A device for RF sensing includes communication circuitry configured to communicate over an unlicensed frequency band and a licensed frequency band, the communication circuitry configured to transmit a unique signal over the unlicensed frequency band using at least one antenna of the one or more antennas and receive a corresponding return signal from at least one antenna of the one or more antennas, the at least one receiver configured to process the corresponding return signal to determine at least an amplitude and phase (td) of the corresponding return signal, and a look up table (LUT) having characterization information relating to the amplitude and phase (td) of the corresponding return signal, wherein the device is configured to use the characterization information to determine a use state or a gesture of the device and alter at least one operating parameter of the device based on the determined use state or gesture.
