This book contains information that helps you understand the telecom industry better. Wireless Communications: Principles and Practice by Theodore Rappaport is a comprehensive study of the most important standards associated with cellular, cordless telephone and personal communication systems. The book expands on the functionality of these products and briefs readers regarding AMPS, U.S. Digital Cellular, CT-2, GSM, CDMA, DECT, WACS, ETACS, PDC and CDPD. The processes involved in the working of these items have been clearly defined by way of numerous diagrams, data tables and figures in the book. These help in a more practical approach to the concepts, along with the theoretical aspects. Introduction to topics such as mobile radio communication system, the cellular concept, radio wave propagation, equalization, diversity and channel coding provide the reader with a fair understanding of the wireless networks in place. The appendices at the end explain several things as well like the Trunking Theory and Gaussian Approximation, also listing down acronyms and abbreviations along with mathematical tables, functions and transforms. The second edition of Wireless Communications: Principles and Practice was published by Pearson Education in 2010 and is available in paperback.
