18.5.TGax would like 2 more slots on Thurs AM1 and AM2.
18.6.WNG would like another slot.
18.7.C: Please note that AANI will have a short meeting, so this can be limited to an hour and therefore WNG can use the 2nd hour of that slot.
18.8.Chair: So, the AANI slot will be shared with WNG on Thurs AM2. The WNG will be for the student paper review that was not covered earlier in the week. It is not a joint meeting.
18.9.Chair: TGay can go into Wed PM1 and TGax into Thurs AM1 although this means that there will be 6 IEEE 802.11 meetings running in parallel for Wed PM1 and so I’d like to verify that the membership is content with this situation.
18.10.Straw Poll: Do you support having an additional session for TGay Weds PM1 (6 parallel)? (11-17-0875r6 slide #7)
18.10.1.Chair: From the show of hands, it’s clear that the membership is support of this.
18.11.Motion: Approve the room changes to the agenda 11-17-0847r2
18.11.1.Moved: Jim Petranovich, 2nd: Nikola Serafimovski
18.11.2.No objection to approving by unanimous consent
- Industry Update Activity
19.1.This will occur during the AANI meeting tomorrow.
- LC TIG Report (11-17-1048r2)
20.1.Q: regarding slide #11, how many light APs would be required to cover this meeting room that we’re in? Also, how do you prevent interference between APs in the same room?
20.2.A: probably about 40/50 for this room. Regarding the interference, this is a problem that needs to be solved within any future task group. Of course, if you switch off the lights in a room, the light communication will also stop.
20.3.Q: The major appeal of IEEE 802.11 is its appeal and the large volumes.
20.4.A: The goal of the study group would be to define a scope and produce a PAR.
20.5.C: Commercial viability should also be considered by the study group. It needs to consider why light communications is required in addition to 11ax or opposed to 11ax. It should address the incremental advantages of this new technology.
20.6.Q: Within one of your usage scenarios, downlink doesn’t really require CSMA/CA?
20.7.A: Yes, and this does need to be considered by a future task group. Slide #31 may hint at such a solution.
20.8.Q: Is there any concern about light sensitive people?
20.9.A: There are various safety standards for lighting which need to be met, especially for flickering.
20.10.Q: Regarding the figure on slide #31, how will the upper MAC be connected to the individual lights and lower MACs. It appears to be a new architecture.
20.11.A: This is just one solution that has been proposed. Handling rapid mobility between lights will be difficult and needs to be considered within a future group.
20.12.Q: This appears to be an asymmetric solution?
20.13.A: The study group will have to discuss this and decided whether an asymmetric or symmetric solution is the way forward.
20.14.Q: One slide #31, are there suitable radio regulations for the multiple radio approach?
20.15.A: I’m not sure.
20.16.C: Thanks for the work that the LC TIG has group. My concern is whether this should be a standalone standard or part of IEEE 802.11. The current standard is 4000 pages and is becoming unmanageable. I think for green field bands, we should consider new standards as opposed to amendments to IEEE 802.11.
20.17.A: Yes, this needs to be discussed within the study group.
20.18.C: I think this topic is very vague and I wonder if IEEE 802.11 is the correct venue to discuss this topic.
20.19.C: This is a very interesting technology and the LC TIG has done a good task covering the problem space. The study group will now consider whether this should be standardized. However, will be there be enough people with sufficient interest to move this forward.
20.20.A: Yes, I think there will be enough people to do this work.
20.21.Chair: What would you like to do next?
20.22.C: I would like to have a straw poll please
20.23.Straw Poll: Would you support the formation of a Study Group for LC to
20.24.evaluate and to develop a PAR proposal?
20.24.1.C: I am not in favour of this straw poll, as certain aspects are not very clear
20.24.2.C: I am in favour as a study group will further discuss the scope of work required.
20.24.3.C: I am not in favour as I don’t think IEEE 802.11 is the correct venue for this work.
20.24.4.Yes: 75, No: 31, Abstain: 49
- Awards (11-17-1024r0)
21.1.Chair: We will now present awards to everyone who provided considerable assistance within TGah. Photographs are now allowed.
