Abstract
In a general aspect, motion is detected by processing wireless signals using stored modem parameters. In some aspects, stored modem parameters are accessed from a memory of a wireless sensor device. The stored modem parameters represent a radio state previously used by a radio subsystem of the wireless sensor device in processing a first motion detection signal. The stored modem parameters are applied to the radio subsystem of the wireless sensor device, a second motion detection signal is processed at the wireless sensor device using the radio state represented by the stored modem parameters, and motion is detected based on the first and second motion detection signals.
