  1. 1. Byharjeevan singh class -10th_E
  2. 2. 1st GENERATION:Introduced in 1980Analog cellular mobile,Data speed 2.4kbps1G mobiles- AMPS,NMT,TACSUses FDMA technique with30KHz
  3. 3. 2nd 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 were2.5 technologies.
  4. 4. 3rd 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 filesAdvantagesuniversal global roaming multimedia (voice , data & video)384 kbps while moving2mbps when stationary at specific l locationsvideo calling
  5. 5. 4th GENERATION: high-speed data accesshigh quality streaming videocombination of wi- fi andwi-maxSDR,OFDM,OFDMAand MIMO
  6. 6. WHAT IS 5G??? 5G is a packet switched wireless system with wide area coverage and high throughput.5G wireless uses OFDM andmillimeter wireless that enablesdata rate of 20 mbps andfrequency band of 2-8 GHz.5G is going to be a packedbased network.
  7. 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. 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.
  10. 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. 11. 4G Vs 5G 4G(2000-10) 5G(2010-15)Switching All packets All packetsService Dynamic Dynamic information information access, wearable devices access, wearable with AI capabilities devicesData rate Up to 20Mbps Up to 1 GbpsTechnology combination of combination of broadband, broadband, LAN/WAN/PAN/ LAN/WAN/PAN/WLAN WLAN and and wwww wwwwStandards Single unified Single unified standards standardsMultiplexing CDMA CDMA
  12. 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. 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.
