A Technical Comparison of Mobile WiMAX and Third Generation Mobile Technologies

Abstract

Mobile WiMAX, as a fourth generation technology, meets all the requirements for Personal Broadband access. It supports high data rates,
high sector throughput, multiple handoff mechanisms, power-saving mechanisms for mobile devices, advanced QoS and low latency for improved
support of real-time applications, advanced authorization, authentication and accounting (AAA) functionality.
Unlike the CDMA-based 3G systems, which have evolved from voice-centric systems, WiMAX is designed to meet the requirements necessary for the
delivery of broadband data services as well as voice. UMTS, CDMA2000 and TD-SCDMA are all optimized for voice applications (with the obvious
exception of EV-DO). These technologies have evolved over 7-10 years and data / broadband has been added to the standard incrementally.
