Rain fade at Ku-band is not as sever as Ka-band. With the addition of current modem technology providing ACM (Adaptive Coding Modulation) and AUPC (Automatic Uplink Power Control) rain-fade doesn’t pose an issues to the operation of correctly configured Ku-band systems.
Ku-band hardware is generally cheaper than C-band hardware as the antenna and feed-horn required to operate at the higher frequency are smaller in size reducing the material costs of the manufacturing process.
Basic hardware requirements to connect a standard terrestrial Ku-band VSAT to an existing STAR network are:
- 1.2m parabolic Ku-band antenna
- 3W Ku-band BUC
- Ku-band LNB (in range required)
- Transmit and receive cables
- A modem compatible with the network chosen (iDirect, Newtec, etc.)
This is the basis for a VSAT operating with a download of up-to 8Mbps and an upload of up-to 512kbps.
