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 ---
ITS around the globe is most assuredly interested in anonymity and various
groups are working on the problem. There are no published standards yet,
however, that detail any particular protocol. It's not as simple as
changing the MAC address. ALL addresses at every layer that are in the
clear need to be tumbled at the same time! This is a significant
cross-layer synchronization challenge.

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.
