  1. 1. 4G<br />By<br />MrinmoyMukherjee<br />
  2. 2. 4G<br />Generation of cellular wireless<br />4G<br />3G<br />2G<br />1G<br />
  3. 3. 3G<br />1G & 2G<br />4G<br />- Extremely high available bandwidth<br />- High-speed data access and video<br />Conferencing<br />- Worldwide roaming<br />using a single handheld device.<br />FEATURES<br />
  4. 4. An overview of 1G, 2G, 3G<br /><ul><li>First-generation of wireless telephone technology, mobile telecommunications
  5. 5. Telecommunications standards that were introduced in the 1980s
  6. 6. Uses digital signaling to connect the radio towers to the rest of the telephone system
  7. 7. launched on the GSM standard in Finland by Radiolinja in 1991
  8. 8. Phone conversations were digitally encrypted
  9. 9. Lower power emissions helped address health concerns.
  10. 10. Lower powered radio signals require less battery power
  11. 11. All-digital allowed for the introduction of digital data services, such as SMS and email.
  12. 12. Enhanced privacy
  13. 13. 3rd Gene is a family of standards for mobile telecommunications
  14. 14. The first pre-commercial 3G network was launched by NTT DoCoMo in Japan
  15. 15. 3G networks offer a greater degree of security than 2G predecessors
  16. 16. Services include </li></ul>-wide-area wireless voice telephone, <br /><ul><li>video calls
  17. 17. wireless data</li></ul>3G<br />1G<br />2G<br />
  18. 18. Comparison of 1G&2G<br />The main difference between two succeeding mobile systems 1G and 2G is that the radio signals that 1G network uses are analog, while 2G network are digital<br />In comparison to 1G’s analog signal, 2G’s analog signal are very reliant on location and distance. <br />Although both systems use digital system use digital signaling to connect the radio tower to the rest of the telephone systems. The voice itself during a call is encoded to digital signals in 2G, where 1G is only modulated to higher frequency<br />
  19. 19. 4G<br />The term 4G is used broadly to include several type of broad band, wireless access communication systems, not only cellular telephone systems. <br />The new generation of wireless is intended to compliment and replace the 3G system. <br />4G can also be defined as “MAGIC”<br /> M- Mobile Multimedia<br /> A-Anytime Anywhere<br /> G-Global Mobility Support<br /> I-Integrated Wireless Solution<br /> C-Customized personal service<br />

  21. 21. 8<br />4G an overview<br />2G – 2nd Generation Mobile System<br />GSM, IS-95, cdmaOne<br />Low-bit-rate data<br />3G – 3rd Generation Mobile System<br />Higher-data-rate service<br />New technology<br />GPRS<br />IMT-2000<br />Bluetooth<br />WLAN<br />HiperLAN<br />Independent systems, all have there own shortcomings<br />A single system is needed to replace all of them – 4G<br />
  22. 22. 4G-Features<br />These features means services can be delivered and be available to the personal preference of different users and support the users traffic, Air interfaces, Radio environment and quality of services.<br />The 4G systems, will inter-operate with the 2G and 3G systems as well as with, digital broadcasting system.<br />The key concept is integrating the 4G capabilities with all of the existing mobile technologies through advanced technologies. <br />
  23. 23. Key attributes of 4G<br />
  24. 24. Support for Multiple Applications and Services <br /><ul><li>Efficient support for unicast, multicast and broadcast services and the applications that rely on them.</li></ul>Quality of Service <br />Consistent application of admission control and scheduling algorithms regardless of underlying infrastructure and operator diversity.<br />
  25. 25. Network Detection and Network Selection <br />A mobile terminal that features multiple radio technologies or possibly uses software defined radios if economical, allows participation in multiple networks simultaneously<br />Seamless Handover and Service Continuity <br />Support for this function requires continuous transparent maintenance of active service instances and inclusion of various access technologies, from WiFi<br />
  26. 26. Technology and Topology Independence <br />Services not constrained by topology or technology limitations, but rather achieve the “Always Best Connected” characteristic.<br />Conclusion<br />It is inevitable that 4G would completely replace 3G in long run.<br />In order for 4G to grow on the future market, it is unavoidable to compute with 3G and acquire 3G’s customer.<br />
