1. A method comprising: providing a central fingerprint database operable to store a fingerprint for proximity detection, the fingerprint characterizing proximity of a femtocell; executing a fingerprint manager in communication with the fingerprint database for: creating the fingerprint, and storing, for the fingerprint, a fingerprint component that characterizes proximity of the femtocell; and executing a proximity detector in communication with the fingerprint database, and, with the proximity detector: obtaining an environmental measurement; analyzing the fingerprint to find that the fingerprint is a matching fingerprint with respect to the environmental measurement; and initiating a cell search for a specific femtocell that corresponds to the matching fingerprint.
