What is VSAT


VSAT stands for “Very Small Aperture Terminal”, which refers to the technology whereby data is sent and received via an antenna. The antenna size is typically a 1.2m diameter for Ku-Band, or 1.8m diameter for C-Band. The difference between the two is the Frequency band in which they operate.


C-Band systems operate on a lower frequency (3-6 Ghz) and are therefore less affected by rain fade, however due to the size of the hardware they are more costly.


Ku-Band systems operate on a higher Frequency (12-14 Ghz), and allow for smaller antennas, but depending on the power of the satellite can be affected by bad weather conditions.


A typical VSAT installation will consist of the following:


  • A satellite antenna capable of transmitting and receiving data.
  • A BUC (Broadband Up Converter) for transmitting.
  • An LNB (Low Noise Block) for receiving.
  • Coaxial Cable from the antenna to the indoor modem.
  • A satellite modem capable of receiving and transmitting data such as e-mails, internet or video.
