FILTERING OUT ACCESS POINT DATA BASED ON NON-CONFORMITY WITH OTHER ACCESS POINT DATA

摘要

Methods and systems are described for filtering out signal strength data associated with access points and a client device using heuristic and intra-access point analysis. The filtered data may be used to approximate the location of the client device. By filtering signal strength values through a heuristic and intra-access point analysis; the systems and methods described eliminate inaccurate or anomalistic values, which may negatively alter the estimated location of the client device. Accordingly, the systems and methods may produce more accurate client device location estimates by intelligently examining detected signal strength values.

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:
obtaining information comprising a set of signal strength values corresponding to wireless signals received from a client device by each of a plurality of network devices; based on correlation between different signal strength values, selecting a first subset of signal strength values from the set of signal strength values to estimate a distance between the client device and a subset of the plurality of network devices corresponding to one of the first subset of signal strength values; and estimating a location of the client device based on the first subset of signal strength values and location of each of the subset of the plurality of network devices.
