MAINTAINANCE OF GSM TRANSMISSION SYSTEM
Introduction
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
The Global System for Mobile communications is a digital cellular communications system. It was developed in order to create a common European mobile telephone standard, but it has been rapidly accepted worldwide. GSM was designed to be compatible with ISDN services.
But in the beginnings of cellular systems, each country developed its own system, which was an undesirable situation for the following reasons:
- The equipment was limited to operate only within the boundaries of each country.
- The market for each mobile equipment was limited.
