Wiley Survival Guide in Global Telecommunications: Signaling Principles, Protocols, and Wireless Systems provides a rapid introduction to the whole field of telecom technologies and will provide a consistent starting point for further study for the diverse set of interested populations, which the author differentiates into the following five categories: the rare telecom generalists, who can conceptually grasp the full picture; the greater number of individuals who are technical contributors, scientists, and engineers who concentrate on top--level applications; the majority of end users and consumers, professionals and private; the population of some underdeveloped countries who rarely or never use any of these technologies. The book provides a comprehensive approach to telecom accessible to a broad audience. Each chapter concludes with a summary and exercises with solutions in some cases. Advanced equations requiring math background to appear only in the Appendix, and references are limited to books and review papers deemed accessible to the book's intended broad audience.
