Europe's leading experts from industry and academia present the results of the research into advanced mobile technologies and services performed within the scope of the ACTS R& D program in two new book volumes. Invaluable for industry professionals and researchers, the state-of-the-art in European R& D into wireless technologies is detailed in these two works.

Explore the present and future trends of WLANs and WPANs with this new, forwarding looking resource. You discover the path that these infrastructures are following from a perspective of synergies with 3G systems, and how they will pave the way for future 4G systems. The book presents a thorough overview of 3G networks and standards, and discusses interworking and handover mechanisms between WLANs and UMTS. You learn what performance can be expected from WLANs and WPANs when they support the TCP/IP stack. Several critical issues are examined in depth, including IP routing and mobility, , PHY and MAC layers for the main WLAN specifications, the TCP-UDP/IP protocol stack, and performance of TCP/IP over IEEE 802.11b.

This book reveals the state-of-the-art in wireless ad-hoc networking. It addresses many complex and open problems for researchers in the field of ad hoc networks. It further discusses some of the key research topics that are expected to promote and accelerate the commercial application of these networks (e.g., MAC, routing, QoS, optimization issues, service discovery, traffic models, mobility, handovers, security). It also presents "killer applications".

Despite frustrating customers and loss of revenue for telecommunications providers, cellular network congestion has remained a problem for which few solutions have been found. Covering GSM, GPRS, UMTS and beyond 3G systems, this practical book breaks new ground by providing you with proven techniques for decreasing blocking and dropped call rate due to network congestion. Using real measurements, this book clearly shows you that the maximum traffic that can be accommodated in a wireless network is not a constant value and varies significantly.

Annotation Written by a leading authority, this timely new work offers today's wireless professionals a complete understanding of OFDM technology and applications in wireless communications systems, placing emphasis on wireless LANs (local area networks) and PANs (personal area networks).

GSM, GPRS and EDGE Performance - Second Edition provides a complete overview of the entire GSM system. GSM (Global System for Mobile Communications) is the digital transmission technique widely adopted in Europe and supported in North America. It features comprehensive descriptions of GSM’s main evolutionary milestones - GPRS, (General Packet Radio Services) is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users. AMR and EDGE (Enhanced Data GSM Environment), and such developments have now positioned GERAN (GSM/EDGE Radio Access Network) as a full 3G radio standard. The radio network performance and capabilities of GSM, GPRS, AMR and EDGE solutions are studied in-depth by using revealing simulations and field trials. Cellular operators must now roll out new 3G technologies capable of delivering wireless Internet based multimedia services in a competitive and cost-effective way and this volume, divided into three parts, helps to explain how: 1. Provides an introduction to the complete evolution of GSM towards a radio access network that efficiently supports UMTS services (GERAN). 2. Features a comprehensive study of system performance with simulations and field trials. Covers all the major features such as basic GSM, GPRS, EDGE and AMR and the full capability of the GERAN radio interface for 3G service support is envisaged. 3. Discusses different 3G radio technologies and the position of GERAN within such technologies. Featuring fully revised and updated chapters throughout, the second edition contains 90 pages of new material and features the following new sections, enabling this reference to remain as a leading text in the area: Expanded material on GPRS Includes IMS architecture (Rel’5) and GERAN (Rel’6) features Presents field trial results for AMR and narrowband Provides EGPRS deployment guidelines Features a new chapter on Service Performance An invaluable reference for Engineering Professionals, Research and Development Engineers, Business Development Managers, Technical Managers and Technical Specialists working for cellular operators

The first of a three-volume series on the latest research and developments in the field of mobile communications, this cutting-edge resource offers practical insight into the next generation of wireless systems, services, and applications. Culled from groundbreaking research associated with the Information Society Technologies (IST) program, this unique book helps professionals understand how the networks of tomorrow will evolve into a common, open platform, capable of delivering a range of voice, video, and data services in a combined and seamless manner. This forward-looking volume covers a wide-range of important topics, from the architectures of future wireless systems and the importance of short-range systems in the global communication society, to service platforms/technologies and application platforms. The DVD included contains further details on critical topics related to the research discussed in the book.
