Telecommunications and Data Communications Handbook provides a comprehensive survey of telecommunications and data communications technologies and services, their origins and evolution, and their meaningful contemporary applications. The evolution of the regulatory environment and its impacts on the carrier/service provider landscape form the concluding chapters. The book explores these subjects in reasonable technical depth, yet in a plain-English commonsense style. Important topics include: Voice over Internet Protocol (VoIP); 802.16 & WiMAX; Passive Optical Network (PON); 802.11g & Multiple Input Multiple Output (MIMO).
