Subject: [PATCH v2] wireless-regdb: update regulatory rules for Russia (RU) on 5GHz

Russian entry is incorrect. According to the last regulations document of Feb 29, 2016,
160 MHz channels and 802.11ad are allowed.

http://rfs-rf.ru/upload/medialibrary/c1a/prilozhenie-1-k-resheniyu-gkrch-_-16_36_03.pdf

Note that there was never a DFS requirement in Russia, but always was
NO-OUTDOOR on 5GHz.
Maximum power is 200mW that is ~23dBm on all 5GHz channels.
Also Russia has never been regulated by ETSI.

It is not very clearly stated, but I agree that it looks like TPC.
Where is it stated that we need 20 dBm on these ranges if they require
TPC?
Unfortunately I don't have devices with OEM software certified in
Russia to see what is the limit.

It's not specifically 20 dBm, it's halving the power limit (i.e.
reducing it by 3 dBm).

Based on the translation I've read of the document you've linked to as
well as a couple of others, it sounds like the use of these ranges
requires TPC. Since TPC is not supported in Linux, we need to reduce the
max EIRP for these ranges to 20 dBm.

While modifying them, let's also update the 5170-5350 range to 5150-5350
to match the regulations.

Thanks,
Seth

I suggest to leave it on 23dBm. It is low enough especially for 5650 - 5850.
I am sure that a lot of Linux devices are certified that have this limit.

The TPC mentioned in the reg doc doesn't explain what it means.
