Outcome of WRC19

​The outcomes of WRC 19 are as follows;

            AI1.1 –Amateurs at 50MHz

  • to consider an allocation of the frequency band 50-54 MHz to the amateur service in Region 1, in accordance with Resolution 658 (WRC-15)
  • The Plenary approved a secondary allocation of the 50-52 MHz band to the amateur service following the revision of Resolution 12 (on Palestine - which was related to references in the allocation footnotes). A footnote "Different category of service" lists those CEPT countries  where the amateur service will have a primary allocation in the band 50-50.5 MHz with provisions on the protection of the incumbent services in this frequency band. (IRL is not in this Fn) There are other footnotes listing other countries where other variations of the amateur service allocation pertain


    Agenda item 1.2 – ES 400 MHz
  • to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz, in accordance with Resolution 765 (WRC-15)
  • In-band power limits were agreed for EESS and MetSat in 401-403 MHz and MSS in 399.9-400.02 MHz. There are no limits for 400.02- 400.05 MHz which is limited for use by telecommand links


    Agenda item 1.3 – Update EESS/MetSat
  • to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15)
  • No Change was agreed  - this was the only AI were the outcome was "unsatisfactory"
  • Europe had hoped to obtain a primary allocation to the MetSat (space-to-Earth) and the EESS (space-to-Earth) in the frequency band 460‑470 MHz;
  • -whilst ensuring protection of primary services within the band and in adjacent bands with the introduction of regulatory provisions, including relevant pfd masks for GSO and non-GSO satellites, -on the basis that MetSat and EESS earth stations not claim protection from stations in the fixed and mobile services, -and that the priority of MetSat over EESS be retained


    Agenda item 1.4 – Appendix 30 (Annex 7)
  • to consider the results of studies in accordance with Resolution 557 (WRC-15), and review, and revise if necessary, the limitations mentioned in Annex 7 to Appendix 30 (Rev.WRC-15), while ensuring the protection of, and without imposing additional constraints on, assignments in the Plan and the List and the future development of the broadcasting-satellite service within the Plan, and existing and planned fixed-satellite service networks
  • The outcome preferred was to remove or modify the orbital limitations of Annex 7 of Appendix 30. This was obtained


    Agenda item 1.5 – ESIM
  • to consider the use of the frequency bands 17.7-19.7 GHz (s-E) and 27.5-29.5 GHz (E-s) by earth stations in motion communicating with geostationary space stations in the fixed-satellite service and take appropriate action, in accordance with Resolution 158 (WRC-15)
  • A general approach of No Interference from / No Protection of ESIMs on land with respect to terrestrial networks.
  • A pfd limit to be applied for the protection of terrestrial services from aeronautical ESIMs. Two pfd masks  were determined one for below 3000m and another above 3000m
  • Achieved by changes to Article 5, Appendix 4 and a new Resolution


    AI1.6 – Non-GSO FSS Q/V Band
  • to consider the development of a regulatory framework for non-GSO FSS satellite systems that may operate in the frequency bands 37.5-39.5 GHz (s-E), 39.5-42.5 GHz (s-E), 47.2-50.2 GHz (E-s) and 50.4-51.4 GHz (E-s), in accordance with Resolution 159 (WRC-15)#
  • Changes to the limits in Resolution 750 were agreed, with the exception of those for the 36-37 GHz band which will be further studied in the upcoming years. Supplemental links were agreed to be studied in the next study cycle. Protection of GSO MSS is addressed while protection of NGSO MSS needs to be studied and included in the aggregate effect.
  • Transitional measures to protect filings notified before WRC-19 were included in a new Resolution, on the condition that the systems are brought into use before November 2023. New filings require a new co-ordination request process be undertaken.
  • Protection of GSO networks is possible under the umbrella of supplemental links, while NGSO can benefit from the framework for generic links which allows for operation in the Q/V bands



    AI1.7 – Nano/picosatellites
  • to study the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution 659 (WRC-15)
  • a positive outcome facilitates use of the bands 137-138 MHz (space to Earth) and 148–149.9 MHz (Earth to space) by the space operation service associated with short-duration mission satellite systems.
  • This is based on use of the bands by space operation short-duration mission systems on a  non-interference non-protected basis with respect to other primary services in the bands.  A hard limit in the downlink is also set to protect AM(R)S in the adjacent band as well as a pfd limit at the border of 16 countries listed in footnote 5.BB17, acting as a trigger for terrestrial services notified under RR No. 9.21.



    AI 1.8 –Maritime GMDSS

  • Issue A outcome was in line with the European preferences;
  • introduction of MF frequencies for international NAVDAT in RR Article 5 and for the introduction of the HF NAVDAT frequencies in RR Appendix 17
  • Europe opposed the introduction of the MF frequencies for international NAVDAT in RR Appendix 15 and the introduction of the HF NAVDAT frequencies in RR Appendix 15 at this WRC
  • Issue B: Regulatory action due to the introduction of additional satellite systems into the GMDSS by IMO
  • a primary allocation to the mobile maritime-satellite service for both uplink and downlink direction in 5 MHz, namely 1621.35-1626.35 MHz.

  • There was early consensus on the frequency allocations for AMRD group A and AMRD group B that are operated with AIS technology (Group  A channel 70 for digital selective calling and on channels AIS1 and AIS2 for automatic identification system, with Group B in the bands of RR Appendix 18).  A note in the plenary minutes addressed AMRD group B using technology other than AIS.

    AI 1.9.2 –Maritime VDES
  • to consider, based on the results of ITU-R studies
  • 1.9.2 - VDES Satellite modifications of the Radio Regulations, including new spectrum allocations to the maritime mobile-satellite service (Earth to space and space-to-Earth), preferably within the frequency bands 156.0125-157.4375 MHz and 160.6125-162.0375 MHz of Appendix 18, to enable a new VHF data exchange system (VDES) satellite component, while ensuring that this component will not degrade the current terrestrial VDES components, applications specific messages (ASM) and AIS operations and not impose any additional constraints on existing services in these and adjacent frequency bands as stated in recognizing d) and e) of Resolution 360 (Rev.WRC-15)
