Re: [STDS-802-11] Updated version of RFC4441bis is available; plan to discuss in ARC on Weds
--- This message came from the IEEE 802.11 Working Group Reflector ---
Rene,
I'm not aware of a "report" on the consideration of temporary/ephemeral
MAC addresses in 802.11i, but this was one of the proposals:
https://mentor.ieee.org/802.11/dcn/02/11-02-0109-01-000i-temporary-mac-address-for-anonymity.ppt
Also, I believe ITS is using temporary MAC addresses. I don't know
where that usage is documented, but I assume it's somewhere in the 1609
standards.

If you wish to be removed from this reflector, do not send your request to this reflector - it will have no effect.
Instead, go to http://listserv.ieee.org/cgi-bin/wa?SUBED1=STDS-802-11 and then press the LEAVE button.
If there is no LEAVE button here, try http://listserv.ieee.org/cgi-bin/wa?SUBED1=STDS-802-11-RO.
