APWPT Statement on the World Radiocommunication Conference 2023  

APWPT, Association of Professional Wireless Production Technologies, is looking forward to the World Radiocommunication Conference 2023 (WRC-23) with great concern. At the next World Radiocommunication Conference in autumn 2023, there is another threat of a decision to further reduce the radio frequencies that are absolutely necessary for education, art, culture and event production.   

Due to the decisions of previous World Radiocommunication Conferences, we have already lost the 700 MHz and 800 MHz frequency ranges. To compensate, art, culture and the creative industries had to make considerable investments. This was a task that was hardly feasible, especially for small organizations.  

Now we are facing a new, almost unsolvable problem – the further loss of further radio spectrum would, especially in conurbations, jeopardize future daytime productions and, in addition, the implementation of major events that are very much desired by politicians. This is a business or organizational problem that probably can’t be solved by investment.  

Any change to the existing regulations currently under discussion would have extremely negative consequences. Note: the loss of 600 MHz should not be “trivialized”.  

Our position:  

It must be ensured that broadcasting, education, art, media, film, culture and event production can use sufficiently interference-free frequencies between 470 and 694 MHz on a permanent basis.   

We therefore strongly advocate the retention of the existing and proven system and advocate a no-change for the use of 470 – 694 MHz at WRC23.

APWPT has signed the “Call to Europe 2023”, together with about 100 associations and organizations from media and culture in Europe.

The statement calls for a “no change” vote on agenda item 1.5 at the 2023 World Radiocommunication Conference. The frequency band between 470 and 694 MHZ must continue to be available without restriction for wireless technology (PMSE)!

The wording of the “Call to Europe 2023” can be found here:

This year’s General Meeting will be held virtually on Thursday, September 28, 2023, 13:30 – 15:30 (Berlin time).

Contents: Accountability report of the board, discharge of the board, new election of the board (will be done online in advance of the meeting), World Radiocommunication Conference 2023, among others, discussion.

20 October 2022

Preliminary information on the presentation on 10.11.2022, starting at 10:00 CET

Presentation: Coordination and monitoring of radio frequencies

APWPT, together with many organisations, has over many years participated in event productions and observed spectrum use, including by wireless microphones, their return paths and team communications. This work has been considered in (inter)national working groups and studies.

On 10 November 2022, we will provide updated information, focusing on the UHF TV frequency range. We look forward to your participation, your questions and advice – thank you in advance!

APWPT Chairperson Wolfgang Bilz writes an article in EBU tech-i-magazine, in it:

“In 2008, users and manufacturers of wireless production tools founded APWPT as an international stakeholder group that could speak with one voice. […] Agenda item 1.5 at the next World Radiocommunication Conference, WRC-23, is discussing potential regulatory changes for the 470–694 MHz band. […] APWPT supports the continuation of the successful symbiosis of broadcast and PMSE with no change to the existing rules.”

The “Report on spectrum requirements for Audio PMSE” by Daniel Künzi (Broadcast Wireless Expert SRF, Frequency Management for PMSE Audio, Leader Task Group PMSE SRG) is published here.

According to the results of this report the daily required spectrum for PMSE Audio in the UHF-TV band today is 110 MHz. With this amount of spectrum, the requirement of the most of Campus/Venues and Events can be fulfilled. Nevertheless, for major events the average of the required spectrum is 174 MHz, while the peak demand could be the whole available UHF spectrum of 224 MHz.

14 October 2021

Results of our big survey in 2021: We asked the question, which band is the most used band? (10 frequency bands between 174 to 2.5 GHz were listed).

85 % equipment use is the band 470 – 694 MHz, while the band 694 MHz – 790 MHz is still used by 35 % of the users (although this band will be given to Mobile IMT, it is still usable in many countries).

90 % of the participants stated that the band 470 – 694 MHz is their most preferred band.

PMSE users and manufacturers consider the band 470-694 MHz as the core band of audio PMSE, the access must be ensured beyond 2030. The frequency bands 823-832 and 863-865 MHz are limited in their bandwidth receiving a higher RF noise floor from out-of-band emissions from adjacent bands.

Audio PMSE applications with high quality requirements cannot be supported with the bands above 694 MHz and therefore use only the frequency band 470-694 MHz.

APWPT has been requested by the European ECC (Electronic Communications Committee) Frequency Management FM51 to provide information on available equipment and the percentage use in the available frequency bands as part of its work on use of the 470-694MHz band for WRC 23. This questionnaire is about audio-PMSE (wireless microphones, IEM’s, InterCom, Talkbacks,…) only. The term “audio” covers this range of equipment in the following document.

Please, take part in our survey:
