Wireless Spectrum Finder

"Wireless Spectrum Finder maps out that prime expanse of virtual real estate, the public airwaves. These are the frequency bands used for all wireless communications from TV broadcasts to cellular phones, wireless Internet to spy satellites, and the many new applications agleam in developers' eyes. Yet information on the properties, availability, and regulation of key radio bands is hard to find - and often hard to interpret once found." "You know that spectrum planning is a vastly complicated, high-stakes occupation. If it's yours, life just got easier." --Book Jacket.

AN UNCONVENTIONAL, FUN WAY TO MASTER THE BASICS OF CRYPTOGRAPHY Cryptography is not just for specialists. Now every wireless message, wireless phone call, online transaction, and email is encrypted at one end and decrypted at the other. “Crypto” is part of the job description for network designers, network engineers, and telecom developers. If you need cryptography basics—but dread the thick tomes that are your only other option—help is at hand. Cryptography Demystified puts the fundamentals into a 35-module, learn-by-doing package that’s actually fun to use. You must read this book if— * You prefer your simplifications from an expert who understands the complexities * 6 years of success as a short course for students and professionals works for you * you enjoy hearing the phrase “nothing to memorize” * ecommerce, email, network security, or wireless communications is part of your bailiwick * cracking cryptography means a jump up the career ladder * the words “public-key cryptography,” “channel-based cryptography,” and “prime numbers” pique your interest * best-practices cryptography is the only secure way for you—and your company—to go One of the most complex subjects in Information Technology, cryptography gets its due in this down-to-earth, self-teaching tutorial—the first to make the basics of the science truly accessible.

Keeping up to date with the most current technologies in the field is essential for all effective electrical and computer engineers. The updated 7th edition of Principles of Communications presents the reader with more in-chapter examples, providing for a more supportive framework for learning. Readers are exposed to digital data transmission techniques earlier in the book, so they can appreciate the characteristics of digital communication systems prior to learning about probability and stochastic processes. They will also find expanded forward error correction code examples, and additional MATLAB problems.

RF spectrum is the most valuable commodity in the wireless market the wireless equivalent of real estate.

An ever-increasing demand for the radio frequency (RF) spectrum is transforming current radio regulations at national and international levels at a fast pace. This book will introduce you to the science and policies behind the spectrum management and to the process that aims at maintaining the fair sharing of the spectrum among a huge gamma of applications for the benefit of society.

In the past 7 years CDMA (Code Division Multiplexed Access) has grown from a small experiment to the technology that is going to replace all existing wireless methods in North America and around the world, replacing even GSM, which up to now has been deeply entrenched in Europe and elsewhere. Though many books cover it conceptually, there are few that deal in the application of CDMA to the day-to-day functioning of the wireless network. This book is focused on the workplace needs of RF managers and engineers. Mathematically difficult material has been culled from the body of the book and placed in carefully organized appendices, so readers have access to derivations but don’t have to wade through them to find the solutions they’re looking for. And unlike any existing CDMA book, this details the similarities and differences between the 2G IS-95 and 3G IS-2000 standards, focusing on the many issues that changeover is going face.
