RE: [802.21] 802.11 Requirements Teleconference for 5th Jan - CANCELLED
Vivek,
Please find enclosed some comments. I am posting here some of the
comments I discussed with you offline.

[Stefano] ok, but then why do we even need requirements? I am sure I can
find solutions that show that all the requirements are not needed, if I
look for it. To me, it is essential that the requirement document is
correct and consistent. Therefore, amendments are absolutely needed.
I've spotted another minor issue, more editorial. Req. 1.7 uses the term
"pre-authentication" meaning "before authentication". Please be aware
this term is ambiguous. In 802.11 pre-authentication is something very
different, since the term is already in use. Therefore, to avoid
ambiguity when the requirements are read by the 802.11 community, I
would suggest changing the term to something like "before
authentication".
My apologies for not catching these issues before.
Stefano
