Abstract:
1. A method comprising: receiving a new bound space that comprises an observed wireless fingerprint at a mobile apparatus and a corresponding geographical location for a given bound space; determining whether to at least one of accept and decline the new bound space based upon the observed wireless fingerprint compared to previously measured wireless fingerprints and locations; analyzing an average signal distance between the geographical location and a plurality of nearest neighbors that comprise existing bound spaces stored in a database wherein, when accepting the new bound space to a fingerprint of a current bound space for the mobile apparatus, an increase in the average signal distance improves the accuracy of the existing bound spaces stored in the database; accepting the new bound space to the fingerprint of the current bound space for the mobile apparatus in an instance in which adding the new bind to the database increases the current average signal distance between the geographical location and the plurality of nearest neighbors that comprise existing bound spaces stored in the database; declining the new bound space from the fingerprint of the current bound space for the mobile apparatus in an instance in which adding the new bind to the database decreases the current average signal distance between the geographical location and the plurality of nearest neighbors that comprise existing bound spaces stored in the database; and failing to associate the new bind with the geographic location in response to declining the new bound space.
