WiMAX versus LTE - An overview of technical aspects for next generation networks technologies

In the last few years, we have witnessed an explosion of IP connectivity demand, translated into a rapid development of the corresponding technologies in the wireless access network domain. IP services provision anytime and anywhere becomes very challenging and is seen by the mobile operators as a major opportunity for boosting the average revenue per unit. The further success of IP services deployment requires true mobile broadband IP connectivity on a global scale. For accomplishing this request, two technologies emerged with the aim of providing voice, data, video and multimedia services on mobile devices at high speeds and cheap rates: WiMAX (Worldwide Interoperability for Microwave Access) and LTE (3GPP Long Term Evolution). This paper investigates LTE and WiMAX technologies in terms of architectural benefits, user and operator acceptance and first two layers performances. It is concluded that these technologies will play an equally important role in the future of wireless networks.
