Patent Policy
Questions were raised by members on the patent policy. They were directed to consult with David Law (PatCom chair) and their legal counsel.
Bob O'Hara, Cisco Systems

10. Call for Essential Patents
July 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 announced by any member.
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
July 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. July 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 Anything not in the scope of WMM, e.g., HCCA

Areas not to be touched
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

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.

Motion
Moved: to approve the following scope statement:
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.

Result: 25/14/7 Fails

23. Additional Information Section
July 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.
