Method includes maintaining a collaborative database on a database server containing geographic location information pertaining to Wi-Fi access points. The collaborative database includes database records for Wi-Fi access points including a MAC address and geographic location. A position location request from a Wi-Fi enabled wireless device is received at a server, and includes a respective MAC address of at least one Wi-Fi access point for which a wireless beacon is detected by the wireless device. Via a query issued to the database server using at least one MAC address included in the position location request, geographic location data for one or more Wi-Fi access points is retrieved from the database. A processor determines geographic location of the wireless device based at least on the retrieved geographic location data, and returns, via the server, geographic location data to the wireless device corresponding to the geographic location of the wireless device. |

1. A method, comprising:
maintaining a collaborative database on a database server containing geographic location information pertaining to Wi-Fi access points, the collaborative database including database records for each of a plurality of Wi-Fi access points including a MAC address and geographic location of the Wi-Fi access point, wherein at least a portion of the database records are based on Wi-Fi identification and geographic location data received from a plurality of Wi-Fi- and GPS-enabled wireless devices such that the collaborative database is built in a collaborative manner; receiving, at a server, a position location request from a wireless device that is Wi-Fi enabled, the position location request including a respective MAC address of at least one Wi-Fi access point for which a wireless beacon is detected by the wireless device; retrieving, via a query issued to the database server using at least one MAC address included in the position location request, geographic location data for at least one of the Wi-Fi access points from the collaborative database; determining, via a processor, a geographic location of the wireless device based at least on the geographic location data retrieved from the collaborative database; and returning, via the server, geographic location data to the wireless device corresponding to the geographic location of the wireless device that is determined. |
