Hw has 2 frontends, a 2GHz with range 2312 to 2732MHz and a 5GHz with
range 4920 to 6100MHz, you can tune to these frequencies through sw
but not all cards can handle frequencies out of standard 802.11 range
(depends on preamplifier). There are also cards from ubnt with
pre-build hw frequency converters for 900MHz and 700MHz i think. If
you want anything else you have to do the hw changes yourself...
