AAR Frequency Coordination

AAR Frequency Coordination is an FCC-Certified Frequency Coordinator, providing FCC licensing and Frequency Coordination services in the Private Land Mobile Radio (PLMR) spectrum. Our office is located at the Transportation Technology Center, Inc. (TTCI) in Pueblo, Colorado. TTCI is a wholly owned subsidiary of the Association of American Railroads. Our staff is knowledgeable of the FCC Rules and Regulations and can assist you with your FCC two-way radio licensing needs from start to finish. We use state of the art propagation and application management software.  We are certified to coordinate frequencies in the General Business Pool (470-512 MHz band), and are the only FCC-designated Frequency Coordinator for coordination of the railroad frequencies (160.215-161.610 MHz and some 452 and 457 MHz band frequencies).  AAR Frequency Coordination can also assist you with applications for other frequencies in cooperation with the Automobile (LA), Petroleum (IP), Power (IW) frequency coordinators.
