摘要： Described herein are techniques to enable a mobile device to perform multi-source estimation of an altitude for a location. A baseline altitude may be determined at ground level for a location and used to calibrate a barometric pressure sensor on the mobile device. The calibrated barometric pressure sensor can then estimate changes in altitude relative to ground level based on detected pressure differentials, allowing a relative altitude to ground to be determined. Baseline calibration for the barometric sensor calibration can be performed to determine an ambient ground-level barometric pressure.

摘要： Among other things, we describe a method that includes, on an electronic device, determining that a current quality metric of signals received by a location system of the electronic device does not meet a threshold quality metric, and based on the determination, selecting a recommendation for changing a position of the device in a manner that would alter the current quality metric. This aspect can also include corresponding systems, apparatus, and computer program products stored on a storage device.

摘要： Techniques of range free proximity determination are described. A mobile device can determine an entry into or exit from a proximity fence upon determining that the mobile device is sufficiently close to a signal source. The proximity fence can be a virtual fence defined by the signal source and associated with a service. The mobile device can detect signals from multiple signal sources. The mobile device can determine that, among the signal sources, one or more signal sources are located closest to the mobile device based on a ranking of the signal sources using signal strength. The mobile device can determine a probability indicating a confident level of the ranking. The mobile device can determine that the mobile device entered or exited a proximity fence associated with a highest ranked signal source satisfying a confidence threshold.

摘要： A wireless electronic device may include wireless communications circuitry and processing circuitry. The wireless communications circuitry may receive radio-frequency signals from external communications circuitry in a number of frequency channels of a communications band. The processing circuitry may gather received signal quality data such as receive signal strength indicator (RSSI) values from the radio-frequency signals received in each of the frequency channels. The processing circuitry may accumulate respective probability distributions of gathered RSSI values for each frequency channel and may compare each of the probability distributions to generate RSSI offset values for each frequency channel. The processing circuitry may gather additional RSSI values in one or more frequency channels and may adjust the additional RSSI values based on the associated RSSI offset values. The processing circuitry may use the adjusted RSSI values to determine an accurate location of the wireless electronic device.

摘要： A proximity fence can be a location-agnostic fence defined by signal sources having no geographic location information. The proximity fence can correspond to a group of signal sources instead of a point location fixed to latitude and longitude coordinates. A signal source can be a radio frequency (RF) transmitter broadcasting a beacon signal. The beacon signal can include a payload that includes an identifier indicating a category to which the signal source belongs, and one or more labels indicating one or more subcategories to which the signal source belongs. The proximity fence defined by the group of signal sources can trigger different functions of application programs associated with the proximity fence on a mobile device, when the mobile device moves within the proximity fence and enters and exits different parts of the proximity fence corresponding to the different subcategories.

摘要： In an example method, a computer system receives a query from a mobile device, including an indication of a location of the mobile device, and an environmental measurement obtained by the mobile device at the location. A set of candidate points of interest in geographical proximity to the location is determined. For each of one or more candidate points of interest of the set, a location fingerprint of the candidate point of interest and contextual data regarding the candidate point of interest are obtained. A similarity between the environmental measurement and each location fingerprint is determined. A particular candidate point of interest is selected from among the set based on the similarity, and based on an assessment of the contextual data. A label of the selected point of interest is associated with the location and transmitted to the mobile device.

摘要： In some implementations, a beaconing protocol can be used to broadcast beacon information to mobile devices. The beaconing protocol can be used by a Bluetooth Low Energy (LE) (e.g., Bluetooth 4.0) beacon to transmit a package of information that identifies the beacon and indicates the calibrated transmission power (e.g., measured power) of the beacon. The package of information can be configured by beacon providers and/or beacon installers at the locations where the beacons are installed. When a mobile device receives the beacon package, the mobile device can use the beacon identification information and/or the measured power of the beacon to determine a location (e.g., precise location, geofence location) of the mobile device. In some implementations, the mobile device can transmit the beacon information to a server and the server can determine the location of the mobile device and send location and/or content information back to the mobile device.
