In telecommunications, 4G is the fourth generation of cell phone mobile communications standards. Hence, LTE (Long Term Evolution) and WiMAX (Worldwide interoperability for Microwave Access) became the two leading technologies. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. Battle between LTE and WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards through IEEE 802.16 and is up and running but lacks in substantial roll out plans due to cost. On the other hand, new applications required to be supported by new mobile systems include a variety; VoIP, video conference, multimedia messaging, multiplayer games, Virtual Private Network (VPN), etc.
