WiMAX is a wireless technology that potentially replaces all forms of telecommunications access. It can replace the telephone company's copper wires to a home or business. It can replace the cable TV company's coaxial cable to the home. It can replace the cell phone company's wireless networks. It can even replace fiber optic cables. Relative to all those technologies, WiMAX is not very expensive and complements IMS (IP multimedia subsystems), IPTV, VoIP. This book delves into that as well as MIMO, SDR, Adaptive Antenna Systems (AAS), interference mitigation, link budget, attenuation, site survey, IEEE802.16-2004, IEEE 802.16e, Quality of Service (QoS), security, availability, OFDM, OFDMA, MAC layer, PHY layer, spectral efficiency, OPEX, CAPEX, MTBF, licensed spectrum, space time coding (STC), beam forming, AES, encryption. This highly focused book provides what you really need to know in 50 pages.
