1:30 PM – 3:30PM

  1. Chair calls meeting to order at 3:07 PM

  5. Technical Presentation – Proposal and NormativeText for a ScheduledAutonomous Probe Response Generation Function – Steve Emeott - 11-04/1010r0
  6. Question – Why can’t I send a beacon or more beacons? Answer – Probe responses don’t have constraints of having to be sent at a certain time.
  7. Question – are there benefits other than “frequency of occurrence” over normal Beacons?
  8. Comment – We are proactively taking measurements in advance to find out where our best next AP is located.
  9. Comment – Legacy clients can probably use Beacons, but 802.11e clients may require.
  10. Comment – Requiring STAs to send beacons ever 10ms for every virtual AP would cause a great deal of traffic.
  11. Comment – the Neighbor Table should be able to provide all the information we need. You should know exactly when the Beacon is coming.
  12. Meeting in recess until 8:00 AM tomorrow morning.

Motion

Move to accept the agenda

Moved by Amjad

Seconded by Black

Motion passes unopposed

  1. Technical Presentation – Radar Avoidance 5GHz – Amjad - 11-04/1007r0 (PPT)
  2. Question – Why are you adding map information? If there is radar then it would not be in the neighbor report. Answer – I left the map information to simplify the protocol.
  3. Comment – If the radar-bit is set then you should not be on the channel. Regulators will not allow this. They only trust the AP on the channel at that time.
  4. Question – Have you ask the regulators? Answer – no. I must have a presentation prior to presenting.
  5. Comment – 802.11j has a method for this, so you probably don’t need.
  6. Comment – stations don’t have the same regulator restrictions as an AP.
  7. Comment – Radar avoidance is not completely addressed in 802.11h.
  8. Technical Presentation – Neighbor AP Selection Criteria– Emeott - 11-04/1004r0
  9. Address comment #800
  10. Comment – the “unknown” case is the same as reachable.
  11. Question – why would a client ever want information for APs that do not match its characteristics?
  12. Comment – the neighbor report should streamline the client’s process, so only querying the APs that match you might get a response from an AP behind a column.
  13. Comment – the power of the neighbor report is that it is fully broadcast to all.
  14. Comment – it may not be appropriate to broadcast the neighbor report as often in a densely populated wireless configuration.
  15. Comment – We should make the neighbor report available on association. It is likely the neighbor report will be used for roaming.
  16. Comment – you could have legacy APs and 11k capable APs in your area. The legacy AP might be your best roaming candidate, so you would want to know about APs that don’t currently match the station.
  17. Comment – we should quantify the usefulness of this proposal. What is the likelihood of stations making these requests?
  18. Comment – Clients can operate in multiple modes (a, b, and g) so it might need to know the capability of APs that do not match its current state.
  19. Comment – the country code is not mandated to be broadcast in every beacon. This would reduce the demands of broadcasting the entire information element for every beacon.
  20. Vote on teleconference Minutes

Motion

Move to accept minutes Portland-Berlin in document 11-04-01024r0.

Moved: Kwak

Seconded: Klein
