Interactive physical placement of devices for optimal motion sensing using channel state information (CSI)

A non-transitory computer readable storage medium storing instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving, at a first time, first channel state information (CSI) data representing channel properties of a wireless channel used by a first wireless device and a second wireless device, wherein the first wireless device is located at a first location in an environment and the second wireless device is located at a second location in the environment;
• determining that (i) a size of the first CSI data is less than a first threshold or (ii) the first CSI data is not received in a first specified time interval;
• sending, to a user device, a first indication that the first location of the first wireless device is not valid;
• receiving, at a second time after the first time, second CSI data representing channel properties of the wireless channel, wherein the first wireless device is located at a third location at the second time;
• determining that (iii) a size of the second CSI data exceeds the first threshold or (iv) the second CSI data is received in a second specified time interval;
• determining that the second CSI data corresponds to first ground truth data and indicates that there is no motion in the environment;
• or
• determining that the second CSI data corresponds to second ground truth data and indicates that there is motion in the environment;
• and
• sending, to the user device, a second indication that the third location of the first wireless device is valid.

A computing system comprising:

• a memory device that stores instructions;
• and
• a processing device, operatively coupled to the memory device, executes the instructions to perform operations comprising:
• receiving, at a first time, first channel state information (CSI) data representing channel properties of a wireless channel used by a first wireless device and a second wireless device, wherein the first wireless device is located at a first location in an environment and the second wireless device is located at a second location in the environment;
• determining that (i) a size of the first CSI data is less than a first threshold or (ii) the first CSI data is not received in a first specified time interval;
• sending, to a user device, a first indication that the first location of the first wireless device is not valid;
• receiving, at a second time after the first time, second CSI data representing channel properties of the wireless channel, wherein the first wireless device is located at a third location at the second time;
• determining that iii) a size of the second CSI data exceeds the first threshold or iv) the second CSI data is received in a second specified time interval;
• determining that the second CSI data corresponds to first ground truth data and indicates that there is no motion in the environment;
• or
• determining that the second CSI data corresponds to second ground truth data and indicates that there is motion in the environment;
• and
• sending, to the user device, a second indication that the third location of the first wireless device is valid.
