Abstract
Techniques for improved wireless ranging are provided. A first communication from a first device is received at a first access point. A predefined minimum distance is determined for the first access point, where the predefined minimum distance corresponds to a distance at which the vertical location of the first access point causes inaccurate location estimations. A first distance of the first device from the first access point is estimated. Upon determining that the first distance of the first device is below the predefined minimum distance, fine timing measurement (FTM) requests from the first device are declined.
Claims20
A method, comprising:
- receiving, at a first access point, a first communication from a first device;
- determining a predefined minimum distance for the first access point, wherein the predefined minimum distance corresponds to a distance at which a vertical location of the first access point causes fine timing measurement (FTM) techniques to result in inaccurate location estimations;
- estimating a first distance of the first device from the first access point;
- upon determining that the first distance of the first device is below the predefined minimum distance, declining FTM requests from the first device.
A non-transitory computer-readable storage medium containing computer program code that, when executed by operation of one or more computer processors, performs an operation comprising:
- receiving, at a first access point, a first communication from a first device;
- determining a predefined minimum distance for the first access point, wherein the predefined minimum distance corresponds to a distance at which a vertical location of the first access point causes fine timing measurement (FTM) techniques to result in inaccurate location estimations;
- estimating a first distance of the first device from the first access point;
- upon determining that the first distance of the first device is below the predefined minimum distance, declining FTM requests from the first device.
A system comprising:
- one or more computer processors;
- and
- a memory containing a program which when executed by the one or more computer processors performs an operation, the operation comprising:
- receiving, at a first access point, a first communication from a first device;
- determining a predefined minimum distance for the first access point, wherein the predefined minimum distance corresponds to a distance at which a vertical location of the first access point causes fine timing measurement (FTM) techniques to result in inaccurate location estimations;
- estimating a first distance of the first device from the first access point;
- upon determining that the first distance of the first device is below the predefined minimum distance, declining FTM requests from the first device.
