Abstract
The term WiMAX is an abbreviation of Worldwide Interoperability for Microwave Access and it is defined in IEEE, as the 802.16 family of standards. Unlike other legacy Point-to-Multipoint wireless technologies, WiMAX is able to offer higher transmission rates, quality of service assurance and hence it can be compared to other wireline technologies. Additionally, WiMAX is proven to be useful for telemedicine purposes (live surgeries and medical examinations, medical conferences etc.), especially in distant areas. WiMAX is based on two major standards; one is the IEEE802.16d that was developed specifically for fixed wireless communications and is dedicated mainly in LOS environments and can be used in many cases, where fixed infrastructure is not available. On the other hand, 802.16e can be used in cases of both fixed and moving subscribers, while providing better coverage, performance and even higher transmission rates. This chapter describes the major capabilities of the WiMAX standard and presents the performance of WiMAX networks based on measurements taken during laboratory and field tests.
