Abstract: Methods of and systems for measuring beacon stability of wireless access points are provided. A method of determining a measure of likelihood that a designated wireless device exhibits at least one pathological characteristic includes determining a set of reference points associated with a designated wireless device, and retrieving attributes of the reference points, attributes associated with other wireless devices related to the designated wireless device, and/or statistical information. The statistical information includes a temporal distribution of detection of signals of reference points, a spatial distribution of the reference points, and/or a cardinality of the set or a subset of the reference points. The method further includes determining a measure of likelihood that the designated wireless device exhibits at least one pathological characteristic based on attributes of the reference points, attributes associated with the reception of signals, and/or the statistical information.

Abstract: Systems for and methods of determining likelihood of reference point identity duplication in a positioning system are disclosed. A method of determining a measure of likelihood that a designated identifier is shared by wireless devices includes determining reference points associated with any wireless device having a designated identifier. The reference points are a geographic position at which signals from any of the wireless devices were detected and/or wireless devices from which signals were also detected within a selected period of time during which the signals from any of the wireless devices having the designated identifier were detected. The method also includes determining statistical information about a temporal distribution of detection of signals of reference points, a spatial distribution of the reference points, and/or a cardinality of the reference points and determining a measure of likelihood that the designated identifier is shared by wireless devices is based on the statistical information.

Abstract: In one embodiment, a system determines a designated wireless device lacks a fixed geographic location, and uses the determination that the designated wireless device lacks a fixed geographic location to improve location estimates. The system determines one or more neighboring wireless devices have relationships with the designated wireless device, wherein a relationship is established when wireless signals from a neighboring wireless device and the designated wireless device are detected by a same receiver. A measure of likelihood is calculated that the designated wireless device lacks a fixed geographic location based at least in part on a number of the relationships or a duration of the relationships. Based on the measure of likelihood, the designated wireless device is excluded from being used in the wireless positioning system as a beacon for estimating the location of a client device.

Abstract: Systems for and methods of determining likelihood of relocation of reference points in a positioning system are disclosed. A method of determining a measure of likelihood that an estimated geographic location of a designated wireless device is not its accurate present location includes determining a set of reference points associated with the device, which are a geographic position at which signals from the device were detected and/or other devices having a relationship with the designated device. The existence of the relationship is based on the devices being within signal reception range of a same position within a selected period of time. The method includes retrieving attributes of the reference points and/or of the relationships and determining a measure of likelihood that an estimated geographic location associated with the designated device is not its present location based on the attributes of the reference points of the set and/or of the relationships.
