    摘要： A mobile device receives a server-assisted location for a wireless access point, either a WiFi access point or a Bluetooth access point, from a remote location server comprising a reference database. The received server-assisted location is refined using a physical map or image. The mobile device is operable to acquire the physical map or image for a map-assisted location for the wireless access point. The mobile device compares the two locations to generate a valid location for the wireless access point. In instances where the two locations are consistent, the mobile device utilizes one of the two locations as the valid location for the wireless access point. Otherwise, the mobile device refines the server-assisted location utilizing the map-assisted location. The resulting refined server-assisted location is utilized as the valid location for the wireless access point and is transmitted to the remote location server to refine the reference database.

    摘要翻译： 移动设备从包括参考数据库的远程位置服务器接收用于无线接入点（WiFi接入点或蓝牙接入点）的服务器辅助位置。 接收到的服务器辅助位置使用物理地图或图像进行细化。 移动设备可操作以获取用于无线接入点的地图辅助位置的物理地图或图像。 移动设备比较两个位置以产生无线接入点的有效位置。 在两个位置一致的情况下，移动设备利用两个位置之一作为无线接入点的有效位置。 否则，移动设备利用地图辅助位置来优化服务器辅助位置。 所得到的精细服务器辅助位置被用作无线接入点的有效位置，并被发送到远程位置服务器以优化参考数据库。

    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 measures power from different locations for an encountered wireless access point, a WiFi or Bluetooth access point, and communicates the power measurements to a remote location. The remote location server collects power measurements for the encountered wireless access point from a plurality of communication devices. The remote location server determines the location of the encountered wireless access point utilizing corresponding power measurements from a single communication device. The power measurements are performed at different locations and over a period of time. The power measurements are time stamped and transmitted to the remote location server. The single communication device is selected based on quality and/or availability of corresponding power measurements for the encountered wireless access point. The determined location of the encountered wireless access point is stored into a reference database so as to be shared among the plurality of communication devices.

    摘要： A RFID reader of a RFID enabled mobile device receives RFID information from a RFID tag attached to an object. In instances where the RFID enabled mobile device is GNSS enabled, a GNSS position of the RFID enabled mobile device is determined to associate, for example, by location stamping, with the received RFID information. The location-stamped RFID information is communicated to a remote location server, where location-based RFID information is received from a plurality of users. The RFID enabled mobile device may communicate at least a portion of the received RFID information to the remote location server. When GNSS is not enabled, the RFID enabled mobile device estimates its own location utilizing location information, if available, for the object in the received RFID information. Otherwise, the RFID enabled mobile device acquires location-based RFID information from the remote location server so as to determine its own location.
