the Global System for Mobile Communications, is an open, non
proprietary digital cellular system which has rapidly gain worldwide
acceptance and market share. In addition to digital transmission, GSM
incorporates many advanced series and features, including ISDN
compatibility, and worldwide seamless roaming in other GSM networks.
The advanced services and architecture of GSM have made it a model for
future 3G cellular systems such as UMTS.
GSM uses digital
technology and time division multiple access transmission methods
GSM is the basis of
powerful family of the platforms for the future- providing a direct
link into next generation solutions including GPRS, EDGE and 3GSM.
In GSM, Voice is
digitally encoded via a unique encoder, which emulates the
characteristics of human speech. This method of transmission permits a
very efficient data rate/information content ratio.
been a system designed with stringent levels of inbuilt security. With
constantly enhanced transmission protocols and algorithms added to the
flexible and future proof platform, GSM remains the most secure public
wireless standard in the world.
GSM Association, based
in Dublin, Ireland and London, UK, represents the interests of more
than 690 GSM, satellite and 3GSM operators, key manufacturers and
suppliers to the GSM industry as well as regulatory and administrative
bodies from more than 190 countries and regions around the world.
GSM Association is
responsible for the continued maintenance of open standards and
interoperability. The global cooperation between operators is most
powerfully illuminated by the success of international roaming. One of
