Publication number: 20140256349Abstract: 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.Type: ApplicationFiled: March 10, 2014Publication date: September 11, 2014Applicant: SKYHOOK WIRELESS, INC.Inventors: Farshid ALIZADEH-SHABDIZ, Nicolas BRACHET, Gerald CAVANAUGH, Andrei DANCUS, Russel K. JONES, Christopher STEGER

Publication number: 20140248902Abstract: 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.Type: ApplicationFiled: January 9, 2014Publication date: September 4, 2014Applicant: SKYHOOK WIRELESS, INC.Inventors: Farshid ALIZADEH-SHABDIZ, Nicolas BRACHET, Gerald CAVANAUGH, Andrei DANCUS, Russel K.

Publication number: 20140045525Abstract: 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.Type: ApplicationFiled: October 11, 2013Publication date: February 13, 2014Applicant: SKYHOOK WIRELESS, INC.Inventors: Farshid ALIZADEH-SHABDIZ, Nicolas BRACHET, Gerald CAVANAUGH, Andrei DANCUS, Russel K.

Publication number: 20130252631Abstract: Method of and systems for assigning estimated positions and attributes to wireless access points in a positioning system are disclosed. A method of estimating a characteristic of a wireless beacon includes receiving a set of data points. Each data point contains information about characteristics of a wireless beacon. The method also includes dividing at least one dimension into a set of regions in which each region of the set has region boundaries that do not overlap with other regions. The method further includes associating each data point with one corresponding region based on at least one element of the information of the data point lying within the boundaries of the corresponding region and determining an aggregate characteristic for each region based on the information of the data points associated with the corresponding region. The method estimates a characteristic of the wireless beacon based on at least one aggregate characteristic.Type: ApplicationFiled: March 13, 2013Publication date: September 26, 2013Applicant: SKYHOOK WIRELESS, INC.Inventors: Farshid ALIZADEH-SHABDIZ, Nicolas BRACHET, Andrei DANCUS, Christopher STEGER
