Abstract

In a wireless communication system which may include a mobile device having an integrated FM radio transmitter and a FM radio receiver, a geographic location of the mobile device may be determined. A FM channel map may be determined based on the location and the FM radio transmitter may be configured for transmitting FM signals based on the FM channel map, which may include a list of ranked FM channels. The geographic location may be acquired from received RDS or RBDS signals, received GPS signals, other received wireless signals, and/or from user data. Channel spacing, channel offset and/or frequency band may be determined for the FM channel map. A frequency for transmitting FM signals via the FM radio transmitter may be selected based on the determined FM channel map. The FM radio receiver may also be configured for receiving FM signals based on the determined FM channel map.

Claims
