  From what I've read, not quite: It's CSMA (Carrier Sense Multiple
Access) without the CD (Collision Detect).  Most 802.11 stuff can't
detect collisions, because a radio which is transmitting can't tell if
another radio is also transmitting on the same frequency at the same
time.  Like with walkie-talkies; when you're transmitting, the
receiver is disabled.  So collisions hurt even more because the
equipment can't even tell there's been one.

  I dunno about the stuff which uses multiple transceivers.
