Wireless Technician’s Handbook

Andrew Miceli9781580533577, 1580533574

This second edition of the Artech House classic, Wireless Technician’s Handbook, applies up-to-date knowledge of wireless communications formats to the real-world situations professionals encounter every day. Featuring new material on such critical technologies as GPRS, EDGE, CDMA2000, and WCDMA, this single, easy-to-understand volume collects the latest information that is essential for working in the field today. Covering dBm versus watts, the differences between analog, TDMA, and CDMA, as well as the evolution to 2.5 and 3G standards such as EDGE, WCDMA, and CDMA2000, and the testing of handsets and base stations, this handy resource explains all first-tier wireless formats in clear, concise language. The book focuses on testing concepts and procedures and types of testing equipment, including spectrum analyzers and power meters and their applications. Moreover, it reviews AMPS, CDMA, IS-136, and GSM, and includes important charts and screen shots from common test instruments.
