Norges Televisjon (NTV) currently has the right to use the 470 MHz - 790 MHz frequency band to establish a public, electronic communications network based on digital TV (DTT) technology.
In the Free Use Regulations, Nkom has granted the authority to use wireless microphones as a secondary service on the 510 MHz - 790 MHz frequency band. The conditions for use of wireless microphones on this frequency band are therefore that this use does not disturb NTV's legal use of the band.
You can click on the link to finnsenderen.no to the right to find out which frequencies are available at your location.
It is important to note that the list of available frequency resources is only a guide and that it is the user's responsibility to prevent the use of wireless microphones from interrupting the TV broadcasts. Contact Nkom for more information about this arrangement and the use of wireless microphones on the 510 MHz - 790 MHz frequency band.
Nkom emphasises that the purchase of equipment for wireless microphones based on available frequencies on a specific date at a specific geographical area occurs at the buyer's own risk. The buyer does not have the right to compensation from the State if the frequencies are subsequently no longer available and that the equipment can no longer be used in this geographical area.
Regulations concerning the use of wireless microphones
Technical conditions for the use of frequencies for wireless microphones can be found in Chapter 5, Section 14 of the Free Use Regulations. The following frequency ranges can be used without individual licences:
- 41.0-43.6 MHz. Maximum permitted radiated power is 10 mW e.r.p.
- Vacant frequencies in the 510–790 MHz band in accordance with specifications given in the Internet service provided by the Norwegian Communications Authority. Maximum permitted radiated power is 50 mW e.r.p.
- 823–826 MHz. Maximum permitted radiated power is 20 mW e.i.r.p. For body worn equipment the maximum permitted radiated power is 100 mW e.i.r.p.
- 826–832 MHz. Maximum permitted radiated power is 100 mW e.i.r.p.
- 1492–1518 MHz. Restricted to indoor use with a maximum permitted radiated power of 50 mW e.i.r.p.
- 1785–1804.8 MHz. Maximum permitted radiated power is 20 mW e.i.r.p. For body worn equipment the maximum permitted radiated power is 50 mW e.i.r.p.
Use of the frequency bands referred to in a) and f) is authorised in accordance with the frequency use described in the standard EN 300 422. Amplitude modulation is not permitted.
Different users can find suitable frequencies for wireless microphones in these frequency ranges. For example, the 823 – 832 MHz frequency range will be well suited for users with a limited need for microphones/bandwidth.
