“this volume should be acquired by college and university undergraduate and graduate libraries supporting degree programs in computer science, telecommunications, and business.” (E-STREAMS, April 2005)

“If you enjoy reading about the very latest technological revolutions, pick up a copy of this book…we love the book.” (Start Your Own Business, Summer 2005)  

Although telecom companies are battling for survival, technology is moving forward. In research laboratories around the world, powerful new technologies are being developed that will shape tomorrow’s communications world. Telecosmos will look at the many different telecom concepts that will be adopted by both consumers and businesses in the years ahead..

This book covers the applications of broadband PLC systems in low-voltage supply networks, a promising candidate for the realization of cost effective solutions for “last mile” communications networks. There are many activities surrounding the development and application of PLC technology in the access area, particularly because of strong interest of new network providers after the deregulation of telecommunications market. Nowadays, there are no existing standards for broadband PLC networks, which use a frequency range up to 30 MHz.

Broadband Powerline Communications: Network Design covers the applications of broadband PLC systems in low-voltage supply networks, a promising candidate for the realization of cost effective solutions for “last mile” communications networks. There are many activities surrounding the development and application of PLC technology in the access area, particularly because of strong interest of new network providers after the deregulation of telecommunications market. Nowadays, there are no existing standards for broadband PLC networks, which use a frequency range up to 30 MHz.

This book includes relevant and timely information regarding broadband PLC systems and especially PLC access networks and contributions to the design aspects of broadband PLC access systems and their network components.

This book:

• Offers explanations on how broadband PLC networks are realized, what the important characteristics for the transmission on electrical power grids are, and which implementation solutions have been recently considered for the realization of broadband PLC systems.
• Considers various system realizations, disturbance scenarios and their impact the transmission in PLC networks, electro-magnetic compatibility, applied modulation schemes, coding, and error handling methods.
• Pays particular attention to the specifics of the PLC MAC layer and its protocols, as well as the modelling and performance evaluation of broadband PLC networks.

Code division multiple access (CDMA) communication is rapidly replacing time- and frequency-division methods as the cornerstone of wireless communication and mobile radio. Theory of Code Division Multiple Access Communication provides a lucid introduction and overview of CDMA concepts and methods for both the professional and the advanced student.

Emphasizing the role CDMA has played in the development of wireless communication and cellular mobile radio systems, the author leads you through the basic concepts of mobile radio systems and considers the different principles of multiple access–time division, frequency division, and code division. He then analyzes three major CDMA systems–direct sequence (DS) CDMA systems, frequency hopped (FH) CDMA systems, and pulse position hopped (PPH) CDMA systems. Other topics covered include:

• Spread spectrum (SS) technology
• Forward error control coding
• CDMA communication on fading channels
• Pseudorandom signals
• Information theory in relation to CDMA communication
• CDMA cellular networks

Complete with useful appendices providing analyses of the moments of CDMA system decision statistics, Theory of Code Division Multiple Access Communication is a ready reference for every engineer seeking an understanding of the history and concepts of this key communications technology.

This first-of-its-kind book, from expert authors actively contributing to the evolution of Bluetooth specifications, provides an overview and detailed descriptions of all the security functions and features of this standard? latest core release. After categorizing all the security issues involved in ad hoc networking, this hands-on volume shows you how to design a highly secure Bluetooth system and implement security enhancements. The book also helps you fully understand the main security risks involved with introducing Bluetooth-based communications in your organization.

This cutting-edge resource examines all known attacks on Bluetooth security mechanisms and their implementations, demonstrating how some of these known weaknesses can be avoided with appropriate defensive measures. The book presents concrete examples of how to design security solutions for some Bluetooth applications and products built on these applications. You find real-world case studies including technical algorithms, mechanisms and protocols, and security architectures. These architectures offer valuable guidelines for use in building Bluetooth and non-Bluetooth-specific security mechanisms.
