Fourth generation also known as 4G is soon being the part of our world. The main advantages of this generation communication system is it have a higher data transfer rate.
The main objectives of 4G are:

1)4G will be a fully IP-based integrated system.

2)This will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors.

3)It can provide premium quality and high security.

4)4G offer all types of services at an affordable cost.



The downloading speed for mobile Internet connections is from 9.6 kbit/s for 2G cellular at present.4G mobile data transmission rates are planned to be up to 20 megabits per second which means that it will be about 10-20 times faster than standard ASDL services.In terms of connection seeds, 4G will be about 200 times faster than present 2G mobile data rates, and about 10 times faster than 3G broadband mobile. 3G data rates are currently 2Mbit/sec, which is very fast compared to 2G's 9.6Kbit/sec.
