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 802.11-2012 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 Andrew Myles (not updated)

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 15.700 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 301 598 Closely following OFCOM Voluntary National Standard TG11 meeting was held June 4th and 5th on 2.4 GHz EN 300 328 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 802.11 OM Rich Kennedy
