That depends somewhat on the hardware design. I've seen cards that can
receive IEEE 802.11b frames from other stations when the devices are on
channels 1 and 11.. Sure, they needed to be quite close to each other
and lots of frames were dropped, but some were still getting through. In
other words, even if the card does not jump around to different
channels, you can easily get a frame or two from far away channels every
now and then.
