The development of broadband wireless access technologies in recent years was the result of growing demand for mobile Internet and wireless multimedia applications. Mobile communication plays a most important role in telecommunications industry. Through a common wide-area radio-access technology and flexible network architecture WiMAX and LTE has enabled convergence of mobile and fixed broadband networks. Since January 2007, the IEEE 802.16 Working Group has been developing a new amendment of the IEEE802.16 standard (i.e., IEEE 802.16m) as an advanced air interface to meet the requirements of ITU-R/IMT-advanced for 4G systems as well as for the next-generation mobile network operators. Next fourth generation (4G) mobile technology, promises the full mobility with high speed data rates and high-capacity IP-based services and applications while maintaining full backward compatibility. This paper explores 4G wireless system, its features and technologies to fulfill its requirement.
