Sorry, I did get a reply by Michael Green on 11/28/2011 but I never
followed up with the list. Apologies as well with the delay, but here
is our review.
The European Union has some harmonized European radio conformance spec
and QCA's interpretation and position is that that spec overrides
deviations for end products for specific countries like the one being
recommended for Norway. This also means that QCA does not deviate for
EU countries on specs, even if countries have their own quirks, for
any country in the EU.
Supporting changes like these are a deviation from what QCA is used to
using and testing and we unfortunately cannot verify any individual
country specific changes like the one proposed for the EU. It is also
our sentiment that we stand to gain more if we simply unify the EU
requirements through the harmonized spec, it provides simplicity, its
what we use and we can help in that regards. If wireless-regdb decides
to take a different path we simply will not be able to verify and
validate these changes. I'd be surprised if any other 802.11 vendor
differs from this position.
