Evolution of Mobile technology :
What is 4G ?
o In telecommunication systems
, 4G is the fourth generation of mobile phone
mobile communication technology standards. It Is
a successor to the third generation (3G)
standards. A 4G system provides mobile
ultra-broadband Internet access, for example to
laptops with USB wireless modems, to
smartphones, and to other mobile devices.
Conceivable applications include a mended mobile web access, IP telephony,
gaming services, high-definition mobile TV,
video conferencing, 3D television, and
cloud computing.
What’s new in 4G ?
o IP (Internet Protocol) based mobile systems.
o Entirely packet-switched networks.
o Digital in nature o Wider Bandwidths 100
Mhz10 times faster than current 3G
o Global mobility and service portability.
o User Friendly.

How 4G Works ?
• The IP address is based on IPv6.
• IPv4: X . X . X . X (32 bits)example: 216.37.129.9
• IPv6:4 × IPv4 (128 bits)
• example: 216.37.129.9 , 79.23.178.229 , 65.198.2.10 , 192.168.5.120
