When a detuning wave of several hundred kHz is input at a high level, sometimes the carrier sense (CCA) may not operate properly, causing the signal to be transmitted.
It is an unavoidable event in terms of the circuit mechanism. If there is an interference wave at a distance from the BPF band, RSSI is not detected since it hardly passes through the channel filter band. However, the interference wave signal is input to the circuits (LNA, MIX, etc.) at the stage preceding BPF. Therefore, if the signal is strong the pre-stage circuit becomes saturated, causing gain compression. Such events may occur if the correct RSSI value is not obtained.
