WIRELESS COMMUNICATION
Wireless data networks use radio or infrared transmission andreception for computer communication.These are different fromtraditional data networks.Wireless networks are slower thancurrent wireline networks, and the disparity in speed makes itdifficult to design software that will operate well in eitherenvironment.

MOBILE COMMUNICATION
Wireless mobile systems introduces a new dimension totraditional distributed systems, which is untetherednetworking and unrestricted mobility. However, this excitingnew technology comes with the price of higher securityvulnerability.

4G
4G is the short term for fourth-generation wireless, thestage of broadband mobile communications that willfollow the still-burgeoning third generation (3G) that isexpected to reach maturity between 2003-2005. 4Gservices are expected to be introduced first in Japan, asearly as 2006 - four years ahead of the previous targetdate.

WHAT IS 4G
4G takes on a number of equally true definitions. InSimplest terms 4G is the next generation of wirelessnetworks that will replace 3G network sometimes infuture.4G is simply an initiative by academics R&D labs tomove beyond the limitations and problems of 3G which ishaving trouble getting deployed and meeting its promisedperformance and throughput

WHY WE NEED 4G
3G Performance may not be sufficient to meet needs
of future high performance like multi-media,fullmotion
video and teleconferencing.
Multiple standards for 3G makes it difficult to roam and
interoperate across network.
4G gives wider bandwidth.
4G has efficient modulation scheme than 3G.

WHAT IS NEEDED TO BUILD
4G NETWORK OF FUTURE
A number of spectrum allocation decisions, technologyinnovations, component development,signal processing andswitching enhancements and inter-vendor cooperation has totake place before the vision of 4G will materialize
Lower price points only slightly higher than alternatives-business

WIRELESS CARRIERS
(MobileVillage) -- Number portability is propellingwireless carriers into the role of primary communicationsprovider at a breakneck pace. Preparing to answer thecall, carriers are quickly shifting their focus from price toquality and customer service
“The network’s power and proximity to the customer maygive wireless carriers the advantage over outside contentproviders and application developers”.
