4G Features

INTRODUCTION
The approaching 4G (fourth generation) mobile communication
systems are projected to solve still-remaining
problems of 3G (third generation) systems and to provide
a wide variety of new services, from high-quality voice to
high-definition video to high-data-rate wireless channels.
The term 4G is used broadly to include several types of
broadband wireless access communication systems, not
only cellular telephone systems. One of the terms used to
describe 4G is MAGIC—Mobile multimedia, Anytime anywhere,
Global mobility support, Integrated wireless solution,
and Customized personal service. As a promise for
the future, 4G systems, that is, cellular broadband wireless
access systems, have been attracting much interest
in the mobile communication arena. The 4G systems not
only will support the next generation of mobile service, but
also will support the fixed wireless networks.
4G
This new generation of wireless is intended to complement
and replace the 3G systems, perhaps in 5 to 10
years. Accessing information anywhere, anytime, with a
seamless connection to a wide range of information and
services, and receiving a large volume of information, data,
pictures, video, and so on, are the keys of the 4G infrastructures.
The future 4G infrastructures will consist of a
set of various networks using IP (Internet protocol) as a
common protocol so that users are in control because they
will be able to choose every application and environment.
CONCLUSION
As the history of mobile communications shows,
attempts have been made to reduce a number of
technologies to a single global standard. Projected 4G
systems offer this promise of a standard that can be
embraced worldwide through its key concept of integration.
Future wireless networks will need to support diverse
IP multimedia applications to allow sharing of resources
among multiple users. There must be a low complexity of
implementation and an efficient means of negotiation
between the end users and the wireless infrastructure.
The fourth generation promises to fulfill the goal of PCC
(personal computing and communication)—a vision that
affordably provides high data rates everywhere over a
wireless network.
