Automated Frequency Deconfliction for Tactical Networks

As tactical battlefield communication becomes more complex, the efficient use of spectrum becomes increasingly difficult. Automated tools can be used to apply algorithms that aid in the rapid identification of frequency conflicts and the results can then be used to suggest or assign frequencies that are deconflicted. Techniques in commercial cellular networks address minimizing interference from frequency reuse when frequency channels are assigned to base stations. Additionally, interference from intermodulation products, harmonic interference and adjacent channel leakage contribute to frequency conflicts. A method is proposed for extending automated frequency planning techniques in commercial networks so that they work with deconfliction and assignment in tactical networks. A sample application of the method demonstrates that controlled quality-capacity tradeoffs can be achieved even for highly non-uniform networking scenarios
