Abstract
An apparatus for location identification using broadcast wireless signal signatures includes a receiver to receive first measurements of a plurality of wireless television signals. The first measurements are made by a remote device receiving the plurality of wireless television signals. In addition, the apparatus includes a processor to select one or more of a plurality of possible locations of the remote device based on the first measurements and a plurality of associations each associating one of the possible locations with expected values. Moreover, the receiver receives second measurements of the wireless television signals made by one or more monitor units, and the processor generates the expected values for the first measurements and the associations based on the second measurements and the locations of the one or more monitor units.
