Well, no... we need the concept of "the public's" spectrum, also.

The best approach that we can think of to ensuring regulatory
compliance throughout the globe, in linux, has long been:


and making it all available as open source code, as we do.

The only way it could be improved would be for devices to also try to
determine where they actually are on boot, and to mandate that all
device makers seeking FCC compliance publish their source code that
shows it making the appopropriate calls into that database - and the
FCC mandate regular updates, and so on.

I of course would go a step further and mandate all wifi drivers and
firmware be made available as open source code in publicly available
git repositories - wifi has FAR more problems than just potentially
emitting on the wrong bands or at the wrong power, and I would hope
the FCC wold recognize that making wifi better, for everyone, should
also be a goal, rather than just protecting their radards.

I keep seeing things on how LTE-U is "1.6 times better than wifi" -
which does not use a definition of "better" I agree with...

... and we've already outlined how we intend to improve wifi's
behavior by much more than that - by reducing power, improving spacial
reuse, and improving aggregation, and so on.

I am trying - and failing - to write a letter today on that.

Well, pushing the responsibility back on the actual users of the
technology is fine by me. Enforcement seems only to be of a concern on
the DFS channels around a limited number of airports.
