2. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 2 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

3. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 3 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 802.11b 802.11a coexistence with 802.16ab (2-10GHz unlicensed) UWB interference 6 th Criterion Going forward

4. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 4 Background 802.15 has TG2 coexistence group –802.11b and Bluetooth(TG1) coexistence 5GSG formed to investigate single global 5GHz standard –Coexistence issues between HL2 and 11a BWA (802.16) in unlicensed bands uses same spectrum as WLAN (802.11a) –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

5. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 5 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 ExCom on current or proposed IEEE standards in unlicensed bands –Similar in concept to FCC OET, which makes recommendations to the commissioners

6. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 6 Current Plans Keep 802.15 TG2 unchanged so they can continue working on their specific tasks at hand. Keep 802.11 5GSG 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”

7. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 7 Mission Statement Proposal: –The Coexistence Standing Committee studies the coexistence issues between IEEE802 wireless standards and makes recommendations to the IEEE 802 Executive Committee.

8. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 8 Functional Charter Proposal This SC is responsible for reviewing all proposed wireless PARs –The COEX SC generates a “guidance” report to ExCom relative to coexistence with published wireless standards and those in the development process (not a Recommended Practice) –This “guidance” report shall be used by ExCom 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 ExCom and a copy will be sent to the Chair of all other wireless WGs within IEEE802 –SC should begin work when the first WG ballot is published Preliminary report should be sent within 90 days

9. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 9 802 COEX Proposed Procedures Membership & Voting –SC Chair + chair of related WGs + rapporteurs –SC Chair breaks ties –SC Chair appointed by 802.0 for 2 year term –Rapporteurs appointed at the pleasure of the WG chairs Ratification of guidelines –>50% for internal recommendations –External recommendations not expected of this group, but would require 75% –The guideline is then presented to ExCom and the appropriate wireless WG(s)

10. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 10 Regulatory & Coexistence Complementary Charters Regulatory SC –Harmonize the IEEE 802 activities with the worldwide regulatory bodies Coexistence SC –Harmonize the IEEE 802 activities with the internal wireless WGs

11. doc.: IEEE COEX-01/010r0 Submission November 2001 Jim Lansford, Mobilian CorporationSlide 11 Next Steps Rules change for Standing Committee organization and voting Coordinate activity with the Regulatory to create a consistent message within ExCom –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)
