WHAT IS 5G ???
OR DEFINATION OF 5G
 5G refers to the fifth generation of cellular wireless standards
 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.
 The 5G communication system is envisioned as the real wireless
network, capable of supporting wireless world wide web (wwww).

7.
OBJETIVES OF5G
 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.

8.
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.
