An identification marking is incorporated into a light fixture to provide a uniquely identifiable light fixture. The identification marking is humanly imperceptible. Location information for the uniquely identifiable light fixture is obtained by a mobile device after identifying the light fixture based on the identification marking. Location of the mobile device is estimated based on the obtained location information of the uniquely identifiable light fixture.
