Hardcover. Condizione: new. Hardcover. A comprehensive discussion of multiple access protocols for cellular systems and the consideration of the specific constraints and capabilities of second and third generation systems regarding the multiple access protocols. Beginning by introducing the cellular concept and discussing second and third generation cellular communication systems, including the evolution from these systems to IP-based systems, the authors then identify the requirements for and problems related to multiple access. In accordance with ETSI and 3GPP standards, a split is made into basic multiple access schemes such as CDMA, TDMA and FDMA and multiple access protocols. The pros and cons of CDMA and TDMA for third generation systems are discussed as well as medium access in GSM, GPRS and UMTS, essentially based on R-ALOHA protocols in all these systems. Data access delay and voice dropping performance is assessed and the different UTRA modes are considered. * Provides an accessible text for individuals with little prior knowledge of cellular communication systems or multiple access protocols * Provides an overview of existing material on cellular communications, multiple access protocols and a combination of the two * Presents extensive research carried out by the authors including extended packet reservation multiple access protocols for TDMA, CDMA and hybrid CDMA/TDMA air interfaces, protocol enhancements and modelling of the physical layer A valuable reference resource for researchers and engineers in the field of cellular communications and packet-based communications, as well as postgraduate and research students in this rapidly evolving field. This title discusses the cellular concept and second and third generation cellular communication systems, including the evolution from these systems to IP-based systems. It then identifies the requirements for and problems related to multiple access. Shipping may be from our UK warehouse or from our Australian or US warehouses, depending on stock availability.

Buch. Condizione: Neu. Neuware - In leicht verständlichem Stil erläutern die Autoren dieses Buches Anforderungen an Multiple-Access-Protokolle für den Mobilfunk. Zu Beginn werden zellulare Kommunikationssysteme der 2. und 3. Generation eingeführt. Ausführlich beschrieben werden dann MA-Protokolle für paketorientierte zellulare Systeme. Ein großer Teil der vorgestellten Resultate stammt aus eigenen Forschungsarbeiten der Autoren, u.a. zur Verbesserung der Protokolle und zur Modellierung der physikalischen OSI-Schicht.
