I'm not sure where or why the English localization gave it this name. As far as I can tell, the japanese version just thinks of them as Communication Towers for radio/wireless transmission.

But...speaking of "Radio".
15 years prior, Glen Lodbrok, went on a geological survey mission that "failed" and then he "defected". There's some pretty big differences in the way English and Japanese scripts talk about it.

The mission was in "Rhadore", but it's spelling in Japanese is more like "Radiol". It's an island chain that's only seen in Ever Crisis. Ironically, they don't have radio there either, they communicate with smoke signals.
The person tasked with keeping the signals going is the "Eye of Rhadore" called Rosen. He has a dog too, named Refu.

Shinra of course wanted to build a Mako reactor there, their excavation causes monsters to attack. Sephiroth is there to save the day, and everyone...
