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.

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.
