This is some dirty bureaucratic language, but summary:
5150-5350 MHz and 5650-5850 MHz -
ONLY for indoor use, without getting additional permissions (according to № 07-20-03-001
http://docs.cntd.ru/document/902048009)
5150-5350 MHz and 5650-6425 Mhz - allowed for outdoor use, but additional permission required. (according to №10-07-02
https://telekom.org.ru/biblioteka/radio ... 6425-mgts/
IMHO regulatory domain info should be updated...
Also: there is some strange channel frequencies, for example, default 20MHz channels begins from 5660 (5650-5670) with 20MHz intervals. This gives us 5720, 5740, 5760 etc, but wiki says it should be 5720, 5745, 5765 etc. (5MHz shift).
I've encountered some compatibilitiy issues already, clients absolutely do not want to connect to 5740/20-Ce Mhz channel. :(
