Patent ID: 8571576

Claim:
An apparatus, comprising: at least one processor; at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: obtain a first set of valid geo-specific FM transmission parameters for a current geographical location of a user-portable device based on received global positioning satellite (GPS) data for the current geographical location of the user-portable device; provide signalling to configure an FM transmission circuitry to use the valid first set of geo-specific FM transmission parameters; determine a boundary between the current geographical location and a geographical location adjacent the current geographical location; obtain a second set of valid geo-specific FM transmission parameters for the geographical location adjacent the current geographical location while the user-portable device is in the current geographical location; track motion of the user-portable device while the user-portable device is in the current geographical location; and automatically provide signalling in response to the tracking the motion of the user-portable device, to configure the FM transmission circuitry to use the valid second set of geo-specific FM transmission parameters when the user-portable device is in, or crosses the boundary to, the adjacent geographical location.
