Signal attenuation obstructing
http://journal.buitms.edu.pk/j/index.php/bj/article/view/7/8 Attenuation decreases the intensity of electromagnetic radiation due to absorption or scattering of photons. Attenuation does not include the decrease in intensity due to inverse-square law geometric spreading. Therefore, calculation of the total change in intensity involves both the inverse-square law and an estimation of attenuation over the path.

I attached my circuit diagram. Basically it just a simple voltage source (from MIC) + bandpass filter with positive rectifier (range within 5KHz bandwidth) and this signal will input to ADC for detection.

Likely there will be some adaptive control over transmit power, but there are limits. Beyond that, as there's bidirectional communication, you can negotiate a reduced bitrate (change modulation and/or coding) to get better resilience.
