Serious question: do the FCC regulations on RF spectrum interference=20
extend beyond layer 1? I would assume that blasting a bunch of RF noise=20
would be pretty obviously out of bounds, but my understanding is that=20
the mechanisms described for rogue AP squashing operate at L2. The=20
*effect* is to render the wireless medium pretty much useless for its=20
intended purpose, but that's accomplished by the use (abuse?) of higher=20
layer control mechanisms.
I'm not condoning this, but do the FCC regulations RF interference=20
apply? Do they have authority above L1 in this case?
