Abstract:A key element of AZTech's mission is to make up-to-the-minute traffic information available to virtually any traveler. In pursuit of this goal, AZTech set its sights on obtaining an FM subcarrier that could transmit a wide variety of traffic-related information to mobile wireless devices on a timely basis. A subcarrier is the portion of FM radio waves that aren't required to broadcast a radio station's audio signal. Although FM subcarriers make up a small proportion of the broadcast frequency, they represent a significant source of revenue for radio stations, as numerous pager companies rent the subcarriers to transmit their signals. For this reason, few stations offer their moneymaking subcarriers to other interested parties.
