    • UMTS (Universal Mobile Telecommunication System) is the third generation telecommunications system based on WCDMA. WCDMA (Wideband Code Division Multiple Access) is the radio interface for UMTS. WCDMA is characterised by use of a wider band than CDMA. It has additional advantages of high transfer rate, and increased system capacity and communication quality by statistical multiplexing, etc. WCDMA efficiently utilises the radio spectrum to provide a maximum data rate of 2 Mbit/s. UMTS (Universal Mobile Telecommunication System) will offer a consistent set of services to mobile computer and phone users no matter where they are located in the world. Based on the GSM (Global System for Mobile communication) communication standard, UMTS, endorsed by major standards bodies and manufacturers, is the planned standard for mobile users around the world by 2002. Today's cellular telephone systems are mainly circuit-switched, with connections always dependent on circuit availability. Packet-switched connection, using the Internet Protocol (IP), means that a virtual connection is always available to any other end point in the network. It will also make it possible to provide new services, such as alternative billing methods (pay-per-bit, pay-per-session, flat rate, asymmetric bandwidth, and others). The higher bandwidth of UMTS also promises new services, such as video conferencing and promises to realise the Virtual Home Environment (VHE) in which a roaming user can have the same services to which the user is accustomed when at home or in the office, through a combination of transparent terrestrial and satellite connections. * Provides an introduction to cellular networks and digital communications * Covers the air interface, radio access network and core network * Explains the Release '99 specifications clearly and effectively * Discusses UMTS services and future services beyond 3G * Features numerous problems and solutions in order to aid understanding Ideal for Academics and students on telecommunications, electronics and computer science courses, research and development engineers working in mobile/wireless communications and Cellular operators and technical consultants.
  • Kurztext
    • Knowledge of the concepts, architecture, protocols and performance of UMTS is essential for all those working in the field of mobile communications. UMTS - The Fundamentals provides a clear understanding of the major concepts and their impacts on the rollout, operation, usability and capabilities of this innovative third generation system. All of the major radio, protocols and networking related functions of UMTS are presented and in addition, the service architecture, standards and the path towards next generation systems are described. * Provides an instructive approach allowing individuals unfamiliar with mobile radio systems to follow and understand UMTS. * Covers and clearly describes the entire field of 3G systems ranging from digital radio transmission, cellular basics, standardization, UMTS system architecture and protocols, service architecture, and an introduction to beyond 3G systems. * Features numerous problems and solutions to explain UMTS related subjects. Written in an easy to understand manner, this volume is the authoritative text for undergraduate and graduate students, practising engineers and for continuous education in industrial com panies, consultancy firms and public service organisations.
