The development of GSM started in 1982, when the Conference of European Posts and Telegraphs (CEPT) formed a study group called Group Special Mobile (the initial meaning of GSM). The group was to study and develop a pan-European public cellular system in the 900 MHz range, using spectrum that had been previously allocated. At that time, there were many incompatible analog cellular systems in various European countries. Some of the basic criteria for their proposed system were: • Support for international roaming. • Good speech quality • Ability to support handheld terminals • Low terminal and service cost • Spectral efficiency • Support for a range of new services and facilities • ISDN compatibility.

    OVERVIEW OF THE GSM CELLULAR SYSTEM
    (2013-10-01T04:42:37Z) PAWAR, GAURI
    GSM, the Global System for Mobile communications, is a digital cellular communications system which has rapidly gained acceptance and market share worldwide, although it was initially developed in a European context. In addition to digital transmission, GSM incorporates many advanced services and features, including ISDN compatibility and worldwide roaming in other GSM networks. The advanced services and architecture of GSM have made it a model for future third-generation cellular systems. This paper will give an overview of the, the system architecture, and services offered by GSM.
