Executive Summary

WIMAX, the world wide interoperability for microwave access, is a technology which provides wireless transmission of data in variety of ways, ranging from point to point links to the full mobile cellular access. The WIMAX physical layer is based on orthogonal freq division multiplexing a scheme that offers good resistance to multipath, and allows WIMAX to operate in NLOS conditions; MOBILE WIMAX uses OFDM as a multiple access technique, whereby different users can be allocated different subsets of the OFDM tones. OFDMA facilitates the exploitation of frequency diversity and multiuser diversity to significantly improve the system capacity.
