ABSTRACT
Definition:
GSM, which stands for Global System for Mobile communications, reigns (important) as the world’s most widely used cell phone technology. Cell phones use a cell phone service carrier’s GSM network by searching for cell phone towers in the nearby area. 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.
Need of GSM:
The GSM study group aimed to provide the followings through the GSM:
• Improved spectrum efficiency.
• International roaming.
• Low-cost mobile sets and base stations (BS)
• High-quality speech
• Compatibility with Integrated Services Digital Network (ISDN) and other telephone company services.
• Support for new services.
