Formation of IEEE n
It is expected that approval of the IEEE n PAR will be voted on by the IEEE 802 ExCom (Executive Committee) on July 25, 2003
The first official meeting of Task Group N is planned for September 15, 2003

HTSG
Until n receives official approval of its Project Authorization Request (PAR) from the ExCom, we will continue to do work under the HTSG charter
The HTSG charter has been extended through the May 2003 and July 2003 sessions
Top priority of HTSG should remain gaining PAR approval:
July Process comments from SEC and update as necessary
In the interim, HTSG can conduct business that helps progress the forthcoming TGn
Usage Model Special Committee
Channel Model Special Committee
General submissions

Stages of Standard Development
Project Authorization (PAR)
Anticipate approval in July 2003
Ideas, Procedures and Models
This is where HTSG can help TGn get a head start
Selection Stage
Execution of selection procedure
First Draft Approved and Forwarded to WG Ballot
Required support of 75% of members
Forward to Sponsor Ballot
Draft, having been polished via WG balloting, is forwarded to Sponsor Balloting pool
Sponsor Ballot pool is group of voters formed by the IEEE Standards Organization
Final Approval
Achieve when draft passes sponsor balloting, comments have been properly processed and the IEEE Standards Board approves the amendment

Items that must be completed before we officially start the n selection procedure:
Usage Models
Channel Models
Official Selection Procedure Adopted
Functional Requirements Adopted
Comparison Criteria Adopted
Draft Call for Proposals and/or Technical Contributions
Draft Press Announcement for Approval of n PAR
Publicity Committee and HTSG to have joint meeting on Thursday July 24, 2003 to review draft announcement from the Publicity Committee

Setting of usage models should affect the comparison criteria, functional requirements and PHY and MAC modeling
Eventually the comparison criteria, functional requirements, PHY and MAC modeling should be used in the selection procedure

7. Top Items for HTSG Early Consideration (1/2)
July 2003
Top Items for HTSG Early Consideration (1/2)
Usage Models
Is important to start sharing ideas on usage models and technologies
Presentations on usage models and what n should be are encouraged
Usage models should affect the selection procedure, channel and MAC models, comparison criteria and functional requirements
Channel Modeling

8. Top Items for HTSG Early Consideration (2/2)
July 2003
Top Items for HTSG Early Consideration (2/2)
Official Selection Procedure
Need to think this through very carefully considering:
Past success and failures of other Task Groups
Difference between PARs of previous Task Group and TGn
The size of TGn
Procedure must be fair
Procedure should be deterministic
Procedure should encourage scientific decision making
Procedure should encourage cooperation among members
Matthew B. Shoemake, TGn Chair Elect

9. Adoption of HTSG Actions by TGn
July 2003
Adoption of HTSG Actions by TGn
All “early” work done by HTSG will need formal approval/ratification by TGn
In an effort to maximize our efficiency, it is encouraged to work inside HTSG with due diligence and commitment, such that any work that is completed by HTSG can be adopted with no or minimal modification by TGn
Likewise, for any work not completed by HTSG, it is desirable that TGn be able to pick this work up and continue rather than starting over
Matthew B. Shoemake, TGn Chair Elect

10. July 2003
Selection Procedure
Propose that we kick off discussion on selection procedure during July 2003 session:
Review selection procedures of g and a
Take straw polls to determine what the simple majority supports
Use the results of the straw polls to draft the IEEE n Selection Procedure
Have three conference calls just before the September 2003 session to refine the draft
Tentatively August 27, September 3 and September 10
Bring the draft to the September 2003 session for further review, modification and ultimate adoption
Matthew B. Shoemake, TGn Chair Elect

11. Previously Used Selection Procedures: 802.11g
July 2003
Previously Used Selection Procedures: g
802.11g procedure drew from the b procedure
802.11g procedure has been leveraged by h and a
Selection Procedure ( r3):
Functional Requirements ( r4) must be met to be considered by the TGg
Comparison Criteria ( r9) are questions that must be answered by each proposer to be considered by TGg
No scoring system and members free to vote at will
Issue with g procedure:
Step 19 was not very clear, and at a critical stage of the process, there were varying interpretations of the process
a attempted to fix this problem
Matthew B. Shoemake, TGn Chair Elect

12. Previously Used Selection Procedures: 802.15.3a
July 2003
Previously Used Selection Procedures: a
IEEE a built on g procedure and has attempted to plug holes and remove any ambiguities
Selection Procedure (doc ):
Added very clear flow chart for procedure
IEEE a procedure includes:
“Technical Requirements” (doc )
“Selection Criteria” (doc )
Low hurdle vote: > 20%

Straw Polls (1/3)
Results of the straw polls to draft the IEEE n Selection Procedure.
What should be used as a baseline for the n Selection Procedure?
802.11g Selection Procedure YES/NO
a Selection Procedure YES/NO
Other: ___________
Should n define Functional Requirements that must be met for proposal consideration:
YES/NO
Should n definite Comparison Criteria that must be addressed/answered for a proposal to be considered:

Straw Polls (2/3)
Results of the straw polls to draft the IEEE n Selection Procedure.

YES/NO
If so, what should the low hurdle level be?
Greater than 20 %
Greater than 25 %

15. July 2003
Straw Poll (3/3)
Results of the straw polls to draft the IEEE n Selection Procedure.
In the event that one proposal remains, but has not achieve 75% support shall the procedure call for:
a model:
“No voters” must state objections
Remaining proposer allowed to address objections, one more vote taken
If 75% not reached on that vote, go back to in procedure and reinstate last three proposals
802.11g model:
Indefinite voting on remaining proposal as long as its support does not fall below 33 1/3 %
Other
When shall the group be able to change the procedure?
