It contains contributions from leading research groups in academia and industry on …
Written from an operator’s viewpoint, HSPA Performance and Evolution explores the lessons learned and techniques developed for optimally deploying HSPA (High Speed Packet Access). The essential distinctions between rolling out HSPA compared to earlier UMTS and GSM technologies are explained covering the many issues that must be specifically handled. Areas in standards which have been left open for…
Find out how IAX can complement SIP to overcome complications encountered in current SIP-based communications Written by an expert in the field of telecommunications, this book describes the Inter-Asterisk Exchange protocol (IAX) and its operations, discussing the main characteristics of the protocol including NAT traversal, security, IPv6 support, interworking between IPv4 and IPv6, interworking …
An all-encompassing coverage on UMTS Networks including an in-depth discussion of current work on UMTS evolution and 4G . UMTS Networks and Beyond offers a comprehensive introduction to the networking aspects of UMTS and the networks coming after UMTS. The book is unique in that it systematically compares how a particular problem, e.g. obtaining connectivity, is solved in UMTS and how the same pro…
Ground Based Wireless Positioning provides an in-depth treatment of non-GPS based wireless positioning techniques, with a balance between theory and engineering practice. The book presents the architecture, design and testing of a variety of wireless positioning systems based on the time-of-arrival, signal strength, and angle-of-arrival measurements. These techniques are essential for developing a…
“Within the set of many identifier-locator separation designs for the Internet, HIP has progressed further than anything else we have so far. It is time to see what HIP can do in larger scale in the real world. In order to make that happen, the world needs a HIP book, and now we have it.” – Jari Arkko, Internet Area Director, IETF One of the challenges facing the current Internet architecture is t…
Wireless technologies continue to evolve to address the insatiable demand for faster response times, larger bandwidth, and reliable transmission. Yet as the industry moves toward the development of post 3G systems, engineers have consumed all the affordable physical layer technologies discovered to date. This has necessitated more intelligent and optimized utilization of available wireless resourc…
Mobile satellite services are set to change with the imminent launch of satellite personal communication services (S-PCS), through the use of non-geostationary satellites. This new generation of satellites will be placed in low earth orbit or medium earth orbit, hence, introducing new satellite design concepts. One of the first texts to cover this rapidly evolving field, this text provides the rea…
Content and Content Management are core topics in the IT and broadcast industry. However these terms have not been clearly defined for those learning the field. The topic is complex and users from different industries have different backgrounds and a varied understanding of content issues. Multimedia Content Management helps to clarify the subject area, define problematic issues and establish a un…
QoS (Quality of Service) and Network Management are old topics. However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in… It begins by examining the mecha…
With the current changes driven by the expansion of the World Wide Web, this book uses a different approach from other books on the market: it applies ontologies to electronically available information to improve the quality of knowledge management in large and distributed organizations. Ontologies are formal theories supporting knowledge sharing and reuse. They can be used to explicitly represent…
Ultra-wideband (UWB) has been among the most controversial technologies of modern times. Its applications seem endless, its capabilities miraculous and yet it is so poorly understood. In this volume, the authors combine talents to de-mystify ultra-wideband radio and explain it in language that is accessible to non-technologists as well as technologists. They contrast UWB with conventional radio te…
Revised and enlarged version that discusses how to design a mobile communications system. Comprehensively examines the mobile radio environment. Covers prediction of propagation loss, calculation and methods of reducing fades, interference, frequency plans and associated schemes, design parameters, signaling and channel access, cellular CDMA, microcell systems, and miscellaneous related systems. C…
