The International Telecommunication Union (ITU) World Radiocommunication
Conference 2023 (WRC-23) continues through December 15, 2023, in Dubai, United
Arab Emirates (UAE).
IARU's primary effort focused on Agenda Item 9.1 topic b to address amateur use
of the 23-centimeter band and co-frequency use by several radionavigation
satellite service (RNSS) systems in the 1240 - 1300 MHz band.
IARU's work that began 4 years ago with a preparatory study in the ITU
Radiocommunication Sector (ITU-R) to address this agenda item has finally come
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. An ITU-R Recommendation, M.2164, followed these, which
formed the basis for the discussions at WRC-23.
During the WRC-23 deliberations, strong positions were expressed by all 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 it provides guidance
for administrations to allow both services to continue to operate in this
portion of the spectrum.
Administrations are the bodies that govern amateur radio in their respective
countries, such as the Federal Communications Commission (FCC) in the United
States.
The Conference Plenary compromise was formally adopted on December 8 and is not
subject to further consideration during the final week of WRC-23. The IARU team
continues its work on other WRC issues, including developing 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 Resolution 774, which closes the issue and
satisfies the agenda item.
WRC-23 began on November 20[1]. The IARU team includes: ARRL Technical
Relations Specialist John Silverling, WB3ERA; Paul Cloverdale, VE3ICV, for
Radio Amateurs of Canada; Barry Lewis, G4SJH (IARU AI 9.1b Lead), Flavio
