Opis

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.

O autorze

EMMANUEL DESURVIRE has been involved in optical telecommunications for nearly twenty years, starting with a PhD work on Raman fiber amplifiers at Thomson–CSF in 1983, followed by post–doctoral research at Stanford University. He then joined AT&T Bell Laboratories for five years, where he led the early investigation and development of erbium–doped fiber amplifiers (EDFA). For his pioneering contributions to EDFAs, he received several national and international awards including the 1994 Prize from the International Commission for Optics and the 1998 Benjamin Franklin Medal in engineering. After a two–year professorship at Columbia University, he joined Alcatel where he conducted research on long–haul soliton transmission and all–optical regeneration, then 40Gbit/s systems development. He also created and directed a corporate program to foster synergies between experts and promote innovation. An IEEE Fellow, he has authored or coauthored more than 200 technical publications, four books, and over thirty patents.

A survival guide to global telecommunication technologies

As our world grows ever more complex, no one can expect to be knowledgeable in, let alone master every technology. But as telecommunications technologies permeate nearly every aspect of our lives, gaining a working understanding of their principles and applications has become essential for both professional and personal success. For the undergraduate student preparing for his or her future vocation to the accomplished professional on track for a rapid career move, this book is the "survival guide" to telecommunications a quick introduction to the most important telecom technologies. Written with accuracy and rigor, this guide avoids any unnecessary background or academic style in order to introduce you directly to the core knowledge and understanding.

Wiley Survival Guide in Global Telecommunications: Signaling Principles, Network Protocols, and Wireless Systems provides in–depth discussions of key areas in telecommunications, including:

• Signal modulation, coding, transmission, detection, and error correction
• Telephony and data networking, from PSTN to packet–switched/LAN protocols and ISDN
• Core–network transmission protocols (SONET/SDH, ATM, TCP/IP, and Internet suite)
• Wireless communications (3G/4G mobile, satellite, and WLAN)

Designed to be accessible to a wide range of readers, the book steers you directly into the relevant issues, while elucidating the science and engineering involved without heavy–duty mathematics, allowing you to produce results using your pocket calculator. You can read each chapter in sequence or, if you prefer, jump to topics of interest as you wish. A wealth of easy and practical exercises illustrate the concepts; chapter–end summaries of main keywords and acronyms clarify the technical language; and a selected reference list including Web sites leads you to other helpful sources for further investigation.

Arm yourself with the knowledge you need to survive in the telecom world with this indispensible guide.
