Receiver diversity for wi-fi sensing

A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

• identifying, by a first device, first packets received from a second device during a time period, the first packets received using a first communication link between the first device and the second device;
• identifying, by the first device, second packets received from a third device during the time period, the second packets received using a second communication link between the first device and the third device;
• determining, based on the first packets, a first value indicative of a first amount of channel state variance associated with the first communication link during the time period, wherein the first amount of channel state variance is indicative of first motion between the first device and the second device;
• determining, based on the second packets, a second value indicative of a second amount of channel state variance associated with the second communication link during the time period, wherein the second amount of channel state variance is indicative of second motion between the first device and the third device;
• and
• causing to send the first value and the second value.

A method for performing Wi-Fi sensing, the method comprising:

• identifying, by processing circuitry of a first device, first packets received from a second device during a time period, the first packets received using a first communication link between the first device and the second device;
• identifying, by the processing circuitry, second packets received from a third device during the time period, the second packets received using a second communication link between the first device and the third device;
• determining, by the processing circuitry, based on the first packets, a first value indicative of a first amount of channel state variance associated with the first communication link during the time period, wherein the first amount of channel state variance is indicative of first motion between the first device and the second device;
• determining, by the processing circuitry, based on the second packets, a second value indicative of a second amount of channel state variance associated with the second communication link during the time period, wherein the second amount of channel state variance is indicative of second motion between the first device and the third device;
• and
• causing to send, by the processing circuitry, the first value and the second value.
