In the worst case scenerio of regulatory domain intersections
between a different set of regulatory rules you will end up
without being able to initiate radiation on any frequency
range. Provide a hint as to what needs to be done next in
order to actually build a useful regulatory domain. Currently
we do this manually but building the mathematics would be
even more useful as we grow usage of the spectrum.
