A Practical Introductory Guide on Using Satellite Technology for Communications Executive Summary Satellites can provide global, ubiquitous and multipoint communica- tions. Not surprisingly, satellite technology has become a flexible and cost-effective solution for domestic and international networks, irrespective of the user’s geographic location. Wireline and wireless lack this ability to leap across continents and oceans, often linking some of the world’s most remote spots. Satellite technology can thus become a solution for some of the most complicated access problems, connecting cities across a large landmass, where copper or fiber would be cost prohibitive. Bringing broadband to the “last mile” of residences and businesses. Overcoming regulatory issues that make alternative carriers dependent on incumbents. Satellites also have a major role to play in designing, developing and expanding a network. With a satellite and Earth Stations, you can create a network on a permanent or interim basis much more rapidly than “laying cable.” An interim station will even let you test a market or provide emergency service prior to a major infrastructure investment. You can also rapidly scale and re-provision a satellite- based network to meet increasing and changing needs. The benefits of satellite communications have steadily expanded its usage. Today, satellites’ diverse purposes encompass wide area net- work communication, cellular backhaul, Internet trunking, television broadcasting and rural telephony. Satellites are also on the frontiers of such advanced applications as telemedicine, distance learning, Voice over Internet Protocol (VoIP) and video on demand (VOD). Intelsat has created this Primer to provide an introduction to the technology used in satellite networks. Our intention is help you understand, in general terms, why and how satellite technology might meet your needs. For more information, we invite you to talk to our experts a
