WIRELESS SYSTEM

2. ABRIEF VIEW OR DEFINATION OF
GENERATIONS
 Generation refers change in nature of Service compatible
transmission technology and new frequency bands.
 1G systems used analog frequency modulation. and 2G systems
use digital communication techniques withTDM, FDM, CDMA.
 3G systems offer higher data rates and voice and paging services
to provide interactive multimedia including teleconferencing and
internet access.
 4G aims to provide IP telephony, ultra-broadband Internet access
gaming services.

3. 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).

4. 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.

5. 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.

6. 5G NETWORK REFRENCE MODEL

7. IPv6SUPPORT
 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.

9. BENEFITS OF5G
 High speed, high capacity, and low cost per bit.
 Support interactive multimedia, voice, streaming video, Internet, and other broadband
services ,more effective and more attreactive ,Bi directional ,accurate traffic statistics.
 Global access, service portability, and scalable mobile services.
 The high quality services of 5G technology based on Policy to avoid error.
 5G technology is providing large broadcasting of data in Gigabit which supporting
almost 65,000 connections.
 5G technology offer transporter class gateway with unparalleled consistency.
 Through remote management offered by 5G technology a user can get better and fast
solution.

10. Estimation of Global Wireless Subscriber
Growth

11. CONCLUSION
 Migration to 5G networks ensures convergence of
networks, technologies, applications and services.
 5G can serve as a flexible platform.
 Wireless carriers have an opportunity to shorten
Investment return, improve operating efficiency and
increase revenues.
 5G - a promising Generation of wireless
communication that will change people’s lives.
