  • 2. 4G
    Generation of cellular wireless
    4G
    3G
    2G
    1G
  • 3. 3G
    1G & 2G
    4G
    - Extremely high available bandwidth
    - High-speed data access and video
    Conferencing
    - Worldwide roaming
    using a single handheld device.
    FEATURES
  • 4. An overview of 1G, 2G, 3G
    • First-generation of wireless telephone technology, mobile telecommunications
    • 5. Telecommunications standards that were introduced in the 1980s
    • 6. Uses digital signaling to connect the radio towers to the rest of the telephone system
    • 7. launched on the GSM standard in Finland by Radiolinja in 1991
    • 8. Phone conversations were digitally encrypted
    • 9. Lower power emissions helped address health concerns.
    • 10. Lower powered radio signals require less battery power
    • 11. All-digital allowed for the introduction of digital data services, such as SMS and email.
    • 12. Enhanced privacy
    • 13. 3rd Gene is a family of standards for mobile telecommunications
    • 14. The first pre-commercial 3G network was launched by NTT DoCoMo in Japan
    • 15. 3G networks offer a greater degree of security than 2G predecessors
    • 16. Services include
    -wide-area wireless voice telephone,
    • video calls
    • 17. wireless data
    3G
    1G
    2G
  • 18. Comparison of 1G&2G
    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
    In comparison to 1G’s analog signal, 2G’s analog signal are very reliant on location and distance.
    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
  • 19. 4G
    The term 4G is used broadly to include several type of broad band, wireless access communication systems, not only cellular telephone systems.
    The new generation of wireless is intended to compliment and replace the 3G system.
    4G can also be defined as “MAGIC”
    M- Mobile Multimedia
    A-Anytime Anywhere
    G-Global Mobility Support
    I-Integrated Wireless Solution
    C-Customized personal service
  • 20.
  • 21. 8
    4G an overview
    2G – 2nd Generation Mobile System
    GSM, IS-95, cdmaOne
    Low-bit-rate data
    3G – 3rd Generation Mobile System
    Higher-data-rate service
    New technology
    GPRS
    IMT-2000
    Bluetooth
    WLAN
    HiperLAN
    Independent systems, all have there own shortcomings
    A single system is needed to replace all of them – 4G
  • 22. 4G-Features
    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.
    The 4G systems, will inter-operate with the 2G and 3G systems as well as with, digital broadcasting system.
    The key concept is integrating the 4G capabilities with all of the existing mobile technologies through advanced technologies.
  • 23. Key attributes of 4G
  • 24. Support for Multiple Applications and Services
    • Efficient support for unicast, multicast and broadcast services and the applications that rely on them.
    Quality of Service
    Consistent application of admission control and scheduling algorithms regardless of underlying infrastructure and operator diversity.
  • 25. Network Detection and Network Selection
    A mobile terminal that features multiple radio technologies or possibly uses software defined radios if economical, allows participation in multiple networks simultaneously
    Seamless Handover and Service Continuity
    Support for this function requires continuous transparent maintenance of active service instances and inclusion of various access technologies, from WiFi
  • 26. Technology and Topology Independence
    Services not constrained by topology or technology limitations, but rather achieve the “Always Best Connected” characteristic.
    Conclusion
    It is inevitable that 4G would completely replace 3G in long run.
    In order for 4G to grow on the future market, it is unavoidable to compute with 3G and acquire 3G’s customer.
