IEEE 802 Wireless Coexistence Study GroupNovember Plenary Meeting Jim Lansford Chair, IEEE 802 Coexistence Study Group Jim.Lansford@mobilian.com (405) 377-6170 Jim Lansford, Mobilian Corporation
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 Jim Lansford, Mobilian Corporation
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 • 6th Criterion • Going forward Jim Lansford, Mobilian Corporation
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 Jim Lansford, Mobilian Corporation
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 Jim Lansford, Mobilian Corporation
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” Jim Lansford, Mobilian Corporation
Mission Statement • Proposal: • The Coexistence Standing Committee studies the coexistence issues between IEEE802 wireless standards and makes recommendations to the IEEE 802 Executive Committee. Jim Lansford, Mobilian Corporation
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 Jim Lansford, Mobilian Corporation
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) Jim Lansford, Mobilian Corporation
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 Jim Lansford, Mobilian Corporation
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) Jim Lansford, Mobilian Corporation
Presentations & Discussion • 802.15.4 Coexistence • 5GHz WLAN & BWA Coexistence Jim Lansford, Mobilian Corporation
Wrapup • ExCom 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 Jim Lansford, Mobilian Corporation
