Claim One:
1. A method for detecting motion with a device, comprising: determining, at the device, one or more parameters indicative of a change in fading experienced by a wireless signal received by the device, wherein the determining the one or more parameters include: determining a fading profile indicative of how the wireless signal received by the device experiences fading at the device, and determining a second fading profile indicative of how a second wireless signal received by the device experiences fading at the device, wherein the one or more parameters are indicative of one or more differences between the fading profile and the second fading profile; determining, based on the one or more parameters indicative of the change in fading, whether a first of the device and an object in an environment of the device is moving; and responsive to a determination that the first of the device and the object is not moving, determining, based on the one or more parameters indicative of the change in fading, whether a second of the device and the object is moving, wherein a change in fading when the device is moving is greater than a change in fading when the device is stationary and the object is moving.
