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

5. Abstract
The presentation summarizes the WWiSE complete proposal, in the context of the first downselect vote
Sean Coffey, Texas Instruments, et al.

6. State of the Task Group
The Task Group will soon, in March, have to make an irrevocable decision that will have significant consequences for the success or failure of the entire project
This decision is not whether to choose WWiSE, or TGnSync, or MitMot
The irrevocable step is the enabling of the first draft of TGn
Sean Coffey, Texas Instruments, et al.

7. State of the Task Group, contd.
Any items in the first draft that are unspecified, or undecided, can only be corrected by a 75% majority of the entire Task Group, under formal Robert’s Rules of Order proceedings
In 2001, there were minor mechanisms in the .11e draft that were generally agreed to be broken, but the proceedings deadlocked for 6 months because of the 75% hurdle
.11e is still in progress, now up to draft 12
Sean Coffey, Texas Instruments, et al.

8. Suitability as basis for first draft
The current TGnSync specification is not in adequate state to form a first draft
Massive technical inconsistencies
Some on the order of 10 dB or more, even within TGnSync simulations
Very sophisticated techniques with severely underspecified mechanisms
Descriptions to support closed loop either inadequately described or not described at all
Disjointed features rather than consistent design
Further major changes pending due to mergers
Sean Coffey, Texas Instruments, et al.

9. Purpose of the vote
The primary significance of this vote is for the Task Group to offer feedback on preferred direction
The final decision will be in March
The final opportunity for feedback is now
Choices:
WWiSE
TGnSync
MitMot
Not vote
Sean Coffey, Texas Instruments, et al.

10. WWiSE as draft 1.0 of .11n
The WWiSE specification, r6, is ready for immediate use as the basis for draft 1.0 and submission to WG letter ballot
The mechanisms are well suited for all extensions, including beamforming and closed loop feedback, multiple backward compatibility mechanisms, and also give significant advantages in range, coverage, and robustness
The core of WWiSE is an efficient embodiment of items that are mostly in general agreement
Sean Coffey, Texas Instruments, et al.

11. Conclusion
The WWiSE specification will enable the Task Group to progress efficiently to finish the .11n amendment and facilitate rapid market development of High Throughput technology
