Notice: This document has been prepared to assist IEEE It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.
Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE
Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE Working Group. If you have questions, contact the IEEE Patent Committee Administrator at

Non-AP Scenario IV
First responder (fire, police, EMS) radios.
Need the improved range and connectivity afforded by mesh but there is just no reason for a Fireman’s walkie-talkie to be an Access Point.

Another Factor
Beacon Bloat
Requiring Mesh Points to be Access Points tends to imply that all required AP Beacon / Probe Response fields must appear in Mesh Point Beacons / Probe Responses.
For further discussion of this factor, see “Specific or Universal Beacons?”, Guido Hiertz, 11-07/403r0.

Vote on PAR Amendment
The exact text of the proposed PAR and 5 Criterion amendment is in 11-07/149r5 with changes tracked from the documents currently in effect.
It implements the change discussed above.
Generally change Access Point to Station.
Delete ESS.
It brings a few dates and references up to date.
Otherwise, it tries to make minimal changes.
At the poorly attended closing plenary session in London, this document had broad support but failed by exactly one vote to get the required 75%.
TGs continues to believe this amendment should be adopted by the Working Group and plans to bring it up at the closing plenary this session.
