Fixed broadband wireless: New multi-megabit "long-haul" to "last mile" solutions

Fixed broadband wireless systems give service providers and enterprises flexible, cost-effective ways to deliver, from "long-haul" to "last-mile", voice and Internet/data services at multi-megabit rates. Now, wireless infrastructure consultant Dr. Douglas Morais systematically introduces, with the aid of insightful examples, fixed broadband wireless for working professionals: its principles, design techniques, emerging standards, practical applications, and state-of-the-art commercial systems. Coverage includes:

• Circuit-switched (PDH and SONET/SDH) and packet-switched (IP, ATM, Ethernet) signal formats
• Fundamental digital communication theory, leading modulation techniques, and basic mathematical tools for digital transmission analysis
• Microwave propagation, the structure of microwave links, diversity techniques for improving reliability, and the computation of link availability
• Optimizing real-world performance: Reed-Solomon, Convolution and Turbo coding, Trellis coded modulation, adaptive equalization, cross-polarization interference cancellation, and automatic transmitter power control
• Point-to-point system design in licensed and unlicensed frequency bands, including the use of spread spectrum techniques such as Wi-Fi's CCK modulation
• Last-mile access via point-to-multipoint and mesh structured systems: TDD, FDD, TDMA, FDMA, CDMA, OFDM, OFDMA, MIMO, Adaptive Beamforming
• Emerging standards such as WiMAX supported 802.16/16a and HIPERMAN

Whether you're involved in planning, assessing, designing, marketing or building fixed broadband wireless infrastructure, this book will help you understand the basic issues and factors affecting performance and reliability.
