2 Agenda for SF meeting
A very preliminary agenda was posted – document #460 rev 0. Phil also started allocating time for people who want to propose and he will fill those into the agenda as those requests come in. Keep in mind – this is a second round so we are expecting more details of the proposals presented in May - please do not simply repeat what was presented in May. This is the time to go much deeper into the details of the proposal. Monday there will be an opportunity to attend 4e sessions – low energy is on Monday but channel hopping is on another day. The agenda will be revised and posted as more information becomes available.
Question was asked on what day the proposals will be – the answer depends on how many proposals there will be (merged or not) and how much time people need. So right now we do not know yet.
3 Progress and next steps - TG4e liaison, merging proposals.
Greg gives updates on the low-energy work in 4e. Wei- Hung’s updated document including low energy scan will be ready in SF. There was a proposal to add a new frame type for frame wake-up scans so that receivers can turn on or tx when they receive the wake-up frame. A working draft doc # 0427 rev 2 (14-May) is available on the progress. Next steps proposed by Greg: identify the things that need resolution, identify performance criteria and then think about how we are going to fold in the criteria into proposals.
There is a channel diversity effort in 4e – Kuor Hsin. The question is whether 4e needs to harmonize with the fast frequency hopping – so most likely only the slow frequency hopping is in 4e’s domain. Discussion of fast/slow frequency hopping and whether frame-by-frame basis hopping is at the MAC and faster frequency hopping may need to be at the PHY.
There is some confusion on these terms because fast hopping sometimes refers to spreading a bit onto different channels vs hopping every 2 bytes
Phil: Any feedback from merging?
Clint gave brief feedback on the FSK merges. It is proposedthat we schedule some ad-hoc time for merging on Sunday afternoon e.g. 1 or 2pm for merging the FSK proposals. The exact time will be posted to the reflector.
Kuor Hsin – we have a DSSS conference call to talk about merging. There are also some other activities that are going on. So far there have been no break-through progress, but we are working on it.
Rishi – there has also been some effort on the OFDM side to come out with common options, but it is still in progress.
4 Any other business
Some discussion of 802.11 and how they specify tables so that the channel maps are flexible – look at k and j and regulatory class 12. That has power limits and emission standards and different rules for the different techniques. The trick is to do the hop-sequences in an algorithmic way rather than have people manually enter the different rules. That makes mistakes less likely
Peter will present at San Francisco. Phil and Pat will coordinate.
Call is closed at 8:46 am.
