Do I need a license to use frequencies?

Question

WiFi

If I use a Wi-Fi router to broadcast about 1.2 km, do I need a license to use the frequencies?
One more question. Does the need for a license depend on the frequency of broadcasting? For example, theoretically, in some frequencies, a license may not be needed (eg 2.4GHz; 5GHz). Thank you!

Answer 1

For equipment not certified in Russia, a certificate is required.
Up to 100mW height up to 10m from the fulcrum - registration is not required.
Above 100mW or more than 10m high from the fulcrum - registration with Roskomnadzor is required.
For commercial use, you must obtain a license to provide communication services.
In any case, WiFi frequencies in Russia are assigned, first of all, to the military, if you interfere with them, they will come themselves.
