This should read:
+ RANGE_PWR(2412, 2472, 20, 0, 0),
The power limit is supposed to be +20dBm in the EU, and it's EIRP so
that includes antenna gain which I've set to 0dB.
For an authoritative document you need http://www.etsi.org but their
site is down just now, so I can't find the document I want.
