3. What is fourth generation
(4G) mobile systems?
Fourth generation mobile communications
systems that are characterised 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 .

4. 4G: Anytime, Anywhere
Connection
Also known as ‘Mobile Broadband everywhere’
MAGIC

16. 4G Realities
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.
