2. November 2001
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

3. Agenda for Austin Meeting
November 2001
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
& 4 Coexistence with b
802.11a coexistence with ab (2-10GHz unlicensed)
Going forward
Jim Lansford, Mobilian Corporation

4. Background 802.15 has TG2 coexistence group
November 2001
Background
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. Statement of Purpose Purpose of the Study Group
November 2001
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

6. November 2001
Current Plans
Keep TG2 unchanged so they can continue working on their specific tasks at hand.
Keep GSG unchanged so they can continue working on their specific tasks at hand.
Keep 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

7. Mission Statement Proposal:
November 2001
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.
Jim Lansford, Mobilian Corporation

8. Functional Charter Proposal
November 2001
Functional Charter Proposal
This SC is responsible for reviewing all unlicensed band proposed 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
This does not affect existing coexistence TGs
Jim Lansford, Mobilian Corporation

9. 802 COEX Proposed Procedures
November 2001
802 COEX Proposed Procedures
Membership & Voting
Attendance at the 802 COEX meetings is open to registered member of , or
Voting at the 802 COEX meetings is limited to voting members of , or
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 ExCom and the appropriate wireless WG(s)
Jim Lansford, Mobilian Corporation

10. Regulatory & Coexistence Complementary Charters
November 2001
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
Jim Lansford, Mobilian Corporation

11. Next Steps Rules change for Standing Committee organization and voting
November 2001
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

12. Presentations & Discussion
November 2001
Presentations & Discussion
Coexistence
5GHz WLAN & BWA Coexistence
Jim Lansford, Mobilian Corporation

13. Wrapup ExCom should give direction on future of COEX SG this week
November 2001
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 reflector set up
