23cm band outcome approved at the 7th Plenary meeting of WRC-23

The following was posted today on the global IARU web site:

The International Telecommunication Union’s World Radiocommunication Conference (WRC) began November 20 and continues through December 15, 2023 in Dubai, U​.​A​.​E, for the purpose of reviewing spectrum matters related to the International Radio Regulations. WRC’s are held every three to four years and includes the Amateur and Amateur Satellite Service allocations.

The agenda of items to be reviewed for this WRC was established at the completion of the last conference in 2019. Of primary importance to the Amateur and Amateur Satellite Services is Agenda Item 9.1 topic b to address the amateur services use of the 23cm band and the co-frequency use by several radio navigation satellite service (RNSS) systems in the 1240 – 1300 MHz band.

IARU’s work began four years ago with preparatory study in ITU‑R to address this agenda item and has finally drawn to a close. Our concerted engagement in the ITU‑R working parties, study groups and WRC preparatory meetings ensured that the amateur services were properly represented during the development of two published ITU‑R reports, M.2513 and M.2532. These were followed by an ITU‑R Recommendation, M.2164, that formed the basis for the discussions at WRC-23.

During the WRC-23 deliberations, strong positions were expressed by all the parties involved. The result is a well-supported compromise for a footnote in the Radio Regulations regarding amateur and amateur satellite service operation in the 1240 – 1300 MHz range. The footnote reminds administrations and amateurs of the need to protect the primary RNSS from interference and provides guidance to administrations to allow both services to continue to operate in this portion of the spectrum. The compromise was formally adopted by the Conference Plenary on December 8 and is not subject to further consideration during the final week of the WRC. The IARU team continues its work on other WRC issues including the development of agendas for future conferences.

IARU President Tim Ellam, VE6SH, noted “This is a very good result for the amateur services. The decision reached at WRC-23 on this agenda item makes no change to the table of allocations nor incorporates by reference M.2164 into the Radio Regulations. The addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band.”

The WRC also agreed to suppress the Resolution 774 which closes the issue and satisfies the agenda item.

IARU President Tim Ellam, VE6SH, thanks Barry Lewis, G4SJH, for his success is leading IARU’s work on AI 9.1b. Looking on is (l‑r) Working Party 5A Chair Dale Hughes, VK1DSH, IARU Vice President Ole Garpestad, LA2RR, Tim Ellam, VE6SH, Barry Lewis, G4SJH, and IARU Secretary Joel Harrison, W5ZN

ITU‑R Recommendation M.2164 on 23cm amateur service and RNSS operations now published in time for WRC-23 discussions

As reported on November 20th, the ITU‑R Radio Assembly (RA) met during the week before the World Radio Conference in Dubai. The IARU participated in the meeting and contributed to the development of the draft ITU‑R Recommendation for 23cm band amateur operations alongside the co-frequency radio navigation satellite service (RNSS). The published ITU‑R Recommendation M.2164 is now available and can be found herealong with a summary of the technical conditions here.The recommendation will form a component of the WRC-23 discussions which are ongoing until December 15th relating to WRC-23 agenda item 9.1b.

The final recommendation represents the culmination of more than 4 years of work by the IARU team within the ITU‑R study groups to ensure the best outcome for amateur radio in the face of intense regulatory, political and commercial pressure.

Development of an ITU‑R Recommendation on 23cm amateur band and RNSS operations concludes at ITU‑R Radio Assembly

The ITU‑R Radio Assembly (RA) met during the week before the World Radio Conference in Dubai. The IARU participated in the meeting and contributed to the development of the draft ITU‑R Recommendation for 23cm band amateur operations alongside the co-frequency radio navigation satellite service (RNSS). This has followed a difficult development process in the ITU‑R study groups but the RA achieved a positive outcome with finalisation of ITU‑R Recommendation M.2164. A summary report detailing the meeting activity and some of the tensions dealt with during the meeting is available here.

23cm band report ITU‑R M.2532 published.

As a part of the preparatory process for WRC-23 agenda item 9.1 topic b) involving the 23cm band, ITU‑R Report M.2532 has just been published. This report encapsulates the outcome of resolves 1of ITU‑R Resolution 774 that requires a detailed review of the different systems and applications used by the amateur and amateur satellite services in the 23cm band. The review forms a part of the basis for the studies required by resolves 2to address the amateur and amateur satellite services coexistence with the radio navigation satellite service (RNSS).

The report M.2532 can be found here.

The publication represents a positive outcome from a great deal of work and committment by the IARU volunteer team that has been central to its development since 2019 in ITU‑R Study Group 5.
