A system and method for characterizing performance of a terminal radio. The method includes obtaining a plurality of SNR feedbacks by, for each input power level of varying input power levels of the terminal radio, estimating an SNR (signal-to-noise ratio) associated with a respective input power level for a burst sent from the terminal radio to a gateway, where each of the SNR feedbacks may include an estimated SNR and the respective input power level; and determining a RC (radio characterization) of the terminal radio based on where the SNR feedbacks start deteriorating without indicating a saturated response at the gateway, where bursts are transmitted at a selected frequency with a selected SYMCOD (symbol, modulation and error coding scheme).

Terminal radio characterization

A system includes a satellite communications gateway including a first receiver. The first receiver is programmed to receive a first signal including a time-division multiplexed (TDM) return and a time-division multiple access (TDMA) return overlapped in an allocated frequency range. The receiver is further programmed to recover the time-division multiplexed return from the first signal; and output the time-division multiplexed return.

Overlapped TDM/TDMA satellite return communications

A satellite communication system, a method and a system are provided. In one aspect of the invention, an outdoor unit power source is connected to a switch of a satellite modem of an indoor unit. When the satellite modem receives a first signal from a wireless device, a first switch control signal is sent to the switch to open a connection between the outdoor unit power source and an inter-facility link connected to an antenna of an outdoor unit, thereby preventing power from flowing through the inter-facility link. When the satellite modem receives a second signal from the wireless device, a second switch control signal is sent to the switch to close a connection between the outdoor unit power source and the inter-facility link, thereby causing the power to flow through the inter-facility link. Other wirelessly received signals may cause various control signals to be sent via the inter-facility link.
