UTILIZATION OF LOCATION INFORMATION FOR IMPROVING TRUST MODEL FOR REAL TIME TRAFFIC AND TUNER FUNCTIONS

A method of validating a signal received by a radio from a radio station includes determining a strength of the signal as received by the radio, ascertaining a frequency of the signal, and calculating a first distance between the radio and the radio station dependent upon the strength of the signal as received by the radio. A location and a broadcast range of the radio station are found in a database based on the frequency of the signal, A second distance between the radio and the radio station is computed based on a known location of the radio and the location of the radio station as found in the database. The radio station is validated only if the first distance and the second distance are within a margin of error and if the second distance is within the broadcast range of the radio station.
