摘要： A mobile device may be operable to collect location data for a RF node and cache the collected location data in the mobile device. Resources that may be utilized for improving the uploading of the cached location data to a location server may be determined by the mobile device. The cached location data may be communicated, to the location server for updating a location database, by the mobile device utilizing the determined resources. The mobile device may determine and utilize an opportunistic transport based on a data usage and/or an access. The mobile device may store a subset of the location database locally for comparing with the cached location data for redundancy. The compared location data may be transmitted by the mobile device to the location server for updating the location database if the compared location data are not redundant data.

摘要： A mobile device may be operable to receive historical location trail information of a building. A location of the mobile device within the building may be determined by placing, moving or snapping a reference location of the mobile device onto a trail according to the received historical location trail information. The historical location trail information may be acquired from a location server. The historical location trail information stored in the location server may be generated using a plurality of location samples that are provided by one or more other mobile devices that have been within the building. The historical location trail information may also be acquired from an indoor map of the building that is used by the mobile device for navigation within the building. The determined location of the mobile device may then be utilized by the mobile device to navigate within the building for location-based services.

摘要： A location server may be operable to refine a location for a RF node based on a weight applied to one or more location samples that are received from one or more mobile devices. The received location samples may be weighted based on a manufacturer and/or a model information of each of the mobile devices, properties and/or conditions of a RF environment associated with each of the mobile devices, a GNSS dilution of precision, motion sensors used by each of the mobile devices and/or a geometrical population condition associated with each of the mobile devices within range of the RF node. A valid location for the RF node may be generated utilizing the weighted location samples. The location server may update location information for the RF node, which may be stored in a location database, utilizing the valid location for the RF node.

摘要： A mobile device may be operable to determine, based on a known location of the mobile device, a location for a RF communication device that communicates with the mobile device, whenever the mobile device is within proximate range of the RF communication device. The determined location for the RF communication device may be stored in a location database in a location server and/or a memory in the RF communication device. The stored location of the RF communication device may then be used to determine a location for other mobile devices that may communicate with the RF communication device and are within proximate range of the RF communication device. The RF communication device may comprise a radio-frequency identification (RFID) device and/or a near field communication (NFC) device. The determined location for the RF communication device may comprise the known location of the mobile device.

摘要： Methods and systems for stabilizing a GNSS clock by reducing interference are disclosed and may include stabilizing a frequency of a temperature compensated crystal oscillator (TCXO) on a chip in a GNSS device. A clock signal may be generated for the device by temporarily configuring circuitry adjacent to the TCXO at a constant power level. Temperature and electromagnetic interference of the TCXO may be stabilized by the constant power level of the adjacent circuitry, which may be on the chip or external to the chip. The frequency of the TCXO may be stabilized by temporarily disabling the adjacent circuitry. A GNSS clock signal may be stabilized by the configuring of the constant power level while a GNSS location may be calibrated. A GNSS location of a fixed wireless device, such as a wireless access point, may be calibrated utilizing the configured constant power level and shared with other wireless devices.

摘要： Whenever a mobile device in a building is within proximity of a RF communication device, the mobile device may be operable to receive location information transmitted, for example by broadcasting it, from a RF communication device. The transmitted location information comprises altitude information of the RF communication device. At least an altitude of the mobile device may be determined based on the received altitude information of the RF communication device. The RF communication device may be located in an elevator car and/or on a particular floor in the building. Whenever the RF communication device is located in the elevator car, the altitude information of the RF communication device may be received by the RF communication device from an elevator controller. In instances when the RF communication device also transmits its latitude/longitude (LAT/LON), the mobile device may be operable to determine a 3-dimentional (3D) location of the mobile device.
