LOGO 4G WIRELESS SYSTEM
4G is the fourth generation wireless network communications technology
Standard.
This new generation of wireless is intended to complement and replace the
3G systems.
The 4G infrastructures will consist of a set of various networks using IP
(Internet protocol) as a common protocol.
The 4G systems will inter operate with 2G and 3G systems, as well as with
digital (broadband) broadcasting systems.
In addition, 4G systems will be fully IP-based wireless Internet.

LOGO FUTURE
Both service providers and users want to reduce the cost ofwireless systems and the cost of wireless services.
Lesser the expensive of the system, the more people who will
want to own it.
4G's flexibility will allow the integration of several different
LAN and WAN technologies.
Finally, the 4G wireless system would truly go into a "one size
fits all" category, having a feature set that meets the needs of
just about everyone.
