Use of radio frequencies 2014Published 13.05.2015
In 2014, one of the most significant changes in the use of frequencies was the transfer of 800 MHz frequencies used in TV operations to the use of wireless broadband services.
The objective of frequency planning is to provide users of radio equipment with sufficiently interference-free radio frequencies according to their needs and the general demand. The use of frequencies can best be illustrated by dividing them over different frequency ranges. Most frequencies are used in radio links and radar operations.
Most of low frequencies of 68–1,000 MHz are used in TV distribution focused entirely on this frequency range and in analogue voice radio operations. In 2014, there were changes in this frequency range as the use of wireless broadband networks was started in the 800 MHz range which was previously used in TV operations. A similar change will take place in the 700 MHz range at the beginning of 2017 when TV operations will focus on HD broadcasting in the UHF range and shift to the 470–694 MHz frequency band. The 700 MHz range will also be allocated to the use of wireless broadband networks.
The most significant users of the 1–3 GHz range are mobile communications net-works, but the range is also used for other purposes, such as weather services and maritime radio operations. The 3–6 GHz range is mainly used by fixed-line wireless networks, aviation radio communications, SRD and the military. The highest frequencies of 6–10 GHz are mainly used by radio links, radars and satellites. Save the graph data as a CSV file

In voice radio operations, the number of frequencies allocated to the Finnish Broad-casting Company (Yle) and licensed radio activities has increased slightly from year to year. Particularly, the number of regional and local frequencies has increased. Save the graph data as a CSV file

In 2014, radio links were the largest single user of frequencies. In terms of radio links, operators have continued to replace older narrow bandwidth radio links with higher bandwidth radio links, increasing, not only modulation, but also radio link capacity close to 1 Gbps.
