1. A processor-implemented method comprising:
- obtaining a speed of a Mobile Station (MS) in a plurality of mobile stations in communication with an Access Point (AP) in a wireless network; and
initiating an increase in a frequency of Round Trip Time (RTT) measurements between the MS and the AP during periods when the speed of the MS does not exceed a threshold.

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.
