What is Gsm Technology:-
GSM technology is known as “Global System for Mobile Communications”, and also known as “Global System for Mobile”. In 1982, the European Conference of Postal and Telecommunications Administrations (CEPT) created the Groupe Spécial Mobile (GSM) to develop a standard for a mobile telephone system that could be used across Europe.
In 1987, a memorandum of understanding was signed by 13 countries to develop a common cellular telephone system across Europe. Finally the system created by SINTEF led by Torleiv Maseng was selected.
In 1989, GSM responsibility was transferred to the European Telecommunications Standards Institute and phase I of the GSM specifications were published in 1990. The first GSM network was launched in 1991 by Radiolinja in Finland with joint technical infrastructure maintenance from Ericsson. After 1993, million subscribers were using GSM phone networks being operated by 70 carriers across 48 countries.
The GSM family of technologies has provided the world with mobile communications since 1991. In over twenty years of development, GSM has been continually enhanced to provide platforms that deliver an increasingly broad range of mobile services as demand grows. Where the industry started with plain voice calls, it now has a powerful platform capable of supporting mobile broadband and multimedia services.
How GSM works:-
GSM calls are either based on data or voice. Voice calls use audio codecs called half-rate, full-rate and enhanced full-rate. Data calls can turn the cell phone into a modem operating at 9600 bps. An extended GSM feature is high speed circuit switched data, allowing the phone to transmit upto around 40 kbps.
Importance of technology:-
GPRS or General Packet Radio Service is an extended service of GSM Network adding the ability to surf the Internet on your phone at slightly higher speeds. GPRS Internet surfing is comparable to dial-up Internet service in it's speed, operating at around 4 to 5... [continues]
