placement of 3 cards on a PC box

[Mustafa C. Kuscu]

Dear all,

      I would like to have 3 802.11b cards on my hostap box. I don't
   know about the interference issues with the 802.11b PCMCIA cards
   with internal antennae, especially if the cards are placed very
   close to each other. For instance, consider the figure below where
   an empty slot separates each neighbor. Would the interference be
   so bad, because of the small separation between the cards (and their
   orientations with respect to each other), even if the cards operate on
   channels 1,6,11? What other physical configurations do you recommend?
	Thanks -- Mustafa
