How to use frequencies 5400 - 5490 Mhz in Linux?

Question

linux

It is necessary to unblock the use of specified frequencies, is it possible?
Rebuilt wireless-regdb with these frequencies for country 00

* 5805 MHz [161] (15.0 dBm) (no IR)
* 5825 MHz [165] (15.0 dBm) (no IR)

As a result, nothing works anyway, the same airodump-ng, when trying to scan the 5400+ MHz range,
says - no valid freq. given
To check, it was also not possible to create an access point in these frequencies.
Is this an iron problem or can it be solved programmatically?
Thanks for the early.

Everything is good. Your device is operating under the 802.11 standard. The frequencies you are talking about lie between the UNII-2 and UNII-2 Extended blocks and do not have channels allowed for use.
