retuning of circuits and readjustment of antennas In modern cellular system operating frequencies can be changed many times in second under the control of microprocessor and pseudo generators The cellular network is viewed by the PSTN as just another end-office where calls originate and terminate. The STP (signal transfer point) handles the network routing by establishing the route to the HLR (home location register) for a specific mobile user. This simplifies network management, because only the routing tables in the STP need to be updated as the system grows. Each MSC (mobile switching center) does not have to maintain full routing tables to all other MSC 1

2 FUNDAMENTAL CONCEPT IN BASIC SYSTEM In a cellular network, each cell uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed bandwidth within each cell. In a cellular radio system, a land area to be supplied with radio service is divided into regular shaped cells, which can be hexagonal, square, circular or some other regular shapes, although hexagonal cells are conventional. Each of these cells is assigned multiple frequencies (f 1 - f 6 ) which have corresponding RADIO BASE STATION The group of frequencies can be reused in other cells, provided that the same frequencies are not reused in adjacent neighboring cells as co channel interfaces The increased capacity in a cellular network, compared with a network with a single transmitter, comes from the fact that the same radio frequency can be reused in a different area for a completely different transmission. If there is a single plain transmitter, only one transmission can be used on any given frequency PERFORMANCE CRITERIA 1. VOICE QUALITY 2. SERVICE QUALITY Voice quality is complicated parameter for design engineers because it depends person to person and also mobile user not uses a common equipment. 2.SERVICE QUALITY:- grade of service coverage area OPERATIONS OF CELLULAR SYSTEM Operation of cellular system is fully automatic and no manual actions require rather than calling and answering there are various type of channel for various purposes between mobile phone and network which are use for call conversation or for data transmission basically channels are divided in 2 parts:- 1. Physical Channel 2. Logical Channel 2

3 As we know from previous discussion cellular system particularly GSM is based on TDMA and FDMA both TDMA (time division multiple acess )divides one radio frequency channel into consecutive periods of time each on called a TDMA frame. Each TDMA frame contains eight shorter periods of time known as time slots. TDMA time slots are called physical channel as they are used to physically move information from one place to another and for the purpose time slots used in network called logical channel. In Cellular Network Logical Channels Are Divided Into 2 Types:- 1. Dedicated channels. 2. Common channels. Dedicated channels allocated to mobile phone for call conversation data transmission and if it is allocated once then it cannot be share with another mobile phone subscriber until mobile phone terminate his call while common channels use for keeping record of subscriber position authentication searching for subscriber following are more classification of common channels and dedicated channels. ANALOG CELLULAR SYSTEM Analog cellular system is a first generation (IG) cellular system. In early 1980,when cellular system was on evolving stage then the first in system named as advance mobile phone services (AMPS) developed by AT and t. This service was employed in North America South America China Australia etc Each AMPS include a Numeric Assignment Module (NAM) in read only memory. The NAM contains the telephone number of the phone which is assigned by the service provider, and serial number of phone which is assigned by the service provider and serial number of phone, which is assigned by manufacturer when the phone is turned ON it transmits its serial number and phone number to NSS. NSS maintains the database of user for billing purpose or for blocking the call. HOW CALL IS MADE 1. The subscriber dialed number and push the send button. 2. NSS verifies that the telephone number is valid and subscriber is authorized to use the service. 3. NSS issues a message to the user cell indicating which traffic channels to use for sending and receiving. 4. The NSS sends out a ringing signal to the called party. 5. when the called party gives the information the NSS establish the relation between 2 parties and starts the billing operation. 6. When one party hangs up the NSS release the circuit and free the radio channels. DIGITAL CELLULAR SYSTEMS In 1992,the first digital cellular system GSM was deployed in Germany GSM is in Europian standard system. In the USA an NA-TDMA system and a CDMA system have been developed.na-tdma was developed in 1993 and CDMA IN 1995.Digital cellular system is a second generation cellular system like GSM CDMA cordless phone etc. Cell service area may also vary due to interference from transmitting systems, both within and around that cell. This is true especially in CDMA based systems. The receiver requires a certain signal-to-noise ratio, and the transmitter should not send with too high transmission power in view to not cause interference with other transmitters. GSM GSM (Global System for Mobile communication) is a digital mobile telephony system that is widely used in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA) and is the most widely used of the three digital wireless telephony technologies (TDMA, GSM, and CDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. It operates at either the 900 MHz or 1800 MHz frequency band Mobile services based on GSM technology were first launched in Finland in

4 GSM services across 213 countries and GSM represents 82.4% of all global mobile connections. According to GSM World, there are now more than 2 billion GSM mobile phone users worldwide. GSM World references China as "the largest single GSM market, with more than 370 million users, followed by Russia with 145 million, India with 83 million and the USA with 78 million users.". SIM cards (Subscriber Identity Module) holding home network access configurations may be switched to those will metered local access, significantly reducing roaming costs while experiencing no reductions in service. EDGE Enhanced Data rates for GSM Evolution (EDGE) (also known as Enhanced GPRS (EGPRS), is a digital MOBILE PHONE technology that allows improved data transmission rates EDGE/EGPRS is implemented as a bolt-on enhancement for 2.5G GSM/GPRS networks, making it easier for existing GSM carriers to upgrade to it. EDGE is a superset to GPRS and can function on any network with GPRS deployed on it, provided the carrier implements the necessary upgrade. EDGE requires no hardware or software changes to be made in GSM core networks. EDGE-compatible transceiver units must be installed and the base station subsystem needs to be upgraded to support EDGE. If the operator already has this in place, which is often the case today, the network can be upgraded to EDGE by activating an optional software feature. Today EDGE is supported by all major chip vendors for both GSM and WCDMA/HSPA. 4

5 GPRS General Packet Radio Service is a packet-switching technology that enables data transfers through cellular networks. It is used for mobile internet, MMS and other data communications. In theory the speed limit of GPRS is 115 kbps, but in most networks it is around 35 kbps. Informally, GPRS is also called 2.5G. In theory, GPRS packet-based services cost users less than circuit-switched services since communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated to only one user at a time. It is also easier to make applications available to mobile users because the faster data rate means that middleware currently needed to adapt applications to the slower speed of wireless systems are no longer be needed. As GPRS has become more widely available, along with other 2.5G and 3G services, mobile users of virtual private networks (VPNs) have been able to access the private network continuously over wireless rather than through a rooted dial-up connection. STRENGTHS OF CELLULAR SYSTEMS Cellular system offer a number of advantages over alternative solutions: increased capacity reduced power use larger coverage area reduced interference from other signals WEAKNESS OF CELLULAR SYSTEM Need for more infrastructure Need for fixed network to connect Base Stations Some residual interference from co-channel Handover procedure required CONCLUSION We covered all the technologies in the cellular system and conclude that with the advancement of the technology and with the increasing demands of the people new procedures are been developed The explosive growth of mobile wireless usage and ever increasing need for high-speed data services accelerated the need for the deployment of 3G technologies REFERNCES 1.
