Method and apparatus for device-based indoor positioning using wi-fi fine timing measurements

A device comprising:

• a transceiver;
• and
• a processor operably connected to the transceiver, the processor configured to:
• scan for registered fine-time measurement (FTM)-enabled Wi-Fi nodes to generate a list of the FTM-enabled Wi-Fi nodes;
• perform a ranging operation by (i) selecting nodes to range with from the list of the FTM-enabled Wi-Fi nodes and (ii) processing ranging responses from the selected nodes to generate distance measurements;
• and
• estimate a position of the device based on the distance measurements generated from the ranging operation.

A non-transitory computer readable medium comprising program code that, when executed by a processor of a device, causes the device to:

• scan for registered fine-time measurement (FTM)-enabled Wi-Fi nodes to generate a list of the FTM-enabled Wi-Fi nodes;
• perform a ranging operation by (i) selecting nodes to range with from the list of the FTM-enabled Wi-Fi nodes and (ii) processing ranging responses from the selected nodes to generate distance measurements;
• and
• estimate a position of the device based on the distance measurements generated from the ranging operation.
