4G, the successor of 3G, will soonbecome the standard for cellular wireless

The technology is currently available insome countries but it is still beingperfected

The aim is to achieve ultra broadbandspeed to be counted in gigabytes persecond

ITU designed 4G in 2002 with the officialname 3G Long-Term Evolutions or 3.9G

Will allow users to download a full-lengthfeature film within five minutes

Will also be able to stream high-definitiontelevision and radio to hand-held devices

The basic difference between 3G and 4Gis in data transfer and signal quality

The highest download and upload speedin 3G are 14 Mbps and 5.8 Mbpsrespectively

In 4G the download speed is up to 100

Mbps for moving users and 1 Gbps forstationary users

4G is adoption of packet switching instead

of circuit switching in voice and video calls With packet switching, resources are onlyused when there is information to be sentacross

The first commercial deployment was byTelia Sonera and NetCom

Telia Sonera branded the network 4G

The modem devices on offer weremanufactured by Samsung

The network infrastructure were createdby Huawei (in Oslo) and Ericsson (in

Stockholm)

There are three primary technologies that

support 4G WiMax, LTE, and UMB

The main doubt is whether to implementWiMax or LTE

The advantages of LTE are:(i) Faster speed with 100 Mbps for downloadand 50 Mbps for upload(ii) It makes CDMA and GSM database moot(iii) It offers both FDD and TDD duplexing

WiMax technology might not achieve therequired rate in a high-density area

However, WiMax technology becomesuseful when it is bundled with IPTV

The wireless bandwidth will be roughly3Mbps/1.5Mbps; but this is nowhere nearthe +100Mbps/50Mbps that LTE promises

Has already begun the process ofintroducing 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 beavailable commercially

It has taken three years for the

government to decide on 3G-spectrumauction policy

4G could face the same delay unlessIndia wants to catch up with the rest of theworld
