There USED to be three non overlapping channels. Now channel 6 overlaps
with every third house in many markets :-).

Standard Wifi has 3 channels that do not overlap. X4 cloaking has 6
channels that do not overlap and X4 cloaking has 11 channels that do
not overlap.
We use 4 WLM-54G radios in a WAR4 and have seen no great issues unless
two active radios are on the same channel. I am not sure about 6 but
I know for sure that 4 works fine. Incidentally the SR9 has almost NO
leakage. Even with the cards side by side they will not link up. In
order to get anything from them you need a pigtail and an antenna.

I'd recommend against that idea Matt. ALL devices leak some energy. And

amazing. If you can keep things 3 feet apart there is much less energy,
small small fractions in fact.
Alvarion with their FHSS gear can get away with such things because they
can
always stay enough hopping channels away from near by radios. FHSS has
72
(or is it only 70?) channels to choose from. WiFi has basically 2 these
days.
Where this one gets hard to explain is that people build such critters,
test
them in the lap and then say that they work. Life will change
dramatically
however, once installed into a working system AND with the addition of
real
customers with real traffic.
