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.
