VSAT (Very Small Aperture Terminal)
VSAT (very small aperture terminal) is a two-way satellite ground station. VSATs are most commonly used to transmit narrowband data (point of sale transactions such as credit card, polling or RFID data; or SCADA), or broadband data (for the provision of satellite Internet access to remote locations, VoIP or video).
BUC (Block Upconverter)
A block upconverter (BUC) is used in the transmission (uplink) of satellite signals. It converts a band of frequencies from a lower frequency to a higher frequency. BUCs are generally used in conjunction with low-noise block converters (LNB). The BUC, being an up-converting device, makes up the “transmit” side of the system.
LNB (Low-Noise Block)
The LNB is a combination of low-noise amplifier, frequency mixer, local oscillator and IF amplifier. It receives the microwave signal from the satellite collected by the dish, amplifies it, and downconverts the block of frequencies to a lower block of intermediate frequencies (IF).
