Samsung patents method to filter Wi-Fi distance errors for better location
This filing describes a way for a device to calculate its distance from another by taking multiple Wi-Fi timing measurements. If the results vary too much, the device groups them into clusters and uses the largest group to estimate the final distance, ignoring the outliers.
In the filing’s own words
A method for selecting measurements for positioning is disclosed. The method may include calculating, by an initiator device, a plurality of distance measurements, determining, by the initiator device, that a difference between a first value and a second value of the plurality of distance measurements is greater than a threshold, in response to the difference being greater than the threshold, dividing, by the initiator device, the plurality of distance measurements into N clusters, selecting, by the initiator device, a first cluster from among the N clusters based on a number of distance measurements in the first cluster, and outputting, by the initiator device, a distance between the initiator device and a responder device based on the distance measurements in the first cluster.
What exactly they claim (claim 1)
1. A method comprising: calculating, by an initiator device, a plurality of distance measurements; determining, by the initiator device, that a difference between a first value and a second value of the plurality of distance measurements is greater than a threshold; in response to the difference being greater than the threshold, dividing, by the initiator device, the plurality of distance measurements into N clusters; selecting, by the initiator device, a first cluster from among the N clusters based on a number of distance measurements in the first cluster; and outputting, by the initiator device, a distance between the initiator device and a responder device based on the distance measurements in the first cluster.
