Resolving comments
TGs ran an experiment that let the IEEE professional editor edit the draft during the sponsor ballot process, rather than after approval. Draft 7.02 is the result of that editing. TGs doesn’t consider the experiment a success; the IEEE editor had the draft too long before giving it back.

Joint Meeting with 802.1AVB

Having an BSS act like first class 802.1Q bridges (so they can participate in the dynamic reconfiguration and management protocols)
QoS Maintenance Reports
Making sure APs and STAs know the difference between "multicast" and "group address" as conditions for routing action ... so that a stream that has a DA with the "I/G" bit set does NOT necessarily result in a broadcast transmission (with all the attendant wastage of bandwidth).

November 2010
The group divided its work into two tracks for this week: Draft Cleanup and Regulatory
The Draft Cleanup group was reviewing and addressing two problems with draft d There are some comments with multiple, conflicting resolutions, which are being decided on, and there are some resolutions added into this preliminary draft that were not yet approved that are now being voted on or removed.
The regulatory track is reviewing the impact of the new FCC rules for the TVWS which were published on September 23rd and composing a petition to ask for changes. In addition, an Ofcom consultation on TVWS Geo-location Implementation was published on Tuesday which we are also now addressing. We are also restructuring the draft to move all regulatory domain driven elements to Annexes D and E.

17. JTC1/SC6 Ad-Hoc ISO/IEC JTC1/SC6
September 2010
Did not meet
November 2010
Developing two liaison statements to ISO/IEC JTC1/SC6
Refuting assertion that is insecure
Pointing out that WAPI has chosen protocol values that conflict with IEEE assigned values, and urging relevant WAPI proponents to apply to for numbers that do not conflict.
Andrew Myles

18. Regulatory Ad-Hoc September 2010 November 2010
Discussed regulatory summaries from North America and the EU
The impending FCC TVWS rulings, the FCC 5 GHz rules changes update
ERM TG11 - EN revision update status
Essential test suites being written
Next meeting is in October (conflicting with the Wi-Fi Alliance meeting)
ETSI BRAN to begin revision of EN
Issues considered critical at this time
Should IEEE involve itself in Wi-Fi Direct issue?
Could lead to FCC redefinition of Software Defined Radio regulations
November 2010
We discussed the updates from North America and the EU, and focused on reviewing the new FCC rules for TVWS devices in FCC and the Ofcom consultation received on Tuesday. The US updates focused on the new interim rules for devices operating in the 5 GHz DFS bands and the recent knowledge database publication clarifying the rules on software upgrade of previously certified devices.
