5 g mobile technology

  1. 1. ByFaldu Anand 090380116022
  2. 2. Introduced in 1980s & completed inearly 1990s.Analog cellular mobile,Data speed up to2.4kbps.1G mobiles- AMPS,NMT,TACS.AMPS first launched by US & it is 1Gmobile system.Uses FDMA technique with 30KHz.Allows users to make voice calls in 1country.
  3. 3. Introduced in late 1980s & finished inlate 1990s.Digital cellular systems that are usedtoday.Voice transmission with digital signal.Digital modulation schemes-TDMA,CDMA.Data speed in 2G is up to 64kbps.During the second generation, themobile telecommunications industryexperienced exponential growth in terms ofboth subscribers and value-added services.
  4. 4. Generation between 2G and 3G.2.5G networks, such as General PacketRadio Service (GPRS), are an extension of2G networks .In this they use circuit switching forvoice and packet switching for datatransmission resulting in its popularitysince packet switching utilizes bandwidthmuch more efficiently.
  5. 5. In this system, each user’s packetscompete for available bandwidth, andusers are billed only for the amount ofdata transmitted.Failure in bringing any new evolution .Data speed in 2.5G is up to 144kbps.GPRS, EDGE and CDMA 2000 were2.5G technologies.
  6. 6. 3G technology is intended for truemultimedia cell phone.3G networks were proposed to eliminatemany problems faced by 2G and 2.5Gnetworks, especially the low speeds andincompatible technologies such as TimeDivision Multiple Access (TDMA) andCode Division Multiple Access (CDMA)in different countries.Speeds from 125kbps-2Mbps.
  7. 7. In theory, 3G should work over NorthAmerican as well as European and Asianwireless air interfaces.In reality, the outlook for 3G is not verycertain. Part of the problem is thatnetwork providers in Europe and NorthAmerica currently maintain separatestandards’ bodies (3GPP for Europe andAsia; 3GPP2 for North America).
  8. 8. The standards’ bodies have not resolvedthe differences in air interfacetechnologies.There is also a concern that in manycountries 3G will never be deployed due toits cost and poor performance.Although it is possible that some of theweaknesses at physical layer will still existin 4G systems, an integration of services atthe upper layer is expected.
  9. 9. Performance in computer networking(WCDMA, WLAN Bluetooth) & mobiledevices area (cell phone & GPS).Access to Global Roaming & Clarity invoice calls, Fast Communication, Internet,Mobile T.V, Video Conferencing, VideoCalls, (MMS), 3D gaming etc .
  10. 10. The future of mobile systems is largelydependent upon the development andevolution of 4G systems, multimedianetworking, and upto some extent,photonic networks.It is expected that initially the 4Gmobile systems will be used independentfrom other technologies.high-speed data access.high quality streaming video.combination of wi-fi and wi-max.Smooth global roaming with lower cost.
  11. 11. In addition, developments in photonicswitching might allow mobilecommunication on a completely photonicnetwork using Wavelength DivisionMultiplexing (WDM) on photonicswitches and routers.These technology arrival in 2010 –2015.SDR,OFDM,OFDMA and MIMO.
  12. 12. The evolutionary view of 4Gsystems to 5G includes a support ofwireless World Wide Web allowing ahighly flexible and reconfigurabledynamic networks.5G is a packet switched wirelesssystem with wide area coverage andhigh throughput.Complete wireless communicationwith almost no limitation.Advanced features: powerful andin huge demand in future.
  13. 13. 5G wireless uses OFDM andmillimeter wireless that enables datarate of 20 mbps and frequency bandof 2-8 GHz.5G is going to be a packed basednetwork.Faster data transmission that ofthe previous generations.Multi-Media Newspapers, watchT.V programs with the clarity as tothat of an HD T.V.large phone memory, dialing speed ,clarity in audio and video etc.
  14. 14. World Wide Cellular phonesExtra ordinary data capabilitiesHigh connectivityBright futureFlexible channel bandwidth between 5 and 20MHz, optionallyup to 40MHz.Data rate of at least 1Gb/s between any two points in theworld.Increase system efficiency up to 3 bit/s/Hz/cell in the downlinkand 2.25 bit/s/Hz/cell for indoor usage.
  15. 15. 5G terminals will have software defined radios.New error-control schemes.Access to different wireless technologies.Combine different flows from different technologies.Choice among different wireless/mobile access.Network providers for a given service.
  16. 16. Table 1: Comparison of 1G-5G Technologies
  17. 17. High resolution, bi-directional large bandwidth shaping.Advanced billing interfaces: attractive and effective.Subscriber supervision tools for fast action.High quality services based on Policy to avoid error.Large broadcasting of data (GB) supports almost 65,000connections.Transport class gateway with unparalleled consistency.More accuracy by traffic statistics.Remote management :better and fast solution.Remote diagnostics1Gbps connectivity speed.Virtual private network.
  18. 18. All delivery service out of business prospect.High uploading and downloading speed enhanced and available connectivity just about the world.High speed, high capacity, and low cost per bit.Support interactive multimedia, voice, streaming video, Internetand other broadband services.Global access, service portability, and scalable mobile services.Through remote management offered by 5G technology a user canget better and fast solution.
  19. 19. Wearable devices with AI(Artificial Intelligence) capabilities.Global Network.Media independent handover.Radio resource management.VoIP(Voice Over IP) enabled devices.With 6th sense technology.
  20. 20. A new revolution of 5G technology will going to toughcompetition to normal computers and laptops whose market valuewill be affected.The coming up 5G technology will available in the market inaffordable rates, high peak future and much reliability than itspreceding technologies.5G can serve as a flexible platform and wireless carriers have anopportunity to shorten investment return, improve operatingefficiency and increase revenues.Nowadays we are using 2G and 3G technologies and 4Gtechnologies will coming soon, but in future we will want to ready toface 5G technologies and its some features.
