Very Small Aperture Terminals (VSATs) / Edition 1

by John Everett

Overview

One of the most significant developments in telecommunications in the last decade, the very small aperture terminal (VSAT), as part of a satellite communications network, is the culmination of technology that allows earth terminals to be located on users' premises to provide data, voice and even video services. Networks based on VSATs can be established rapidly and reconfigured to respond to changing communications needs in a flexible and cost-effective manner.

In 28 chapters written by individuals who have made major contributions to the VSAT scene, Very Small Aperture Terminals describes the key technology underlying these systems, representative systems from leading vendors, link budgets, system protocols, data distribution based on television broadcasting, service provision, economic and, perhaps most importantly, regulatory issues.

Very Small Aperture Terminals is essential reading for anyone involved in telecommunications systems management or the engineering aspects, from equipment manufacturers to those who will use the systems. The technology and systems chapters will be of interest to practising engineers and postgraduate engineering students who require an introduction to the subject. Those with responsibilities for licensing and regulation will find their functions put into context.

Editorial Reviews

As part of a satellite communications network, VSATs allow earth terminals to be located on users' premises to provide data or voice and video services; they can be established rapidly and reconfigured to respond to changing communications needs flexibly and cost effectively. Twenty-eight contributions describe the key technology underlying these systems, representative systems from various vendors, budgets, protocols, service provision, economic, and regulatory issues. For those involved in telecommunications systems management or the engineering aspects. Annotation c. Book News, Inc., Portland, OR (booknews.com)
