Advances in Wireless Communications.pdf下载

In the last few years, Rutgers University's WINLAB has hosted periodic workshops on third generation wireless information networks. The first Workshop, held in 1990, was a pioneering effort in trying to define the needs and technical challenges stimulated by this idea of integrated wireless networking. Since that first one, the WINLAB Workshops have been a forum for discussion of the issues arising in this research area, reaching out to diverse fields and addressing scientific as well as business, regulatory and sociological factors, which are also very important aspects to the development of the “wireless age”. Another characterizing factor of these meetings has been the effort to mix industry and university, in a continuous effort to define research areas that can be of long-standing impact as well as of immediate interest for commercial application. The presence of authors from both companies and universities, and papers jointly authored by industrial and academic partners, testify to the success of this viewpoint. The sixth Workshop was held in New Brunswick, NJ, on March 20-21, 1997. Although, by now, the number of people talking about third generation networks has dramatically increased and other conferences have sessions on this topic, experts from all over the world still recognize the importance of this event as a fruitful exchange of ideas, both during the presentations and during breaks and social events, in which state-of-the-art technologies are discussed and new solutions are sought. The papers presented at the Workshop, which are collected in this book, cover a broad range of topics. Papers describing state-of-the-art solutions are collected along with basic theoretical studies in information and communications theory, to offer what we think is a far-reaching panorama of this exciting field. The 25 contributions have been grouped in 6 areas, which form as many chapters in this book: Characterizing and Serving Mobile Users, ATM and Broadband, Power and Energy Management, Capacity and Performance, Propogation and Traffic Modeling, and Locating Mobile Users. It is seen that the topics cut across all the protocol layers. In fact, as challenging as the more standard communication theory related problems are, it is the multifaceted and multilayer system problem of wireless and mobile communications that offer the most significant opportunities for breakthroughs.
