2. 1 st GENERATION:  Introduced in 1980  Analog cellular mobile,Data speed 2.4kbps  1G mobiles- AMPS,NMT,TACS  Uses FDMA technique with 30KHz

3. 2 nd GENERATION:  Digital cellular systems  Digital modulation schemes- TDMA,CDMA  Data speed in 2g is up to 64kbps  Data speed in 2.5g is up to 144kbps  GPRS, EDGE and CDMA 2000 were 2.5 technologies.

4. 3 rd GENERATION:  3g technology is intended for true multimedia cell phone  typically called smart phones and features increased bandwidth and transfer rates to accommodate wed-based applications and phone-based audio and video files Advantages  universal global roaming multimedia (voice, data & video) 384 kbps while moving 2mbps when stationary at specific l locations video calling

5. 4 th GENERATION: high-speed data access high quality streaming video combination of wi-fi and wi-max SDR,OFDM,OFDMA and MIMO

6. 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.

7. 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.

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.

9. 5G NETWORK REFRENCE MODEL:

10. 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.

11. 4G Vs 5G 4G Vs 5G 4 G(2000-10) 4 G(2000-10) 5G (2010-15) 5G (2010-15) Switching All packets All packets All packets Service Dynamic information access, wearable devices Dynamic information access, wearable devices with AI capabilities Data rate Up to 20Mbps Up to 1 Gbps Technology combination of broadband, LAN/WAN/PAN/ WLAN and wwww Standards Single unified standards Multiplexing CDMA CDMA

12. BENEFITS OF 5G:  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.

13. 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.
