The satellite terminal uses a modified version of the Wi-Max Protocol. The forward channel works on DVB S2, but the return one works on MF-TDMA. The terminal consists of 3 components: the transmit-receive antenna, an outdoor unit (TRIA) and the indoor unit (modem).
The modem is a model Surfbeam RM4100N-010 of ViaSat. It has the following interfaces:
- 300-800MHz Rx, 1800-2300MHz Tx (1 connector)
- 1 x Ethernet interface (1Gbps)
- USB interface (for future service upgrade)
- 110/220Vac - 30Vdc power supply (<50m IFL length with RG6)
- Black box with blue LED indicators
There is a GUI ( Graphical user interface ) for status information and for the installation and activation of the link.
Maximum power usage: 24W max (typically 21W ).
Weight 1.5 kg., sizes 35x26x8 cm with packaging.
Reliability - MTBF: 22 years.
