About Powerline Communications
Product Description The intention of this work is to demonstrate the possibilities and limitations of PLC (Power Line Communications) technology with respect to individual needs. It presents and analyzes the background information and research results. From the Back Cover Power line-based communications networks: research, standards, applications, economics, and more. The state-of-the-art in power line communications: high-speed Internet access and beyond Maximizing data rates and minimizing electromagnetic compatibility problems Up-to-the-minute coverage of economic and regulatory issues For system evaluators, planners, designers, and technical implementers Power line communications (PLC) represents an exceptionally promising alternative for high-speed Internet access and data networking. Until now, however, little credible information has been available concerning R&D in the field. In Power Line Communications, leading researcher Klaus Dostert reviews significant technical progress toward high-speed information access over power lines at data rates of multiple Mbps. He explains how PLC can be integrated into existing telecommunications networks and reviews the economic and regulatory issues associated with deployment - including new opportunities in an era of utility deregulation. Coverage includes: PLC in context: historical roots, limitations, and potential Existing power networks and their characteristics PLC networking based on Europe's CENELEC EN 50065 standard Applications beyond Internet access: from home/building automation to digital audio and video from the wall-socket Technical options for maximizing data rates Solving electromagnetic compatibility problems Promising transmission and access methods The state-of-the-art in device and system development A realistic assessment of the future of power line communications An extensive bibliography, structured by issue Whatever your role in evaluating, designing, or implementing PLC networks, Power Line Communications offers the first single source for authoritative information on the state of the art. About the Author KLAUS DOSTERT has, since 1992, been full professor on the faculty of electrical engineering and information technology at the University of Karlsrühe in Germany, where he leads a PLC research group of eight scientists. His work has led to more than 50 scientific publications and 10 patents in the field of PLC. Dostert was keynote speaker at the International Symposium on Power Line Communications and its Applications and has initiated and chaired numerous PLC seminars and workshops. He holds a doctoral degree from the University of Kaiserslautern and is a senior member of the Computer Society of the IEEE. Excerpt. © Reprinted by permission. All rights reserved. Foreword The term "powerline" has splashed across the media more or less spectacularly for quite some time. Many of these representations are not sound enough to convey a realistic view of this technology and its possibilities to the public. Even experts are not fully familiar with the subject, because powerline is a unique medium for message transmission. This may help explain why powerline research and development has had a shadowy existence until recently. The only worthwhile applications had been seen in niches like building automation or remote meter reading. Extremely restrictive regulations with regard to the usable frequency ranges and admissible transmission levels have also discouraged powerline developments. There has not been massive economic interest to drive the formation of a powerline lobby like those in other technological fields, which would be able to exert influence on standards and regulations. This situation changed radically with the deregulation of the telecommunications and energy markets. One immediate consequence is the demand for alternative fast data connections on the local loop level. There is still a de-facto monopoly on this level, because all
