November 2001 doc. : IEEE COEX-01/010 r 0 IEEE 802 Wireless Coexistence Study Group November Plenary Meeting Jim Lansford Chair, IEEE 802 Coexistence Study Group Jim. Lansford@mobilian. com (405) 377 -6170 Submission 1 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Meeting Schedule Goal: Finalize proposal to SEC regarding structure of proposed “Standing Committee” on wireless coexistence, as well as initial tasks for group to address Submission 2 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Agenda for Austin Meeting • • Background Review of “Statement of Purpose” Review of activities to date Objectives for meeting – Rules change for Standing Committee – Some coexistence issues for future SC work • 802. 15. 3 & 4 Coexistence with 802. 11 b • 802. 11 a coexistence with 802. 16 ab (2 -10 GHz unlicensed) • Going forward Submission 3 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Background • 802. 15 has TG 2 coexistence group – 802. 11 b and Bluetooth(TG 1) coexistence • 5 GSG formed to investigate single global 5 GHz standard – Coexistence issues between HL 2 and 11 a • BWA (802. 16) in unlicensed bands uses same spectrum as WLAN (802. 11 a) – Regulations allow both – Indoor vs. outdoor restrictions • This SG has met twice (Orlando & Portland) • SG charter officially expires at this meeting • EXCOM will need to approve continuance Submission 4 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Statement of Purpose • Purpose of the Study Group – Define the functional charter of this new group to best address the wireless coexistence issues. – Recommend an organization to best accomplish – Goal is to have a group that can review and make coexistence recommendations to Ex. Com on current or proposed IEEE standards in unlicensed bands – Similar in concept to FCC OET, which makes recommendations to the commissioners Submission 5 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Current Plans • Keep 802. 15 TG 2 unchanged so they can continue working on their specific tasks at hand. • Keep 802. 11 5 GSG unchanged so they can continue working on their specific tasks at hand. • Keep 802. 16 unchanged. • This SG is only addressing new standards or existing standards not covered by a current WG/TG – This SC would not try to develop a recommended practice document – A recommended practice document would require a separate PAR • Current proposal to EXCOM is for a new entity called a “Standing Committee” Submission 6 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Mission Statement • Proposal: – The Coexistence Standing Committee studies the coexistence issues between wireless standards in the unlicensed frequency bands and makes recommendations to the IEEE 802 Executive Committee. Submission 7 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Functional Charter Proposal • This SC is responsible for reviewing all unlicensed band proposed PARs – The COEX SC generates a “guidance” report to Ex. Com relative to coexistence with published wireless standards and those in the development process (not a Recommended Practice) – This “guidance” report shall be used by Ex. Com as a technical expert opinion for evaluating a proposed PAR to develop a Recommended Practice, if needed • This SC is responsible for generating a final review report of the Draft Standard prior to Sponsor Ballot – This report will be presented to the sponsoring WG and Ex. Com and a copy will be sent to the Chair of all other wireless WGs within IEEE 802 This does not affect existing coexistence TGs Submission 8 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 802 COEX Proposed Procedures • Membership & Voting – Attendance at the 802 COEX meetings is open to registered member of 802. 11, 802. 15 or 802. 16 – Voting at the 802 COEX meetings is limited to voting members of 802. 11, 802. 15 or 802. 16 – Attendance at 802 COEX meetings will count towards attendance at the individual’s primary WG • Ratification of guidelines – A guideline requires a 75% approval vote by the members of the 802 COEX as outlined above – The guideline is then presented to Ex. Com and the appropriate wireless WG(s) Submission 9 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Regulatory & Coexistence Complementary Charters • Regulatory TAG – Harmonize the IEEE 802 activities with the worldwide regulatory bodies • Coexistence TAG – Harmonize the IEEE 802 activities with the internal wireless WGs relative to unlicensed bands Submission 10 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Next Steps • Rules change for Standing Committee organization and voting • Coordinate activity with the Regulatory to create a consistent message within Ex. Com – The Regulatory SC is an outwardly focused activity targeted at influencing decisions of the worldwide regulatory agencies relative to IEEE 802 desired directions – The Coexistence SC is an inwardly focused activity targeted at coordinating coexistence issues within and between the various wireless WGs in IEEE 802 • Motion to extend? (Rules change likely can’t be ratified here) Submission 11 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Presentations & Discussion • 802. 15. 4 Coexistence • 5 GHz WLAN & BWA Coexistence Submission 12 Jim Lansford, Mobilian Corporation

November 2001 doc. : IEEE COEX-01/010 r 0 Wrapup • Ex. Com should give direction on future of COEX SG this week • Coexistence SC would have a number of tasks to do! • Need to get web site and email reflector set up Submission 13 Jim Lansford, Mobilian Corporation
