From the satellite below the equipment to list (satellite frequency rental costs are not taken into account)
Antenna (the main station 4 meters 5, each sub-station 3 meters)
High-frequency head (low-noise amplifier, receiving device), power amplifiers (the power to be determined according to the situation, the transmitting device).
Inverter, modem (modulation and demodulation of satellite signals), serial server (parsing commands sent by the computer to the modem), data gateway (data transmission control), media gateway (control of video-audio transmission), switches (hub and sub-packet transmission), webcam (capture of video-audio), TV (output of video-audio), and computers (control of the units).
Wherein the power supply of the HF head and amplifier can be used outdoor power supply or indoor equipment upstream power supply, if the indoor equipment upstream power supply, then you need to add a splitter and combiner in the upstream section of the modem.
The specific connections can be illustrated by a simple topology diagram, which can't be posted here, so I'll send you an e-mail if you need it.
The main station (head office) and sub-station (subsidiary) equipment are the same, if the use of domestic equipment is relatively less expensive, but the quality is not quite guaranteed, it is recommended to use imported equipment.
The above is the program adopted by my company, you can explore.
