Introduction• Now-a-days the goal of

many customers is to have PC at one’s palm.

• To support such powerful systems we need long range, high speed wireless network called 4G.

#is the fourth generation of cell phone 

mobile communications.

#A 4G system provides mobile ultra-broadband Internet

access.

#A 4G system does not support traditional circuit-switched telephony service, but all-

Internet Protocol (IP) based communication such as 

IP telephony

About 4G !

4G is a fully IP-based integrated system as shown in Fig-1. This will be achieved after wired and wireless technologies converge and will be capable of providing 100 mbps and 1 gbps speeds both indoors and outdoors, with premium quality and high security .

EVOLUTIONThe first commercial deployment was by Telia Sonera and

NetCom.

Telia Sonera branded the network “4G”.

The modem devices on offer were manufactured by Samsung (dongle GT- B3710).

The network infrastructure were created by Huawei (in Oslo) and Ericsson (in

Stockholm).

4G IN INDIAHas already begun the process of introducing 4G

India is among the latecomers in 3G.

It is felt that by the time the implement 3G fully, 4G technologies such as LTE will be available

commercially.

It has taken three years for the government to decide on 3G-spectrum policy.

4G could face the same delay unless India wants to catch up with the rest of the world.

4G network in India• In India on 10 April 2012, India's telecom

company Bharti Airtel has launched India's first 4g services in Kolkata using TD-LTE technology. It's only 14 months back before the official launching in Kolkata when a group consisting of China Mobile, Bharti Airtel and SoftBank Mobile came together, called GTI (Global TDLTE Initiative) in Barcelona and they signed the commitment towards-LTE (Time-Division Long-Term Evolution) standards for the Asian region.

4G Possibilities•Broadband Access in Remote Locations

4G networks will provide a wireless alternative for broadband access to residential and business customers.

In addition, 4G will provide the first opportunity for broadband access in remote locations without an infrastructure to support cable or DSL access.

4G Possibilities

•Virtual Presence

Use hologram-generating virtual reality programs that provide an artificial presence just about anywhere.

For example, decide if you want to personally respond when someone rings your front door while you are away from home.

CONCLUSION

4G mobile phone technology promises faster communication Speeds , capacity and diverse usage formats.

These formats would provide richer content and support for other public networks such as optical fibre and wireless local area networks.
