This has come up in the past. The problem is that NICs aren't tested for those frequency bands. You'd have to do your own local certification just to ensure that the NIC is working correctly and not spewing crap everywhere. Just because the RF synth may go down to 2.3GHz, doesn't mean that it will do so without spurs, distortion; doesn't mean that the chosen LNAs/FEMs aren't going go distort at that point; that they don't draw higher current when operating out of the normal bands, leading to distortion; etc, etc. I'd like to write/release a bunch of testing tools to let the open community do this themselves, but the worry is that the FCC will get angry.
