4G is the next generation of mobile networks projected to be deployed around 2010. It will provide speeds up to 100 Mbps for mobile users and 1 Gbps for stationary users. 4G will use new technologies like OFDM and MIMO for faster speeds and lower latency. It will allow for real-time mobile video calling and convergence of wireless and fixed networks through an all-IP infrastructure. 4G aims to provide broadband internet access to various devices anywhere through an always-on cellular network.

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.

27. The cellular network would become a data network on which cellular phones could operate — 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.

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.
