Wireless technologies have been adopted into the field of communication in the recent past. The fast pace in the growth of advanced wireless hardware and technologies have caused the evolution and generation of five wireless communication standards within this short span of time. The Fourth Generation (4G) communication standard, which is the most recent of these five, is a promising area for research. 4G systems aim at implementing a global communication network by integrating all existing telecommunication standards. It modifies the main goal of wireless communication from "Always connected" to "Always best connected".
