ABSTRACT

IEEE 802.16 is a set of telecommunications technology standards aimed at providing wireless access over long distances in a variety of ways-from point-to-point links to full mobile cellular type access as shown in Figure 8.1. It covers a metropolitan area of several kilometers and is also called WirelessMAN. Theoretically, a worldwide interoperability for microwave access (WiMAX) base station (BS) can provide broadband wireless access (BWA) in the range of up to 30 miles (50 km) for fixed stations and 3-10 miles (5-15 km) for MSs with a maximum data rate of up to 70 Mbps [1,2], as compared to 802.11a with 54 Mbps to several hundreds of meters, enhanced data rates for global evolution (EDGE) with 384 kbps to a few kilometers, or code-division multiple access 2000 (CDMA2000) with 2 Mbps to a few kilometers.
