A Very Small Aperture Terminal (VSAT) is a device – known as a small private earth station – that is used to transmit & receive data signal through a satellite.
The “very small” component of the VSAT acronym refers to the size of the VSAT dish antenna -typically about 4 feet (1.2 m) diameter- that is mounted on a roof, or placed on the ground.
This antenna, along with the attached low-noise converter (LNB-which receives satellite signals) and the transmitter (BUC-which transmits the radio waves signals) make up the VSAT outdoor unit (ODU), one of the two components of a VSAT earth station.
The satellite modem which makes the connection between the computer is named the indoor unit (IDU) and does all management of that small private low cost earth station.
What are the advantages of VSAT?
Internet connectivity is no longer a luxury in business. Email, inter-office comms, VOIP, online order processing and countless other tasks require you to be online to get the job done. Despite how critical the internet is for business, many companies still have no back-up connection in place.
Satellite Internet services, such as Digital Cast packages for business offer true independence from the telephone network – keeping you online even if the phones go down.
Whether you are looking to protect yourself from something as mundane as copper cable theft, or need to ensure connectivity in the face of true disaster, Satellite Internet offers a robust means to ensure business continuity .
