IEEE 802.11y	3650–3700 operation in the US.
IEEE 802.11z	Extensions to Direct Link Setup (DLS).

The IEEE project naming convention uses upper-case letters (eg: 802.1Q) to identify standalone standards, and lower-case letters to identify amendments (previously known as supplements) to existing standards. There should never be 2 projects differing only in the case of letters!

The REV notation (eg: 802.1Q-REV) is used to identify a revision of an existing standard, which has more extensive changes to the existing standard than an amendment. Previously, revisions also had their own project names.
