Selecting wireless communication channels based on signal quality metrics
First Claim
1. A motion detection method comprising:
- receiving, at a first wireless communication device, a first set of signals based on wireless signals transmitted through a space on a first wireless communication channel from a second wireless communication device;
by operation of one or more processors, computing a value of a signal quality metric based on the first set of signals;
selecting a second wireless communication channel based on a determination that the value of the signal quality metric does not meet a quality criterion for a motion detection process;
receiving, at the first wireless communication device, a second set of signals based on wireless signals transmitted through the space on the second wireless communication channel from the second wireless communication device; and
by operation of one or more processors, executing the motion detection process to detect motion of an object in the space based on the second set of signals.

Abstract
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 first wireless communication channel from a second wireless communication device. A signal quality metric value is computed based on the first set of signals, and a second wireless communication channel is selected based on a determination that the value of the signal quality metric does not meet a quality criterion for a motion detection process. The first wireless communication device receives a second set of signals based on wireless signals transmitted through the space on the second wireless communication channel from the second wireless communication device, and the motion detection process is executed to detect motion of an object in the space based on the second set of signals.
