With around 3 billion subscribers, GSM is the world's most commonly used technology for wireless communication. Providing an overview of the innovations that have fuelled this phenomena, GSM: Architecture, Protocols and Services, Third Edition offers a clear introduction to the field of cellular systems. Special emphasis is placed on system architecture and protocol aspects, and topics range from addressing concepts through mobility management to network management. This third edition contains around 25% new and reworked material and has been thoroughly updated to encompass recent advances and future trends. It serves as both an introductory textbook for graduate students as well as a reference resource for telecommunications engineers and researchers.This edition: Presents capacity enhancement methods like sectorization, the application of adaptive antennas for Spatial Filtering for Interference Reduction (SFIR) and Space Division Multiple Access (SDMA)Provides a detailed introduction to GPRS, HSCSD, and EDGE for packet-switched services and higher data ratesFeatures updated coverage on the vastly expanded range of GSM services, including an examination of Multimedia Messaging Service (MMS)Adopts a highly graphical approach with numerous illustrations

Das Mobilfunksystem GSM (Global System for Mobile Communication) ist mit einem Anteil von 60 % am Weltmarkt das wichtigste globale Mobilfunksystem. Das Buch stellt auf der Grundlage der europäischen GSM-Standards die technischen Grundlagen und die Systemarchitektur vor, insbesondere die Protokolle, die Mobilvermittlungstechnik und die Dienstrealisierung. Die erweiterte und aktualisierte Neuauflage enthält zusätzlich vor allem eine ausführliche Beschreibung des General Packet Radio Service (GPRS) und einen aktuellen Überblick zum Stand der Entwicklung der dritten Mobilfunkgeneration MTS/IMT-2000.

This book constitutes the refereed proceedings of the 5th InternationalWorkshop on Self-Organizing Systems, IWSOS 2011, held in Karlsruhe,Germany, in February 2011.The 9 revised full papers presented together with 1 invited paper werecarefully selected from 25 initial submissions. It was the 5th workshopin a series of multidisciplinary events dedicated to self-organizationin networked systems with main focus on communication and computernetworks. The papers address theoretical aspects of self-organization aswell as applications in communication and computer networks and robotnetworks.
