ABSTRACT
Global system for mobile communication (GSM) is a globally accepted standard for digital cellular communication. GSM is the name of a standardization group established in 1982 to create a common European mobile telephone standard that would formulate specifications for a pan-European mobile cellular radio system operating at 900 MHz. It is estimated that many countries outside of Europe will join the GSM partnership.Throughout the evolution of cellular telecommunications, various systems have been developed without the benefit of standardized specifications. This presented many problems directly related to compatibility, especially with the development of digital radio technology.
(GSM: originally from Group Special Mobile) is the most popular standard for mobile phones in the world.the GSM digital standard was proven to work in 1988. In GSM both signalling and speech channels are both digital call quality and hence is considered as 2G mobile phone system.This has also meant that data communication were built into the system using the 3rd Generation Partnership Project (3GPP).The digital nature of GSM allows the transmission of data (both synchronous and asynchronous) to or from ISDN terminals, although the most basic service support by GSM is telephony band.The GSM logo is used to identify compatible handsets and equipment .
