Well, to pick some nits, if radio waves didn't work the same way, that would be a pretty fundamental shift in physics, to the point of throwing all our assumptions out the window about our observational evidence.

We're assuming they communicate the same way we would.

I'll make up something scifi like. On planet x they use short term Seismic wave to move data around. How would we on earth ever pick that up
