Abstract
A method for determining a location of a mobile electronic device includes receiving from said device, at a first electronic device, a first RF signal comprising a wireless signal according to a first standard other than a GPS standard. First RF fingerprint data is provided based on the first RF signal. A second RF signal comprising a wireless signal according to a second standard other than a GPS standard is received from said device at a second electronic device. Second RF fingerprint data is provided based on the second RF signal. Device specific RF signal fingerprint data is determined in dependence upon each of the first and second RF fingerprint data. The location of the device is determined using the first RF signal, the device specific RF signal fingerprint data for the first standard, the second wireless signal, and the device specific RF signal fingerprint data for the second standard.
