8:15SG chair called the meeting to order
SG chair announced a change in today’s agenda. At 10:30 AM instead of Chan Rypinski’s submission we will respond to a comments to the HR PAR from 802.11. Rypinski’s submission will be moved to Thursday.
8:18Presentation by Dave Leeper, Intel, representing Bluetooth’s requirements for HR
Question: Why doesn’t the BT SIG just do a HR device on its own rather than wait for 802? Question: What is the frequency range suggested by BT? Reply: (DL) don’t know yet. Question: Do you think that 802.11 will question that this project is not distinct from the 802.11a or b? Reply: ( DL) The intent of 802.11 is to be a LAN, while the PANs are meant to quickly connect and then disconnect, i.e. temporary attachments. Question: When you say 10 Mb/s for streaming what streaming are you referring to? Reply: (DL) video. Question: Are there plans to support piconets larger than 7 devices? Reply: (DL) I think yes, but some would say no. Question: How fast could the SIG turn onto HR? Reply: (DL) 18 months?
8:40Rick Alfvin, Kodak, submission (IEEE802.15-00/075r0)
Significant discussions on security, what layer institutes it, how secure, etc.
9:15Rick Roberts, Intersil, submissions (IEEE802.15-00/049r0, /050r0, /051r0)
Comment: ( Chris Hegard) multipath model is flawed due to sampling time only has upper limit but needs lower limit. Error rate for MPEG3 needs to be less than 10-9. Question: what about losses through walls etc? Reply: Walls aren’t part of the POS. Question: won’t dual front ends will increase cost? Reply: Yes it will. Question: Isn’t non-coherent more robust even though it requires a higher SNR? Reply: Yes it could be true, I need to follow up on that thought. Comment: trying to get multiple users using spread spectrum would require more than 80 MHz.
10:35SG chair lead a discussion concerning 802.11’s comments to HR PAR (IEEE802.15-99/165r4).
The SG chair reviewed the written comments from 802.11 (IEEE802.15-00/084r0). The WG chair stated that responses to the 802.11 could be done at the joint session on Wednesday. The procedure was to define what areas of the PAR were appropriate to change and then set up a focus team to define the wording of the PAR.
Issue of range. Modify references to range to cite a range up to 10 meters. There were no objections to this change.
Issue of POS. Suggestion to delete the reference in section 13b to a person’s presence or non-presence and strike the reference to the house (strike the second sentence). There were no objections to this change.
Issue of embellishing the rationale for control over POS. Strike this (4th sentence). Vote was 14 for striking the sentence and 7 to keep it.
Issue of data rate exceeding 20 Mb/s. No PAR change. Rebuttal position would be that this PAR does not restrict operation to 5GHz. Another rebuttal position would be that 802.11a is not a low cost radio solution.
Issue of QoS. No PAR change. Rebuttal position is that on this point there is a similarity to 802.11e.
Issue of addressing all applications before submitting the PAR. No change to PAR, process is underway but not complete. Rebuttal position is to show the committee’s past efforts capture applications.
Issue of the free reign of applicability of the PAR. No change to PAR.
Session will reconvene at 5:30PM to define the final wording.
11:53Session adjourned
5:34SG chair called the evening session to order
WG chair reviewed changes as suggested by a task group consisting of Jim Allen, Bob Heile, Bruce Kraemer, Rick Alfvin, James Gilb, Bob Morris, Bill Bailey, and Pat Kinney (IEEE802.15-99/165r5x). Remove references in section 9 to WAP, 802.11 family, and HiperLAN.
Straw poll, to indicate general appeal to the attendees, was taken, it passed 27/0/1.
6:06Session adjourned

9:07Walt Davis, Motorola, presented an application on wireless multimedia (IEEE802.15-00/086r0)
Questions concerning whether the 7 channel requirement was independent of the 20 Mb/s.
9:34SG chair reviewed the next steps for the day.
Questions: long term process/schedule for this standard? Reply: we have a matrix of proposers, and Thursday we’ll have some time to discuss this issue further.
9:45Meeting adjourned
Thursday, March 09, 2000
8:15SG chair called the meeting to order.
Reviewed today’s agenda, and objectives. Marketing committee is relinquishing their slot for 10:30 – 12:00, which allows this group more time to discuss future activities.
8:22Chan Rypinski presented his submission on case for DOQPSK and requirements for high rate MAC (IEEE802.15-00/078r1)
(This paper is a summary of two submissions 00/077 and 00/079) Question: Why 5GHz? Reply: Small antenna, antenna directivity. Question: What were your applications? Reply: Military: hands-free for Ubiquity Communication.
9:47SG chair reviewed the proposal matrix (IEEE802.15-00/0034)
9:52Adjourn for break
10:35SG chair called the meeting to order.
Discussion on future officer slate for 802.15.3. John Barr will be the group’s chair, J Allen will be vice-chair.
SG Chair lead a discussion on the meeting process.
Issues:
- Need to use the meetings for interaction and sharing
- There is not enough time to review criteria after the presentations
- Need more time to update doc’s
Proposal
- Use the meetings for presentations
- Make all requests for criteria (requirements) a document page in the CFA/CFP
- Use a format like the one being used for comment resolution in TG1
- Use telecom calls to review #3
- Bring final changes to meetings for 802.15.3 session vote
- Move on to next presentations
10:45Motion to adjourn moved by Rick Alfvin, seconded by Kevin Marquess, following no objections, meeting was adjourned
