  • 3. INTRODUCTION
    4G is the next major generation of mobile cellular systems, to be deployed around the year 2010
    4G networks are projected to provide speeds of 100 Mbps while moving and 1 Gbps while stationary.
  • 4. What is 4g?
    New Technology Advancements
    • Radio Technology - Orthogonal Frequency-Division Multiplexing (OFDM)
    • 5. Antenna - Multiple Input-Multiple Output (MIMO)
    Improved Performance
  • What is 4g?
    Evolved Packet Core (EPC)
    • Machine-to-Machine
    • 8. Real-time Mobile Video, etc.
    • 9. Fixed Mobile Convergence
    • 10. Transport Interworking - Flat IP/MPLS Infrastructure
    IP Multi-Media Subsystem (IMS)
    • Enhanced Communications Services
    • 11. Wireless and Wireline Convergence
    • 12. Network Based Services โ€“ Gateways/Servers
  • A VIEW OF 4G
    • Domain of 4G extends beyond 1G, 2G, and 3G
    • 13. > 2 Mbps in a wide-area mobile system (> 20 Mbps peak)
    • 14. Could coexist with 2G and 3G
    • 15. 4G is not necessarily defined by the bit rate, but by a significant advance in system capability beyond what can be achieved with 3G
  • 3G vs. 4G
  • 16.
  • 17. 4G ARCHITECTURE
  • 18. COMMUNICATIONS SCENE OF TODAY
  • 19. Mobile evolution
  • 20. GSM family evolution
  • 21. 4G Access Options
    Embed 4G technology into all end-user devices
    Develop mobile personal gateways
    Develop external interfaces with 4G peripherals
  • 22. Features
    • Wireless Internet with a bandwidth much wider than the 2G or 3G networks - 100 MHz
    • 23. Significantly increased the speed of data transmission - up to Gbps 1st
    • 24. Calls video conference - with more than 2 speakers, and because the flow of data faster will be less problems, not so often as to break with the 3G.
    • 25. The enhanced security features to prevent fraud and theft.
    • 26. The larger bandwidth for data sharing are relatively inexpensive
  • advantages
    • In a fourth-generation wireless system, cellular providers have the opportunity to offer data access to a wide variety of devices.
    • 27. The cellular network would become a data network on which cellular phones could operate โ€” as well as any other data device.
    • 28. Personal Media Repository:- Create a personal media repository that can be accessed from home and on the road to view photos, watch movies and listen to your personal music collection.
    • 29. Broadband Access in Remote Locations :- In addition, 4G will provide the first opportunity for broadband access in remote locations without an infrastructure to support cable or DSL access.
  • disadvantages
    Just as 3G technology started in major cities and to creep out into the suburbs and countryside slowly, 4G technology is currently found mainly in highly populated areas. If you're interested in this technology and want to use it for traveling, you might find that you can't take it as many places as you would like, as of yet. You'll simply run out of signal before you get where you're going.
  • 30. application
    The "killer application" is simply to have mobile always on internet
    4G should be able to provide users with streaming high-definition television.
    The content of a DVD, for example a movie, can be downloaded within about 5 minutes for offline access.
    Though the improved bandwidths and data throughput offered by 4g networks should provide opportunities for previously impossible products and services to be released.
