Organizational Issues

• Secretary selection Tim Blaney
• Vice chair tabled for now
• Liaisons
• 802.11 Stuart Kerry
• 802.15 Bob Heile
• 802.16 - David Chauncey

4
Tasks

• Statement of purpose (Recommend to ExCom how IEEE
  802 should address coexistence in existing and
  future specs)
• Summary of current standards where coexistence is
  an issue
• Activities already underway (e.g., 802.15.2)
• Possible ways ExCom can go forward
• Working Group (joint)
• Task Group (joint)
• TAG
• Recommended practice
• Output of SG (summary and report)
• Schedule

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 (New
  WG, Joint TG, TAG, etc)

6
Background

• When 802.15 became a Working Group it was
  required to Coexist with 802.11.
• This lead to the formation 802.15 Task Group 2 on
  Coexistence of WLAN and WPAN devices in
  unlicensed bands.
• Build a Coexistence Model
• Develop Coexistence Mechanisms

7
Background

• Recently 802.11 formed the 5 GHz Study Group
• Attempt to Harmonize all the 5 GHz WLANs
  (802.11a, HiperLAN2, MMAC) into a single
  worldwide 5GHz WLAN standard.
• At a minimum, ensure that the systems coexist.

8
Background

• Recently 802.16 formed the Wireless HuMAN Task
  Group
• Wireless Broadband Access in Unlicensed Bands

9
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.

10
Feedback?

• What is the role of this SG?
• Possible organizations going forward
• Working Group (joint)
• Task Group (joint)
• TAG won straw poll
• Recommended practice
• Output of SG (summary and report)
• Who works on the report?
• How/when do we meet/conf call?
• Schedule---is July realistic?

11
Meeting Summary

• Secretary/editor and liaisons chosen
• Straw poll indicated strong support for a
  Coexistence TAG
• CxSG will have initial conference call in two
  weeks
• Email distribution to attendees
• Will begin work on bylaws/operating rules
• Chair to research prior TAGs
• Will need to determine how TAG gets called in
• Correspondence will be sent to 11/15/17 liaison
• Separate reflector?
• Goal will be to have draft of operating rules by
  Portland
• Ratified by attendees
• Finalized and published thereafter

12
Conclusion

• Coexistence is becoming increasingly important in
  IEEE 802 wireless standards
• This study will recommend to ExCom the policies
  and procedures for future wireless standards
• Needs to be coordinated with ExCom regulatory
