Low cost business terminals with small antennas (generally less than 2 metres in diameter) are often termed Very Small Aperture Terminals (VSATs). These are usually perceived as being two way data terminals, though strictly speaking many of the systems used for data broadcast are really one-way VSATs. Taking the USA as an example, approximately half of all installed VSATs are only used for one way data links.
