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 formatsFundamental digital communication theory, leading modulation techniques, and basic mathematical tools for digital transmission analysisMicrowave propagation, the structure of microwave links, diversity techniques for improving reliability, and the computation of link availabilityOptimizing real-world performance: Reed-Solomon, Convolution and Turbo coding, Trellis coded modulation, adaptive equalization, cross-polarization interference cancellation, and automatic transmitter power controlPoint-to-point system design in licensed and unlicensed frequency bands, including the use of spread spectrum techniques such as Wi-Fi's CCK modulationLast-mile access via point-to-multipoint and mesh structured systems: TDD, FDD, TDMA, FDMA, CDMA, OFDM, OFDMA, MIMO, Adaptive BeamformingEmerging 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.
Fixed wireless Internet is access offered by local service providers as an alternative to copper- or cable-based high-speed access. Fixed wireless does not require satellite feeds, a government license, or even local phone services. These systems utilize a small, inexpensive microwave antenna that is attached to a radio at the customer premises. The Customer Premise Equipment (CPE) is pointed back to the ISPs Access Point (AP)--typically a tall building or radio tower--to create a Wireless Local Loop (WLL). As an unfamiliar, unknown, totally un-hyped form of broadband service, fixed wireless Internet access is distinctly different from the aforementioned wired services by its potential transport speed of and affordability--among other features. It's popularity because of this restriction free (telco free) feature is growing rapidly. Our book starts with a brief history of fixed wireless, current applications, and a summary of competitive technologies. It then moves on to the various forms of information transported by these systems and the fundamental technical structure of these systems. Both point-to-point and point-to-multipoint systems, operating in licensed as well as unlicensed bands are covered and emerging relevant standards introduced.
