The CFI/CFP Process
• The figure to the right depicts the current state of the TG3a CFP Process thinking.
• The WG requires a CFI to prepare the agenda.
• Typically a CFP runs 60-90 days and the CFI is 30 days BEFORE CFP deadline.

Proposed CFP Timeline• Nov02 Session #21/Kauai, HI USA
– We approved and then released the CFP on 3Dec02.• Jan03 Session #22/Ft Lauderdale, FL USA
– We are planning that the TG3a approve the docs from the SG3a.• Mar03 Session #23/Dallas, TX USA
– Proposals will be first heard in this Mar03 session.• May03 Session #24/Singapore, Singapore
– If too many proposal for the Mar03 session, this will be the overflow. – We should spend part of this session discussing proposals presented, answering technical
questions/concerns (i.e. put the diehard engineers in a room and let them verbally duke it out). – Spend time on conference calls discussing proposals to let everyone get comfortable (before and after
this session). • Jul03 Session #25/San Francisco, CA USA
– Down Selection and Voting will occur here– 1st opportunity for automatic quorum after Mar03 presentations
• Sep03 Session #26/TBA– Potential to start the drafting process - proposals for draft improvements should be entertained at this time
• Nov03 Session #27/Albuquerque, NM USA– TG3a drafting process

Scoring Discussion• Document scoring method in Annex for inclusion in IEEE
P802.15-02/105 Alternate PHY Selection Criteria – Contribution in 02/271r4, text to be reviewed in January
• Decisions – Extent of Scoring: tabulated information (13) vs. tabulated
information with committee analysis (35) vs. abstain (1)• Definition of committee analysis activity to be determine by end of
January meeting– Criteria to Score: only most important (A’s only) vs. all criteria (no
objections)– Definition of N > 2 Rating
• How many levels desired: 3 levels (26) vs. 5 levels (23) vs. abstain (4)• Levels labeling: + / 0 / - (24) vs. a worded version (21) vs. abstain (3)
