EU WRC23 agenda items consultation and RNSS/23cm band study

The Chair of IARU Region 1 Spectrum and Regulatory Liaison Committee, Barry Lewis G4SJH, reports on the response to the EU WRC-23 consultation and the CEPT RNSS/23cm band study.

On the IARU-R1 site he writes:

In a collaboration between the IARU-R1 Spectrum and Regulatory Liaison Committee (SRLC) and the Political Relations Committee (PRC) an IARU Region 1 response has been provided to the European Union consultation on the WRC23 agenda items.

All the agenda items of interest to the IARU are covered with particular attention paid to the AI9.1b issue on the GALILEO / 23cm band amateur service coexistence. This is an important messaging activity and the IARU response again underlines the IARU view that with only two cases of interference recorded globally, the potential for interference is being over-stated and that any regulatory solutions should be proportionate, realistic and appropriate and should not hinder the future development of amateur services. The IARU would be pleased if member societies could share these same views with their national regulators.

The PRC/SRLC is also developing a response to the European Commission Radio Spectrum Policy Group (RSPG) on the same topics.

Secondly the CEPT project team SE40 that is carrying out the CEPT studies on the RNSS/23cm band topic met during the week 25 – 28th July 2022. The IARU provided a contribution and participated in the meeting supported by USKA. Good progress was made but further work continues to be required to finalise the conclusions from the studies. The IARU continues to be concerned about the lack of consideration being given to the low probability of interference and more work is needed on this aspect. A summary report can be found at

IARU-R1 papers on 23 cm band Amateur/RNSS coexistence

CEPT LogoCEPT SE40 meeting #76 being held April 11-13 is studying the issue of coexistence between amateur radio operation in 1240-1300 MHz and RNSS systems such as Galileo.

One of the Agenda Items for the World Radiocommunication Conference (WRC23) is AI-9.1b – Measures to be applied in the frequency band 1240-1300 MHz to ensure the protection of the radionavigation-satellite service (RNSS) in accordance with Resolution-774.

SE40 is the CEPT ECC working group that looks at Space Service compatibility issues.

IARU Region 1 has submitted these documents to the April meeting:
• Amateur density numbers
• Amateur density numbers Background
• Updated Proposals for WI_39 report

WRC23: 23cm band work continues in CEPT

CEPT CPG WRC23 LogoThe Chair of IARU Region 1 Spectrum Affairs, Barry Lewis G4SJH, reports on the work being done in defending the interests of the Amateur Services in the 1240-1300 MHz band.

On the IARU Region 1 site he writes:

The 4th meeting of the CEPT project team (CPG PTC) tasked with developing the CEPT Brief for WRC23 agenda item 9.1b on 23cm band amateur service and RNSS coexistence took place during March 2022. The IARU R1 was present and provided a contribution to the working document. A summary report describing the contributions and the meeting activity can be found here:
https://www.iaru-r1.org/wp-content/uploads/2022/03/IARU-Report-from-CPG_PTC4r1.pdf

The meeting did not tackle any technical studies directly but the developing brief reports and summarises the activities taking place in other groups where they are being carried out. Updates were made to the background including a description of the work carried out by the amateur community in CEPT and ITU‑R with respect to resolves 1 of the WRC-19 Resolution 774. Further updates were introduced to describe the study work taking place in ITU‑R (WP’s 4C and 5A).

The draft CEPT Brief will undergo further development as technical studies evolve in the wider regulatory community including both CEPT and ITU‑R. The next activity concerning this topic will take place in the CEPT arena (SE40) to progress the technical studies and the draft ECC Report.
