Abstract
In a general aspect, motion is detected based on statistical parameters of received wireless signals. In some aspects, signals are obtained. The signals are based on wireless signals transmitted through a space and received at a wireless communication device. Values of a set of statistical parameters are computed for each signal, and filtered values are obtained by applying a filter to the values of the statistical parameters. The filter includes parameters based on a signal quality analysis of the wireless signals. A motion detection process is executed to determine, based on the filtered values, whether an object moved in the space.
