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 (Block 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, VoiP or Video.
