Illustratively, if the current transmit power of the current transmit link is 28dBm, the standard coupling power corresponding to the current transmit power can be found to be-2 dBm according to the preset power mapping table, that is, if the current transmit power is 28dBm, if the current transmit link is normal, the coupling power detected by the directional coupler should be-2 dBm.
And step 304, when the current coupling power corresponding to the current transmitting link is the noise floor power or the absolute value of the difference between the standard coupling power and the current coupling power is greater than a second set threshold, determining that the current transmitting link fails. The second set threshold is a value greater than 20 dBm.
And if the current coupling power of the current transmission link detected by the directional coupler is the noise-floor power, determining that the current transmission link fails.
