IEEE 802.11 g/b wireless nodes communicate with each other using Radio
Frwquency
signals in the ISM (Industrial, Scentific, Medical), (you can see
why Hospitals want you
to shutoff Cell Phone's), Band between 2.4 Gig. Neighboring
channels are 54 Mhz apart.
However, due to the Spread-Spectrum effect of the singles, a Node
sending signals using
a particular channel, will utilize Frequency Spectrum of 12.5 Mhz above
and below the
Center Frequency. As a result, two separate wireless networks
using neignboring, (for
example, Channel 1 and Channel 2) in the same general vicinity will
interface with each
other. Applying two Channels that allow the Maximum Channel
Separation (MCS), will
Decrease the amount of Channel cross-talk and provide a noticeable
performance increa-
sing over Networks with Minimal Channel Channel Separation.
