It provides a unified picture of important protocols for multimedia transport and session control, and explains what’s being done to tackle tough challenges in QoS control, mobility management, and security in the wireless environment. With enhancements to the next generation of the Internet protocol expected to provide greater support for wireless IP networks, the next Internet revolution may be just around the corner. This book provides professionals with what they need to know about the techniques and architectures that will get us there.

Recently, the emergence of wireless and mobile networks has made possible the admission of electronic commerce to a new application and research subject: mobile commerce, defined as the exchange or buying and selling of commodities, services, or information on the Internet through the use of mobile handheld devices. In just a few years, mobile commerce has emerged from nowhere to become the hottest new trend in business transactions. However, the prosperity and popularity of mobile commerce will be brought to a higher level only if information is securely and safely exchanged among end systems (mobile users and content providers).

Advances in Security and Payment Methods for Mobile Commerce includes high-quality research papers and industrial and practice articles in the areas of mobile commerce security and payment from academics and industrialists. It covers research and development results of lasting significance in the theory, design, implementation, analysis, and application of mobile commerce security and payment.

This volume examines the convergence of biotechnology and communication systems and explores how this convergence directly influences our understanding of the nature of communication. Editor Sandra Braman brings together scholars to examine this convergence in three areas: genetic information and “facticity”; social issues and implications; and the economic and legal issues raised by the production and ownership of information. The work highlights the sophisticated processes taking place as biotechnology and information technology systems continue to evolve.

The chapters in this book approach the complex history of this topic and the issues it raises from a number of directions. It begins by examining the shared features and spaces of biotechnology and digital information technologies as meta-technologies–qualitatively distinct from both the tools first used in the premodern era and the industrial technologies that characterized modernity. Next, the book explores what is and is not useful in treating the types of information processed by the two meta-technologies through a shared conceptual lens and looks at issues raised by the ownership of genetic and digital information. The final chapters are concerned with relationships between information and power.

"…very comprehensive and covers the entire topic of Raman amplification as applied to communication systems. As befitting a book of this length, the treatment is exhaustive and provides a range of information, from historical perspective, to current implementations, to some forecasts of important technologies for the future. Raman Amplification in Fiber Optical Communication Systems is an excellent book to fully understand how this cutting-edge technology works…In brief, I highly recommend reading this book." – Bertrand Desthieux, Editor-in-Chief of Optical Fiber Technology.

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.

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
