Patent attributes
A device, system, and method are presented for detecting motion. The system may include the device and a first transmitter and a second transmitter configured to transmit a first set of wireless signals and a second set of wireless signals, respectively. The device may have a receiver configured to receive the first and second set of wireless signals, and may further include a processing unit that determines a first value and a second value indicative of fading attenuations experienced by the first set of wireless signals and the second set of wireless signals, respectively. The processing unit may further determine whether the first and second values are each consistent with motion of an object in proximity to the device. The processing unit may cause the device to output an indication of presence of the object if both values are consistent with motion of the object in proximity to the device.
