Agreed. There is rarely a thing as a perfectly-directional antenna (not without a lot of shielding, I would presume). Since I would presume that all the radios are controlled by the same host, perhaps it could coordinate the 802.11 DCF and sequence CTS frames so that the various client and AP radios remain as spectrally orthogonal as possible. There's not much you can do about the clients transmitting RTSes, but it can be predicted to a certain extent. > there's no magic bullet you simply can't do it all in one ap with the > space available. Agreed. More, lower-power APs means better spectral efficiency and overall resilience. --j
