1. A wireless network method comprising:
- by operation of a modem of a first wireless network device, communicating wireless network traffic on a first subset of wireless communication channels in a wireless communication network;
by operation of the modem of the first wireless network device, receiving motion detection signals transmitted through a space by a second wireless network device, the motion detection signals received on a second subset of wireless communication channels, the motion detection signals transmitted by the second wireless network device each comprising control data and a motion probe, each motion probe comprising a reference signal or a beacon signal;
communicating the wireless network traffic and receiving the motion detection signals in parallel;
processing the motion detection signals to detect motion of an object in the space; and
by operation of the modem of the first wireless network device, detecting motion of the object in the space by comparing the motion probes from the respective motion detection signals.

Abstract
In a general aspect, a motion detection channel is operated in a wireless communication network. In some aspects, a first wireless network device communicates wireless network traffic on a first subset of wireless communication channels in a wireless communication network. The first wireless network device receives motion detection signals transmitted through a space by a second wireless network device. The motion detection signals are received on a second subset of wireless communication channels. The motion detection signals are processed to detect motion of an object in the space.
