3G vs 4G

What’s new in 4G ?

o IP (Internet Protocol) based mobile systems.

o Digital in nature o Wider Bandwidths 100Mhzo 10 times faster than current

3Go User Friendly.

Technology Standards :

• LTE (In Norway ,Sweden since 2009)

• The advantages of LTE(Long Term Evolution) are:(i) 100 Mbps - download & 50 Mbps – upload.(ii) It offers both FDD (Feature Design Document) and

TDD (Test Driven Development) duplexing.

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
