1. A processor-implemented method comprising:
- determining a motion associated with a Mobile Station (MS) in communication with an Access Point (AP) in a wireless network;
maintaining a frequency of Round Trip Time (RTT) measurements between the MS and the AP when the MS is stationary; and
in response to a determination that the motion associated with the MS exceeds a threshold, initiating a decrease in the frequency of RTT measurements between the MS and the AP.

Abstract
Systems, apparatus and methods disclosed herein utilize motion detection to estimate variability of positioning related metrics. In some embodiments, a method may comprise obtaining the speeds of a plurality of mobile stations in a set of mobile stations connected to an AP in a wireless network. The frequency of Round Trip Time (RTT) measurements between a mobile station in the plurality of mobile stations and the AP is increased during periods when the speed of the mobile station does not exceed a threshold. An estimate of variability may be obtained for RTT measurements for the AP.
