Subject: CHANNEL FREQ'S

Geqqam69200,

I've seen a few people refer to the lower 6 channels of wireless as
operating in the Ham freq. spectrum.  I am a bit confused where this is
coming from as 802.11b operates in the ISM (Industrial Scientific and
Medical) band.  This band (~2.4 GHz) is used by 802.11b to transmit using
spread spectrum signals so technically speaking all channels are sent in the
same frequency band.  I have always been under the impression that the
channels simply referred to the code necessary to retrieve the spread
spectrum signal sent. 

If I'm wrong in my assumptions I'd like to become more educated. To that end
I'd appreciate you (or anyone) posing the reference stipulating that the
lower channels are in the Ham frequency spectrum while the others are not.  

Thanks
