Highly integrated very small aperture terminal (VSAT) apparatus and method
View Patent ↗A method, and a VSAT capable of being configured for such a method, of configuring a VSAT, the steps of which are setting, while an outdoor unit of the VSAT is at a configuration location, a maximum value of the adjustable gain of the up-converting device and transmitting, from an operating location that is separate from the configuration location, transmission signals to the satellite at the transmission frequency and with a gain value of at most the maximum value of the adjustable gain set at the configuration location.
1. A system for communicating with a satellite, the system comprising:
an indoor unit (IDU), including an orthogonal frequency-division multiplexer configured to combine a DC power signal and a data signal into a bi-direction transmission signal, and output the transmission signal along a coaxial cable; and
an outdoor unit (ODU) including electronic devices configured to receive the transmission signal via the coaxial cable, extract the data signal from the transmission signal, amplify the transmission signal, and transmit the extracted data signal to the satellite, wherein the electronic devices are energized using the DC power signal.
2. The system of claim 1 , wherein the electronic devices in the ODU includes a de-multiplexer configured to de-multiplex the transmission signal received via the coaxial cable to separate the extracted data signal from the DC power signal.
3. The system of claim 1 , wherein the DC power signal has a voltage of at most 59 V and a power transmission of at most 100 Watts.
4. The system of claim 1 , wherein the IDU is configured to condition the DC power signal along the coaxial cable for hot connect and hot disconnect, wherein hot is defined as a live DC power signal.
5. The system of claim 1 , wherein the IDU includes circuitry for short circuit protection.
