WRC-23, RA-23 and CPM27-1 Outcomes
==================================
Jan 14, 2024 ú News ú IARU R2 News
The ITUïs Radio Assembly (RA-23), World Radio Conference (WRC-23) and
Conference Preparatory Meeting (CPM27-1) concluded their almost 6 week of
activities on December 19 at Dubai, UAE, where overall amateur service fared
very well, despite the enormous pressures across the radio spectrum from LF
to Terahertz. This is a tribute to the IARU team effort, that at times had
to work throughout this period from 8:00 am to as late as beyond 2:00 am and
on weekends.
Top of the amateur radio priority list was the coexistence studies with the
secondary amateur and amateur-satellite allocation with the primary radio
navigation satellite service in 23 cm (AI 9.1 Topic b). This had seen four
years of strenuous effort in the run-up to WRC and resulted in a
recommendation being agreed at the RA-23, followed by WRC-23 agreeing to
mention the recommendation in a new footnote for the allocation, without
incorporation by reference. Both the recommendation and the footnote are
excellent outcome for the amateurs and for the coexistence of both services.
The recommendation, also recognized as guidance, covered the situation
existed in the Region 2. During the study cycle, Inter-American
Contributions and Proposals on that matter were developed by CITEL
(Inter-American Telecommunication Commission) and reflected in the guidance:
the existing spectrum management best practices and technical and
operational measures may be sufficient to ensure protection of the RNSS and,
If needed, other measures may be implemented by administrations based on
their national circumstances, therefore itïs a non-obligatory recommendation
with wide regulatory flexibility, taking account the inexistence of those
interferences in Region 2.
Several other items were relevant to the amateur service and had been
prioritized beforehand:
- The adoption of new allocation to airborne radar sounders in 40?-?50 MHz,
adjacent to 6 m band. Discussions happening in the conference have been
largely limited the operations to the polar area, reducing the risk of
interferences.
- Re-allocations in 231.5?-?252 GHz for Earth Sensing, with positive results
of the secondary and primary segments of the amateur 1 mm band unchanged.
IMT new shared allocations on 3.3 GHz and 10 GHz in Region 2. These are
challenging secondary bands. Instead of a region-wide designation on 3 cm
band for IMT in Region 2, a related footnote was produced limited only to a
few countries. Even administrations from Region 1 had opposed to the IMT
identification, also considering the protection of EESS.
Every WRC agrees to an agenda-setting for the next conference. This theme
had an unprecedented number of proposals for both WRC-27 and preliminary
ones for WRC-31. Following the first battles and agreements before, the IARU
team switched most of its effort to these future proposals to reduce the
impact on the amateur services, since numerous amateur bands were under
previous consideration. Here some of the topics:
- Space Weather Sensors - this potential item was a very concerning proposal,
first considering all bands from 0.1-20 MHz, and other segments that covers
all 10 m, 1.3 m, major part of the 6 m. Concerns were raised by several
countries and strong team effort resulted in these allocations being removed
from the topic.
- Lunar Communications - the future agenda item first will look for new
allocations to the Space Research Service in the Moon, that initially
included 70 cm and bands where some applications like EME potentially could
be restricted. Again, due the teamwork, the UHF aspect of this item was
modified to exclude the 70 cm. By this way, the educational and experimental
Moon sounders build in partnership between universities and amateur radio
institutions will continue to be developed on this band.
For IMT, initially the 3 cm band was again previously included for future
studies worldwide. As the conclusion of the discussions, the band was
withdrawn from another round of consideration for mobile broadband.
Along to the future challenges, we have new studies for Wireless Power
Transfer frequencies, Radiolocation, Space Research, EESS, IMT and
unpredictable proposals that can arise during the next WRC study-cycle that
could affect several bands. In other hand, itïs also planned the study of
possible new allocation in the 275?-?315 GHz range, including for amateur
and amateur-satellite service.
The RA-23, WRC-23 and CPM27-1 outcome is the IARU team also worked
effectively to minimize the possible negative impacts from future studies,
as well took the opportunities for study possible new future bands. This is
again a great result for amateur service from a team effort contributing to
keep a more stable and protected radio allocations to all the operators
worldwide.

At the conclusion of these conferences, IARU is very pleased with the
overall result. The IARU team has already started to discuss and consider
how to engage and resource for the next cycle leading up to WRC-27. IARU
WRC-coordinator and Vice-President Ole Garpestad LA2RR expressed his
pleasure with the results and complimented the extraordinary effort of the
dedicated team of IARU volunteers who worked long hours to achieve the
results that will benefit all amateurs.
Doreen Bogdan-Martin, ITU Secretary-General, mentioned amateur radio in her
speeches at the WRC-23. In the opening remarks, Doreen recalled emergency
communications: "It is amateur radio operators who are able to send damage
reports in the epicenter of an earthquake when all other communication
channels were down". At the closing remarks, she reinforced the
technical-experimental aspects of the service: "We also saw a well-supported
compromise for amateur radio community and, of course, it is always terrific
to see how active that community is. These WRC outcomes will help them
continue to experiment and explore with new technologies, as well a
supporting technical competence development."
A total of 151Member States signed the WRC-23 Final Acts, a record of the
decisions taken at the conference including both the new and revised
provisions of the Radio Regulations. It represents the agreements on
revisions to the global treaty governing the use of the radio frequency
spectrum, both on Earth and in space. "The agreements reached at WRC-23 are
a testament to the unwavering spirit of cooperation and compromise among all
of our members," said Mario Maniewicz, Director of the ITU
Radiocommunication Bureau. "Navigating the complexities of spectrum sharing
to update the Radio Regulations has helped us forge a path that provides a
stable, predictable regulatory environment essential for the development of
innovative radiocommunication services for all".
