Goal Finalize proposal to SEC regarding
structure of proposed Standing Committee on
wireless coexistence, as well as initial tasks
for group to address

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)
• Going forward

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
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
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
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.

8
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

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 individuals 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)

10
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

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 cant be
  ratified here)

12
Presentations Discussion

• 802.15.4 Coexistence
• 5GHz WLAN BWA Coexistence

13
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
