Why not just be honest, and let everyone know that the fate of (2.4Ghz)802.11a/b/g/n/ac residential/commercial/enterprise/carrier grade rests on an unencrypted management packet framework(that some may argue is defective-by-design).

Until 802.11ad implements alternative methods of handling client/station management, it only takes one deauthentication packet to cause client(s)/AP interference, and possible interception/eavesdropping.

No one is voting this up, but it's certainly interesting if true, or if I could actually understand it.
Wifi authentication frames aren't encrypted, so you can craft bogus de-auth packets to disconnect clients. This has a lot of uses - you can DoS a client indefinitely, force them to reveal a hidden access point when reconnecting, or force them to disconnect and then reconnect to a rogue access point.

new standards encrypt management frames, though.

802.11w adds encrypted management frames, but in practice this tends not to be a huge issue and not many vendors implement it yet.
Why did you specify 2.4Ghz? Is there something different about the 5Ghz protocols?
Perhaps, 4.9Ghz public safety should be taken into high consideration.
