Mobile Evolution



Till now there are mainly 4 generations observed in mobile technology.

These are 1G, 2G, 2.5G and 3G.

1G came as Advanced mobile system in 1983.

2G was introduced in 1998 in U.S.A.

3G was introduced in late 2008.

4G is still in development stage.


Edge technology


EDGE is a high speed mobile data standard.

Uses TDMA and follows GSM.

Transmits data at up to 384 kbits per second.

Builds on General Packet Radio Service (GPRS) air interface and networks


Channel coding


Uses Gaussian minimum-shift keying (GMSK).

Also uses higher-order phase shift keying (8PSK) for the upper five of its nine modulation and coding schemes.

EDGE produces a 3-bit word for every change in carrier phase.


Major Applications


EDGE enables operators to introduce 3G data applications into existing GSM networks.

It enables:-
Mobile Internet access

Mobile Office

 Electronic banking

Electronic cash

Electronic payment
