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.
