This book provides critical background material in wireless communications, traffic modeling and traffic engineering techniques. It gives high-level descriptions of CDMA2000/UMTS and WLAN systems, discusses some of the issues that engineers face when designing these systems, and provides innovative solutions for these issues. Also treated are new and upcoming features, e.g. IP multimedia subsystems, multimedia broadcast/multicast services and Push-to-Talk over Cellular (PoC) for 3G networks. The book is very useful for system designers who do not have prior experience designing practical 3G wireless systems. The level of presentation is suitable for graduate students and practical engineers with some prior undergraduate-level courses in digital communications and networking. Problems included at the end of each chapter provide review and reinforcement of key topics.

Dalla quarta di copertina:

Design and Performance of 3G Wireless Networks and Wireless LANs is for wireless communication system engineers, network engineers, professionals, and researchers. Network architectures of UMTS, CDMA2000 systems, and how major network elements within the 3G networks can be designed, are described. In addition, the authors describe how end-to-end performance for voice and data services can be determined. They also provide guidelines on how radio access networks and core networks can be engineered. Of equal importance, is inclusion of explanations of various wireless LAN standards (IEEE 802.11a, 802.11b, 802.11g, 802.11e) and how voice and data services can be offered in the wireless LAN systems.

Additional highlights include:

* Overview of core principles of wireless communications (e.g., FDMA, TDMA, CDMA), airlink capacity analysis, and evaluation.

* Traffic model descriptions and illustrations for circuit-switched and packet-switched services.

* In-depth coverage of how base station and radio network controller can be designed to meet capacity requirements.

* Discussion of unique design issues in 3G networks, innovative solutions, and possible new 3G features.

This material also provides capacity engineering guidelines for 3G networks and wireless LANs. Review exercises are provided at the end of each chapter to facilitate teaching and self study.
