VSAT (Very Small Aperture Terminal) is a satellite communications system. A VSAT end user needs a box that interfaces between the user’s computer and an outside antenna with transceiver.
The transceiver receives or sends a signal to a satellite transponder in the sky. The satellite sends and receives signals from an earth station computer that acts as a hub or the system.
Each end user is interconnected with the hub station via the satellite in a star topology. For one end user to communicate with another, each transmission has to first go to the hub station which re-transmits it via the satellite to the other end user’s VSAT.
WHY USE VSAT?
VSAT handles data, voice, and video signals.
If you live in a remote area, then you are aware that there are a limited number of options when it comes to telecommunications and Internet connectivity.
This is especially true for field operations which are required to function in remote areas such as at sea, in the field, and in distant locations such as on oil rigs and utility services.
In terms of options, satellite communications represent the answer for most people in remote areas and one of the forms of this type of communication is known as VSAT which stands for Very Small Aperture Terminals.
