Hello, I'm wondering if the regulatory DB is up to date for France, especially regarding channels in band 5725-5875 MHz in https://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git/tree/db.txt?id=HEAD I can found (07/09/2017) : country FR: DFS-ETSI ??? (2402 - 2482 @ 40), (20) ??? (5170 - 5250 @ 80), (20), AUTO-BW ??? (5250 - 5330 @ 80), (20), DFS, AUTO-BW ??? (5490 - 5710 @ 160), (27), DFS ??? # 60 GHz band channels 1-4, ref: Etsi En 302 567 ??? (57000 - 66000 @ 2160), (40) which as far as I understands it prevents those frequencies being used. The European Union have taken the following decision : http://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32013D0752&from=EN (or in French : http://eur-lex.europa.eu/legal-content/FR/TXT/PDF/?uri=CELEX:32013D0752&from=FR) where (p14/20, line 61 of the frequencies table) it shoul be allowed in E.U. and the last column states that member countries should reflect thie E.U. decision at national levels regulations before 2014 July 1st. I don't know for other countries, but it seems that France as complied with this, regarding the document from our national agency (ARCEP) : https://www.arcep.fr/uploads/tx_gsavis/14-1263.pdf on page 23/35, the table gives the exact same condition as the E.U. rules. I believe those frequencies should now be allowed in FR regdomain. Also, I own a Synology RT2600AC routeur, and the regional settigns pages allows to set "European Union" which result in the access point broadcastin a "EU" regdom that I can not find in the wireless-regdb Shouldn't it be added in the database ? regards, Mathieu Peyr?ga -- tel : +33 (0)6 87 30 83 59
