摘要:One of the FCC's leading satellite communications experts spells out how to create, operate, and maintain satellite-based cellular communication networks in this guide. Bruno Pattan clarifies all aspects of cellular communications that employ satellites in non-geostationary (NGSO) and geostationary (GSO) orbits, giving you a working knowledge of the mechanical aspects of orbits ... cellular structuring ... signal analysis ... propagation anomalies ... and hand-held transceivers. , Complete with new information on frequency management, this guide delivers the tools you need to determine the spectrum and regulatory requirements for providing global data and voice service; calculate orbital geometries; deal with different propagation media; design ground receivers that offer the best voice quality, lowest power consumption, and optimum antenna pattern coverage; minimize interference between signals; and assure quality performance in a hostile transmission environment. Pattan also gives you an eye-opening preview of future systems that will provide global communications near the end of this millennium.
