I'm not sure if there are plans to support S1G in Linux. If not then the information would go unused and untested. If it is supported, then patches are more than welcome. > 2) There's seems to be a missing 160MHz channel (50): > > This combines the restrictions of the two existing defined bands it > overlaps with (https://ttja.ee/eraklient/side-ja-meediateenused/raadioside/wifi-seadmete-kasutus): > > + (5150 - 5350 @ 160), (100 mW), NO-OUTDOOR, DFS, AUTO-BW, wmmrule=ETSI The AUTO-BW flag lets the kernel know that it can combine neighboring rules for wider bandwidth at the lowest power limit within the rules. Thus merging the rules is not needed. Indeed we would prefer rules not be merged, as the database should convey information closest to the regulations. > 3) The 6GHz band should also have an outdoor limit and probably also > allow 320MHz channels (at least in EE): > > - (5945 - 6425 @ 160), (23), NO-OUTDOOR, wmmrule=ETSI > + (5945 - 6425 @ 320), (25 mW), wmmrule=ETSI > + (5945 - 6425 @ 320), (200 mW), NO-OUTDOOR, wmmrule=ETSI The kernel currently can't deal with duplicate rules for the same channel. Thus we have to make a decision on whether to have a rule with higher power but indoor use only, or the opposite. Within our database, we have the former for some jurisdictions and the latter for others. It really depends on the submitter. > Would a patch for these be accepted?

IIUC the EU sets one harmonized regulation but then it's up to each member country to implement / incorporate them? Whether you would like to update other EU countries is up to you. Thanks ChenYu
