    SYNOPSIS

    1. TITLE OF PROJECT:-

    Mobile Communication using GSM Technology; BSNL - A Case Study.

    2. OBJECTIVES OF THE STUDY:-

    To have complete familiarisation with the concepts of rapidlydeveloping field of mobile communication using GSM technology,

    which in the past 10 years not only have increased 40 fold butalso changed the life style of people & the way businesses weredone, thus resulting in complete telecom revolution.

    3. RATIONALE FOR THE STUDY:-

    (a) Over the years Phone on the move (mobile), has become anabsolute necessity than a mere luxury.

    (b) It has become an economically viable option for mostsection of the society.

    (c) Have resulted in high density of users who remainconnected anytime anywhere.

    (d) Innovative value added services made it the most popularcommunication system.

    (e) Being a user friendly system, more and more people aregetting attracted towards it day by day.

    So this study project is undertaken in order to contribute asmuch as possible towards the telecom revolution and be a partof the growth story of boosting economy.

    4. DETAILED METHODOLOGY USED FOR CARRYING OUT THESTUDY:-

    (a) Visit to BTS (Base Transceiver Station) at BRS Nagar,Ludhiana to see the antenna structure and the equipmentswith facilities of uninterrupted power supply.

    (b) Visit to BSC (Base Station Controller) at BN Chowk,Ludhiana to get a first hand experience on the basics of

    radio related functions and MS handover. Study themanuals available on site.

    (c) Visit the XCDR (Transcoder) system at BN Chowk, Ludhianato understand its operation and maintenance.

    (d)Visit to MSC (Mobile service switching centre) at Sec-34Chandigarh to get a first hand account of functioning ofdifferent essential systems. E.g. HLR (Home LocationRegister), AuC (Authentication Register), VLR (VisitorLocation register), EIR (Equipment Identification Register).Study the manuals available on site.

    5. THE EXPECTED CONTRIBUTION FROM THE STUDY:-

    a) Dissemination through IE(I) centers practical and technical

    realities described in the project will help the students ofcommunication engineering branches.

    b) This can be used as handy guide book for BSNL employees/perspective BSNL employees and engineers aspiring topursue a career in the field of mobile communications.

    History of Mobile Communication

  • 8/3/2019 fINAL Project With Synopsis

    11/78

    Wireless communication was a magic to our ancestors but Marconi could initiate it

    with his wireless telegraph in 1895.Wireless Communication can be classified into three

    eras.

    Pioneer Era (Till 1920)

    Pre Cellular Era(1920-1970)

    Cellular Era (beyond 1970)

    History - Pioneer Era (Till 1920) :-

    In 1946 f irst commercial mobile

    telephone system was launched by BELL in St.

    Louis, USA. Few lucky customers were getting

    the services .Early mobile systems were usingsingle high power transmitters with analog

    Frequency Modulat ion techniques to give

    coverage up to about 50 miles. Few customers

    on ly could get the serv ice due to severe

    constraints of bandwidth.

    History - CELLULAR ERA

    To overcome the constraints of bandwidth scarcity and to give coverage to larger

    sections, BELL lab introduced the principle of Cellular concept. By frequency reuse

    technique this method provides for better coverage, better utility of available frequency

    spectrum and reduced transmitter power. But the established calls are to be handed over

    Between base stations while the phones are on move

    Even though US based BELL lab introduced cellular principle, the Nordic countries were the

    first to introduce cellular services for commercial use with the introduction of the Nordic

    Mobile Telephone (NMT) in 1981.

    History - First Generation Systems

    12/78

    All these systems were analog systems, using FDMA. They are also known as First-

    Generation(1G)systems

    Different systems came into use based on cellular principle. They are listed below.

    Year Mobile System

    1981 Nordic Mobile Telephone(NMT)4501982 American Mobile Phone System(AMPS)

    1985 Total Access Communication System(TACS)

    1986 Nordic Mobile Telephony(NMT)900

    History of Mobile Communication

    To overcome the difficulties of 1G, digital technology was chosen by most of the

    countries and a new era started.

    Advantages

    Improved Spectral Utilization achieved by using advanced Modulation Techniques.

    Lower bit rate voice coding enabled more users getting the services simultaneously.

    Reduction of overhead in signaling paved way for capacity enhancement.

    Good source and channel coding techniques make the signal more robust to Interference.

    New services like SMS are included.

    Improved efficiency of access and hand-off control is achieved.
