IP policy
A SC is covered by the WG IP policy announcements.
Even though we don’t have to read the policy to SC attendees, all attendees are reminded that the policies are in effect and apply to SC sessions.

8. The 802.11 Arc Standing Committee: Mission
July 2008
The Arc Standing Committee: Mission
Established by the new WG Chair as a Standing Committee in May 2008
Mission: The Arc group is tasked to discover, analyze, codify, and promote a common understanding of architecture.
Discover: To notice or learn, especially by making an effort; Archaic To reveal or expose;
Analyze: To separate (a material or abstract entity) into constituent parts or elements; determine the elements or essential features of;
Codify: To arrange or systematize;
Promote: To help or encourage to exist or flourish;
The Arc team utilizes members with significant expertise, experience, and history within

9. Arc: Initial Activities (May 2008)
July 2008
Arc: Initial Activities (May 2008)
1) What is the Architecture as of ?
Stick strictly to “what it is”, not “what do we wish it was”.
2) What will the Arc impacts of current TG activities?
3) Work with SGs; which portions of Architecture they are modifying?
4) Contact point for architecture liaison topics.

10. Arc: Initial Activities (Feedback from May 2008)
July 2008
Arc: Initial Activities (Feedback from May 2008)
Attendees expressed desire to for the project mix to be
multiple, smaller, shorter duration tasks.
Include more “forward looking” activity
A suggested forward looking example:
VHT ”MAC split / reuse”

11. July: A smaller topic, for a mixed look at history and future needs
Instead of starting on project 1 (analysis of existing architecture) from May, we are going to take a single, limited architectural “chunk” topic and explore
What is it in the 2007 std?
(May Project 1 aspect)
How will current activities impact it?
(May Project 2 aspect)
SG/future future needs?
(May project 3 aspect + extapolations)
Driven by a specific example question

13. Discussion Topic Ground Rules
July 2008
Discussion Topic Ground Rules
We are exploring -
Small group, open, honest dialog
There is no “right” or wrong”, we’re seeking shared understanding, (any debating points “scored” are not redeemable…)
Session is not oriented toward being a tutorial, discussion presumes familiarity with 2007 contents.
David Bagby, Calypso Ventures, Inc.

14. July Topic: Mac block diagrams
Specific discussion questions:
What’s inside the block?
What’s “upper” and “lower”?
Existing from 2007 std
Current activity impacts (not in 2007)
Exploratory future looking discussion
