What is fourth generation (4G) mobile
Fourth generation mobile communications systems that are
characterized by high-speed data rates at 20 to 100 Mbps, suitable
for high-resolution movies and television, virtual . Initial
deployments are anticipated in 2006-2010.
A recent study by Herschel Shosteck Associates noted that operators that pay
large amounts for spectrum will have to charge end users so much that
adoption of 3G will be slow.
Another study by Strategy Analytics agreed, predicting that, while wireless data
revenues will soar, 3G networks will account for less than a quarter of that
revenue by 2010. So-called 3G killer apps such as multimedia won't succeed,
the second study said.
Pent-up demand: Now there's the rub. Even NTT DoCoMo doesn't think
there's much pent-up demand among consumers for 3G multimedia services, so
it will target its initial 3G offering at business -- and price it accordingly.
OBJECTIVES OF 4G
Spectrally efficient system (8 bits/s/Hz)
High network capacity (atleast 10 times greater than 3G)
Nominal data rate at high speeds (100Mbps at stationary conditions and
20Mbps at 100miles/hr)
Smooth handoff across heterogeneous network
Seamless connectivity and global roaming across multiple networks
High quality of service for next generation multimedia support (real
time audio, high speed data, HDTV video content, mobile TV, etc)
Interoperable with the existing wireless standards
All IP system, packet switched network
