Apparatus, system, and method of waking up a computing device based on wireless sensing

A computing device comprising:

• one or more radios;
• one or more antennas connected to the one or more radios;
• a memory;
• and
• a controller configured to:
• maintain in the memory user device information to identify one or more user devices of a user;
• when the computing device is at a low power mode of operation, determine that a detected user device of the one or more user devices is within a user detection range from the computing device based on a wireless signal from the user device;
• based on determination that the user device is within the user detection range from the computing device, trigger a wireless proximity sensing to detect whether the user is within a wakeup range from the computing device based on channel estimation measurements corresponding to a plurality of Physical layer Protocol Data Units (PPDUs) received by the computing device over a wireless communication channel, the wakeup range is shorter than the user detection range;
• and
• based on detection that the user is within the wakeup range from the computing device, trigger the computing device to wakeup from the low power mode.

A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause a computing device to:

• maintain user device information to identify one or more user devices of a user;
• when the computing device is at a low power mode of operation, determine that a detected user device of the one or more user devices is within a user detection range from the computing device based on a wireless signal from the user device;
• based on determination that the user device is within the user detection range from the computing device, trigger a wireless proximity sensing to detect whether the user is within a wakeup range from the computing device based on channel estimation measurements corresponding to a plurality of Physical layer Protocol Data Units (PPDUs) received by the computing device over a wireless communication channel, the wakeup range is shorter than the user detection range;
• and
• based on detection that the user is within the wakeup range from the computing device, trigger the computing device to wakeup from the low power mode.
