1. A method comprising:
receiving, by one or more processors, at least one radio signal in response to scanning for observable radio signals at an observation position of a mobile device, wherein an access point identifier is contained in or represented by said at least one radio signal;
determining or causing determining, by the one or more processors, a strength of the at least one radio signal;
determining or causing determining, by the one or more processors, that the access point identifier substantially matches a point of interest (POI) identifier associated with a particular POI;
responsive to determining that the access point identifier substantially matches the POI identifier associated with the particular POI, determining or causing determining, by the one or more processors, a position estimate for said observation position at least partially based at least on one or more locations associated with the particular POI, wherein the position estimate is established relative to the particular POI based, at least in part, on the strength of the at least one radio signal; and
determining or causing determining, by the one or more processors, a confidence level of the position estimate, wherein the confidence level is based, at least in part, on visit frequency information associated with the particular POI.
