Remember, it's in Extricom's interest to demonstrate a scarcity of channels (less channel choice = more co-channel interference) because they have a coordinated RF approach.
While the second-generation of 802.11n draft 2.0 chips from Atheros deals with some of DFS challenges, I was led to believe that it's still not 100% (that was from a vendor who doesn't have 802.11n gear today). Even if one has to momentarily ignore the 255 MHz in the middle, there's still 6 channels, more than enough to run a pilot where there's no 802.11a in production today. Attached is a channel map supplied to me by a vendor.
