Description
This new 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 you encounter everyday. Featuring brand new material on such critical technologies as GPRS, EDGE, CDMA-2000, and WCDMA, this single, easy-to-understand volume collects the comprehensive information that is essential for your work 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 CDMA-2000, and testing of handsets and base stations, this handy resource explains all first-tier wireless formats in clear, concise language, helping you to become more knowledgeable and productive. 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. An invaluable reference for the field-based technician, the book also serves as an excellent guide for non-technical wireless professionals.
