Abstract:
A method and apparatus are provided to permit location discovery, including location discovery in indoor settings. The method may identify a wireless fingerprint present at a geographical location and determine whether the wireless fingerprint corresponds to a previously observed wireless fingerprint associated with the predefined geographical location. A new wireless fingerprint and a geographical location, or bind, may be received by the system and the system may evaluate whether or not the new bind is erroneous or not, or if the new bind is an improvement over existing binds in determining whether or not to accept the new bind.
