Satellite communication using VSATs are an ideal option for networking because they enable Enterprise Wide Networking with high reliability and a wide reach which extends even to remote sites. The Advantage of using satellite communications are as follows!

  1.Huge Geographical Coverage

You must be well aware of the limitations faced by terrestrial lines in reaching remote and other difficult locations. VSATs,on the other hand, offer you unrestricted and unlimited reach.

2.Extremely reliable Uptime of upto 99.5 percent is achievable on a VSAT network. This is significantly higher than the typical leased line uptime of approximately 80 to 85 percent. 3.Network Management Network monitoring and control of the entire VSAT network is much simpler than a network of leased lines, involving multiple carriers at multiple locations. A much smaller number of elements needs to be monitored incase of a VSAT network and also the number of vendors and carriers involved in between any two user terminals in a VSAT network is typically one. This results in a single point of contact for resolving all your VSAT networking issues. A VSAT NMS easily integrates end-to-end monitoring and configuration control for all network subsystems.

A brief history of space communication ! The idea of radio transmission through space was first conceived in 1911.In 1945, Arthur C. Clarke proposed the idea of using earth-orbiting satellite as a relay point for communication between two earth stations.This idea later led to the great success of satellite communications.In 1957, the Soviet Union launched Sputnik I , which transmitted telemetry signals for 21 days.In 1958, United States launched Explorer I, which transmitted telemetry signals for 5 months.

In July 1964, INTELSAT, a multinational organization, was formed with the purpose to design, develop, construct, establish, and maintain the operation of the space segment of a global commercial communications satellite system. In April 1965, Early Bird (INTELSAT I), a geostationary communications satellite was launched. In a span of seven years, four generations of satellites – INTELSAT I through IV were launched and placed in commercial operation. (more…)
