This book is a practical guide to the life cycle of a WCDMA/UMTS cellular network deployment, offering network planners and optimization engineers a single reference to their day-to-day tasks. After introducing the network architecture of such a system, the authors define the coverage and capacity concepts associated with the dimensioning and design phases. From there, the book progresses to discuss the main system parameters associated with network optimization. The authors also detail optimization techniques for the important services supported by UMTS, including specifics about how to deploy HSDPA networks successfully. The text is heavily illustrated with tables, line drawings, graphs, and screen shots of network planning predictions.
