Summary

The complete, friendly, non-technical introduction to wireless and RF technologies! The Essential Guide to RF and Wireless covers wireless and RF technologies at every level non-technical professionals need to understand, including fundamental concepts, basic terminology, components, system building blocks, and complete systems. Carl J. Weisman introduces each of today's hottest wireless technologies, including spread spectrum, wireless local loop, ISM, LMDS, CDMA -- as well as some of tomorrow's most promising standards. The book is remarkably accessible: written in a light, engaging tone, with extensive use of figures, photographs, and visual analogies proven to make wireless and RF technologies easier to understand. For anyone working in and around the wireless/RF industries who does not have an engineering degree or strong technical background.
