14. JTC1/SC6 SC ISO/IEC JTC1/SC6
General update in Atlanta
Reviewed latest liaisons to SC6 of Sponsor Ballot drafts
802.11ac D2.0
802.11ad D6.0 & D7.0
Reviewed status of JTC1 ballot on IEEE
Opens 18 May, closes 5 month later
Decided to not send any supporting material to NBs at this time
Reviewed submitted IEEE 802 responses related to proposed agreement on extensions to IEEE 802 standards
Same (almost) material as that developed in May
Expect responses from SC6 NBs by 1 June for processing in San Diego meeting; our next round of replies due by 1 August
No news on WAPI; NP is still cancelled in ISO/IEC and still required by some regulations in China
WAPI NP could be un-cancelled in the future, but that would probably require a new NP ballot
No news on TLSec (802.1X replacement)
Being developed by BWIPS outside SC6
No news on TePA-AC (802.1AE replacements)
No news on LRWN security proposal
Project is not known to be progessing anywhere
Some news on UHT/EUHT (802.11n/ac replacements)
UHT and EUHT are now Chinese National standards
Previously feared that EUHT would cause 5GHz not to be opened up in China; it now appears 5GHz channels could be opened in 2012

15. Regulatory SC Regulatory Summaries Decoupling Regulatory Changes
North America
USA
Opening the 5350 – 5470 MHz and 5850 to 5925 MHz bands
NPRM to resolve TDWR issue still in process
June 19th TVWS FCC Part officially became law
Industry Canada is working on RSS-210  Rev 9 for 5 GHz band
European Union
First ETSI BRAN TVWS meeting was held June 6th – 8th to begin development of EN
Closely following OFCOM Voluntary National Standard
TG11 meeting was held June 4th and 5th on 2.4 GHz EN v1.9.1
RCWG sent LS to R&TTE CA and ADCO on the 5600 to 5650 band
If only illegal operators are interferers, do not close the band
Should we prepare similar letter to R&TTE CA and ADCO?
Asia - none
Decoupling Regulatory Changes
Regulatory input to base standard
Regulatory changes occur asynchronously with amendments and amendment roll-ups
This can affect the development of an amendment in process
Can be done like ANA
Adrian worked with Peter to a procedure for add regulatory updates in the ANA database
To be reflected in new IEEE OM
