Lunch 12-115pm
Review of the Technology Selection Process Contribution 46 continued.
Contribution by Dan Gal on “Technology Selection Process Procedure” C802.2005/72r5
This is an update to contribution r4 that was discussed in the May 2005 session. There
was debate about whether all issues raised previously have been addressed in this update.
Ina an effort to create better consensus, the Chair offered to work with the contributor and
others to identify issues where there is agreement, and issues where there is
disagreement. The chair also offered to make a contribution with this list of issues.
Following a further discussion on next steps for progress the Technology Selection
Process document, a Motion was made to use Contribution 46 as the baseline document
for the Technology Selection Process with Mark Klerer as acting editor.
Agreed by unanimous consent.
Contribution by Jim Ragsdale on “Proposed Technology Description Template”
C802.20-05-35.
This is a proposed template that is part of the documents that shall be turned in by the
proponent. There were some comments about needed changes in this template to have
more consistency with the scope of 802.20 technology proposals.
The chair called for a straw poll about whether such a technology description template
should be developed.
Result - - 45 in favor.
Chair asked the contributor to work with the current TSP editor, Mark Klerer, to create a
proposed template that was consistent with scope of 802.20 technology proposals and
that was not overly long.
Break from 3:00-3:30pm.
Contribution by Dan Gal on “PHY/MAC Specifications – Proposed table to contents
requirements” C802.20-05-26r1
This a revised version of the contribution made in Session 14. There was debate about
whether we need such a table at all. The contributor responded that this table is only a
suggestion, and not mandated. The chair mentioned that the description template
proposed in contribution 35 may accomplish part of the function this contribution is
addressing. The chair suggested to the contributor that there was no consensus in the
group to put this contribution in the next version of the technology selection process
document.
Contribution by Dan Gal on “Compliance Table for the 802.20 Technology
Selection Process” C802.20-05-41
This consists of edits and additions to the existing compliance table. The chair suggested
that we look at this contribution in the future meeting or conference call. All agreed.

Closure Next Steps for the Documents:
The Chair also noted the expected new document versions are:
1. Channel Models – Final version will be permanent document PD-08
2. Evaluation Criteria - Version 17
3. Technology Selection Process – Version 1.0
New Business:
A motion was proposed “to give members the power to vote approvals even if it there is
no quorum at the Interim session.” The Chair stated given further inputs from EC
members and a review of the 802 P&P, he did not believe empowerment motions for
voting approvals without quorums were valid. Thus the proposed motion was not
entertained. The Chair will provide further opinions from other appropriate EC members.
Chair will also seek an opinion from the 802 Chair.
Motion was made by Jim Ragsdale and seconded by Joanne Wilson, to adopt Option 1
(deletion) in Section 9.1 Channel mix of the Evaluation Criteria document version 16r1.
Jim Ragsdale gave the explanation that a channel mix makes it difficult to interpret
results. The motion failed 17-21.
Old Business carried over from the Monday Opening Session
The chair presented the views of 802.22 and 802.15 about the creation of a wireless
architecture study group.
Straw poll on: Support an EC wireless architecture study group
Result: 33-7
Straw poll on: Support the approval of 802.1am PAR
Result: 1-38
Discussion was taken on Times for Conference Calls to accommodate members in
Japan/Asia. It was recommended that the call times rotate such that the same
members/regions were not inconvenienced all the time. The chair said he address rotating
times for the conference call when scheduled was set.
Motion to Adjourn
