Optimistically expecting to go out to recirculation WG ballot after July meeting; more pessimistic expectation would be after September meeting Lee Armstrong

802.11 TGr Fast Roaming IEEE Standards Board Review Committee (RevCom) recommended to the full Standards Board that IEEE 802.11r be published IEEE Standards Board has accepted the RevCom recommendation. Clint Chaplin

802.11 TGs Mesh Networking LB126 second initial WG ballot on IEEE 802.11s D2.0 closed 5/3/2008. Results: 103/67/36 60.59% 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

802.11 TGT Wireless Performance LB101 initial WG ballot on IEEE 802.11.2 D1.0 closed 5/16/2007 (one year ago). Results: 163/52/57 75.82% 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

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

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

802.11 TGw Protected Management Frames LB128 recirculation WG ballot on IEEE 802.11w D6.0 closed 4/18/2008. Results: 266/8/54 97.08% WG will vote at the Friday plenary on recommending to IEEE 802 Executive Committee that 802.11w D6.0 be forwarded to Sponsor Ballot Next step will be 802 EC approval in July Jesse Walker

802.11 WNG Wireless Next Generations SC Three presentations at this meeting Segregated Data Services (11-08-0114-02-0wng-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 (11-08-0613-01-0wng-facilitating-power-line-communication-phys.ppt) Clint Chaplin (Samsung) Hybrid 802.11 MAC with Powerline Communication PHY Certain use cases that wireless can’t cover, and where cable can’t be installed Presence Information in Large Mesh Networks (11-08-0561-01-000s-presence-information-in-large-mesh-networks.ppt) Polychronis Ypodimatopoulo (MIT) More efficient method to discover network topology and network nodes in mesh networks TK Tan

802.11 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 802.11; 802.11 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. 802.11 needs to be cleaned up. David Bagby

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. Eldad Perahia

JTC1/SC6 Ad-Hoc ISO/IEC JTC1/SC6 China has reached out to IEEE to explore bringing WAPI to IEEE 802.11 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. Jesse Walker
