10. Call for Essential Patents
September 2007
Call for Essential Patents
Does anyone know of any patents of which the chair should be made aware, the implementation of which is either technically or commercially essential for either mandatory or optional portions of the standard, and for which a letter of assurance has not been submitted?
No notice of essential patents was made.
Bob O'Hara, Cisco Systems

Why are we here?
In 2004, the Wi-Fi Alliance began certifying WLAN equipment to the “Wi-Fi Multimedia” (WMM) specification.
WMM was drawn from an early draft of e
WMM evolved independently from e
WMM has derivative specs dependent on it, e.g. WMM U-APSD
Most everything being sold with QoS capabilities is certified to WMM
Bob O'Hara, Cisco Systems

13. Why are we here? In 2005, IEEE SA approved 802.11e
September 2007
Why are we here?
In 2005, IEEE SA approved e
802.11e is a superset of WMM, with technical differences
802.11e is now incorporated in (the standard)
All new amendments are made to the material in , e.g., n, r
New amendments increasingly diverge from what is being built and certified
Bob O'Hara, Cisco Systems

14. September 2007
Why are we here?
It can’t be good for the industry to have to develop two specs for the same functionality
One spec as the “official” standard, an amendment to
One spec as the “unofficial” standard, an amendment to WMM
We need to converge on a single specification that is acceptable to both IEEE and WFA
Alignment of the two organizations is the best path for the industry
Bob O'Hara, Cisco Systems

15. Areas not to be touched (from July session)
September 2007
Areas not to be touched (from July session)
Anything not in the scope of WMM, e.g., HCCA
Anything 11n is referencing, built on
DLS
4 transmit queues
Per channel access QD2 (PICS)
Advertisement (capabilities), preserving the structure
Bob O'Hara, Cisco Systems

16. Areas to be addressed (from July session)

Areas to be addressed (from July session)
07/1986r0 – Comparison of e and WMM
Areas in conflict between the two specs – in detail
Block ACK
Aggregation
Backward compatibility with WMM 1.1
U-APSD and the More Data bit
U-APSD behavior
Admission control
Sequence numbering
Information elements

18. September 2007
Scope Straw Man
This amendment incorporates some functionality from the Quality of Service specification developed as the Wi-Fi Alliance Wi-Fi Multimedia (WMM) specification version 1.1 into the standard.
This amendment does not deprecate any operational mode or feature introduced in e-2005 (or affect the compliance of devices adhering to e-2005).
It is specifically limited to incorporating functionality addressed in the WMM specification and the specification of behavior that is required to define operation with this new functionality.
Bob O'Hara, Cisco Systems

19. Additional Information Section
September 2007
Additional Information Section
Intent is to not necessarily incorporate all of the WMM specification.
Intent is to not deprecate existing functionality incorporated in e.
is not allowed to invalidate existing device compliance with e and will not deprecate any operational mode or feature introduced in e-2005.
Deprecate is understood to mean that functionality is not part of the standard, might continue to be described in a standard for backward compatibility, and its further use is discouraged. Deprecation is effectively removing something from the standard.
Specific areas addressed are differences in all information elements, unscheduled automatic power save delivery (U-APSD), sequence numbering, and admission control.
This amendment does not address the hybrid coordinated channel access (HCCA), extended distributed channel access (EDCA), or direct link setup.
Bob O'Hara, Cisco Systems

Straw Poll
Should we continue to develop a PAR and 5C related to the integration of WMM into ?
Yes: 21
No: 8
Abstain: 3

21. Note to second straw poll
September 2007
Note to second straw poll
It is possible that persons of like affiliation vote in a similar fashion because their individual positions on the issue coincide and not necessarily because they share an affiliation.
Bob O'Hara, Cisco Systems

22. Straw poll by affiliation
September 2007
Straw poll by affiliation
Should we continue to develop a PAR and 5C related to the integration of WMM into ?
Yes: 17
No: 3
Abstain: 5
This poll is taken by affiliation to attempt to ascertain if there is any domination of the process. This was requested by the chair.
The chair determines that the results are inconclusive.
Bob O'Hara, Cisco Systems

23. September 2007
Motion
Moved: the Study Group recommend to the Working group that the working group conduct an electronic ballot on the acceptability of the PAR and Five Criteria that was approved by the Study Group in the May 2007 meeting (document ). The Study Group would intend to resolve any comments received on the ballot with the goal of producing a revised PAR and Five Criteria during the November session.
Moved: Andrew Myles/Menzo Wentink
Chair rules that this is a procedural matter and not a motion.
Poll: 13/12/5 (procedural)
Chair rules that the recommendation will be forwarded to the working group, based on the poll of those present.
Bob O'Hara, Cisco Systems

24. September 2007
Point of Order
The LMSC P&P do not allow a letter ballot to be conducted by a study group or by a working group on behalf of a study group.
Ruling: the motion is not out of order, as the LMSC P&P are silent on the issue of conducting business in the working group by electronic means, other than the decision to forward a draft.
Bob O'Hara, Cisco Systems

25. Appeal to the decision of the chair
