I believe Ruckus is working on something called ChannelFly that will utilize more than the standard 1, 6, and 11 2.4Ghz channels.

It comes down to the skirts again. Most low-end tools to measure wireless coverage do a poor job of showing this, but my understanding is that wifi RF is such that the skirts "flare out" quickly, and you have nearly all of the signal overlap even at fairly low power levels. These wide skirts makes it impractical to try for four channels... you're almost as bad off as if you tried to use all eleven. Joel, You forgot the "black magic" part of wireless ;-) We didn't go with theory back in 2000, but with measurements. In a large auditorium with 100+ users and 4 APs, we were getting better throughput with 1-4-8-11 than with 1-6-11-1. We didn't play with smaller cells.
