Patent number: 9369884Abstract: In one embodiment, characteristics of signals received from Wi-Fi access points during a traversal of a number of drivable streets within a geographic area having a radius of one or more miles are determined, the characteristics of a given signal including a unique identifier of a Wi-Fi access point that transmitted the signal, a location where the signal was observed, and an observed signal strength at the location where the signal was observed. Using the characteristics, a reference database is built including records descriptive of Wi-Fi access points in the geographic area. To determine a current location of a mobile device, an observed signal strength of one or more Wi-Fi access points observed by the mobile device from the current location is determined and a current location of the mobile device is computed using at least the observed signal strength of the one or more Wi-Fi access points observed by the mobile device in comparison to information in the reference database.Type: GrantFiled: August 11, 2014Date of Patent: June 14, 2016Assignee: Skyhook Wireless, Inc.Inventors: Russel K.

Publication number: 20150241548Abstract: In one example embodiment, a Wi-Fi based location determination technique both determines one or more locations of a mobile device, and calculates a confidence score for each determined location. A request is received at a certified location service executing on a server for one or more locations of the mobile device and a data package. The data package may include an indication of a plurality of beacons observed by the mobile device. The certified location service determines one or more locations of the mobile device based on a calculated location of at least some of the plurality of beacons. The certified location service also determines a confidence score for each beacon used in determining each location. An overall confidence score for each determined location may be calculated based on a combination of the confidence scores for each of the beacons used in the determination of the location.Type: ApplicationFiled: February 24, 2015Publication date: August 27, 2015Inventors: Russel K.

Publication number: 20150181378Abstract: 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.Type: ApplicationFiled: March 2, 2015Publication date: June 25, 2015Inventors: Farshid Alizadeh-Shabdiz, Nicolas Brachet, Gerald Cavanaugh, Andrei Dancus, Russel K.

Publication number: 20150172863Abstract: In one embodiment, when it is determined that one or more Wi-Fi positioning system (WPS) tiles that are necessary to estimate a location of a mobile client device are not present in a WPS tile store on the mobile client device, or are present in the WPS tile store on the mobile client device but out of date, one or more new WPS tiles are requested from a remote server. Each WPS tile is a set of Wi-Fi access point data for Wi-Fi access points within a bounded geographical region. The one or more new WPS tiles are received from the remote server, and are cached in the WPS tile store on the mobile client device. Subsequent to the caching, one or more further locations of the mobile client device are estimated autonomously from the remote server, utilizing Wi-Fi access point data in the WPS tile store.Type: ApplicationFiled: February 20, 2015Publication date: June 18, 2015Inventors: Nicolas Brachet, Farshid Alizadeh-Shabdiz, Joel N.

Patent number: 9037162Abstract: Methods and systems of continuously optimizing data in WiFi positioning systems. A location-based services system uses WiFi-enabled devices to monitor WiFi access points in a target area to indicate whether a WiFi access point is newly-observed. A WiFi-enabled device communicates with WiFi access points within range of the WiFi-enabled device so that observed WiFi access points identify themselves. A reference database is accessed to obtain information specifying a recorded location for each observed WiFi access point in the target area. Observed WiFi access points for which the reference database has no information specifying a corresponding recorded location are identified. The recorded location information for each of the observed WiFi access points is used to calculate the position of the WiFi-enabled device. The reference database is informed of the WiFi access points (for which there was no information in the database) and is provided the calculated position in conjunction therewith.Type: GrantFiled: March 20, 2012Date of Patent: May 19, 2015Assignee: Skyhook Wireless, Inc.Inventors: Edward J. Morgan, Michael G. Shean, Farshid Alizadeh-Shabdiz, Russel K. Jones

Patent number: 8965412Abstract: In one embodiment, in response to a user application request to determine a location of a user-device having a Wi-Fi radio, the Wi-Fi radio is triggered to transmit a request to Wi-Fi access points within range. Messages are received from the Wi-Fi access points, each message identifying the Wi-Fi access point sending the message. Signal strength of the messages received from the Wi-Fi access points is calculated. A reference database of stored locations for Wi-Fi access points in a target area is accessed to obtain the stored locations for the identified Wi-Fi access points. Based on the number of the identified Wi-Fi access points identified via received messages, a corresponding location-determination algorithm is chosen from a plurality of location-determination algorithms. The location of the user-device is determined using the stored locations for the identified Wi-Fi access points, the signal strengths of the received messages and the chosen location-determination algorithm.Type: GrantFiled: March 8, 2013Date of Patent: February 24, 2015Assignee: Skyhook Wireless, Inc.Inventors: Farshid Alizadeh-Shabdiz, Russel K.

Patent number: 8837363Abstract: A location beacon database and server, method of building location beacon database, and location based service using same. Wi-Fi access points are located in a target geographical area to build a reference database of locations of Wi-Fi access points. At least one vehicle is deployed including at least one scanning device having a GPS device and a Wi-Fi radio device and including a Wi-Fi antenna system. The target area is traversed in a programmatic route to reduce arterial bias. The programmatic route includes substantially all drivable streets in the target geographical area and solves an Eulerian cycle problem of a graph represented by said drivable streets. While traversing the target area, Wi-Fi identity information and GPS location information is detected. The location information is used to reverse triangulate the position of the detected Wi-Fi access point; and the position of the detected access point is recorded in a reference database.Type: GrantFiled: September 6, 2011Date of Patent: September 16, 2014Assignee: Skyhook Wireless, Inc.Inventors: Russel K.
