The development is seen towards the user terminals as a focus of the 5G mobile networks.
The 5G terminals will have software defined radios and modulation scheme as well as new error-control schemes can be downloaded from the Internet on the run. In the proposed concept the mobile user is on the top of all. The main contribution of this paper is definition of 5G (Fifth Generation) mobile network concept which is seen as user-centric concept instead of operator-centric as in 3G or service-centric concept as seen for 4G. Then, the concepts of 4G is already much discussed and it is almost certain that 4G will include several standards under a common umbrella, similarly to3G, but with IEEE 802.xx wireless mobile networks included from the beginning. On the other side, there are many wireless technologies that have proven to be important, with the most important ones being 802.11Wireless Local Area Networks (WLAN) and 802.16 Wireless Metropolitan Area Networks (WMAN), as well as ad-hoc Wireless Personal Area Network (WPAN) and wireless networks for digital TV and radio broadcast. Today 3G mobile systems are on the ground providing IP connectivity for real-time and non-real-time services.
