That sounds relatively simple. One problem might be that on a spectrum
analyzer, a set of WiFi-looking signals, a few tens of MHz from where WiFi
ought to be, would stick out like a sore thumb.
The large majority of airport-visiting people have cell phones, and many of
them will be accessing WiFi at any given time. It seems to me that anybody
attempting to control a drone secretly might want to "hide in plain sight",
using an existing WiFi system.
