Condizione: Muy bueno. : Este libro ofrece una descripción completa y detallada de los sistemas de radio móvil e inalámbricos digitales, centrándose específicamente en las funciones orientadas a la red de todos los sistemas existentes o planificados para el futuro cercano. Basándose en la propia experiencia académica e industrial del autor en el campo, se presta especial atención a los detalles relacionados con la radio necesarios para el establecimiento de un sistema de comunicación móvil que es mucho más complejo que una red cableada. Todos los sistemas descritos se han implementado durante la investigación para el análisis de su rendimiento mediante simulación estocástica impulsada por eventos bajo cargas de tráfico típicas. En consecuencia, las similitudes y diferencias entre los sistemas se describen de forma clara y coherente. Este es un estudio práctico y detallado de un campo de rápido movimiento que evita enfoques teóricos innecesarios para garantizar la claridad de los hechos presentados para los ingenieros de la industria, así como para los estudiantes de comunicaciones móviles.

Hardcover. Condizione: new. Hardcover. Presents the model and methodology, applied by ITU-R WRC07, to calculate the spectrum requirement Spectrum Requirement Planning in Wireless Communications: Model and Methodology for IMT-Advanced is a self-contained handbook of the models and methodologies used for the spectrum requirement calculation for IMT-Advanced systems, as well as for the predecessor IMT-2000 systems. The reader will learn how the spectrum requirement is calculated for real systems that prevail worldwide. The book also provides the basis on which to develop advanced methodologies for yet future systems, as the spectrum regulation will continue in the future. Spectrum Requirement Planning in Wireless Communications: Model and Methodology for IMT-Advanced Provides the reader with information on how the spectrum requirement is calculated for real systems that prevail worldwideContains useful tables and examples such as flowchart of the methodologyIntroduces definitions of service category and radio environment, the process of distributing traffic to radio environments, and the method to calculate the required spectrumApplies queueing and loss models for the calculation of required system capacityCovers utilization of radio frequencies, market data, spectrum requirement calculation methods for IMT-2000 and for IMT-Advanced systemsInstructs how to use the calculation tool package Comes with an accompanying website with the downloadable tool applied by ITU-R WRC07 for making decisions on spectrum regulation for mobile systems This book serves as an invaluable guide to engineers in mobile phone companies, system design engineers, operator system engineers and other specialists dealing with mobile system planning and development. It is also of great interest to researchers and graduate students in the fields of applied probability theory, operations research, telecommunications, and mobile networks engineering.

Condizione: Gut. Zustand: Gut | Seiten: 1176 | Sprache: Englisch | Produktart: Bücher | Building on the success of the first edition Mobile Radio Networks continues to be the authoritative text on the radio-related and network-oriented functions of the digital communications networks that have been introduced over the last few years. Thoroughly revised and updated, containing 30% new material, the second edition has been substantially improved and now provides detailed descriptions of the latest wireless systems designs. The traffic performance behaviour of all systems under realistic traffic load conditions is presented and comparisons are made with the performance seen by the user of various competing systems. * Features new chapters on GSM/GPRS/EDGE systems and includes their traffic performances * Presents completely new material on 3G systems, focussing on UMTS radio access and fixed network, and a comparison of spectrum efficiency of UMTS and EDGE * Details the Virtual Home Environment architecture of UMTS, SAT and MExE * Includes revised and substantially expanded chapters on Wireless LANs and a performance comparison of IEEE 802.11a and HiperLAN/2 * Offers new sections on ad hoc W-LANs, Bluetooth, WAP and WML and new material on next generation systems * Contains detailed descriptions of numerous systems including DECT, PHS, TETRA, PDC, IS-95 and mobile satellite Engineers and researchers will continue to find this all-encompassing treatment of mobile radio networks a valuable resource and it will also provide an extensive reference for postgraduates and students in mobile communications.

Hardback. Condizione: New. 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.
