Abstract
A method and apparatus for estimating the position of an electronic device. The method comprises receiving an observation comprising the identity of at least one wireless transmitter detected by the device at the position to be estimate, comparing the observation with the contents of a set of record, detecting respective first and second matches between the observation and records, and retrieving the corresponding positions. The method comprises estimating the position of the electronic device based on at least one of the first position estimate and the second position estimate, depending upon quality characteristics of the first match and the second match and indications of the sources of the respective records.
