Spaceway

Abstract: By the end of this decade, Hughes' SPACEWAY network will provide the first interactive 'bandwidth on demand' communication services for a variety of applications. High quality digital voice, interactive video, global access to multimedia databases, and transborder workgroup computing will make SPACEWAY an essential component of the computer-based workplace of the 21st century. With relatively few satellites to construct, insure, and launch - plus extensive use of cost-effective, tightly focused spot beams on the world's most populated areas - the high capacity SPACEWAY system can pass its significant cost savings onto its customers. The SPACEWAY network is different from other proposed global networks in that its geostationary orbit location makes it a truly market driven system: each satellite will make available extensive telecom services to hundreds of millions of people within the continuous view of that satellite, providing immediate capacity within a specific region of the world.

Abstract: From the Publisher: Gain sharper insight into each of today's telecommunications transmission systems, and make more informed decisions when choosing a particular system application with this comprehensive reference. It saves you time from searching through mountains of technical articles and white papers by offering an in-depth study of all five forms of transmission systems currently in use: copper lines, optical fiber, radio relay, mobile radio, and satellite. Without confusing technical jargon or heavy mathematics, the book first brings you up to speed with an overview of telecommunications and of transmission carrier equipment in general. It then moves on to provide a chapter-by-chapter examination of each transmission system in detail, from principle characteristics and underlying technologies, to specific applications. Other clearly written chapters enable you to... ? Compare and contrast each transmission system, and choose the most cost-effective system based on transmission requirements, geographical conditions, implementation and operation costs, and other key criteria ? Trace the future development of existing transmission systems, and explore soon-to-be-realized satellite systems for global mobile personal communications and global data transmission, including Iridium, Globalstar, Odyssey, ICO, Teledesic, and Spaceway ? Assess what chances new and future applications will have in the telecommunications market The book also includes information on dozens of existing transmission standards, a valuable glossary of abbreviations and acronyms, and more than 150 up-to-date references for further study.

Abstract: Satellite network capacity, adaptability, and responsiveness are enhanced with onboard capabilities for packet switching, bandwidth allocation, and spot-beams which facilitate uplink and downlink spectral reuse. A recent over-the-air (OTA) test of the SPACEWAY/sup TM/ system, a Ka-band regenerative satellite mesh network supporting IP packet services, provides definitive demonstration of key capabilities in the areas of quality-of-service, routing for unicast and multicast (both best-effort and guaranteed service) traffic, dynamic bandwidth resource allocation, security, and configurable satellite uplink and downlink components. Leveraging SPACEWAY system technologies and operational capabilities serves as a pragmatic step toward the development of future multi-satellite networks with more advanced features including onboard packet routing, multi-mode radio transmission, and inter-satellite links, which are now being considered for transformational satellite networks.
