Probably DFS is required in 5470-5650 MHz range because of 5.450В rule
in [2].

I didn't find any TPC or DFS requirements about this 5725-5850 range.

In fact, I'm not sure at all if document [2] applies to our case. Since the
rules in it regulate the actions for transportable radio navigation services
(used in sea, air, space). So these are additional regulations.

The main rules are described in document [1]. And according to them,
these rules do not apply to Wi-Fi devices, according to
chapter 1, paragraph 1, subparagraph 1. Please read from this paragraph:
http://adilet.zan.kz/rus/docs/V1500010730#z34
Since Wi-Fi devices refer to the table in Appendix 1, I think they are
priority.

I'll send a patch soon.
