VSAT 101

VSAT (Very Small Aperture Terminal) is a satellite technology that enables real-time broadband communications in areas where traditional terrestrial infrastructure is either unavailable or unreliable. It provides remote users with voice, data and fax capabilities similar to communications available at the corporate office. Users can make telephone calls, access the Internet and leverage applications to successfully run operations even if they are operating in isolated or harsh environments. Satellite networks are comprised of satellites, hubs and remote site equipment.

Corporate connections allow data to be shared to and from the remote sites and corporate and regional offices. The connections enable interoffice dialing at the remote sites and secure data transfer. A hub, also known as a master earth station, is typically an antenna larger than 4.5 meters in diameter. Several hubs operated on the same site are referred to as a teleport. Teleports located strategically around the globe support business continuity and global, mobile operations.
Satellite type and global position are chosen based on user coverage requirements and technical demands. Satellite transponders receive signals, amplify them and retransmit them back to Earth. Different antenna types are deployed based on whether users’ operations are on land or at sea and require fixed or transportable configurations. Installations have both outdoor equipment (the antenna, or VSAT, and transmission gear) and indoor equipment (modem, Ethernet switch and router) that provides the interface for phones, fax machines and computer connections.
