"WCDMA for UMTS" provides a complete picture of the Wideband CDMA (Code Division Multiple Access) air interface of the 3rd generation cellular systems - UMTS (Universal Mobile Telecommunications Systems). "WCDMA" is designed for multimedia communications including high quality images and video, and access to services with high data rates. These capabilities will create new business opportunities for manufacturers, operators and for the providers of content and applications. The key features: explains the key parts of the WCDMA standard and provides guidelines for its efficient use; presents network dimensioning and coverage and capacity planning of WCDMA; introduces radio resource management algorithms in the WCDMA network; examines the coverage and capacity of WCDMA up to 2Mbps using numerous simulation results; introduces the TDD (Time Divisions Duplex) mode; and discusses the co-existence of TDD and FDD (Frequency Divisions Duplex) and highlights their main differences. Now includes the main modifications made to the 3GPP standard up until the end of 2000 and features the following new material: Reference terminal classes, current status of UMTS licensing, capacity upgrade paths and capacity per km2, inter-frequency handovers and inter-system handovers to GSM, and antenna diversity gain measurements in the WCDMA experimental system. Written by leading experts in the field, this practical approach to the key features in WCDMA will have wide-ranging appeal to Research and Development Engineers, Practising Engineers, Cellular Operators, Technical Managers and Students on Telecommunications courses.
