Informationen zum Autor Bernhard H. Walke is a pioneer of mobile Internet access and professor emeritus at RWTH Aachen University in Germany. He is a driver of wireless and mobile 2G to 5G cellular radio networks technologies. Klappentext 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. Zusammenfassung Offers a comprehensive description of services and protocols of the mobile radio networks. This book pays particular attention to the radio-related specifics required for establishment of a mobile communication system. It includes chapter on GPRS/EDGE and performance evaluation results of EDGE and UMTS.
