Hi all, I dropped off watching this for a while....

Seems like the update to IR2030 (GB country code regulations) was re-publ=
ished last year, and the
relevant sections are in pages 32 + 34-36

My reading of this is:

- Other stuff we changed 2 years ago seems ok, caveat I'm unclear when we=
 need to state half power
vs using mean EIRP?
- The 5.9-6.4Ghz range is now good for use (page 35 near the bottom), per=
haps add something like:

+=C2=A0=C2=A0=C2=A0 (5925 - 6425 @ 160), (250 mW), NO-OUTDOOR, AUTO-BW, w=
mmrule=3DETSI

- The 60Ghz range seems to available now, but I'm not sure what power num=
ber we should have in our
db.txt, see page 32.
Says "40 dBm e.i.r.p / 27 dBm maximum transmit output power"
- There are also some geographic restrictions, not sure what we can do ab=
out those?

So something like this perhaps?:

> +	(5700 - 71000 @ 160), (40)

Happy to knock this up into a patch if you can help with a little guidanc=
e (although it might be
faster for you to just commit the 2 extra lines if you agree?)

Thanks
