Hi Seth,
This is v3 of my TW/US 5GHz updates series. Sorry for the long delay.
Changes since v2:
- Moved the US U-NII-1 (5150 ~ 5250 MHz) patch in front of the TW patch
- Drop U-NII-1 power limit from 24 dBm to 23 dBm, to be on the safe
side of 250mW
Patch 1 updates the 5470 ~ 5725 MHz rules for Taiwan, specifically
the opening up of 5600 ~ 5650 MHz spectrum previously allocated to
weather radars. The transmission power limit is also corrected to
match the regulations.
Patch 2 changes the boundary frequencies for each rule for Taiwan to
match the frequency allocation table. The "regulation" database shouldn't
care about artificial channel boundaries.
Patch 3 updates the transmission power limits for 5150 ~ 5250 MHz for
the US.
Patch 4 adds the previously unusable 5150 ~ 5250 MHz band for Taiwan.
Patch 5 updates the transmission power limits for Taiwan, per the NCC's
official reply. This patch may be slightly controversial, as there is
no official English document. Either someone will have to independently
verify this, or translate the Chinese document.
Regards
ChenYu

Taiwan's Ministry of Transportation and Communications revised its
frequency allocation rules [1] on 2014/11/17, opening up 5150 ~ 5250
MHz to U-NII applications.
Taiwan's regulatory body, NCC, officially stated [3][4] that until
the technical regulatory standard [2] are updated to cover this part
of the spectrum, FCC rules (part 15E, 15.407, effective 2014/06/02)
shall serve in its place.
Also add AUTO-BW to this and the next (5250 ~ 5350 MHz) rule, so the
system can actually use VHT160 channels spanning these two rules.

2.5.3
Following the amendment of FCC part 15E and U-NII regulations effective
2014/06/02, and the opening up of 5150 ~ 5250 MHz and 5600 ~ 5650 MHz
spectrum in Taiwan, vendors have asked whether Taiwan's regulations
would be updated to match the new FCC rules, when this would happen,
and what to do in the interim.
The NCC, Taiwan's regulatory body has officially replied that new
amendments are under way, and the goal is to match the FCC rules.
Until the amendments come through, vendors are free to test and
submit applications using the new FCC rules for transmission power
limits and DFS requirements, though unintended / unwanted emissions
must still conform to the current standard, LP0002. [1][2]
This has been confirmed via a phone call to the NCC.

2.5.3
The FCC increased the maximum conducted transmission power for the
U-NII-1 (5150 ~ 5250 MHz) band to 30 dBm or 1 W for master devices
and 24 dBm or 250 mW for mobile/portable
devices.
Since 250 mW is slightly lower than 24 dBm, set the power limit to
a conservative value of 23 dBm.
Effective 6/2/2014.
See FCC KDB 905462 D06.

2.5.3
Taiwan's Ministry of Transportation and Communications revised its
frequency allocation rules [1] on 2014/11/17, allowing usage of 5600 ~
5650 MHz, previously allocated to weather radars, to U-NII applications
with DFS support.
Also, the technical regulations [2] show that for 5470 ~ 5725 MHz U-NII
applications, the peak transmit power shall not exceed the lesser of
250 mW (slightly less than 24 dBm) or 11 dBm + 10log B, where B is the
26dB emission bandwidth in MHz. This is slightly more than 23 dBm for
20 MHz channels.
This patch updates both. Also add links to the two documents into the
database.

I've taken a look at the translation, and as far as I can tell what
you've done looks okay. So go ahead and resend, and as long as no one
else finds a problem I'll apply all 5.

Seth

Indeed. I squashed a fixup into the wrong patch, and tried to fix it.
Obviously that didn't work out so well.

Do you want me to send a new version now, or wait for you to go through
the translation first?

This description doesn't quite match the patches. Patch 4 both adds the
5150-5250 MHz band and increases the power limits for 5250-5350 MHz,
whereas patch 5 changes the DFS master region to DFS-FCC. Previously the
increased power limit for 5250-5350 MHz was part of patch 5 - perhaps
you accidentally moved that part to patch 4 when you were updating the
patches?
So patches 1-3 look fine to me. I suspect you'll want to move the power
limit increase from patch 4 to 5. I'm also going to take a look at a
machine translation of the Chinese document, and if that looks to be in
agreement with your patches then I should be able to apply them next
week sometime.
Thanks,
Seth
Taiwan's frequency allocation rules [1] list the following frequency
ranges available for low power RF devices:
- 2400 ~ 2483.5 MHz
- 5150 ~ 5250 MHz
- 5250 ~ 5350 MHz
- 5470 ~ 5725 MHz
- 5725 ~ 5850 MHz
Update the rules to match. Since 5250 ~ 5350 MHz is wide enough for
VHT80, and there are no regulations against it, enable it as well.
