Radio frequencies – this changes for organizers

The previously used frequencies - between 470 and 694 Mhz will be used for terrestrial television DVB-T from 31 May.

What can be expected

It will become a great challenge to switch permanently installed wireless microphones, audio systems and other production tools to different channels. With DVB-T2, previously used TV channels will no longer be available. At first only the larger metropolitan areas with be affected.


  • increased amount needed for planning and coordination
  • consistent exchange of information needed on the part of technicians
  • many systems probably have to be replaced

The range between 470 and 694 Mhz will continue to be the most important for the entertainment branch. This will be difficult upon the implementation of the changes: there are not enough replacement frequencies available to switch to.

In addition, it is questionable how long the replacement frequencies will be able to be used. The larger the event is, the more transmission links are needed to create the perfect sound for the public. Every wireless microphone (as well as other equipment) needs its own frequency. This will change with the new terrestrial television because there will be far fewer frequencies available. The logical consequence is that large scale event will have to be cancelled.

Even if theatres often work without microphone amplification: can you imagine the stage world without microphones?

Change in radio frequencies

FunkfrequenzenThere will be several more challenges for the event industry before the entire process of switching from DVB-T2 to DVB-T has been completed. That is why all the channels slated to be occupied by television are listed on Save Our Spectrum is an initiative aimed at securing frequency spectrum for the cultural and creative industries. It informs about the threat to wireless products that are immanent by frequency sales.

Problem solving for missing frequencies

Several associations would like to provide their members with software that facilitates precise planning of frequencies despite interference radiation. This software comes from the institute for radio technology (Institut für Rundfunktechnik).
