Abstract
In a general aspect, motion is detected using wireless signals. In an example, in response to a first series of sampling instructions asserted at a first sampling rate in a wireless sensing system, a first series of requests is sent for a wireless communication device to transmit a first series of wireless signals. The first series of wireless signals is received and motion detection output data is obtained based on the first series of wireless signals. A rate at which sampling instructions are asserted is changed from the first sampling rate to a second, different sampling rate based on the motion detection output data. In response to a second series of sampling instructions asserted at the second sampling rate in the wireless sensing system, a second series of requests is sent for the wireless communication device to transmit a second series of wireless signals.
