WHAT IS 5G???
 5G is a packet switched
wireless system with wide
area coverage and high
throughput.
5G wireless uses OFDM and
millimeter wireless that enables
data rate of 20 mbps and
frequency band of 2-8 GHz.
5G is going to be a packed
based network.

OBJETIVES OF 5G:
 5G being developed to accommodate QoS rate requirements
set 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 of
the 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
standard to 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.
