Decision No. 4004-01DEC-CRA, 8th Edition - February 2019,
Radiocommunications and Regulatory Organization.
General radio license for the use of parts of the frequency bands
2400-2483.5 MHz, 5150-5250 MHz, 5350-5250 MHz, 5470-5725 MHz, and
5850-5725 MHz in radio access networks. [1]

* 2400 - 2483.5

  - 10dBm in every 1Mhz
* 5150 - 5250
  - 200 mW e.i.r.p
  - 10dBm/MHz per 1MHz bandwidth or -6dBm/25kHz per 25kHz bandwidth

* 5470 - 5725
  - 1000 mW e.i.r.p
  - 17dBm/MHz per 1MHz bandwidth
  - DFS
  - If TPC is not used, the maximum radiated e.i.r.p. must be reduced
    by 3dB.
  - Outdoor use only
    (Since NO-INDOOR flag is not supported by current format, don't add
     this entry.)

Should keep a note saying for outdoor only usage, the limit is 4000 mW.

For outdoor only usage, the limit is 1000 mW.

Also, for outdoor usage, TPC is required, and there is no provision
for 3 dB power reduction if TPC is not implemented.

So I would mark this band as indoor only for now.

There are NO-INDOOR and NO-OUTDOOR flags for the database. The kernel
doesn't have a matching IEEE80211_CHAN_OUTDOOR_ONLY flag though.
Maybe that should be added?

Johannes, what do you think?

This band is point to point only. TPC is required without provision for no TPC.

Good question. I guess we could have it, though I'm not sure we'd have
any mechanics to actually _use_ such a thing right now? Something, say
hostapd (?) would have to promise it's actually outdoors?

More information doesn't hurt and I don't mind adding it at all, but I
do think we'd probably not be able to use it at this time.

Or we could add it to the db.txt file but ignore it in parsing now and
skip the band for the binary for now?

The thing is I don't think we have a good way to say "older kernel skips
this range" - or perhaps we set the NO_IR flag so older kernel cannot
use it but then allow OUTDOOR_ONLY to override that given some
conditions?

Thanks for the patch, I should mention the document date is February 
2021, Not 2019.

Thanks for the suggestion. I have made a patch to allow NO-INDOOR flag, but
not parse into binary.

Since I'm very not familiar with Python, please review the patch carefully.
Thank you.
