By the end of the year 1980 the digital telecommunication standards were developed.

These systems provided better voice quality with higher capacity which even costed low.

3G:THIRD GENERATION

IMT-2000 is better known as 3G

3G provide faster communication services which include: voice ,fax internet. Broadband capabilities to support greater numbers of voice and video calls.

4G:FOURTH GENERATION

Support Interactive services like Video Conferencing, Wireles Internet,etc.

The networks will be all IP networks based on IPv6.

4G networks provide speeds of 100 Mbps while moving and 1 Gbps while stationary.
