History of GSM
GSM began in 1991
GSM was a European wide project frombeginning
GSM used in more than 170 countries
Originated from 1G ->2G->2.5G->3G
3G version is named as UMTS 3G Network provide higher capacity than
the older generations

MOBILE COMMUNIC TION
1 G -analog (cellular revolution)
- only mobile voice services
2 G - digital (breaking digital barrier)- mostly for voice services & data delivery
possible
3 G - Voice & data ( breaking data barrier)
- Mainly for high speed data services where voice
will also be possible
Beyond 3G -Wide band CDMA ?
- But
surely higher data rates

First Generation & Second GenerationMobile System
Analog cellular systems are commonly referred toas first generation systems.
The digital systems currently in use, such as GSM,
PDC, CDMA one (IS-95), and US-TDMA (IS-136)are second generation system. These systemshave enabled voice communications to gowireless and customers are increasing finding
value also in other services such as textmessaging and access to data networks.

2G Mobile systems
2G Cellular Networks were first commerciallylaunched in Finland by Radiolinja in 1991
2G Cellular Networks are fully digital
2G Cellular Networks are very secure use
encryption
2G Cellular Networks provide basic data services

Spectrum for 2G Systems
At present GSM is operating in 900 MHz band - 890-915 MHz Uplink
935-960 MHz Downlink 1800 MHz band - 1710-1785 MHz Uplink
1805-1880 MHz Downlink 1900 MHz band - 1850-1910 MHz Uplink
