Abstract:
A mobile device capable of communication with wireless access points over wireless local area network (WLAN) channels, including prevailing channels corresponding to a region and non-prevailing channels corresponding to the region, includes: a scanning module configured to passively scan each channel of a subset of channels for a beacon signal; and a control module communicatively coupled to the scanning module and configured to control which channels the scanning module passively scans such that the subset of channels comprises multiple channels of the WLAN channels but less than all of the WLAN channels, and such that the subset of channels includes at least one of the prevailing channels.
Abstract:
Methods, apparatus, and techniques for provisioning geofences are disclosed. In one aspect, a map comprising one or more selectable geographic entities is displayed. In response to a selection by a user of at least one geographic entity of the one or more geographic entities, a geofence corresponding to the selected at least one geographic entity is created. In another aspect, a user may provide an input including one or more keywords. In response to determining that a first geographic entity has attributes that match the one or more keywords, a geofence corresponding to the first geographic entity is created.
Abstract:
Disclosed are systems, apparatus, devices, method, computer program products, and other implementations, including a method that includes capturing an image of a scene by an image capturing unit of a device that includes at least one sensor, determining relative device orientation of the device based, at least in part, on determined location of at least one vanishing point in the captured image of the scene, and performing one or more calibration operations for the at least one sensor based, at least in part, on the determined relative device orientation.
Abstract:
The disclosure is directed to determining whether or not a mobile device is indoors. The mobile device obtains a position fix based, at least in part, on an outdoor positioning system, and obtains one or more shape-files for one or more objects that are in proximity of the position fix.
Abstract:
Disclosed are systems, apparatus, devices, methods, computer program products, computer media, and other implementations, including a method that includes communicating data representative of one or more location-based restrictions corresponding to a venue area to a mobile device determined to be located within the venue area, and controlling, by at least one venue server, use at the mobile device of services available at the venue area from one or more nodes associated with the venue area based, at least in part, on a determination, by the at least one venue server, of whether the mobile device complies with the location-based restrictions corresponding to the venue area.
Abstract:
Various arrangements for performing location disambiguation are presented. A mobile device may receive a plurality of location hypotheses. The mobile device may also receive an indication of a disambiguation evaluation technique selected from a plurality of disambiguation evaluation techniques. The mobile device may perform the disambiguation evaluation technique using the plurality of location hypotheses. Using the disambiguation evaluation technique, a location hypothesis of the plurality of location hypotheses may be selected by the mobile device as corresponding to the mobile device's location.
Abstract:
Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized to facilitate or otherwise support one or more processes or operations in connection with binning venues into categories based, at least in part, on signal propagation characteristics associated with such venues.
Abstract:
The subject matter disclosed herein relates to systems, methods, apparatuses, articles, etc. for mobile device locating in conjunction with localized environments. For certain example implementations, a method may comprise obtaining at a mobile device one or more signals comprising information indicative of a location thereof. The information may be transmitted to one or more servers. A location context identifier (LCI) may be received responsive to the transmitting, with the LCI corresponding to a localized environment at which the mobile device is located. The LCI may be transmitted to the one or more servers. Location-based data may be received responsive to the transmitting of the LCI, with the location-based data being associated with the LCI and pertaining to the localized environment. The location of the mobile device may be determined with respect to the localized environment based, at least in part, on the location-based data. Other example implementations are described herein.
Abstract:
A method of disambiguating a location of a mobile station within a structure includes: obtaining, at the mobile station, regional pressure indications and corresponding region indications indicating regions within a structure that are vertically displaced with respect to each other, each of the regional pressure indications indicating atmospheric pressure information associated with the corresponding region; determining mobile station pressure information associated with a present location of the mobile station; comparing the mobile station pressure information with the regional pressure indications; and based on the comparing, determining in which of the regions the mobile station presently resides.
Abstract:
Various methods, apparatuses and articles of manufacture are provided which may be implemented in various devices for use in characterizing a signaling environment in an area of location uncertainty within an indoor structure. In an example, a computing device may obtain at least a portion of a travel log indicative measurements gathered by a mobile device within an area of location uncertainty, and a position fix based, at least in part, on one or more signals received at the mobile device within an area of location certainty. The computing device may, for example, determine an estimated trajectory of the mobile device within at least a portion of the area of location uncertainty within an indoor structure, e.g., leading to the position fix, based, at least in part on at least a portion of the plurality of measurements and the position fix.
