8.7 RSSI

RSSI (Received Signal Strength Indicator) is an indicator of the received signal strength. The RSSI value is usually a relative quantity used to measure the strength of the received wireless signal power. In wireless communication systems, the size of the RSSI value is very important for evaluating communication quality, signal coverage, and determining whether to adjust transmit power or receive sensitivity.

When RTK uses radio to transmit or receive differential signals, the RSSI function can be used to assist in checking the signal strength of the current radio station.
