Hm, 802.11-2007 5.4.4 "Spectrum management services" explicitly
mentions that both services TPC and DFS are required in some
regulatory domains for operation in the 5 GHz band.

well, that's a pity. We do have seperated HT feature sets for each
band but they are not seperated by operation mode...
[ Just for fun: Do you know how the AR5418 handled radars in
the proprietary turbo mode in the 5 GHz band? And how does
Atheros own driver/stack/etc. deals with this limitation?
After all Unex sold/sells the DNBA-81 on their product page
as: <http://www.unex.com.tw/product/dnba-81>
"DNBA-81 is a 802.11n 2x3 2-stream a/b/g dual band wifi
Cardbus designed specifically for laptops and *access points*/
home gateways/consumer electronics/multimedia entertainment
devices/peripherals with standard Cardbus slot." ]
