Description

IEEE 802.11 Working Group

WG

The Working Group is comprised of all of the Standing Committees, Task Groups, Study Groups, and Ad-Hoc Groups.

Membership is at the WG level.  All WG members may participate in any of these sub-groups.

Task Group

TG

The committee(s) that are tasked by the WG as the author(s) of the Standard or subsequent Amendments via an approved PAR

Study Group

SG

A committee responsible for researching a possible future amendment.  The output of the SG is usually a project authorization request (PAR).    

Study groups are authorized by the IEEE 802 executive committee (EC) and are expected to have a relatively short lifetime (~6 months). 

The SG terminates when it has submitted a PAR,  or failed to gain approval for a PAR,  or when the IEEE 802 EC declines to approve an SG extension.

Standing Committee

SC

A committee with a determined role/task, that does not modify the IEEE 802.11 standard.  These committees are created by the 802.11 chair and are relatively long-lived.

Ad-hoc Committee

AHC

A committee with a determined role/task, that does not modify the IEEE 802.11 standard.  These committees are created by the 802.11 chair and are relatively short-lived.
