3. . 4G is short for Fourth (4th) Generation
Technology. It is basically the extension in
the 3G technology with more bandwidth and
services offers in the 3G.
 -A network that operates on Internet technology,
combines it with other applications and technologies
such as Wi-Fi, and runs at speeds ranging from 100
Mbps (in cell-phone networks) to 1 Gbps(in local
Wi-Fi networks).

8.  High Speed:– Data Rate of 100 Mbps for mobile
and 1 Gbps while stationary.
 Global Standard:-4G will be a global standard that
provides global mobility and service portability so that
service provider will no longer be limited by single-
system.
 Low Cost:– Access technologies, services and
applications can unlimitedly be run through wireless
backbone over wire-line backbone using IP address.
