ADVANTAGES:ADVANTAGES:

You get Internet on the go. This is

primary advantage of 4G

Fast download speed and connectionspeed

huge range of coverage area- entire city

can be covered.

sate light provider- watch live TV

it can improve business efficiency.

The most important : works on OFDM

AvailabilityAvailability

4G is still not available in India.

In U.S few countries are having 4G

wireless network as beginner.

The Clear and Wi-max are the first two

companies that started 4G wireless

network.

CONCLUSION

The proposed wireless systemdiscussed above may provide a unique

solution for the highway portion of the

high-bandwidth global communication

system of the future.

4G networks may eventually deliver

on all the promises. These advances will make

high-speed data/voice-over-Internet-protocol

(VoIP) networks a reality
