Um... not so sure about that.. My understanding is that you want different channels so the wifi signals don't step all over each other, not because they cancel each other out (a feat which is very hard to do in practice). The magnitudes of mag fields are additive; they only 'cancel out' when they're of the exact same frequency and are exactly in-phase, which you won't find in the wild. In addition, antenna theory is based on the vector addition of magnetic fields. I know a guy in the physics lab with a spectrum analyzer, I should have him do some readings... _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
