Extension of licenses in the 470–694 MHz Band
If you hold a license for wireless audio transmission in the 470–694 MHz frequency band, you will receive a decision from PTS regarding the extension of your license toward the end of 2024. Your extended license will be valid until December 31, 2029.
Please note that as of January 1, 2026, the frequencies you are allowed to use may change. This is due to the government’s upcoming decision regarding which frequencies will be allocated for TV broadcasting within the same frequency band.
In the decisions sent to all license holders for wireless audio transmission in the 470–694 MHz band, it is also stated that the license may be revoked as of January 1, 2026. This formulation is necessary to comply with legal requirements, as we need the ability to revoke the license entirely in order to amend its terms. If such a measure is required, we will take action well in advance of any changes taking effect.
