Your link is for wireless transmissions going through water. In this case, it’s still going through air.
It’s not the altitude or depth that matters, it’s the medium through which the signal goes. It will work just fine, from a technical standpoint.
That being said, wireless things are inherently unreliable compared to wired, and it’s stupid to make something so important not as reliable as possible.
Makes me want to pull out my 12” PowerBook G4. Those were some great computers.
