Fourth generation (4G) Mobiles
4G also called as Fourth Generation Communication System, is a term used to describe the next step of wireless communication.A 4G system can provide a comprehensive IP solution where voice,data and streamed multimedia can be provided to users on an "Anytime,Anywhere" basis.The data transfer rates are also much higher than previous generations.
In terms of connection speeds,4G will be about 200 times faster than present 2G mobile data rates and about 10 times faster than present 3g broadband mobile.3g data rates are currently 2Mbit/s, which is very fast compared to 2G's 9.6 Kbit/s

The main objectives of 4G are:
- 4G will be fully IP-based integrated system.
- This will be capable of Providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors.
- It can provide premium quality and high security.
- 4G offers all types of services at an affordable cost.

Data Rates For 4G :
The downloading speed for mobile internet connections from 9.6 Kbit/s for 2G cellular at present.However,in actual use the data rates are usually slower,especially in crowded areas , or when there is congestion in network.
4G mobile data transmission rates are planned to be up to 20Mb/s which means that it will be about 10-20 times faster than standard ASDL services.
