Not only that, the newer WiFi standards are doing away with the dissociation attacks (which is what they are) that some vendors had been selling as "containment" because they're also quite obviously a denial of service attack vector.
You can imagine what happens when two corporations are in adjacent spaces in the same building and both have their WiFi configured to "contain" the neighboring tenant's access points.
> You can imagine what happens when two corporations
I don’t need to imagine, I’ve done it to my apartment complex before by mistake. I have an Aruba 3200XL controller and a bunch of APs (couple 335s, couple 225s, and some older 105s, with the 105s being used as Air and Spectrum monitors). Decided to see the impact and quickly learned all my neighbors lost WiFi access.
