Potential RF interference to control links of small unmanned aircraft

The control links of small unmanned aircraft (UA) systems (UAS) typically operate in the 72–73, 902–928, and 2400–2483.5 MHz bands. They share those bands with many radio-frequency (RF) emitters that expose the links to the possibility of RF interference (RFI) and resultant control link interruptions. In this analysis we quantitatively assess the potential interference levels to which such links may be subjected.
