8 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems 6. Patents 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. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period. IEEE-SA Standards Board Bylaws on Patents in Standards Approved by IEEE-SA Standards Board – December 2002

16 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems A Short Refresher on Standards Development in 802.11

17 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems 50,000 foot view of the process Call for Interest (9.1.1) Study Group (9.1.2) Task Group (9.1.3) Working Group Ballot (9.1.4) Sponsor Ballot (9.1.5) Standards Board Approval (9.1.6) Publication (9.1.7) We are here Paragraph references are from 802.11 Policies and Procedures, 11-04/510r0 1 to 3 months 2 months to 1 year 2 months to 4 years 2 months to 1 year

18 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems How to write a draft 1.Write a proposal Describe in a MSWord document a list of “instructions to the editor” (aka “draft normative text”). For whole new sections, this will be 100% new text/figures. Create Powerpoint presentation based on above to describe salient details 2.Submit both docs to server at least 4 session hours before intent to vote on proposal The “4-hour rule” is part of 802.11 rules and is strenuously enforced Why? It gives people time to read, understand and consider the proposal TGT can also rule that longer period of time is required Helpful to announce existence of the documents through the reflector 3.Make presentation before the group 4.Make motion to accept proposal (the “draft normative text”) into the draft 75% majority required for any changes to a draft (additions/changes/deletions) If approved by group, editor will incorporate into the draft

19 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems Another way to write a draft Have an open discussion of some aspect of the draft Ask editor if the direction is clear If answer is “yes,” editor is empowered to make the necessary changes –Approve by a vote the outcome, expressed as a written motion ►Both methods are acceptable under the right circumstances!

20 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems 802.11 process for draft approval 802.11 Policies & Procedures 11-04/510r0, §9.1.4

21 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems What happens in Sponsor Balloting? Voters in the “Sponsor Pool”: –Review draft –Make comments –Vote Task Group must –Resolve these comments –Create revised draft –Submit for another round of review and voting Process follows similar flow chart as on previous slide Sponsor Ballot pool formed by WG chair from interested individual members of IEEE Standards Association (SA)

22 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems Rules about Drafts Offical drafts are owned by IEEE and available only to –Voting members (through http://grouper.ieee.org/groups/802/11/) http://grouper.ieee.org/groups/802/11/ –802.11 meeting attendees (http://www.802wirelessworld.com/), at the meeting onlyhttp://www.802wirelessworld.com In other words, you will need to be a voting member or come to the meetings to get current copies of the draft!

24 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems Straw Poll #1 Is the group in favor of accepting document 11-04/1203r1 as the starting point for the TGT draft, provided clauses 5,6,7,8 are deleted? Yes: 16 No: 0

25 doc.: IEEE 802.11-04/1389r3 Submission Nov 2004 C. Wright, Azimuth Systems Questions from IETF BMWG These questions will be considered in detail during a future telecon: –Minimize the radio-specific aspects of the testing, and hence minimize the variability of the results. The Signal to Noise Ratio Section (3.5.9) is primarily where the topic is addressed, - but there are other key points throughout Section 3.5 –Test Conditions. I'm interested to know if the committee members agree that the repeatability goal was achieved in Tom & Scott's draft
