Overview

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.
