Sinopsis
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.

De la contraportada
By focusing on multiple access for mobile communication systems, with a specific interest in access arbitration through multiple access protocols at the MAC (Medium Access Control) layer, the authors explain how packet-voice and packet-data traffic can be supported efficiently in mobile communication systems. This is approached from a theoretical point of view and from the context of existing systems such as GPRS and UMTS. The evolution of mobile communications from 1G to 3.5G and possible 4G scenarios are discussed.
* Examines the suitable MAC strategies for the support of packet-data on shared and common channels
* Describes the physical and logical channels in GSM, HSCSD and GPRS and examines the GPRS air interface features, including EGPRS and Release 4/5 enhancements
* Documents the authors extensive research efforts on PRMA-based protocols for CDMA, hybrid CDMA/TDMA and TDMA air interfaces
* Analyses the various options for packet-data support in UMTS Release 1999 on common and dedicated channels and planned enhancements in Release 5
* Summarises the challenges faced when wanting to support IP-based real-time and multimedia traffic efficiently in mobile communication systems and reviews how further evolutions of GPRS and UMTS attempt to meet these challenges
* Presents interesting research results on the benefits of channel access control in the context of reservation protocols
If you're looking for a comprehensive discussion of multiple access protocols, taking into account the constraints and capabilities of cellular communication systems, then this is the book for you. Engineers, researchers, academics and advanced students will all find it an important and valuable reference.
