A Coherent Systems View of Wireless and Cellular Network Design and ImplementationWritten for senior-level undergraduates, first-year graduate students, and junior technical professionals, Introduction to Wireless Systems offers a coherent systems view of the crucial lower layers of today’s cellular systems. The authors introduce today’s most important propagation issues, modulation techniques, and access schemes, illuminating theory with real-world examples from modern cellular systems. They demonstrate how elements within today’s wireless systems interrelate, clarify the trade-offs associated with delivering high-quality service at acceptable cost, and demonstrate how systems are designed and implemented by teams of complementary specialists.Coverage includesUnderstanding the challenge of moving information wirelessly between two pointsExplaining how system and subsystem designers work together to analyze, plan, and implement optimized wireless systemsDesigning for quality reception: using the free-space range equation, and accounting for thermal noiseUnderstanding terrestrial channels and their impairments, including shadowing and multipath receptionReusing frequencies to provide service over wide areas to large subscriber basesUsing modulation: frequency efficiency, power efficiency, BER, bandwidth, adjacent-channel interference, and spread-spectrum modulationImplementing multiple access methods, including FDMA, TDMA, and CDMADesigning systems for today’s most common forms of traffic—both “bursty” and “streaming”Maximizing capacity via linear predictive coding and other speech compression techniquesSetting up connections that support reliable communication among usersIntroduction to Wireless Systems brings together the theoretical and practical knowledge readers need to participate effectively in the planning, design, or implementation of virtually any wireless system.
