The relevant limit in Canada and the USA appears to be 1 W.

A laptop marketed in Canada or the USA might be illegal for
use in Europe, even if Debian is replaced with LiMux?

Power density should be more pertinent to interference than
total radiated power. Location should also be pertinent.
In an urban location, the neighbour can be a few m away whereas
in a rural location the neighbour can be half a km away.
But reference to density and location might introduce unaccepable
complexity.
Thanks for the replies, ... Peter E.
