Abstract
Use of multiple sensors to determine whether motion of an object is occurring in an area is described. In one aspect, an infrared (IR) sensor can be supplemented with a radar sensor to determine whether the determined motion of an object is not a false positive.
Claims20
A computer-implemented method comprising:
- receiving, by one or more computer processors, data packets transmitted within a wireless communications link between at least one base station and at least one wireless access point (AP),
- wherein the wireless communications link is implemented within a physical area;
- extracting channel state information (CSI) of the wireless communications link from the data packets;
- analyzing a deviation in at least one of expected amplitude or phase of signals of the wireless communications link based on the CSI;
- determining an indication of motion of objects in the physical area based on analyzing the deviation in the at least one of expected amplitude or phase;
- sending the indication of motion to a cloud server;
- and
- sending a notification of the indication of motion to a user device for viewing the indication of motion, from the cloud server, on the user device.

A base station, comprising:
- one or more processors;
- and
- a computer-readable non-transitory memory storing instructions, wherein the one or more processors are configured to execute the instructions such that the base station is configured to:
- receive data packets transmitted within a wireless communications link by at least one wireless access point (AP);
- extract channel state information (CSI) of the wireless communications link from the data packets;
- analyze a deviation in at least one of expected amplitude or phase of signals of the wireless communications link based on the CSI;
- determine an indication of motion of objects based on analyzing the deviation in the at least one of expected amplitude or phase;
- and
- send the indication of motion to a cloud server.
