AbrégéMethods and devices for detecting wireless signal absorption using power sensing circuitry. One method includes receiving, by a receiving device having power sensing circuitry, a plurality of wireless signals from a plurality of transmitting devices. The power sensing circuitry may include a local oscillator, a mixer, and a band-pass filter. The method may also include detecting, by the power sensing circuitry, a plurality of power levels for the plurality of wireless signals, where each power level of the plurality of power levels corresponds one of the plurality of wireless signals. The method may further include analyzing, by one or more processors, the plurality of power levels to determine three characteristic power levels of the plurality of power levels. The method may further include calculating, by the one or more processors, an absorption amount based on the three characteristic power levels.
