  1. Comments on the Technology Selection Procedures for 802.20 Joanne C. Wilson ArrayComm, Inc.

  2. Agenda • General observations • What does 802.20 need? • Attributes of a good TSP • A few more observations… • Proposal • Key elements of 802.11n TSP • Comments on current TSP proposal • Summary

  3. General Observations • We could spend many months defining and debating on the attributes a Technology Selection Process • There is no single, perfect process for selecting among technology proposals • Any process we adopt is likely to need refinement during its execution. • 802.20 must adopt an executable TSP before technology proposals can be accepted and considered. • At the same time, we need to adopt a TSP that will work effectively and facilitate future progress.

  4. What does 802.20 need? • A TSP that is good enough for the job at hand. • To leverage the experience of other 802 working groups. • To avoid reinventing the wheel • To get on with it!

  5. Attributes of a good TSP: • Clear and unambiguous set of procedures • Promotes compliance to requirements • Ensures uniformity in technical level and content of proposals • Promotes discussion and disclosure of necessary and sufficient technical information • Treats all proposals fairly and consistently • Funnels down to ultimate selection between the two best alternatives

  6. A few more observations… • Other 802 working groups have developed and executed TSPs before • No matter what TSP is adopted, 802 P&P mandates a 75% threshold for success … • …and therefore, a deadlock will always be possible. • Therefore, the TSP must promote consensus and cooperation

  7. Proposal • 802.20 WG should consider adopting adaptation of 802.11n process presented in C802.20-05/12.

  8. Key Elements of 802.11n TSP • Adopts requirements, evaluation criteria, channel and usage models prior to call for proposals • Allows for either complete or partial proposals and specifies handling of each • Specifies in detail the process steps and requirements on proposal submitters • Conducts down-selection in rounds, each of which eliminates the proposal with the least amount of support

  9. Key Elements of 802.11n TSP • Allows merger, resubmission and re-presentation of proposals prior to each down-selection round • Mergers may not occur among eliminated proposals solely • Confirmation roll call vote occurs when one proposal remains. 75% approval required for confirmation. • Confirmed proposal adopted as basis for initial specification of draft standard without further voting.

  10. Comments on Current TSP Proposal • “It does not (as of the current version) include all components of a complete procedure.” (C802.20-04-72r3) • Requires revision and consolidation to occur prior to down-selection. • Proposes to rank proposals, without a relationship between the “ranking” and “selection” processes. • Assumes that one proposal can achieve a 75% threshold in a single round of voting among N proposals

  11. Summary • 802.20 needs a TSP that is good enough for our purposes. • Other 802 Working Groups have developed, executed and further refined technology selection processes. • 802.20 should leverage the experience of other 802 working groups. • 802.20 WG should consider adopting adaptation of 802.11n process presented in C802.20-05/12.
