To reduce confusion, no standard or task group was named 802.11l, 802.11o, 802.11x, 802.11ab, or 802.11ag.

802.11F and 802.11T are recommended practices rather than standards, and are capitalized as such.

802.11m is utilized standard maintenance, where 802.11ma completed 802.11-2007 and 802.11mb is expected to complete 802.11-2011.
