Abstract
The present technology provides an apparatus and a method for transmitting data via two or more FM signals in an interference avoiding manner. The apparatus comprises at least two FM transmitters. Each FM transmitter is configured to transmit a FM signal on a particular FM channel characterized by a certain carrier frequency that includes data and optionally one or more corresponding alternative frequencies (AFs). The apparatus further includes at least two receivers for receiving incoming electromagnetic radiation (EMR). At least one of the receivers is configured to receive incoming EMR associated with at least one of the FM channels, and another is configured to receive incoming EMR at least at frequencies outside of the FM channels. The controller is configured to separately control activation and deactivation of the FM transmitters and determine the carrier frequencies and the one or more AFs based upon incoming EMR.
