the contributors in the room if that is agreeable to them.
There is a consensus and an agreement that we move forward on the agenda if items get
covered faster than the currently stated time schedule.
It was also agreed that we would maintain the order and sequence of the topics of
coverage as proposed in the agenda.

editorship for the Evaluation Criteria document.
Given there were no volunteers, the Chair stated he would be the acting editor of both
documents for the session. He would also act as the editor of the Evaluation Criteria
document until a suitable editor could be found.

edited, corrected and modified on all the items that were previously agreed.
For Section 3.5, it was agreed that Ayman Naguib will provide a rewrite for the whole
section.
In Section 5, Ayman Naguib was asked to address this section in his proposal consistent
with section 3.5.
For Section 5.6: It was decided to add an Appendix to explain of why Section 5.6 is
included in the document. It was also agreed to decide the ordering of section 5.6 based
on what the group decides on Section 3.5.

Resume: 10: 35 am
Presentation by Dan Gal on “IEEE 802.20 Evaluation Criteria (EC) - Simulation of
Common Traffic Types” (C802.20-05-25)
Discussion followed:
There was no consensus for the proposals made in this document.
Clarification was requested by the WG members on what exactly is Traffic Mix. Chair
requested that point be cleared in the new updated revision of the document.
The important question for the group is - - should Traffic Mix mean (1) “a mix of users
across the system for simulation purposes each using a specific single application” or
“each user in the system having a specified application mix”?
Lunch Break: 12:45 pm
Resume: 2:00 pm

Old Business carried over from the Monday Opening Session
1. The group reviewed a one slide presentation from David James and Jim Ragsdale
regarding improving the interaction between 802.20 and 802.18. The chair had
requested a write up in the Monday Opening. (Note: The Chair excused himself
for 10 minutes while slide was reviewed.) There was discussion upon the Chair’s
return. The Chair agreed to add the discussion points to the slide and sent to the
presenters and other interested parties that were present for review for accuracy.
Following that review, the chair will send the slide to the group reflector. The
presented slide is below:
9
IEEE 802.18 /.20 interaction
• experience at last mtg. and with recent 802.18 outputs reenforce need for discussion, clarification
• propose:
– 802.18 promptly inform .20 of all potentially .20-related material, planned outputs etc
– arrange short, joint .20 /.18 mtg. near the start of each 802 session
– need recognition of reciprocal .18/.20 participation credit where attendance needed
– .20 needs .18’s agenda for each session, would appreciate plan for the session
• .20
needs clarification of .18/.20 interaction rules
Jim Ragsdale, Dave James
2. The Chair reviewed the 802.1 AM proposed PAR and asked for inputs. This was
initially review in the Monday Opening and agreed that it would be discussed again
on Thursday. This discussion led to the New Business item on the Wireless
Architecture meeting. No conclusions on 802.1 PAR were reached by the group.
New Business
The Chair reviewed the below embedded Power Point slides below from the Wireless
Architecture meeting Tuesday evening. (Note: double click on the below objection to see
all the slides.)
Discussions at Architecture Meeting
• ~60 people present (40 signed attendance sheet)
• Discussion turned initially to the 802.1AM PAR
– There was concern that 802.1 may not have the expertise to do
the RF management task
– Question: Is management of an RF system fundamentally
different than a wired system? Yes.
– Straw poll: “Do you favor approval of the 802.1AM PAR?” yes
13; no 20; reserve judgment 13
• Discussion then turned to what wireless groups need in
common
– Straw poll: “Is a common language needed for wireless for
communicating operational characteristics and status of
dissimilar wireless systems?”
yes 23; no 1; reserve judgement15
10
A discussion followed and a few members made comments. There was a concern that it
was increasing difficult for an individual to cover all the WGs, TAGs and Study Groups
that “cross and serve all the wireless groups.” The Chair stated he would send the slides
to the group reflectors and seek further inputs by email.
