Legal if the building is constructed such that the radio signals required cannot get in or out due to the materials used, like a giant farraday cage.
The FCC does not have the authority to stop you from doing that.
Their authority is in the area of regulating who can USE the airwaves.... they regulate who can broadcast, and how.
And in this case, they are saying that building a device that actively transmits with the intention of preventing other devices from working is illegal.
Private property is irrelevant - the airwaves are public.
Specifically, the ISM (Industrial, Scientific, Medical) bands, that common WiFi operates on, are open to use by anyone, and you can't interfere with anyone else's use of them.
Alternatively, you can license (effectively, lease) your own little slice of spectrum from the FCC, and then it's ‘yours’, and then you don't have to use forged packets to stop other people using it — the FCC will slap them for you.
I thought exactly the same. Why they're using ISM band which is free to use, if they want reliable networks they should use such band in the very first place.
