Re: [STDS-802-11-TGM] Scope of RCM TIG
--- This message came from the IEEE 802.11 Task Group M Technical Reflector ---
Dear all,
We discussed this extensively in the meetings yesterday, and as far as I
was aware we were able to reach a common understanding at that time
around the purpose, reflected here by both Mark and Jerome.
That said, many participants in the RCM TIG may not be regularly
following TGM reflector or expect discussions on RCM TIG to appear
there. If there is now an assertion that we no longer have a common
understanding of the scope of RCM TIG, perhaps it is better that we
allocate 10 minutes to discussing in which sense our shared
understanding from yesterday is being violated in the beginning of next
meeting?
Thank you for your kind attention,
best regards,
Amelia
