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
