WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless. 2G: Based on Digital Technology (Elliott, Phillips, 2004 ). 1G, lack of security and the proliferation of different wireless network standards; 2G occurred in early 1990s; GSM (Global System for Mobile Communication).

Evolution to cellular networks – communication anytime, anywhere. radio communication was invented by Nikola Tesla and Guglielmo Marconi: in 1893, Nikola Tesla made the first public demonstration of wireless (radio) telegraphy; Guglielmo Marconi conducted long ditance (over see) telegraphy. In this paper we propose novel network architecture for next generation 5G mobile networks. The proposed architecture is based on user-centric mobile concept in heterogeneous wireless environment. The implementation of the proposed architecture is performed in the service stratum, while the radio access technologies.
