Mobile communication systems revolutionized the way people communicate. Evolution of wirelessaccess technologies is about to reach its fourth generation (4G) and the 5G mobile networks will focus on thedevelopment of the user terminals where the terminals will have access to different wireless technologies atthe same time and will combine different flows from different technologies. Looking past, wireless accesstechnologies have followed different evolutionary paths aimed at unified target related to performance andefficiency in high mobile environment. The first generation (1G) has fulfilled the basic mobile voice, whilethe second generation (2G) has introduced capacity and coverage. This is followed by the third generation(3G), which has quest for data at higher speeds to open the gates for truly “mobile broadband” experience,which was further realized by the fourth generation (4G).The Fourth generation (4G) provides access to widerange of telecommunication services, including advanced mobile services, supported by mobile and fixednetworks, which are increasingly packet based, along with a support for low to high mobility applications andwide range of data rates, in accordance with service demands in multiuser environment. Fifth generationshould be more intelligent technology that interconnects the entire world. This article provides a high leveloverview of the Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access(WiMAX)-the leading technologies for next-generation mobile broadband.
