An example of efficient spectrum management: army tactical radio operations in broadcasting bands

An overview of the methodology used to accommodate army tactical radio operations in broadcasting bands is presented. A detailed electromagnetic compatibility (EMC) analysis was carried out to maximize the spread spectrum operation of army tactical radios in Canadian bases, while minimizing the interference potential to the reception of TV and EM radio broadcast signals outside the bases. In Canada, the radio's tuning range of 30-108 MHz spans broadcast, land mobile and other bands. The details of the EMC study involved laboratory determination of broadcast receiver response to frequency hopping transmissions, the design of the appropriate EMC analysis algorithms, and the applications of specially prepared computer programs to obtain interference-free operation parameters for the military radios.
