Abstract
A method of collecting RF fingerprint data in a cross-correlated manner is disclosed. At each of a plurality of locations RF signals are sensed with a wireless communication device to form first sensed data, the RF signals transmitted according to a first standard. At each of the plurality of locations RF signals are sensed with a wireless communication device to form second sensed data, the RF signals transmitted according to a second other standard. Location is sensed to provide location data relating to said location. Then, the first sensed data, the second sensed data and the location data are stored within a database for forming a plurality of RF fingerprints related to a plurality of locations.
