Make use of the service to search for frequencies available for wireless microphones within the frequency range 470–694 MHz of the terrestrial digital television. Such frequencies may be individual microphones' centre frequencies released from television operations or the lowest and highest centre frequencies of an available frequency band in the TV-UHF band. The application shows frequencies available for microphones in a selected location. You can search for suitable frequencies by using Traficom's search tool which shows the frequencies released from television operations in a selected location. The frequency suitable for microphones within these bands depends on the location of the user. Therefore, the use of microphones must not cause interference to television reception. The frequency band 470–694 MHz is primarily allocated for television operations and only secondarily for radio microphones. Radio microphones exempted from licensing may only use collective frequencies referred to in Regulation 15. Furthermore, there are licence-exempt radio microphones to be used in the frequencies referred to in section 11.5 of Regulation 15 (DECT equipment) as well as in the 2.4 GHz frequency band referred to in section 10.1 (non-specific short range devices) and section 9.1 (wide-band data transmission equipment) of the Regulation. The frequencies and technical terms of operation of licence-exempt radio microphones can also be found in section 10.5 of Traficom's Regulation 15. When choosing a centre frequency, it must be ensured that the microphone's entire channel width remains within the frequency bands specified above. The user of the microphone can choose the operational frequency but the frequency must be between 174–195 MHz, 216–225 MHz, 470–694 MHz, 823–832 MHz, 863–865 MHz or 1785–1804.8 MHz. Use of licence-exempt microphones in the 174–195 MHz, 216–225 MHz, 470–694 MHz, 823–832 MHz, 863–865 MHz and 1785–1804.8 MHz frequency bandsĪ microphone is exempted from licensing if it only operates on frequencies exempted from licensing.
