Communications networks (radio spectrum)

Radio spectrum is a natural resource that does not get used up even though more bytes travel through it. For example, mobile communication, wireless broadband, satellite communication, television broadcasting in antenna networks and radio broadcasting all need frequencies in order to be able to provide communication services.

The use of radio spectrum and frequencies is regulated. The frequency area covered by international and national regulations is between 9 kHz and 3,000 GHz. However, financial and technological reasons limit the use of radio spectrum up until 80 GHz. It is estimated that more than 99 per cent of all radio equipment work in frequencies under 10 GHz.

The Ministry of Transport and Communications is responsible for the operation of transport and communications markets and critical communications networks. Guidance in the use of spectrum is provided by the Finnish Communications Regulatory Authority.
