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. > * 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.) 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? > * 5725 - 5850 > - 4000 mW e.i.r.p > - 36dBm in every 500 kHz > - DFS > - Outdoor use only > (Since NO-INDOOR flag is not supported by current format, don't add > this entry.) This band is point to point only. TPC is required without provision for no TPC. > These information is from [4], Mobin Aydinfar shared the official link [1] > (inaccessible from outside of Iran), a mirror version [2] and translated > version [3]. > > [1] https://asnad.cra.ir/fa/Public/Documents/Details/73af8590-f065-eb11-968f-0050569b0899 > [2] https://mobintestserver.ir/Iran-2.4Ghz-5Ghz-cra-official-doc.pdf > [3] https://mobintestserver.ir/Iran-2.4Ghz-5Ghz-cra-official-table.ods > [4] https://lore.kernel.org/linux-wireless/c9ccf5ba-c091-45c4-9283-970bfa4f1afe@xxxxxxxxxxxxxxxxxx/T/#u > > Cc: Mobin Aydinfar <mobin@xxxxxxxxxxxxxxxxxx> Please use "Reported-by" instead, and also add Closes: https://lore.kernel.org/linux-wireless/c9ccf5ba-c091-45c4-9283-970bfa4f1afe@xxxxxxxxxxxxxxxxxx/T/#u Thanks ChenYu > Signed-off-by: Ping-Ke Shih <pkshih@xxxxxxxxxxx> > --- > db.txt | 9 ++++++--- > 1 file changed, 6 insertions(+), 3 deletions(-) > > diff --git a/db.txt b/db.txt > index d56ad32d31c9..0189355dff17 100644 > --- a/db.txt > +++ b/db.txt > @@ -934,9 +934,12 @@ country IN: > (5470 - 5725 @ 160), (24), DFS > (5725 - 5875 @ 80), (30) > > -country IR: DFS-JP > - (2402 - 2482 @ 40), (20) > - (5735 - 5835 @ 80), (30) > +# Source: > +# https://asnad.cra.ir/fa/Public/Documents/Details/73af8590-f065-eb11-968f-0050569b0899 > +country IR: DFS-ETSI > + (2400 - 2483.5 @ 40), (100 mW) > + (5150 - 5250 @ 80), (200 mW) > + (5250 - 5350 @ 80), (200 mW), DFS > > # IS as part of CEPT accepted decisions 2005/513/EC (5GHz RLAN, EN 301 893) > # and 2006/771/EC (amended by 2008/432/EC, Short-Range Devices, EN 300 440) > -- > 2.25.1 >
