This book was released on 2018-10-23 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study has investigated alternatives for realizing a packet-based network switch for deployment on a communication satellite. The emphasis was on the avoidance of contention problems that can occur due to the simultaneous arrival of an excessive number of packets destined for the same downlink dwell. The study was to look ahead, beyond the current Advanced Communications Technology Satellite (ACTS) capability, to the next generation of satellites. The study has not been limited by currently available technology, but has used university and commercial research efforts as a basis for designs that can be readily constructed and launched within the next five years. Tradeoffs in memory requirement, power requirement, and architecture have been considered as a part of our study. Stehle, Roy and Ogier, Richard G. Unspecified Center NAS3-25934; RTOP 506-72-21...

Book Synopsis An Overview and Comparison of Demand Assignment Multiple Access (DAMA) Concepts for Satellite Communications Networks by :
Download or read book An Overview and Comparison of Demand Assignment Multiple Access (DAMA) Concepts for Satellite Communications Networks written by and published by . This book was released on 1996 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a broad survey of demand assignment multiple access (DAMA) techniques for satellite communications. The primary intended audiences are military planners, communications system designers and architects, and the military acquisition community at large. However, much of the material in this report will also be of interest for commercial communications system planners and designers, especially where there is a potential for military use of these commercial systems. The report describes a wide (but not exhaustive) set of DAMA techniques, with emphasis on those techniques that offer the greatest practical benefit for military applications. Methods for making DAMA systems resistant to interference and jamming are discussed, including some new methods. The report covers both pure DAMA protocols, which efficiently handle voice traffic and long data transmissions, and hybrid DAMA protocols, which can efficiently handle not only voice and long data transmissions, but also short data transmissions (packets). Because of the increasing importance of packetized communications for the military, an entire chapter is devoted to the subject of hybrid DAMA. Selected performance results are presented, including some new performance results. To make the material in this report accessible to readers with only a basic background in communications, a substantial amount of tutorial material has been included.

Download or read book The Evolution of Untethered Communications written by National Research Council and published by National Academies Press. This book was released on 1998-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems. In addition to advising DARPA on where its investment in information technology for mobile wireless communications systems can have the greatest impact, the book explores the evolution of wireless technology, the often fruitful synergy between commercial and military research and development efforts, and the technical challenges still to be overcome in making the dream of "anytime, anywhere" communications a reality.
