FYI - this configuration does not conform to the 802.11 specifications. Regards, Jon 303-808-2666

The loss that you get from overlapping is largely regained by having a 4th channel. Other sources advise to play with smaller cell and reducing the milliwatts emitted from the AP instead of using 4 channels! CIROND published a paper about the usage of 4 channels as well, (search for CIROND, 4 channels, 802.11b...) warning that though it is acceptable with CCK, it might create problems with OFDM!
