INTRODUCTIONWHAT IS 4G?EVOLUTION OF 4GWHICH COUNTRIES HAVE 4G?4G EVOLUTION INTO CONVERGENCEWImax4G IN INDIA?

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

The technology is currently available in some countries but it is still being perfected

The aim is to achieve “ultra broadband speed” – to be counted in gigabytes per second

Introduction

ITU designed 4G in 2002 with the official name “3G Long-Term Evolutions” or 3.9GWill allow users to download a full-length feature film within five minutesWill also be able to stream high-definition television and radio to hand-held devicesThe basic difference between 3G and 4G is in data transfer and signal quality

What is 4G?

The highest download and upload speed in 3G are 14 Mbps and 5.8 Mbps respectivelyIn 4G the download speed is up to 100 Mbps for moving users and 1 Gbps for stationary users 4G is adoption of packet switching instead of circuit switching in voice and video calls4G uses spiral multiplexing

What is 4G? (Cont’d)

The 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)

Evolution of 4G

Except for the Scandinavian countries, a few countries have started the 4G commercially

In the US, Sprint Nextel initiated the service last year

Countries expected to launch 4G by this year are Germany, Spain, China, Japan and England

Which countries have 4G?

4G Evolution into Convergence

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

However, WiMax technology becomes useful when it is bundled with IPTV

The wireless bandwidth will be roughly 3Mbps/1.5Mbps; but this is nowhere near the +100Mbps/50Mbps that LTE promises

WiMax

Has already begun the process of introducing 4GIndia is among the latecomers in 3GIt is felt that by the time the implement 3G fully, 4G technologies such as LTE will be available commercially4G could face the same delay unless India wants to catch up with the rest of the world

4G in India?

THAT’S ALL ABOUT 4G
