TIL about the residents of a neighborhood complaining of mysterious ailments from a new cell phone tower. During a meeting the owner revealed that the tower had been off for over a month. Residents didn't show up to the followup meeting

Generally 30kHz - 1GHz is considered radio frequencies because some laws impose those limitations. Higher frequencies above that is considered microwave.

I've spent my entire career working on obscure radio systems. This is incorrect in a lot of ways. I have no idea where you came up with 30kHz - 1 GHz. That's extremely arbitrary. Additionally, the FCC regulates ALL radio transmissions... not just one weird, arbitrary radio band... ALL of it...

(That band you claimed is ALMOST the VHF + UHF radio bands... but UHF goes up to 3 GHz... so I really don't know what you're getting at.)

The Radio Spectrum covers 3Hz to 3,000 GHz.

Microwave is referring to a wavelength. That's it.

If you really get involved in radio, you'll even occasionally hear old radio dudes talk about the 1m (~300MHz) and 3m (~150MHz) bands.
