IEEE 802.11 Standards and Specifications

Below lists the IEEE 802.11 Standards / Specifications as well as their purpose:

IEEE 802.11a 54Mbps 5GHz standard.
IEEE 802.11b Enhancements to 802.11 to support 5.5Mbps and 11Mbps.
IEEE 802.11c Bridge operation procedures. Included in the IEEE 802.1d standard.
IEEE 802.11d International (country-to-country) roaming extensions.
IEEE 802.11e Enhancements to 802.11 – Quality of Service. Including packet bursting.
IEEE 802.11F Inter-Access Point Protocol.
IEEE 802.11g 54Mbps 2.4GHz standard. Backward compatible with 802.11b.
IEEE 802.11h Spectrum Managed 5GHz 802.11a – Dynamic Frequency Selection (DFS) and Transmit Power Control (TPC).
IEEE 802.11i Wi-Fi Protected Access 2 (WPA2) for enhanced security (authentication and encryption). Also referred to as Robust Security Network (RSN).
IEEE 802.11j Extensions for Japan and US public safety.
IEEE 802.11k Enhancements to 802.11 – Radio Resource Management (RRM).
IEEE 802.11m Maintenance of the standard, odds and ends.
IEEE 802.11n Higher throughput improvements using Multiple Input, Multiple Output (MIMO) antennas.
IEEE 802.11p Wireless Access for the Vehicular Environment (WAVE) for vehicular environments, eg: ambulances and passenger cars.
IEEE 802.11r Fast roaming.
IEEE 802.11s Extended Service Set (ESS) Mesh Networking.
IEEE 802.11T Wireless Performance Prediction (WPP).
IEEE 802.11u Internetworking with non-802 networks, eg: cellular networks.
IEEE 802.11v Wireless network management.
IEEE 802.11w Protected Management Frames.
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.
