Patent attributes
In a general aspect, a wireless communication channel is selected based on signal quality metrics. In some aspects, a first wireless communication device receives a first set of signals based on wireless signals transmitted through a space on a set of wireless communication channels from a second wireless communication device. A signal quality metric value is computed for each wireless communication channel based on the first set of signals, and one of the wireless communication channels is selected based on a comparison of the signal quality metric values for the respective wireless communication channels. The first wireless communication device receives a second set of signals based on wireless signals transmitted through the space on the selected wireless communication channel from the second wireless communication device, and a motion detection process is executed to detect motion of an object in the space based on the second set of signals.
