Although I don't claim to be a lawyer, I found this information from=20
http://www.softwarefreedom.org/resources/2007/fcc-sdr-whitepaper.html,=20
which is a translation of the FCC's rules regarding software defined=20
radios (including 802.11 chips).

Snippet 1:

The rules require any manufacturer certifying a device under the new=20
process to take steps to prevent =93unauthorized=94 changes to the soft=
ware=20
on the device that might alter its radio frequency and power parameters=
=20
in a way that takes it out of compliance with the regulations known as=20
=46CC Part 15 regulations.2 The specific technology implemented to=20
accomplish this task is left to the manufacturers seeking certification=
,=20
although the FCC suggests several possible mechanisms that can serve as=
=20
such =93security measures.=943

Snippet 2:

Since software is a representation of a mathematical algorithm, it is=20
not a =93device=94, =93home electronic equipment=94 or a =93home electr=
onic ...=20
system.=9417 Further, there is no precedent for applying the device=20
certification rules to software except as installed as a component of a=
=20
specific hardware device. Indeed, the FCC has explicitly limited the=20
certification requirements to =93hardware-based device[s].=9418 Both of=
=20
these facts make it clear that the FCC rules do not apply to software b=
y=20
itself, but only to hardware-based devices.


What I get out of this, and out of poking in the legal babble, is that=20
as long as our firmware doesn't cause the hardware itself to violate FC=
C=20
specs, we're in the clear. According to Snippet 1, it shouldn't even be=
=20
possible to violate the specifications, but we all know how good=20
manufacturers are at stuff like that ;P.
