How does MT find the national allowed frequencies?

In the ros for my country Spain several frequencies are available for the 5ghz radio band.
Where does MT get that info from?

I have been trying to dig it up on the internet but all I can find is that about 40% of the MT enabled national frequencies for Spain are for military use and some others only for sports(?).

I can´t find how up to date the info is I have found, it could be ages…
There must be a reliable source somewhere?
