First Claim
1. A method of collecting RF fingerprint data in a cross-correlated manner comprising:
- at each of a plurality of locations;
a. sensing RF signals with a wireless communication device to form first sensed data, the RF signals transmitted according to a first standard and the first sensed data for forming an RF fingerprint for identification of a location indoors;
b. sensing RF signals with a wireless communication device to form second sensed data, the RF signals transmitted according to a second other standard and the second sensed data for forming an RF fingerprint for identification of a location indoors;
c. sensing location to provide location data relating to said location; and
d. storing the first sensed data, the second sensed data and the location data within a database for forming a plurality of combined RF fingerprints each comprising first sensed data and second sensed data and location data related to each of a plurality of locations, the combined RF fingerprint data for providing more accurate localization indoors than either the first sensed data or the second sensed data in isolation.

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.
