I'll just give the context why I got interested into those Wifi reguations. I recently bought a DJI Spark UAV, which relies on those exact 5.8 GHz frequencies for controlling, under the WiFi standard (so channels 149 to 165). This is the vendor intended behaviour in any part of the World. The control device can be your regular Android smartphone (that is the client) flying device being the Access point. It happens that many E.U. customers are complaining that this is not working properly (I'm amongst them). When I check which Country Code is broadcasted by the Flying part (access point), I can see "FR" (this is automatically set from GPS onboard the device). My guess is that DJI has some kind of custom "FR" database on the Spark device with those fequencies enabled, but on the client side, most Android phones in E.U. will rely on this code and 802.11d mecanisms and then are not able to use those channels. I understand that this example is probably slightly outside the scope of this mailing list.
