3. Opening remarks • Registration • Please sign in on the paper sign-in sheet • Electronic registration MAY be working • Paper is our backup • Server has all prior documents • ieee802/802-18-19/coexistence • Today’s docs are (temporarily) on 802-18-19/submissions/802-19/May03 • March, January, November are also there • Email reflector majordomo • subscribe stds-802-19 <your_address> • Currently at 92 subscribers • Web site • www.ieee802.org/19 • Continually being upgraded…thx to Ian Gifford Jim Lansford, Mobilian

4. Background • Study group organized in July 2001 • TAG created in July 2002 • Does not impact existing Coexistence TGs • 802.15.2 continues • 802.16 continues • Complementary with 802.18 • The Regulatory TAG is an outwardly focused activity targeted at influencing decisions of the worldwide regulatory agencies relative to IEEE 802 desired directions • The Coexistence TAG is an inwardly focused activity targeted at coordinating coexistence issues within and between the various wireless WGs in IEEE 802 • External messaging of coexistence policies • TIA liaison for cordless phones • Possible EMC liaison Jim Lansford, Mobilian

5. Proposed agenda for meeting Jim Lansford, Mobilian

6. Status/Summary • Web site and reflector up • Approx 10 attendees at interim meeting in Dallas • Minutes are in 03/010 • Charter and Operating Rules voted on by letter ballot between sessions • Documents PASSED 8/2/0 (procedural, not technical) • Will try to clean up no votes and recirculate, even though not required • Guideline document drafted by Mat Sherman • Liaisons had two conference calls and generated two revisions • Current document is 03/007r3 • Engaged with 802.15.3a process – presentation at March meeting • Engaged with 802.11n (HTSG) process – presentation at March meeting Still need a Vice-Chair!! Jim Lansford, Mobilian

7. Plans for Dallas • Review letter ballot • Vice chair • Presentation in 802.11n • Review coexistence criteria from prior 802.19 • Continue work on Coexistence Guideline document (Mat Sherman’s) 03/007 • Preparation for presentation in 802.15.3a • Begin reviewing first 24 proposals • Discussion of further upcoming work Jim Lansford, Mobilian

8. Charter and operating rules • Documents: • 03/001r2: Charter • 03/002r2: Operating rules • Approved 8/2/0 • Goes to SEC in July • Two no voters had good comments, so will incorporate and recirculate • Will edit now… Jim Lansford, Mobilian

9. Coexistence Guide Document • Document 03/007 • Detailed listing of policies and procedures for 802.19 • Planned completion by July Jim Lansford, Mobilian

10. Role of 802.19 in 802.15.3a selection • Proposals in March, revisions this week • After the session, 802.19 will hold an ad-hoc meeting with the 802.15.3a proposal manager, Ian Gifford • Mandatory coexistence sections will be lifted from each proposal for circulation within 802.19 • We will begin work today • Summary will be presented at joint session in San Francisco • 802.19 will take up review and comment on this combined document in July • Position paper will be up for approval in September or November Jim Lansford, Mobilian

11. Role of 802.19 in 802.11n (HTSG) • Review PAR/5 Criteria • Process continues as in 15.3a • Current versions do not constrain frequency band or discuss coexistence mechanisms • Once TG is created, 802.19 will engage more fully Jim Lansford, Mobilian

12. Review of 802.15.3a proposals • Team 1: • Intel • Time Domain • Discrete Time • General Atomics • Wisair • Philips • FOCUS Enhancements • Samsung • Team 2 • Extreme Spectrum • Motorola • TI • Others Jim Lansford, Mobilian

13. Future tasks of 802.19 • Final approval of charter and operating rules by SEC • Continue 802.15.3a engagement • Continued review of proposals as amended • Publish • Continued involvement with PAR/5 Criteria development within 802.11n (HTSG) • Other possible: • Appendix for 802.15.2 for 802.11g • TIA cordless phone coexistence • Spectrum etiquette with 802.18 Jim Lansford, Mobilian

14. Summary • Thanks for your attendance • Feedback always appreciated • Make sure you sign the paper log Jim Lansford, Mobilian

15. Backup Jim Lansford, Mobilian

16. Proposed Charter (1) • IEEE 802 Coexistence Technical Advisory Group (TAG) is responsible to recommend and maintain the IEEE 802 policy regarding coexistence among implementations of IEEE 802 and other standards. • To offer, when required, assessments to the SEC regarding the degree to which standards developers have conformed to coexistence criteria. • To develop coexistence documentation of interest to the technical community outside 802. • To assist, when requested by a Working Group running a ballot, with evaluation of proposals during the downselection process. Jim Lansford, Mobilian

17. Proposed Charter (2) • To assist, when requested by a Working Group running a ballot, with the resolution of comments related to coexistence. • To issue reports and recommendations to the SEC representing a balanced viewpoint regarding impending SEC actions in which coexistence may be a concern. • Approved per COEX-TAG, relevant Working Group, and LMSC rules. (see LMSC Rules, Procedures 3 and 4.) • To develop and maintain IEEE Standards (either Recommended Practices or Guides) to foster coexistence within the communications industry, provided that such work is done under an approved PAR. • The Coexistence TAG may recommend additional activities consistent with its Purpose Statement, subject to approval by the SEC. Jim Lansford, Mobilian

18. Operating Rules Discussion • The original thoughts • Where we go from here • Formal documentation Jim Lansford, Mobilian

19. Original Concepts • TAG reviews PAR/5 Criteria • Includes coexistence language • Stresses need for coexistence as an evaluation criterion • Coexistence Guideline document will have more details • TAG Reviews Draft at letter ballot • Group solicits comments across 802.19 voters • Can be from all working groups • 802.19 will vote to endorse or not endorse a draft, with comments • Coexistence vote and comments delivered to SEC at or before Sponsor Ballot Jim Lansford, Mobilian

20. Modifications to procedure • 802.19 appears to be also a facilitator • Joint sessions with WG/TG to air specific coexistence presentations • Conference calls to help converge to selection criteria • Ad hoc meetings to help identify and resolve issues Jim Lansford, Mobilian

21. Formal Documentation • See document 03/002 • Modeled after 802.3 rules • Uses “standard” LMSC template • Modified for TAG • TAG cannot write standards (per LMSC rules), only “Guidelines” and “Recommended Practices” • Must also be ratified by SEC Jim Lansford, Mobilian
