Description: UMTS (Universal Mobile Telecommunication System) is the third generation telecommunications system based on WCDM a. WCDM a (Wideband Code Division Multiple Access) is the radio interface for UMTS. WCDM a is characterised by use of a wider band than CDM a. It has additional advantages of high transfer rate and increased system capacity and communication quality by statistical multiplexing etc. WCDM a 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 3 G * 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.
