US Patent 10217346 Presence detection with neural networks

In a disclosed method, a computing device receiver, from a wireless receiver (RX), first data indicative of channel properties of a first communication link between the wireless receiver (RX) in a first device and a wireless transmitter (TX) in a second device. The first device and the second device are located in a building. The computing device further executes a neural network to process the first data to distinguish humans from stationary objects within the building and detect presence of the human in the building. The computing device transmits result data indicative of the presence to at least one of the first device or the second device.
