to use full power on 6GHz, the router needs to upload its GPS location to a central server to get the available frequencies. Worse than 5GHz in my opinion
I assume that can be also done offline, right? Forcing an intranet device to connect to the outside just to get a list of frequencies would be less than optimal.
There is an exemption for indoor low-power APs, but the manufacturer has to prove that the housing will not survive outdoor weather (usually rain). They have to deliberately make it not-rainproof.
I don't know the situation in the US and I don't think EU administrations require firmwares to be locked at the moment, yet I can tell that requesting locked hardware/firmware is a recurring debate within RF administrations since there were too many abuses (cf. this thread "just tell the hardware to lie" or "just use openwrt to disable DFS" above...) and too many interferences to other services (such as wifi-DFS-disabled interfering with weather-forecast radars). The 6 GHz wifi 6E has to coexist with fixed links, and administrations obviously don't want to repeat the mistakes and issues that are happening today at 5 GHz with radars...
