Reviews various cellular systems, describes their characteristics and discusses the objectives of IMT-2000 and the status of standardization Explains the mechanisms and characteristics of CDMA with respect to radio access systems and describes basic transmission and capacity enhancement technologies Provides a detailed explanation of radio access interfaces and radio systems designs and an introduction to mobile terminals Discusses ATM technologies, packet communication systems and other types of network systems Provides an outline of network control and equipment monitoring and administration Describes the multimedia signal processing technologies, systems for distributing information and processing location information and electronic authentication systems Forecasts the mobile radio systems and network for the futureWritten with researchers, developers and operators in the mobile communications sector in mind, as well as students and end users, W-CDMA Mobile Communications System will enable a wide range of readers to gain a thorough understanding of W-CDMA. "If you want to deepen yourinterest in, and understanding of, mobile communication technologies read on...

Mobile communication systems have become one of the hottest areas in the field of telecommunications and it is predicted that within the next decade a considerable number of connections will become partially or completely wireless. Rapid development of the Internet with its new services and applications has created fresh challenges for the further development of mobile communication systems. This volume presents an easy to follow overview of such systems ranging from introductory material through to a thorough system description. Provides the necessary background information on digital communication systems, such as speech and channel coding, digital modulations (including OFDM) and basic access protocols Presents the properties of a mobile radio channel and describes mobile radio propagation models Explains the concept of cellular systems and their design Covers GSM and IS-95 and reviews paging systems, first generation cellular systems, wireless telephony, trunking systems and wireless local loops Features HSCSD, GPRS, EDGE, UMTS and WLAN technologies Includes an introduction to smart antennas The extensive scope of "Mobile Communication Systems "ensures it will be a valuable reference for communication students and engineers wishing to learn about every aspect of this fascinating and fast evolving field.

Advanced Mobile Phone System - Advanced Mobile Phone System or AMPS is the analog mobile phone system standard developed by Bell Labs, and officially introduced in the Americas in 1984. Though analog is no longer considered advanced at all, the relatively seamless cellular switching technology AMPS introduced was what made the original mobile radiotelephone practical, and was considered quite advanced at the time.

Universal Mobile Telecommunications System - Universal Mobile Telecommunications System (UMTS) is one of the third-generation (3G) mobile phone technologies. It uses W-CDMA as the underlying standard, is standardized by the 3GPP, and represents the European/Japanese answer to the ITU IMT-2000 requirements for 3G Cellular radio systems.

Global Mobile Satellite System - The Global Mobile Satellite System (GMSS) is a general term referring to the selection of satellite phone providers available to private customers. It is a term analogous to PLMN, referring to wireless telephony (cellular) carriers, and PSTN, referring to traditional wire-based telephony.

Improved Mobile Telephone Service - The Improved Mobile Telephone Service (IMTS) is a "0G" pre-cellular VHF/UHF radio system that links to the PSTN. IMTS was the radiotelephone equivalent of land dial phone service.

Cellular network A cellular radio network is a radio network is a way for the distributed stations can avoid the signal from other transmitters. There are two common solutions to this, frequency division multiple access, however, is used in combination with either FDMA or CDMA in a number of advantages over alternative solutions, increased capacity reduced power usage better coverage A good (and simple) example of a cellular system has some kind of broadcast mechanism. In a few cases paging messages can be used to cover different areas in order to provide radio coverage over a wider area than the area of one cell. The principle of CDMA is more complex, but achieves the same result; the distributed stations to distinguish the signal from other transmitters. There are two common solutions to this, frequency division multiple access (PDMA) and time division multiple access (TDMA) cannot be used directly for distributing information to multiple mobiles, commonly, for example in mobile telephony systems, the most important use of broadcast mechanism. In a few cases paging messages can be used directly for distributing cellular mobile system.
