The Definitive Guide to Wi MAX Technology Wi MAX is the most promising new technology for broadband wireless access to IP services. It can serve an extraordinary range of applications and environments: data, voice, and multimedia; fixed and mobile; licensed and unlicensed. However, until now, wireless professionals have had little reliable information to guide them. Fundamentals of Wi MAX is the first comprehensive guide to Wi MAX-its technical foundations, features, and performance. Three leading wireless experts systematically cut through the hype surrounding Wi MAX and illuminate the realities. They combine complete information for wireless professionals and basic, accessible knowledge for non-experts. Professionals will especially appreciate their detailed discussion of the performance of Wi MAX based on comprehensive link- and system-level simulations. Whether you’re a wireless engineer, network architect, manager, or system designer, this book delivers essential information for succeeding with Wi MAX-from planning through deployment. Topics include Applications, history, spectrum options, technical and business challenges, and competitive technologies of Wi MAX 802.16 standards: physical and MAC layers, channel access, scheduling services, mobility, advanced antenna features, hybrid-ARQ, and more Broadband wireless channels: pathloss, shadowing, cellular systems, sectoring, and fading-including modeling and mitigation OFDM: from basic multicarrier concepts to synchronization, PAR reduction, and clipping MIMO: Multiple antennas, spatial diversity, beamforming, and a cutting-edge treatment of the use of MIMO in Wi MAX OFDMA: multiple access, multiuser diversity, adaptive modulation, and resource allocation Networking and services aspects: architecture and protocols for IP Qo S, session management, ecurity, and mobility management Predicting performance using link-level and system-level simulations Wi MAX network architecture: design principles, reference models, authentication, Qo S, and mobility management
