Perhaps I don't understand.. Generally in wireless we look at two things; bits to hertz and noise components. If the noise is LESS and the carrier is the same power spectral density, you will have a greater c/n. I've always wondered why wifi didn't implement an array of modcods which can be used with a given system. That way, when you attenuate you have lower efficiency modulation and coding which will allow you to deal with fades better. Maybe they do us it and I'm just not hip to 802.11?

You have that backwards, actually, but the legacy support in 802.11g for 802.11b clients does represent a performance hit even in the absence of b-only clients, so claiming that a and g are equivalent is only true on paper. -r (802.11a user before 802.11g, still love the relatively unoccupied 5 ghz spectrum)
