Wireless audio transmission

Use of wireless microphones and hearing aid equipment in some cases require a license from PTS.

A license is required for wireless audio transmission under the Electronic Communications Act. There are however exceptions where a license is not required. You can read more about what applies to different frequencies in the following table.

Frequency band (MHz)	Licence exemption/licence required	Maximum emission power	Remarks
41–43,6	Exemption	10 mW e.r.p
174–240	Licence required	50 mW e.r.p	Licence can currently be issued until 2030-12-31
470–694	Licence required Find available frequencies through our e-service.	50 mW e.r.p	Licence can currently be issued until 2030-12-31
821,5–826	Exemption	100 mW e.i.r.p	Body-worn
821,5–826	Exemption	20 mW e.i.r.p	Handheld
826–832	Exemption	100 mW e.i.r.p
863–865	Exemption	10 mW e.r.p
1785–1804,8	Exemption	50 mW e.i.r.p	PMSE equipment For body-worn devices or devices that implement frequency scanning
1785–1804,8	Exemption	20 mW e.i.r.p	For other devices

Licences in the 470-694 MHz band

Wireless microphones may currently be used in the 470-694 MHz frequency band in those parts of the band that are not used for terrestrial television broadcasting.

The Government determines which spectrum may be allocated for terrestrial television broadcasting. The current decision regarding spectrum allocation in the 470-694 MHz band applies until 31 December 2033.

Future decisions concerning the use of the band may affect the range of frequencies available for wireless microphones. PTS is monitoring developments and will provide licence holders with timely information about any changes that may affect the use of wireless microphones in the band.

Until further notice, the current rules and conditions for the use of wireless microphones in the 470-694 MHz band remain unchanged.
