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
