Most contentious issue is still 40MHz channelization
Bruce Kraemer

7. 802.11 TGp Wireless Access for the Vehicular Environment
LB125 fourth initial WG ballot on IEEE p D4.0 closed 5/3/ Results: 136/37/ % Passed

Clint Chaplin

9. TGs Mesh Networking
LB126 second initial WG ballot on IEEE s D2.0 closed 5/3/ Results: 103/67/ % Failed.
1958 comments; 2/3rds technical
Working on resolving comments from LB; hoping to go for a third initial WG ballot after September meeting
Security is still the most contentious issue; other issues just need to be addressed and worked through.
Donald Eastlake

10. 802.11 TGT Wireless Performance
LB101 initial WG ballot on IEEE D1.0 closed 5/16/2007 (one year ago). Results: 163/52/ % Passed
Unable to achieve critical mass of TG participants since then.
Voted in the TG this meeting to recommend to withdraw their PAR; results 4/0/1
Vote in WG to recommend to withdraw PAR was 66/0/6
Next step is to take recommendation to withdraw PAR to IEEE 802 Executive Committee
Nerraj Sharma

11. 802.11 TGu InterWorking with External Networks
TGu is resolving comments from second initial WG ballot which closed in March. Optimistically expecting to go out to third initial WG ballot after this meeting meeting
19 MIH related comments: 6 rejected, 5 accepted, 2 counter; 3 to discuss, 3 waiting for submission
Many comments on definitions, not many comments on functionality of MIH
Stephen McCann

12. 802.11 TGv Wireless Network Management
TGv is resolving comments from second initial WG ballot which closed in March. Expecting to go out to third initial WG ballot after this meeting.
Major work around the location services and their action frames; making more explicit the determination vs. reporting functions.
Dorothy Stanley

13. 802.11 TGw Protected Management Frames
LB128 recirculation WG ballot on IEEE w D6.0 closed 4/18/ Results: 266/8/ %
WG will vote at the Friday plenary on recommending to IEEE 802 Executive Committee that w D6.0 be forwarded to Sponsor Ballot
Next step will be 802 EC approval in July

Three presentations at this meeting
Segregated Data Services ( wng-segregated-data-services.ppt) Donald Eastlake (Motorola)
Re-presentation of earlier proposal
Scheme to allow different classes of network users different views of network resources, especially on mesh networks
VLAN like, but at MAC level
Facilitating Power Line Communication PHYs ( wng-facilitating-power-line-communication-phys.ppt) Clint Chaplin (Samsung)
Hybrid MAC with Powerline Communication PHY
Certain use cases that wireless can’t cover, and where cable can’t be installed

18. ARC Architecture SC
New Standing Committee meeting for the first time.
Dave Bagby is chair, Darwin Engwer is Vice-Chair
Intent is to try to rationalize the architecture of ; has had 11 amendments already added, and 14 more amendments in process
The base document is a topsy-turvy hodge-podge that organically grew; no overarching framework.
needs to be cleaned up.
David Bagby

19. VHT Study Group Very High Throughput
Working on two PARs for two new task groups
> 1Gb/s goodput goal for both
One PAR for frequencies < 6GHz
One PAR for frequencies at 60GHz
Motion in mid-week plenary to accept PAR for <6GHz: Results 32/19/24 Failed
Motion in mid-week plenary to accept PAR for 60GHz was deferred until Friday plenary
Many object that the PARs are too vague.

20. JTC1/SC6 Ad-Hoc ISO/IEC JTC1/SC6
China has reached out to IEEE to explore bringing WAPI to IEEE to incorporate into the standard
Ad-Hoc drafted a response letter to be sent back to China inviting them to attend July meeting to explore the idea. One recommendation is to do an initial presentation in WNG in July on WAPI.
A possible meeting in June in China could also be used to explore the possibility.
