4G is the fourth generation of cellular wireless standards that will provide extremely high bandwidth for mobile internet use. It aims to offer significantly higher maximum data speeds and capacity compared to 3G networks, allowing uninterrupted high-quality video calls and multimedia messaging. Key attributes of 4G include support for multiple applications and services simultaneously, high quality of service, seamless handover between networks, and technology and topology independence. 4G will integrate capabilities with existing 2G and 3G systems and digital broadcasting to achieve "Always Best Connected" connectivity.

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

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

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

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

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.
