  7. A Short Refresher on Standards Development in 802.11 C. Wright, Azimuth Systems

  8. 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) 50,000 foot view of the process Paragraph references are from 802.11 Policies and Procedures, 11-04/510r0 We are here 2 months to 1 year 2 months to 4 years 2 months to 1 year 1 to 3 months C. Wright, Azimuth Systems

  9. How to write a draft • 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 • 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 • Make presentation before the group • 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 C. Wright, Azimuth Systems

  10. 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! C. Wright, Azimuth Systems

  11. 802.11 process for draft approval 802.11 Policies & Procedures 11-04/510r0, §9.1.4 C. Wright, Azimuth Systems

  12. 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) C. Wright, Azimuth Systems

  13. Rules about Drafts • Offical drafts are owned by IEEE and available only to • Voting members (through http://grouper.ieee.org/groups/802/11/) • 802.11 meeting attendees (http://www.802wirelessworld.com/), at the meeting only • In other words, you will need to be a voting member or come to the meetings to get current copies of the draft!
