There's a lot of amateur lawyering ogain on in this thread, in an area where there's a lot of ambiguity. We don't even know for sure that what Marriott did is illegal -- all we know is that the FCC asserted it was and Mariott decided to settle rather than litigate the matter. And that was an extreme case -- Marriott was making transmissions for the *sole purpose of preventing others from using the spectrum*.
I don't see a lot of ambiguity in a plain text reading of part 15. Could you please read part 15 and tell me what you think is ambiguous?
Marriott was actually accused of violating 47 USC 333: No person shall willfully or maliciously interfere with or cause interference to any radio communications of any station licensed or authorized by or under this chapter or operated by the United States Government.
In cases like the Marriott case, where the sole purpose of the transmission is to interfere with other usage of the transmission, there's not much ambiguity. But other cases aren't clear from the text.
For example, you've asserted that if I've been using "ABCD" as my SSID for two years, and then I move, and my new neighbor is already using that, that I have to change. But that if, instead of duplicating my new neighbor's pre-existing SSID, I operate with a different SSID but on the same channel, I don't have to change. I'm not saying your position is wrong, but it's certainly not clear from the text above that that's where the line is. That's what I meant by ambiguity.
I've watched this discussion with much amusement. In a manner similar to our legal system, where a lot of the law is actually defined by what is commonly called "case law", most of the non-radio geeks here are talking about radios and spectrum as though all of this represents some sort of new problem, when in fact the agency tasked with handling it is older than any of us.
(What's your position on a case where someone puts up, say, a continuous carrier point-to-point system on the same channel as an existing WiFi system that is now rendered useless by the p-to-p system that won't share the spectrum? Illegal or Legal? And do you think the text above is unambiguous on that point?)
It doesn't matter if you think your quoted text on this point is ambiguous. The fact of the matter is that decades of policy are that the FCC decided many years ago that you cannot go onto shared, unlicensed spectrum with a powerful transmitter and hold the mic open with the intent to disrupt the legitimate communications traffic of others on that channel. This logically derives fairly straightforwardly from the quoted text, and the fact that wifi deauth interference is merely a packet-pushing variant of this isn't really hard for the average person to extrapolate. But they also have decades of experience with other aspects of more subtle radio shenanigans, and they have the authority to sort it all out, so what we should really be hoping for is that the FCC doesn't do something onerous like mandate registration of access point MAC's and SSID's if and when it gets to a point where it is considered a true problem. That could well be the regulatory "solution" to your ABCD problem, but it would be a heavyhanded fix to a minor problem. ...
