Mobile Communication has been developed rapidly since last few decades. The growth of the wireless broadband technologies in the modern years was the answer of increasing demand for mobile Internet and wireless multimedia application such as live TV, live Movies, video conferencing etc. Mobile communication plays a vital role in telecommunication industry. During a common wide area radio access technology and supple network architecture WiMAX and LTE has facilitate convergence of mobile and fixed broadband network. Since 2007, the IEEE 802.16 working group has been developing a new improvement if the IEEE 802.16 standards as a higher level air interface to meet the requirement of ITU-R/IMT-advanced for 4G system as well as for the next generation. In 4G mobile technology, assures the high mobility with high level speed of data rates and high capacity IP based services and application. This paper describes the 4G wireless system, its architecture, security services, benefits and challenges of 4G wireless technology.
WiMAX, LTE (Long Time Evolution), OFDMA (Orthogonal Frequency Division Multiplex Access), MIMO (Multiple Input Multiple Output), MME (Mobility Management Entity)
