A BRIEF VIEW OR DEFINATION OFGENERATIONS
Generation refers change in nature of Service compatibletransmission technology and new frequency bands.
1G systems used analog frequency modulation. and 2G systems
use digital communication techniques with TDM, FDM, CDMA.
3G systems offer higher data rates and voice and paging servicesto provide interactive multimedia including teleconferencing and
internet access.
4G aims to provide IP telephony, ultra-broadband Internet accessgaming services.

WHAT IS 5G ???
OR DEFINATION OF 5G
5G refers to the fifth generation of cellular wireless standards
5G is apacket switched wireless system with wide area coverageand high throughput.
5G wireless uses OFDM and millimeter wireless that enables datarate of 20 mbps and frequency band of 2-8 GHz.
5G is going to be apacked based network.
The 5G communication system is envisioned as the real wirelessnetwork, capable of supporting wireless world wide web (wwww).

OBJETIVES OF 5G
5G being developed to accommodate QoS rate requirementsset by further development of existing 4G applications.
Flexible channel bandwidth between 5 and 20MHz,
optionally up to 40MHz.
Data rate of at list 1Gb/s between any two points in the
world.
Increase system spectral efficiency of up to 3bit/s/Hz/cell in
the downlink and 2.25bit/s/Hz/cell for indoor usage.

STANDARD WIRELESS 5G
WiMAX formed to provide conformance and interoperability ofthe IEEE 802.16 standard. It aims to provide wireless data over
long distance from point-to-point link to cellular mobile type
access.
WiBRO a part of IEEE 802.16e in process to provide
collaborative and generic mobile WiMAX.
3GPP LTE a project aims to improve the mobile phone standardto cope with future requirements.
5GPP 2 UMB a project to improve the CDMA2000 mobile
phone standard for next generation applications.

IPv6 SUPPORT
IPv6 increases the IP addresses size from 32bit to 128
bits, to support more levels of addressing hierarchy and
much greater number of addressable node.
IPv6 support large number of wireless enabled devices.
IPv6 Extend the IP address space enough to offer a
unique IP address to any device.
IPv6 Improve support for IP Mobility.
