Proposed Revisions to the Canadian Table of Frequency Allocations 2026 Edition

3. The International Telecommunication Union (ITU) adopts an International Table of Frequency Allocations (the International Table) as part of the ITU Radio Regulations. This International Table allocates spectrum to various combinations of radio services and may include conditions for the use of the spectrum. The International Table is revised, along with other parts of the ITU Radio Regulations, at meetings of the ITU World Radiocommunication Conferences (WRC), which are typically held every four years.

4. The Canadian Table is derived from the International Table and contains those radio services required to meet Canadian needs, among those allocated by the ITU, including the applicable international footnotes. It also contains allocations for services specific to Canada, as well as Canadian footnotes containing additional provisions for their use.

5. ISED revises the Canadian Table periodically, normally following a WRC. WRC-23, which met from November 20, 2023 to December 15, 2023, in Dubai, United Arab Emirates, adopted a number of changes to the frequency allocations in the International Table. WRC-23 dealt with issues, referred to hereafter as agenda items, generally concerning terrestrial and space services. This document discusses the outcomes of WRC-23 for these agenda items and makes proposals for revisions to the Canadian Table. In addition to changes arising from WRC-23, domestic requirements for other changes to the Canadian Table have emerged and will also be addressed.

6. ISED invites public comment on the proposals contained in this consultation paper. Following the review of comments received, allocation decisions will be promulgated by the issuance of a revised Canadian Table.

7. Consequential changes resulting from other decisions taken at WRC-23 (e.g. updated references) that ISED proposes to incorporate into the Canadian Table will be listed in Section 6.6.

8. Since the publication of the most recent edition of the Canadian Table of Frequency Allocations in December 2022, a number of additional spectrum policy decisions have been released that involve domestic allocation or footnote changes. As of the date of publication of this document, the following decisions fall into this category:

• SMSE-012-22, Decision on the Technical and Policy Framework for Radio Local Area Network Devices in the 5850-5895 MHz Band and for Intelligent Transportation Systems in the 5895-5925 MHz Band (December 2022)
• SMSE-018-22, Decision on the Technical and Policy Framework for the Frequency Bands Above 95 GHz (December 2022)
• SPB-001-24, Decision on New Access Licensing Framework, Changes to Subordinate Licensing and White Space to Support Rural and Remote Deployment (January 2024)
• SMSE-001-25, Decision on a Policy, Licensing and Technical Framework for Supplemental Mobile Coverage by Satellite (February 2025)
• SMSE-013-25, Decision on the Policy, Technical and Licensing Framework for the Use of the Frequency Bands 21.2-21.8 GHz and 22.4-23.0 GHz by Fixed Services (December 2025)

9. These decisions were adopted following their respective consultation processes, and ISED will not be considering additional comments as part of this current consultation process. Furthermore, changes to the Canadian Table resulting from these decisions are not reflected in the proposals contained in this consultation paper.

10. It should also be noted that the following spectrum policy consultation processes in which ISED has proposed changes to domestic allocations or footnotes are currently underway:

• SPB-002-25: Consultation on the 26 GHz and 38 GHz Bands
• SMSE-016-25, Consultation on a Policy, Licensing and Technical Framework for Remotely Piloted Aircraft Systems (RPAS) in the 5030-5091 MHz Band and Certain Bands Used to Provide Commercial Mobile Services

11. Consequently, changes to the Canadian Table resulting from recent and upcoming spectrum policy decisions will be incorporated into the revision of the Canadian Table resulting from this consultation process, as appropriate.

12. The proposals contained in this consultation paper are identified as modifications to the current Canadian Table. The tables included in this consultation are drawn from the current Canadian Table and have been numbered for ease of reference. For a better understanding of these proposals, refer to the most recent International Table, as found in the ITU Radio Regulations, Volume 1 (2024 Edition), Article 5 and the World Radiocommunication Conference 2023 (WRC-23) Final Acts. In Section 6, the following conventions are used:

Underlining and highlighting

When used in the Canadian Table, underlining and highlighting proposes the addition of a radio service or footnote. It is also used in the text of Canadian footnotes to identify proposed additional text. The text is highlighted as well as underlined to avoid confusion with hyperlinks in the document.

[Strikeout]

When used in the Canadian Table, struckout text within square brackets proposes the deletion of a radio service or footnote. Struckout text within square brackets is also used in the text of Canadian footnotes to identify proposed deleted text.

5.XXX

This is the designation format of an international footnote.

CXX

This identifies a Canadian footnote.

MOD

This indicates an international footnote modified at WRC-23 or a Canadian footnote proposed for modification. Modifications appear in both the Canadian Table and in the lists of footnotes.

ADD

This is used in a list of footnotes to indicate an international footnote created at WRC-23 or a proposed new Canadian footnote.

ADD MOD

This indicates the proposed addition of an international footnote to the Canadian Table as modified at WRC-23.

SUP

This is used in a list of footnotes to indicate an international footnote suppressed at WRC-23 or a Canadian footnote proposed for suppression.

13. The following is a list of terms and definitions that are relevant to the Canadian Table. These terms and definitions are extracted from the ITU's Radio Regulations. The ITU Radio Regulations should be consulted for a more comprehensive listing.

14. It should be noted that the definition of Coordinated Universal Time (UTC) was modified under WRC-23 agenda item 9.1. This modification is reflected in Section 5.1 below, and further discussed in Section 7.

In the Canadian Table, where a frequency band is indicated as allocated to more than one service, services are listed in the following order:

1. primary services are printed in "all capital letters" (example: MOBILE)
2. secondary services are printed in "normal characters" (example: Mobile)

Additional remarks are printed in "normal characters" (example: MOBILE except aeronautical mobile).

For each category, services are listed in alphabetical order, according to the French language, but that order does not indicate relative priority.

Stations of a secondary service:

1. shall not cause harmful interference to stations of primary service to which frequencies are already assigned or to which frequencies may be assigned at a later date
2. cannot claim protection from harmful interference from stations of a primary service to which frequencies are already assigned or may be assigned at a later date
3. can claim protection, however, from harmful interference from stations of the same or other secondary service(s) to which frequencies may be assigned at a later date

Other conventions used in the Canadian Table

The frequency band referred to in each allocation is indicated in the left-hand top corner of the table concerned.

The footnote references that appear in the tables below the allocated service or services apply to more than one of the allocated services, or the whole of the allocation concerned.

The footnote references that appear to the right of the name of a service, are applicable only to that particular service.

5.4 Regions

These definitions and provisions are extracted from 5.2 to 5.9 of the ITU Radio Regulations.

5.2 For the allocation of frequencies, the world has been divided into three Regions as shown on the following map and described in Nos. 5.3 to 5.9:

 

5.3 Region 1: Region 1 includes the area limited on the east by line A (lines A, B and C are defined below) and on the west by line B, excluding any of the territory of the Islamic Republic of Iran, which lies between these limits. It also includes the whole of the territory of Armenia, Azerbaijan, the Russian Federation, Georgia, Kazakhstan, Mongolia, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the north of Russian Federation, which lies between lines A and C.

5.4 Region 2: Region 2 includes the area limited on the east by line B and on the west by line C.

5.5 Region 3: Region 3 includes the area limited on the east by line C and on the west by line A, except any of the territory of Armenia, Azerbaijan, the Russian Federation, Georgia, Kazakhstan, Mongolia, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the north of Russian Federation. It also includes that part of the territory of the Islamic Republic of Iran lying outside of those limits.

5.6 The lines A, B and C are defined as follows:

5.7 Line A: Line A extends from the North Pole along meridian 40° East of Greenwich to parallel 40° North; thence by great circle arc to the intersection of meridian 60° East and the Tropic of Cancer; thence along the meridian 60° East to the South Pole.

5.8 Line B: Line B extends from the North Pole along meridian 10° West of Greenwich to its intersection with parallel 72° North; thence by great circle arc to the intersection of meridian 50° West and parallel 40° North; thence by great circle arc to the intersection of meridian 20° West and parallel 10° South; thence along meridian 20° West to the South Pole.

5.9 Line C: Line C extends from the North Pole by great circle arc to the intersection of parallel 65° 30' North with the international boundary in Bering Strait; thence by great circle arc to the intersection of meridian 165° East of Greenwich and parallel 50° North; thence by great circle arc to the intersection of meridian 170° West and parallel 10° North; thence along parallel 10° North to its intersection with meridian 120° West; thence along meridian 120° West to the South Pole.

15. The proposed changes to the Canadian Table of Frequency Allocations are organized in each sub-section by the type of service, and then numerically by the particular WRC-23 agenda item number.

6.1 Maritime and aeronautical services

WRC-23, Agenda item 1.7: to consider a new aeronautical mobile-satellite (R) service (AMS(R)S) allocation in accordance with Resolution 428 (WRC-19) for both the Earth-to-space and space-to-Earth directions of aeronautical VHF communications in all or part of the frequency band 117.975-137 MHz, while preventing any undue constraints on existing VHF systems operating in the AM(R)S, the ARNS, and in adjacent frequency bands

Background

16. The frequency band 117.975-137 MHz is used for air traffic management via terrestrial systems operating in the aeronautical mobile (R) service (AM(R)S). To improve coverage and safety in areas where terrestrial services are limited or unavailable, WRC-23 considered a new allocation to the AMS(R)S in this frequency range.

Discussion

17. WRC-23 adopted a new primary AMS(R)S allocation in the entire 117.975-137 MHz frequency band, new footnotes Nos. 5.198A and 5.198B, and modifications to No. 5.200.

18. No. 5.198A establishes that use by the AMS(R)S is subject to coordination under No. 9.11A, with the exclusion of No. 9.16, subject to the newly-modified Resolution 406 (WRC-23), which includes a provision for compatibility between AMS(R)S in the frequency band 117.975-137 MHz and space services in the frequency band 137-138 MHz. No. 5198B establishes that the AM(R)S has priority over the AMS(R)S. Modifications to No. 5.200 were adopted to reflect the new allocation to the AMS(R)S.

19. This is a successful outcome for Canada, as it allocates the full frequency range to the AMS(R)S while providing sufficient protection to incumbent in-band terrestrial AM(R)S and adjacent band services. ISED therefore proposes to adopt these changes within the Canadian Table.

ADD

5.198A The use of the frequency band 117.975-137 MHz by the aeronautical mobile-satellite (R) service is subject to coordination under No. 9.11A. No. 9.16 does not apply. Such use shall be limited to non-geostationary-satellite systems operated in accordance with international aeronautical standards. Resolution 406 (WRC-23) applies. (WRC-23)

ADD

5.198B The use of the frequency band 117.975-137 MHz by the aeronautical mobile (R) service shall have priority over use by the aeronautical mobile-satellite (R) service. (WRC-23)

MOD

5.200 In the frequency band 117.975-137 MHz, the frequency 121.5 MHz is the aeronautical emergency frequency and, where required, the frequency 123.1 MHz is the aeronautical frequency auxiliary to 121.5 MHz. Mobile stations of the maritime mobile service may communicate on these frequencies under the conditions laid down in Article 31 for distress and safety purposes with stations of the aeronautical mobile service and the aeronautical mobile-satellite service. (WRC-0723)

WRC-23, Agenda item 1.11: to consider possible regulatory actions to support the modernization of the Global Maritime Distress and Safety System (GMDSS) and the implementation of e navigation, in accordance with Resolution 361 (Rev.WRC-19)

Background

20. The Global Maritime Distress and Safety System (GMDSS) is a worldwide network of communications systems for emergency communications for ships at sea. The GMDSS enables ships in distress to rapidly alert search and rescue authorities on shore, as well as ships in the vicinity of the ship in distress, in order to receive assistance with a minimum of delay.

21. It is recognized by the international community that there is a continuing need for improved communications to enhance maritime capabilities, and the International Maritime Organization (IMO) is currently considering GMDSS modernization. The IMO is also in the process of implementing e-navigation to enhance berth-to-berth navigation and related services for safety and security at sea and protection of the marine environment

22. Resolution 361 (Rev. WRC-19) called for studies to be carried out by ITU-R, taking into consideration the activities of IMO and other relevant international organizations, in order to determine spectrum needs and regulatory actions to support GMDSS modernization (Issue A), the implementation of e-navigation (Issue B), and the introduction of additional satellite systems into the GMDSS (Issue C). Based on these studies, WRC-23 considered various regulatory actions.

Discussion

23. WRC-23 decided that no regulatory action was required to resolve Issue B. In response to Issue C, WRC-23 adopted No. 5.372A, which provisionally identified a regional GMDSS satellite, which is required to fulfill its coordination requirements before 18 October 2027. As the additional satellite system does not operate in Canadian territory, ISED is proposing to not incorporate this provision into the Canadian Table.

24. In response to Issue A, WRC-23 adopted the new provisions Nos. 5.82D and 5.137A, as well as modifications to Nos. 5.110, 5.132, and 5.228C. These new and modified provisions were adopted to align with the IMO decisions on GMDSS modernization, including amendments to the Safety of Life at Sea (SOLAS) convention chapters III and IV. These amendments aimed to modernize the GMDSS, which prompted technical and regulatory changes, including the deletion of Narrow-Band Direct Printing (NBDP), the introduction of a new Automatic Connection System (ACS) system, and the inclusion of NAVDAT frequencies. WRC-23 also modified No. 5.375 to enable the use of the frequency band 1 645.5-1 646.5 MHz by the mobile-satellite service (Earth-to-space) and for inter-satellite links for urgency communications, in addition to the distress and safety communications which had previously been authorized. ISED proposes to incorporate these new and modified provisions into the Canadian Table.

ADD

5.82D When establishing coast stations in the NAVDAT system on the frequencies 500 kHz and 4 226 kHz, the conditions for the use of the frequencies 500 kHz and 4 226 kHz are prescribed in Articles 31 and 52. Administrations are strongly recommended to coordinate the NAVDAT systems operating characteristics in accordance with the procedures of the International Maritime Organization (IMO) (see Resolution 364 (WRC-23).

MOD

5.110 The frequencies 2 174.5 kHz, 4 177.5 kHz, 6 268 kHz, 8 376.5 kHz, 12 520 kHz and 16 695 kHz are international distress frequencies for narrow-band direct-printing telegraphy. The conditions for the use of these frequencies are prescribed in Article 31. used for the automatic connection system (ACS), as described in the most recent version of Recommendation ITU-R M.541. (WRC-23)

MOD

5.132 The frequencies 4 210 kHz, 6 314 kHz, 8 416.5 kHz, 12 579 kHz, 16 806.5 kHz, 19 680.5 kHz, 22 376 kHz and 26 100.5 kHz are the international frequencies for the transmission of maritime safety information (MSI) (see Appendix Appendices 15 and 17. (WRC-23)

ADD

5.137A The frequencies 6 337.5 kHz, 8 443 kHz, 12 663.5 kHz, 16 909.5 kHz and 22 450.5 kHz are the regional frequencies for the transmission of MSI by means of the NAVDAT system (see Appendices 15 and 17). (WRC-23)

MOD

5.228C The use of the frequency bands 161.9625-161.9875 MHz and 162.0125-162.0375 MHz by the maritime mobile service and the mobile-satellite (Earth-to-space) service is limited to the automatic identification system (AIS), including AIS search and rescue transmitters (AIS-SART) and satellite emergency position indicating radio beacons with AIS (EPIRB-AIS). The use of these frequency bands by the aeronautical mobile (OR) service is limited to AIS emissions from search and rescue aircraft operations. The AIS, AIS-SART and EPIRB-AIS operations in these frequency bands shall not constrain the development and use of the fixed and mobile services operating in the adjacent frequency bands. (WRC-1223)

MOD

5.375 The use of the band 1 645.5 – 1 646.5 MHz by the mobile-satellite service (Earth-to-space) and for inter-satellite links is limited to distress, urgency and safety communications (see Article 31). (WRC-23)

6.2 Mobile, fixed, and amateur services

WRC-23, Agenda item 1.2: to consider identification of the frequency bands 3 300-3 400 MHz, 3 600‑3 800 MHz, 6 425-7 025 MHz, 7 025-7 125 MHz and 10.0-10.5 GHz for International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 245 (WRC‑19)

Background

25. The continued evolution of International Mobile Telecommunications (IMT), which provides wireless telecommunication services on a worldwide scale, has generated significant economic and social benefits. Overall data demand and the number of connected devices are expected to continue to grow significantly. While some spectrum bands below 3 GHz are identified for IMT, and several frequency bands were identified above 24 GHz at WRC-19, efforts to identify additional mid-band spectrum for IMT have persisted. As such, WRC-23 agenda item 1.2 proposed to identify additional frequency bands for IMT in the 3 GHz – 10.5 GHz range.

Discussion

26. WRC-23 adopted regulatory text to identify several frequency ranges for IMT on a global and regional basis, with implications for Canada as follows:

MOD

5.434 In Canada, Chile, Colombia, Costa Rica, El Salvador, the United States and ParaguayRegion 2, the frequency band 3 600-3 700 MHz, or portions thereof, is identified for use by these administrations wishing to implement International Mobile Telecommunications (IMT). This identification does not preclude the use of this frequency band by any application of the services to which it is allocated and does not establish priority in the Radio Regulations. At the stage of coordination the provisions of Nos. 9.17 and 9.18 also apply. Before an administration brings into use a base or mobile station of an IMT system, it shall seek agreement under No. 9.21 with other administrations and ensure that the power flux-density (pfd) produced at 3 m above ground does not exceed −154.5 dB(W/(m2 · 4 kHz)) for more than 20% of time at the border of the territory of any other administration. This limit may be exceeded on the territory of any country whose administration has so agreed. In order to ensure that the pfd limit at the border of the territory of any other administration is met, the calculations and verification shall be made, taking into account all relevant information, with the mutual agreement of both administrations (the administration responsible for the terrestrial station and the administration responsible for the earth station), with the assistance of the Bureau if so requested. In case of disagreement, the calculation and verification of the pfd shall be made by the Bureau, taking into account the information referred to above. Stations of the mobile service, including IMT systems, in the frequency band 3 600-3 700 MHz shall not claim more protection from space stations than that provided in Table 21-4 of the Radio Regulations (Edition of 2004). Administrations wishing to implement IMT shall obtain the agreement of neighbouring countries to ensure the protection of the fixed-satellite service (space-to-Earth). (WRC-1923)

ADD

5.435B In the Bahamas, Belize, Brazil, Canada, Colombia, Costa Rica, United States, Guatemala, the French overseas departments and communities in Region 2, Greenland, the overseas countries and territories within the Kingdom of the Netherlands in Region 2, Paraguay, Peru, Trinidad and Tobago and Uruguay, the frequency band 3 700-3 800 MHz is identified for use by any of these administrations wishing to implement International Mobile Telecommunications (IMT). This identification does not preclude the use of this frequency band by any application of the services to which it is allocated and does not establish priority in the Radio Regulations. Administrations wishing to implement IMT shall obtain the agreement of neighbouring countries to ensure the protection of the fixed-satellite service (space-to-Earth). (WRC-23)

WRC-23, Agenda item 1.4: to consider, in accordance with Resolution 247 (WRC 19), the use of high-altitude platform stations as IMT base stations (HIBS) in the mobile service in certain frequency bands below 2.7 GHz already identified for IMT, on a global or regional level

Background

27. High-altitude platform stations (HAPS) as IMT base stations (HIBS) have the ability to cover a large footprint at low latency, and could contribute to increased resiliency for terrestrial IMT networks. HIBS could use the same frequency bands as ground-based IMT base stations in order to provide mobile-broadband connectivity to underserved communities, including in rural and remote areas, in areas where it is not practical to deploy towers, or where there is a need to cover larger areas.

28. WRC-23 considered measures to identify certain frequency bands already identified for IMT for the use of HIBS, as well as modifications to conditions for use of HIBS in frequency bands already identified for that use.

29. It should be noted that ISED has published two spectrum policy decisions involving changes to the Canadian Table in some frequency ranges also implicated under WRC-23 agenda item 1.4.

30. Through SPB-001-24, Decision on New Access Licensing Framework, Changes to Subordinate Licensing and White Space to Support Rural and Remote Deployment, ISED decided to upgrade the existing secondary allocations to the FS in the frequency bands 824-849 MHz and 869-890 MHz to primary allocations. ISED also adopted a new Canadian footnote applying to the secondary allocation to the FS in the frequency band 935-941 MHz.

31. Through SMSE-001-25, Decision on a Policy, Licensing and Technical Framework for Supplemental Mobile Coverage by Satellite, ISED decided to remove the international footnote No. 5.317 from the Canadian Table. In addition, new secondary MSS allocations were adopted, via a new Canadian footnote, in the following frequency bands under discussion for WRC-23 agenda item 1.4:

• 663-698 MHz (Earth-to-space) and 617-652 MHz (space-to-Earth),
• 698-716 MHz (Earth-to-space) and 728-746 MHz (space-to-Earth),
• 716-728 MHz (space-to-Earth),
• 777-787 MHz (Earth-to-space) and 746-756 MHz (space-to-Earth),
• 824-849 MHz (Earth-to-space) and 869-894 MHz (space-to-Earth),
• 1850-1915 MHz (Earth-to-space) and 1930-1995 MHz (space-to-Earth), and
• 1710-1780 MHz (Earth-to-space) and 2110-2180 MHz (space-to-Earth).

32. In addition to the spectrum policy decisions noted above, ISED has also published the spectrum policy consultation SMSE-016-25, Consultation on a Policy, Licensing and Technical Framework for Remotely Piloted Aircraft Systems (RPAS) in the 5030-5091 MHz Band and Certain Bands Used to Provide Commercial Mobile Services, which proposes the addition of a new Canadian footnote to the following frequency bands:

• 617-652 MHz and 663-698 MHz,
• 698-756 MHz and 777-787 MHz,
• 1850-1915 MHz and 1930-1995 MHz,
• 1710-1755 MHz and 2110-2155 MHz, and
• 1755 MHz-1780 MHz and 2155-2180 MHz.

33. The changes resulting from SPB-001-24 and SMSE-001-25 will be reflected in the next revision of the Canadian Table, concurrently with any changes proposed below that are adopted following the conclusion of the present consultation process.

Discussion

34. WRC-23 adopted footnote 5.312B, which identified the 694-960 MHz frequency band for HIBS in Region 1 and the 698-960 MHz frequency band in Region 2. WRC-23 also adopted footnote 5.409A, which identified the 2500-2690 MHz frequency band for HIBS in Regions 1 and 2, and the 2500-2655 MHz frequency band in Region 3.

35. Furthermore, WRC-23 modified footnote 5.388A to include a HIBS identification for the frequency band 1710-1885 MHz, in addition to those already identified in that footnote. Modifications to 5.388A also included amendments to the conditions for use of HIBS.

36. Finally, WRC-23 modified Resolution 221 (Rev. WRC-23) to update the conditions for use of HIBS in the frequency bands 1 885-1 980 MHz, 2 010-2 025 MHz, and 2 110-2 170 MHz. The updated conditions include appropriate measures to ensure protection of incumbent services, both in-band and in adjacent bands.

37. The results are in line with the Canadian objectives of ensuring the protection of incumbent operations, both in-band and in adjacent bands, while also providing for global harmonization for the use of HIBS in several frequency bands.

38. ISED proposes to incorporate footnotes 5.312B, 5.409A and 5.388A adopted at WRC-23 into the Canadian Table. However, in view of the designation of the frequency range 902 – 928 MHz for industrial, scientific and medical (ISM) applications as per No. 5.150, ISED proposes to omit the reference to No. 5.312B from that range in the Canadian Table. Furthermore, given that Canadian footnote C5 designates the frequency band 1 780 – 1 850 MHz for the exclusive use of the Government of Canada, ISED proposes not to adopt the modified No. 5.388A in that frequency range. In addition, as spectrum utilization policies regarding the use of HIBS have yet to be established in Canada, ISED also proposes to adopt a new Canadian footnote C7A, which clarifies that use of HIBS will be the subject of spectrum policies which will be formulated in the future.

ADD

5.312B The frequency band 698-960 MHz, or portions thereof, in Region 2, and the frequency band 694-960 MHz, or portions thereof, in Region 1, are identified for use by high-altitude platform stations as International Mobile Telecommunications (IMT) base stations (HIBS). This identification does not preclude the use of these frequency bands by any application of the services to which they are allocated and does not establish priority in the Radio Regulations. Resolution 213 (WRC-23) shall apply. HIBS shall not claim protection from existing primary services. No. 5.43A does not apply, see resolves 2 of Resolution 213 (WRC-23). Such use of HIBS in the frequency bands 694-728 MHz, 830-835 MHz and 805.3-806.9 MHz is limited to reception by HIBS. (WRC-23)

5.388A The frequency bands 1 710-1 980 MHz, 2 010-2 025 MHz and 2 110-2 170 MHz Iin Regions 1 and 3, and the frequency bands 1 885-1 980 MHz, 2 010-2 025 MHz and 2 110-2 170 MHz and, in Region 2, the bands 1 885710-1 980 MHz and 2 110-2 160 MHz in Region 2 may be used are identified for the use by high altitude platform stations as base stations to provide International Mobile Telecommunications (IMT) base stations (HIBS), in accordance with Resolution 221 (Rev.WRC-07). Their use by IMT applications using high altitude platform stations as base stations This identification does not preclude the use of these frequency bands by any station application inof the services to which they are allocated and does not establish priority in the Radio Regulations. Resolution 221 (Rev.WRC-23) shall apply. HIBS shall not claim protection from existing primary services. No. 5.43A does not apply. Such use of HIBS in the frequency bands 1 710-1 785 MHz in Regions 1 and 2, and 1 710-1 815 MHz in Region 3 is limited to reception by HIBS, and in the frequency band 2 110-2 170 MHz is limited to transmission from HIBS. (WRC-1223)

ADD

5.409A The frequency band 2 500-2 690 MHz in Regions 1 and 2, and the frequency band 2 500-2 655 MHz in Region 3 are identified for use by high-altitude platform stations as International Mobile Telecommunications (IMT) base stations (HIBS). This identification does not preclude the use of these frequency bands by any application of the services to which they are allocated and does not establish priority in the Radio Regulations. Resolution 218 (WRC-23) shall apply. HIBS shall not claim protection from existing primary services. No. 5.43A does not apply.

6.3 Science services

WRC-23, Agenda item 1.12: to conduct, and complete in time for WRC-23, studies for a possible new secondary allocation to the Earth exploration-satellite service (active) for spaceborne radar sounders within the range of frequencies around 45 MHz, taking into account the protection of incumbent services, including in adjacent bands, in accordance with Resolution 656 (Rev.WRC-19)

Background

39. Spaceborne radar sounders, operating in the Earth exploration-satellite service (EESS), enable the gathering of data about the planet's sub-surface structure, contributing to studies on climate change and assisting administrations in their assessment of sub-surface water resources within their territories. Under WRC-23 agenda item 1.12, the Conference considered possible secondary allocations to the EESS (active) for spaceborne radar sounders in the 45 MHz frequency range.

Discussion

40. WRC-23 decided to add a new secondary allocation to the EESS (active) in the 40-50 MHz frequency band. WRC-23 also adopted footnote 5.159A, which references the newly adopted Resolution 677 (WRC-23), limiting the use of the EESS (active) to polar regions, including Greenland, as well as imposing technical and regulatory constraints to protect incumbent services in-band and in adjacent bands. These results align with Canadian objectives, and ISED is therefore proposing to incorporate these changes into the Canadian Table.

ADD

5.159A The use of the frequency band 40-50 MHz by the Earth exploration-satellite service (active) shall be in accordance with the geographical area restrictions and the operational and technical conditions defined in Resolution 677 (WRC-23). The provisions of this footnote in no way diminish the obligation of the Earth exploration-satellite service (active) to operate as a secondary service in accordance with Nos. 5.29 and 5.30. (WRC-23)

WRC-23, Agenda item 1.13: to consider a possible upgrade of the allocation of the frequency band 14.8-15.35 GHz to the space research service, in accordance with Resolution 661 (WRC‑19)

Background

41. The space research service (SRS) supports various scientific applications such as space probes and scientific research satellites. Prior to WRC-23, the Radio Regulations included a secondary allocation to the SRS in the frequency band 14.8-15.35 GHz, with fixed and mobile services having primary status in the band. Existing operations in this band under the SRS include data relay satellites in intersatellite links and existing high-speed data links from non-geostationary satellites.

42. This secondary allocation had not been incorporated into the Canadian Table, which currently allocates the frequency band 14.8-15.35 GHz to the fixed service (FS) on a primary basis, and to the mobile service (MS) on either a primary or secondary basis, depending on the specific frequency range. Canadian footnote C5 designates the mobile service in the frequency band 14.66-15.35 GHz for the exclusive use of the Canadian government, and Canadian footnote C41 designates the frequency bands 14.66-14.82 GHz and 15.135-15.295 GHz for government-exclusive aeronautical mobile applications in the mobile service.

43. Prior to WRC-23, SRS operators had sought additional regulatory certainty in order to be able to ensure long-term operation of systems in this service. Under agenda item 1.13, WRC-23 considered the possibility of upgrading the SRS from secondary to primary status in the band in order to enable the development and protection of new research satellites with the capability of broadband communication downlinks in the SRS.

Discussion

44. WRC-23 decided to upgrade the SRS allocation in the 14.8-15.35 GHz frequency band to primary status, and adopted the new footnote No. 5.510A limiting the use of the frequency band to SRS missions operating near Earth in all directions, with other uses of the frequency band by the SRS to operate on a secondary basis. WRC-23 also adopted a new Resolution 678 (WRC-23) to set out technical rules to protect incumbent services from the SRS in the frequency band 14.8-15.35 GHz.

45. As mentioned previously, Canada has not incorporated the secondary allocation to the SRS into the Canadian Table. However, with the limits to SRS operations in No. 5.510A and Resolution 678 (WRC-23), incumbent services in the 14.8-15.35 GHz and adjacent frequency bands will be sufficiently protected from systems operating under the upgraded primary SRS allocation. ISED is therefore proposing to adopt the primary allocation to the SRS in 14.8-15.35 GHz in the Canadian Table along with the associated No. 5.510A.

ADD

5.510A The allocation of the frequency band 14.8-15.35 GHz to the space research service on a primary basis is limited to satellite systems operating in the space-to-space, space-to-Earth and Earth-to-space directions at distances from the Earth of less than 2 × 10⁶ km in accordance with Resolution 678 (WRC-23). Other uses of the frequency band by the space research service are on a secondary basis. The use of the frequency band 14.8-15.35 GHz by the space research service (space-to-Earth) (Earth-to-space) is on a secondary basis with respect to the terrestrial services in Algeria, Saudi Arabia, Bahrain, Korea (Rep. of), Egypt, the United Arab Emirates, the United States, India, Iraq, Japan, Kuwait, Libya, Morocco, Mauritania, Oman, Qatar, the Syrian Arab Republic, Tunisia and Yemen. (WRC-23)

WRC-23, Agenda item 1.14: to review and consider possible adjustments of the existing frequency allocations or possible new primary frequency allocations to the Earth exploration-satellite service (passive) in the frequency range 231.5-252 GHz, to ensure alignment with more up-to-date remote-sensing observation requirements, in accordance with Resolution 662 (WRC-19)

Background

46. Microwave remote sensing instruments operating in the EESS (passive) service allow for the measurement of various atmospheric processes and compounds, such as ice clouds, nitric acid, ozone, sulphur dioxide, and isotopic oxygen, enhancing Numerical Weather Prediction (NWP). Canada makes extensive use of this data, which is distributed worldwide through the World Meteorological Organization (WMO). The allocations to the EESS (passive) in 231.5-252 GHz were adopted decades ago, at a time when operational requirements for these applications were unclear. Under agenda item 1.14, WRC-23 reviewed these allocations, taking into account scientific and technological developments for passive microwave sensor measurements, to ensure that the allocations to EESS (passive) within this frequency range correspond to the observation requirements for satellite passive microwave sensing.

47. At WRC-23, Canada supported modifications to the EESS (passive) allocations in this frequency range to correspond to current operational requirements for satellite passive microwave sensing instruments, while appropriately addressing potential impacts on other primary services.

48. It should be noted that, through the publication of SMSE-018-22, Decision on the Technical and Policy Framework for the Frequency Bands Above 95 GHz, ISED adopted a new Canadian footnote applying to the 244 – 246 GHz frequency range. This change will be reflected in the next revision of the Canadian Table, concurrently with any changes proposed below that are adopted following the conclusion of the present consultation process.

Discussion

49. WRC-23 adopted a new primary allocation to EESS (passive) in the 239.2-242.2 GHz and 244.2-247.2 GHz frequency bands. In addition, the FS and MS allocations in the 239.2-241 GHz frequency band were removed, with new allocations to the FS and MS added to 235-238 GHz. WRC-23 also adopted No. 5.563AA, establishing that EESS shall not claim protection from FS and MS in 235-238 MHz.

50. The results of this agenda item are consistent with Canada's position prior to the Conference, and will allow Canada to benefit from improved EESS data. Furthermore, fixed and mobile services are gaining additional spectrum with the assurance that their future needs will be fully protected through the regulatory provisions adopted at the Conference. ISED therefore proposes to incorporate these changes into the Canadian Table. As a consequence of adopting these changes, references to No. 5.138 would be removed from the Canadian Table in the newly-created 241-242.2 GHz and 247.2-248 GHz rows as the footnote does not pertain to those frequency ranges.

ADD

5.563AA In the frequency band 235-238 GHz, stations in the Earth exploration-satellite service (passive) shall not claim protection from stations in the fixed and mobile services. (WRC-23)

6.4 Satellite services

WRC-23, Agenda item 1.15: to harmonize the use of the frequency band 12.75-13.25 GHz (Earth-to-space) by earth stations on aircraft and vessels communicating with geostationary space stations in the fixed-satellite service globally, in accordance with Resolution 172 (WRC-19)

Background

51. Earth stations in motion (ESIMs) are moving earth stations such as aircraft, ships and vehicles that communicate with space stations in the fixed-satellite service (FSS). ESIMs are able to operate within the envelope of the characteristics of typical FSS earth stations. WRC-03 adopted regulatory provisions to enable earth stations on board vessels in the frequency bands 5925-6425 MHz and 14-14.5 GHz. WRC-15 subsequently adopted provisions for GSO ESIM in the bands 17.7-19.7 and 27.5-29.5 GHz. At WRC-19, provisions were established for the operations of GSO ESIMs in the band 17.719.7 GHz and 27.529.5 GHz.

52. The frequency band 12.75‑13.25 GHz is allocated to FSS (Earth-to-space) and is used by the geostationary (GSO) FSS in accordance with the provisions of Appendix 30B. The allocation can also be used by non-GSO satellite systems under the condition of not claiming protection from GSO satellite networks as per No. 5.441. Internationally, but not in Canada, the band is also allocated to fixed and mobile services on a primary basis and to space research deep space (space-to-Earth) on a secondary basis.

53. Under agenda item 1.15, WRC-23 considered the possibility of allowing GSO ESIMs to operate in the frequency bands 12.75‑13.25 GHz. Canada's objective was to ensure protection of non-GSO FSS systems as well as fixed and mobile services, and to ensure that any regulatory changes did not negatively affect Canadian operations.

Discussion

54. WRC-23 adopted a new provision, No. 5.496A, enabling the use of aeronautical and maritime ESIMs communicating with geostationary satellites in the 12.75-13.25 GHz frequency band. Such use is subject to Resolution 121 (WRC-23), which includes a notification procedure for ESIMs for the protection of assignments in the Appendix 30B List, provisions relating to the responsibilities of administrations in case of unacceptable interference, limits for the protection of incumbent services, and a methodology for examining the compliance of ESIMs with pfd limits.

55. Through its May 2022 Decision on Updates to the Licensing and Fee Framework for Earth Stations and Space Stations in Canada, ISED adopted a generic Earth station licensing framework for ESIMs. As part of the decision, the frequency band 12.75-13.25 GHz was not identified for generic Earth station licensing. While ISED proposes to adopt No. 5.496A into the Canadian Table, given the importance of 12.75-13.25 GHz as a "planned band" set aside to facilitate equitable access by ITU member states to GSO FSS orbital spectrum under Appendix 30B, ISED does not intend to allow generic earth station licensing in the frequency band at this time. ISED will monitor international developments and amend its spectrum policies as appropriate.

ADD

5.496A The frequency band 12.75-13.25 GHz (Earth-to-space) may be used by earth stations in motion, limited to earth stations on aircraft and vessels, communicating with geostationary space stations in the fixed-satellite service. Resolution 121 (WRC-23) shall apply. (WRC-23)

WRC-23, Agenda item 1.16: to study and develop technical, operational and regulatory measures, as appropriate, to facilitate the use of the frequency bands 17.7-18.6 GHz, 18.8-19.3 GHz and 19.7-20.2 GHz (space-to-Earth) and 27.5-29.1 GHz and 29.5-30 GHz (Earth-to-space) by non-geostationary fixed-satellite service earth stations in motion, while ensuring due protection of existing services in those frequency bands, in accordance with Resolution 173 (WRC-19)

Background

56. In order to enable broadband communication with users on vessels, aircraft and vehicles with non-GSO satellite systems, WRC-23 considered agenda item 1.16 to study the possibility of allowing non-GSO ESIMs to operate in the frequency bands 17.7-18.6 GHz, 18.8-19.3 GHz, 19.7-20.2 GHz, 27.5-29.1 GHz and 29.5-30 GHz. Under this agenda item, WRC-23 also considered measures to protect other services allocated in these frequency bands, including fixed, mobile, meteorological-satellite, and GSO fixed-satellite services. Measures to protect EESS (passive) operations in adjacent frequency bands were also considered.

57. Canada's objective at WRC-23 was to enable the operation of ESIMs communicating with non-GSO satellites, while ensuring the protection of incumbent services. Canada also sought to include provisions establishing clear responsibilities for administrations in regards to resolving instances of unacceptable interference.

Discussion

58. WRC-23 adopted a new footnote No. 5.517B, enabling the use of ESIMs communicating with non-geostationary satellites in the 17.7-18.6 GHz, 18.8-19.3 GHz, 19.7-20.2 GHz (space-to-Earth), 27.5-29.1 GHz and 29.5-30 GHz (Earth-to-space) frequency bands. Such use is subject to Resolution 123 (WRC-23), which includes provisions related limits for the protection of incumbent services, including the protection of EESS (passive) in the adjacent 18.6-18.8 GHz frequency band. Resolution 123 (WRC-23) also includes provisions setting out the responsibilities of administrations in resolving instances of unacceptable interference, and minimum requirements for non-GSO ESIMs. These results are in line with Canada's objectives and ISED is proposing to adopt No. 5.517B into the Canadian Table.

ADD

5.517B The operation of aeronautical and maritime earth stations in motion communicating with non-geostationary space stations in the fixed-satellite service in the frequency bands 17.7-18.6 GHz, 18.8-19.3 GHz and 19.7-20.2 GHz (space-to-Earth) and 27.5-29.1 GHz and 29.5-30 GHz (Earth-to-space) shall be subject to the application of Resolution 123 (WRC-23) (WRC-23)

WRC-23 Agenda Item 1.17: to determine and carry out, on the basis of ITU-R studies in accordance with Resolution 773 (WRC-19), the appropriate regulatory actions for the provision of inter-satellite links in specific frequency bands, or portions thereof, by adding an inter-satellite service allocation where appropriate

Background

59. Science services such as Earth exploration, space research and space operations have limited numbers of satellites and earth stations, which affect their ability to transmit large amounts of data to Earth in real-time. Inter-satellite links permit data transmissions between satellites, allowing data to be relayed to satellites with better visibility of their associated earth stations, ultimately enabling faster transmission of data to Earth.

60. Under agenda item 1.17, WRC-23 considered the feasibility of enabling inter-satellite links through an allocation to the inter-satellite service to allow for transmissions directly between scientific non-geostationary satellites and other non-GSO or GSO satellites. The agenda item examined appropriate technical, operational and regulatory provisions for satellite-to-satellite links in the frequency bands 11.7-12.7 GHz, 18.1-18.6 GHz, 18.8-20.2 GHz and 27.5-30 GHz, while protecting incumbent services including the FSS, the FS, and the MS.

61. Canada's objective at WRC-23 was to seek an Inter Satellite Service (ISS) allocation, under appropriate conditions to protect incumbent services, in order to enable scientific data and applications to be more quickly and frequently transmitted to Earth.

Discussion

62. WRC-23 adopted new primary ISS allocations in the 18.1-18.6 GHz, 18.8-20.2 GHz, and 27.5-30 GHz frequency bands. WRC-23 also adopted No. 5.521A and Resolution 679 (WRC-23), which set out conditions for use of these frequency bands by GSO and non-GSO space stations operating in the ISS, including limiting such use to space research, space operation and/or Earth exploration-satellite applications, as well as transmissions of data originating from industrial and medical activities in space. WRC-23 also adopted No. 5.523DA, which provides a power flux-density limit for space stations operating in the inter-satellite service operating in the frequency band 19.3-19.7 GHz, in order to protect feeder links of non-geostationary networks in the MSS operating in that frequency band. As studies did not support use of the band 11.7-12.7 GHz for space-to-space links, no ISS allocation was adopted in that frequency band.

ADD

5.521A For use of the frequency bands 18.1-18.6 GHz, 18.8-20.2 GHz and 27.5-30 GHz, or parts thereof, by space stations in the inter-satellite service, Resolution 679 (WRC-23) shall apply. Such use is limited to space research, space operation and/or Earth exploration-satellite applications, and also transmissions of data originating from industrial and medical activities in space. When using these frequencies, administrations shall ensure that this inter-satellite service is used only for the aforementioned purposes and is not subject to coordination under No. 9.11A. For use of the frequency bands 18.1-18.6 GHz, 18.8-20.2 GHz, 27.5-29.1 GHz and 29.5-30 GHz by space stations, the allocation is limited to inter-satellite links between non-geostationary satellites or between non-geostationary satellites and geostationary satellites. For use of the frequency band 29.1-29.5 GHz by space stations, the allocation is limited to inter-satellite links between non-geostationary satellites and geostationary satellites. No. 4.10 does not apply. (WRC-23)

ADD

5.523DA In order to protect feeder links of non-geostationary networks in the mobile-satellite service in the frequency band 19.3-19.7 GHz, the power flux-density values produced at the surface of the Earth for all angles of arrival by a space station in the inter-satellite service operating in this band in accordance with Resolution 679 (WRC-23) shall not exceed −140 dB(W/m²) in any 1 MHz within 150 km of any of the above feeder-link earth stations recorded in the Master International Frequency Register. (WRC-23)

WRC-23 Agenda Item 1.19: to consider a new primary allocation to the fixed-satellite service in the space-to-Earth direction in the frequency band 17.3-17.7 GHz in Region 2, while protecting existing primary services in the band, in accordance with Resolution 174 (WRC 19)

Background

63. Prior to WRC-23, the frequency band 17.3-17.7 GHz was allocated to the FSS (Earth-to-space) in Region 2, while in Region 1, the frequency band was allocated to the FSS in both the Earth-to-space and space-to-Earth directions. Under agenda item 1.19, WRC-23 considered a possible new allocation to the FSS (space-to-Earth) in Region 2 to provide greater flexibility in the use of the band by both GSO and non-GSO networks and systems, thereby ensuring a more efficient use of the spectrum. This possible new allocation would also harmonize use with Region 1, an important consideration for non-GSO FSS systems operating across regions.

64. Canada's primary objectives entering the Conference were to ensure that protection criteria and regulatory provisions reflected the results of studies, that any new FSS allocation was not limited to GSO FSS, and that there was reciprocity of protection between all three regions' planned and unplanned assignments.

Discussion

65. WRC-23 adopted a new primary allocation to the FSS (space-to-Earth) in Region 2, as well as modifications to No. 5484A to reflect this new allocation. To ensure the protection of GSO FSS and BSS incumbent services, WRC-23 also adopted modifications to No. 5.517, as well as new provisions Nos. 5.515A and 5.515B. These results were in line with Canada's objectives and ISED proposes to incorporate these new and modified provisions into the Canadian Table.

66. Prior to WRC-23, in June 2020, ISED published its Decision on the Utilization of the Bands 18.8-19.3 GHz and 28.6-29.1 GHz, and the Bands 17.3-17.7 GHz, 19.3-19.7 GHz and 29.1-29.25 GHz by the Fixed-Satellite Service, which limited use of the band 17.3-17.7 GHz in the space-to-Earth direction by the GSO FSS to low-density applications. Canadian footnote C43A incorporated these policies into the Canadian Table. Given the outcomes of the WRC-23, as discussed above, ISED proposes to suppress footnote C43A.

67. ISED notes that the frequency band 17.7-17.8 GHz has an existing allocation for the FSS in both the Earth-to-space and space-to-Earth directions, while the band 17.8-18.6 GHz has an allocation to the FSS in the space-to-Earth direction, with non-GSO FSS operations subject to Article 22.2, TABLE 22-1B to protect GSO FSS and BSS operations. To allow for more efficient use of the FSS allocation in the space-to-Earth direction across the larger 17.3-18.6 GHz frequency band, ISED proposes to extend the equivalent power flux density (EPFD) limits for the 17.3-17.7 GHz band (applicable to Region 2 only) to the 17.7-17.8 GHz frequency band, by adopting a new Canadian footnote C43B.

Non-geostationary-satellite systems in the fixed-satellite service shall not claim protection from geostationary-satellite networks in the fixed-satellite service operating in accordance with the Radio Regulations, irrespective of the dates of receipt by the Bureau of the complete coordination or notification information, as appropriate, for the non-geostationary-satellite systems in the fixed-satellite service and of the complete coordination or notification information, as appropriate, for the geostationary-satellite networks, and No. 5.43A does not apply. Non-geostationary-satellite systems in the fixed-satellite service in the above bands shall be operated in such a way that any unacceptable interference that may occur during their operation shall be rapidly eliminated. In Region 2, No. 22.2 shall continue to apply in the frequency band 17.3-17.7 GHz (WRC-232000)

ADD

5.515A In addition to the need to comply with the coordination criteria in Annex 4 to Appendix 30A, under assumed free-space propagation conditions, the power flux-density of an assignment in the fixed-satellite service (space to-Earth) of a geostationary-satellite network in the frequency band 17.3-17.7 GHz in Region 2 shall not exceed the value of −98 dB(W/(m² · 27 MHz)) at points in the geostationary-satellite orbit with geocentric orbital separation angles between 152.6° and 162.6°.

5.517 In Region 2, use of the fixed-satellite (space-to-Earth) service in the band 17.37-17.8 GHz shall not cause harmful interference to nor claim protection from assignments in the broadcasting-satellite service operating in conformity with the Radio Regulations. (WRC-2307)

SUP

C43A Assignments to stations in the broadcasting-satellite service in the frequency band 17.3-17.7 GHz may also be used for transmissions in the fixed-satellite service (space-to-Earth), provided that such transmissions do not cause more interference, or require more protection from interference, than the broadcasting-satellite service transmissions operating in conformity with the Radio Regulations. The use of these assignments by the fixed-satellite service (space-to-Earth) is limited to low density deployments of earth stations, such as gateways communicating with geostationary satellite systems that pose minimal constraints on the BSS.

ADD

C43B The use of the frequency band 17.7-17.8 GHz (space-to-Earth) by non-GSO FSS space stations is subject to the limits given in Article 22.2, TABLE 22-1B.

WRC-23 Agenda item 7: to consider possible changes, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, on advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate the rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit

Background

68. Under agenda item 7, WRC-23 considered 13 topics, identified over the course of the ITU-R study cycle, on the advance publication, coordination, notification, and recording procedures pertaining to satellite networks. The objective was to simplify and improve these procedures, and to address any deficiencies, while maintaining the guiding principles outlined in the ITU Constitution and the Radio Regulations.

69. Although modifications to advance publication, coordination, notification and recording procedures under agenda item 7 do not typically impact Article 5 and the international table of frequency allocations, the results of two of these topics at WRC-23 warrant revisions to the Canadian Table.

Topic C: Protection of geostationary satellite networks in the mobile-satellite service operating in the 7/8 GHz and 20/30 GHz bands from emissions of non-geostationary satellite systems operating in the same frequency bands and identical directions

70. Prior to the entering into force of the Radio Regulations as modified by WRC-23, there was a lack of uniformity/consistency in the regulations as to the applicable mechanism for the protection of GSO MSS networks from non-GSO FSS and MSS systems on one hand, and the application of No. 22.2 for the protection of GSO FSS networks from non-GSO FSS and MSS operating in the frequency bands 7 250-7 750 MHz (space-to-Earth), 7 900-8 025 MHz (Earth-to-space), 20.2-21.2 GHz (space-to-Earth), and 30-31 GHz (Earth-to-space) on the other. Considering the important similarities between GSO MSS and FSS networks, Topic C was established to address this inconsistency. Going into WRC-23, Canada signed-onto an Inter-American Proposal (IAP) for measures to accomplish this objective.

Topic G: Revisions to Resolution 770 (WRC-19) to allow its implementation

71. Resolution 770 (WRC-19) provides a methodology to determine conformity of non-GSO satellite systems with single-entry interference thresholds in RR Article 22 to ensure the protection of GSO FSS and BSS in the frequency bands 37.5-39.5 GHz, 39.5-42.5 GHz, 47.2-50.2 GHz and 50.4-51.4 GHz. In the period between WRC-19 and WRC-23, it was determined that corrections or clarifications to Resolution 770 (WRC-19) were required to allow for consistent application of the Resolution.

72. Canada's objective at the Conference was to modify Resolution 770 (WRC-19) to ensure that the above-mentioned methodology as well as the corrections and clarifications identified during the 2019-2023 ITU-R study period be included in an ITU-R Recommendation incorporated by reference in the Radio Regulations, instead of these elements being retained in Resolution 770.

Discussion

73. Topic C: WRC-23 adopted modifications to No. 5.461, exempting use of the 7 250-7 375 MHz and 7 900-8 025 MHz frequency bands by GSO MSS from the application of No. 9.21. No. 5.461 was also modified, and No. 5.529A was newly adopted, to expand the application of the concept of No. 22.2 to the protection of GSO MSS from non-GSO satellite networks and systems in the frequency bands with which Topic C was concerned. As decisions adopted at WRC-23 were consistent with the IAP to which Canada was a signatory, ISED proposes to incorporate these changes into the Canadian Table.

MOD

5.461 Additional allocation: the frequency bands 7 250-7 375 MHz (space-to-Earth) and 7 900-8 025 MHz (Earth-to-space) are also allocated to the mobile-satellite service on a primary basis, subject to agreement obtained under No. 9.21., with the exception that No. 9.21 shall not apply to the geostationary-satellite networks in the mobile-satellite service for which complete coordination information is received by the Bureau as of January 1, 2025 with respect to non-geostationary-satellite systems for which complete coordination or notification information, according to the case, is received by the Bureau as of January 1, 2025. Non-geostationary-satellite systems for which complete coordination or notification information, according to the case, is received by the Bureau as of January 1, 2025 shall not cause unacceptable interference to and shall not claim protection from geostationary-satellite networks in the mobile-satellite service operating in accordance with these Regulations. No. 5.43A does not apply. (WRC-23)

ADD

5.529A In the frequency bands 20.2-21.2 GHz and 30-31 GHz, non-geostationary-satellite systems for which complete coordination or notification information, according to the case, is received by the Bureau as of January 1, 2025 shall not cause unacceptable interference to and shall not claim protection from geostationary-satellite networks in the mobile-satellite service operating in accordance with these Regulations. No. 5.43A does not apply. (WRC-23)

74. Topic G: WRC-23 approved modifications to Resolution 770 (WRC-19) based on the IAP signed by Canada. While No. 5.550C, which makes reference to Resolution 770 (WRC-19), was not modified to incorporate an updated reference to that Resolution, a note was added by the Secretariat to the effect that Resolution 770 has been revised by WRC-23 and as such the previous version of that Resolution is no longer in force. ISED proposes to incorporate these changes into the Canadian Table.

MOD

5.550C The use of the frequency bands 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to‑-‑Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space) by a non-geostationary‑-‑satellite system in the fixed-satellite service is subject to the application of the provisions of No. 9.12 for coordination with other non-geostationary-satellite systems in the fixed-satellite service but not with non-geostationary-satellite systems in other services. Resolution 770 (Rev. WRC-19)* shall also apply, and No. 22.2 shall continue to apply. (WRC‑19)

* Note by the Secretariat: This Resolution was revised by WRC-23.

WRC-23 Agenda Item 9: to consider and approve the Report of the Director of the Radiocommunication Bureau in accordance with Article 7 of the ITU Convention;

9.1b: Review the amateur service and the amateur-satellite service allocations in the frequency band 1 240 - 1 300 MHz to determine if additional measures are required to ensure protection of the radionavigation-satellite service (space-to-Earth) operating in the same band in accordance with Resolution 774 (WRC-19)

Background

75. The frequency band 1 240–1 300 MHz is allocated worldwide to the radionavigation-satellite service (RNSS) in the space-to-Earth direction on a primary basis, and to the amateur service on a secondary basis. It is used for a range of amateur service applications. The amateur-satellite service (Earth-to-space) may operate in the frequency band 1 260-1 270 MHz under No. 5.282.

76. Prior to WRC-19, two Administrations observed cases of harmful interference caused by emissions from stations in the amateur service into radionavigation-satellite service (RNSS) (space-to-Earth) receivers Those Administrations documented and reported the harmful interference, and the sources of the interference were identified and resolved by the Administrations concerned. Nevertheless, the number of similar interference cases could potentially increase as RNSS receivers become more widespread. Resolution 774 (WRC-19) called on the ITU-R to study possible technical and operational measures to protect RNSS (space-to-Earth) from the amateur and amateur-satellite services, without considering the removal of these amateur and amateur-satellite service allocations, and WRC-23 considered the issue under agenda item 9.1b.

77. Canada's objective for this issue was to contribute to discussions on measures to protect RNSS (space-to-Earth), while ensuring that the allocation of amateur service in the 1 240- 1 300 MHz frequency band were not unduly constrained by measure to protect the RNSS.

Discussion

78. WRC-23 adopted No. 5.332A, referencing Recommendation ITU-R M.2164, which provides guidance to administrations in the case of a report of harmful interference caused by a station of the amateur or amateur-satellite services to the radionavigation-satellite service (RNSS) (space-to-Earth). This result achieves Canada's objectives, and ISED is therefore proposing to incorporate this provision into the Canadian Table.

ADD

5.332A Administrations authorizing operation of the amateur and amateur-satellite services in the frequency band 1 240-1 300 MHz, or portions thereof, shall ensure that the amateur and amateur-satellite services do not cause harmful interference to radionavigation-satellite service (space-to-Earth) receivers in accordance with No. 5.29 (see the most recent version of Recommendation ITU-R M.2164). The authorizing administration, upon receipt of a report of harmful interference caused by a station of the amateur or amateur-satellite services, shall take all necessary steps to rapidly eliminate such interference. (WRC-23)

9.1d: Protection of EESS (passive) in the frequency band 36-37 GHz from non-GSO FSS space stations

Background

79. Under agenda item 9.1d), WRC-23 considered the need for protection of EESS (passive) sensors operating in the frequency band 36-37 GHz from non-GSO FSS space stations operating in the frequency band 37.5-38 GHz.

80. Canada's objective at the Conference was to implement sufficient measures to protect EESS (passive) sensors in the band 36-37 GHz, without unduly constraining operations of non-GSO FSS space stations in the frequency band 37.5-38 GHz.

Discussion

81. WRC-23 adopted No. 5.550CA, which provides a limit to the unwanted emission equivalent isotropically radiated power (e.i.r.p.) density of certain non-GSO FSS systems operating in the 37.5-38 GHz frequency band in order to protect the EESS (passive) operating in the adjacent 36-37 GHz frequency band. The limit does not unduly impact satellite operations in the 37.5-38 GHz frequency band, while ensuring that EESS (passive) operating in the 36-37 GHz frequency band will be fully protected from future FSS low-Earth orbit (LEO) constellations. ISED is therefore proposing to incorporate this provision into the Canadian Table.

ADD

5.550CA Non-geostationary-satellite systems in the fixed-satellite service operating with an apogee altitude above 407 km and below 2 000 km in the frequency band 37.5-38 GHz shall not exceed an unwanted emission e.i.r.p. density of −21 dB(W/100 MHz) per space station for angles greater than 65.0° from nadir relative to the space station in the fixed-satellite service in the frequency band 36-37 GHz in order to protect the Earth exploration-satellite service (passive) operating in the latter frequency band. (WRC-23)

6.5 Modifications to international footnotes in the Canadian Table

WRC-23 Agenda Item 8: to consider and take appropriate action on requests from administrations to delete their country footnotes or to have their country name deleted from footnotes, if no longer required, taking into account Resolution 26 (Rev.WRC 19)

82. Resolution 26 (Rev.WRC-23) urges administrations to periodically review footnotes and to propose the deletion of their country footnotes or of their country names from footnotes, as appropriate. In exceptional cases, Resolution 26 (Rev.WRC-23) provides that proposals for new footnotes or modifications of existing footnotes can be considered if they concern corrections of obvious omissions, inconsistencies, ambiguities or editorial error. 'Resolves 2' to Resolution 26 states that the International Table should include those footnotes that have international implications for the use of radio frequency spectrum.

83. In light of the above, several international footnotes, also included in the Canadian Table, were modified at WRC-23 based upon proposals from administrations. ISED proposes to adopt the modifications to these footnotes as follows:

Other footnotes modified at WRC-23 and relevant to the Canadian Table

84. WRC-23 also modified numerous footnotes, as well as certain entries in the International Table of Article 5 to correct editorial errors, inconsistencies or outdated provisions. It also updated references to ITU-R Recommendations incorporated by reference under agenda item 2, and updated references to resolutions and recommendations reviewed under agenda item 4.

WRC-23 agenda item 9.2 addressed, among other things, difficulties or inconsistencies encountered in the application of the ITU Radio Regulations, as reported by the Director of the Radiocommunication Bureau to the Conference.

5.551H The equivalent power flux-density (epfd) produced in the frequency band 42.5-43.5 GHz by all space stations in any non-geostationary-satellite system in the fixed-satellite service (space-to-Earth), or in the broadcasting-satellite service, operating in the frequency band 42-42.5 GHz, shall not exceed the following values at the site of any radio astronomy station for more than 2% of the time:

–230 dB(W/m²) in 1 GHz and –246 dB(W/m²) in any 500 kHz of the frequency band 42.5-43.5 GHz at the site of any radio astronomy station registered as a single-dish telescope; and

–209 dB(W/m²) in any 500 kHz of the frequency band 42.5-43.5 GHz at the site of any radio astronomy station registered as a very long baseline interferometry station.

These epfd values shall be evaluated using the methodology given in Recommendation ITU-R S.1586-1 and the reference antenna pattern and the maximum gain of an antenna in the radio astronomy service given in Recommendation ITU-R RA.1631-0 and shall apply over the whole sky and for elevation angles higher than the minimum operating angle θ_min of the radiotelescope (for which a default value of 5º should be adopted in the absence of notified information).

These values shall apply at any radio astronomy station that either:

• was in operation prior to 5 July 2003 and has been notified to the Bureau before January 4, 2004; or
• was notified before the date of receipt of the complete Appendix 4 information for coordination or notification, as appropriate, for the space station to which the limits apply.

Other radio astronomy stations notified after these dates may seek an agreement with administrations that have authorized the space stations. In Region 2, Resolution 743 (WRC-03) shall apply. The limits in this footnote may be exceeded at the site of a radio astronomy station of any country whose administration so agreed. (WRC-1523)

5.564AFor the operation of fixed and land mobile service applications in frequency bands in the range 275-450 GHz:

The frequency bands 275-296 GHz, 306-313 GHz, 318-333 GHz and 356-450 GHz are identified for use by administrations for the implementation of land mobile and fixed service applications, where no specific conditions are necessary to protect Earth exploration-satellite service (passive) applications.

The frequency bands 296-306 GHz, 313-318 GHz and 333-356 GHz may only be used by fixed and land mobile service applications when specific conditions to ensure the protection of Earth exploration-satellite service (passive) applications are determined in accordance with Resolution 731 (Rev.WRC-1923).

In those portions of the frequency range 275-450 GHz where radio astronomy applications are used, specific conditions (e.g. minimum separation distances and/or avoidance angles) may be necessary to ensure protection of radio astronomy sites from land mobile and/or fixed service applications, on a case-by-case basis, in accordance with Resolution 731 (Rev.WRC-1923).

The use of the above-mentioned frequency bands by land mobile and fixed service applications does not preclude use by, and does not establish priority over, any other applications of radio services in the range of 275-450 GHz. (WRC-1923)

86. The following entries in the Canadian Table are proposed for modification to correct editorial errors, inconsistencies or outdated provisions, in line with modifications adopted to the International Table of Article 5 at WRC-23:

87. WRC-23 decided to move the reference to No. 5.208 in the frequency range 137-138 MHz from the bottom row of the table to the mobile-satellite (space-to-Earth) allocation, as No. 5.208 applies only to the MSS.

88. WRC-23 decided to move the reference to No. 5.388 in the frequency ranges 1885 – 2025 MHz and 2110 – 2200 MHz from the bottom row of the table to the mobile allocation, in line with typical practice for footnotes concerning IMT identifications. ISED is proposing to adopt the same modification to the Canadian Table, except for frequency ranges in which IMT systems can operate under multiple allocations. In these cases, such as the 2000 – 2020 MHz frequency range which is allocated to both the mobile and mobile-satellite services, the reference will be retained in the bottom row of the frequency range.

6.6 Other modifications to the Canadian Table

89. This section proposes revisions to the Canadian Table needed as a result of any editorial errors or inconsistencies identified during the review of the previous Canadian Table.

90. A number of instances were noted in which frequency ranges allocated to the same radiocommunication services were split between multiple rows of the table. To simplify and reduce its overall length, ISED proposes to merge the following frequency ranges in the next edition of the Canadian Table:

• 6525 – 6685 kHz and 6685 - 6765 kHz will be merged into a single row for 6525 – 6765 kHz
• 944 – 952 MHz and 952 – 956 MHz will be merged into a single row for 944 – 956 MHz
• 1660.5 - 1668 MHz and 1668 - 1668.4 MHz will be merged into a single row for 1660.5 - 1668.4 MHz
• 31.8 - 32 GHz and 32 GHz - 32.3 GHz will be merged into a single row for 31.8 - 32.3 GHz

91. As mentioned in section 5.3, the international table of frequency allocations lists services in alphabetical order, based on the name of each service in the French language. A number of instances were noted in which this convention is not properly observed within the Canadian Table, and ISED proposes to editorially modify the Canadian Table to address this inconsistency. The following frequency ranges will be affected by these modifications:

• 2 596 – 2 655 MHz
• 2 655 – 2 686 MHz

92. No. 5.228D indicates that the frequency bands 161.9625 - 161.9875 MHz and 162.0125 - 162.0375 MHz may continue to be used by the fixed and mobile services on a primary basis until January 1, 2025. With the end date having passed, and the frequency bands not allocated to the fixed and mobile services in Canada, ISED proposes to remove references to the No. 5.228D from the Canadian Table. However, as No. 5.228D remains in the current edition of the Radio Regulations, ISED is not proposing to suppress the footnote at this time.

93. A reference to No. 5.416 was retained in 2 500 – 2 686 MHz following the removal of allocations to the broadcasting-satellite service in that frequency range. Since No. 5.416 pertains to a service that is no longer allocated in the specified frequency range in Canada, ISED is of the view that it is not necessary and therefore proposes to suppress the footnote in the next edition of the Canadian Table.

SUP 5.416

94. In the international table of frequency allocations, the frequency range 5010 – 5030 MHz is allocated to the RNSS in both the space-to-Earth and space-to-space directions. However, in the Canadian Table, this allocation to the RNSS was inadvertently made in the Earth-to-space and space-to-space directions. ISED proposes to correct this error in the next edition of the Canadian Table.

95. ISED proposes to permanently remove the following footnotes, which are indicated as suppressed in the Canadian Table (Edition 2022), from the new 2026 Edition:

SUP 5.396 (SUP-WRC-19)

SUP 5.562F (SUP-WRC-19)

SUP 5.562G (SUP-WRC-19)

96. One WRC-23 agenda item resulted in a change to a definition set out in Section 1 of the Canadian Table.

Agenda Item 9 - to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the ITU Convention:

Agenda Item 9.1 - on the activities of the Radiocommunication Sector since WRC-19

97. WRC-23 adopted revisions to Resolution 655 (Rev.WRC-23). As a result, there was a modification to the definition of Coordinated Universal Time (UTC) contained in Article 1 of the Radio Regulations, to reflect the revised Resolution 655 (Rev.WRC-23). ISED proposes to adopt the revised definition in Section 1 of the Canadian Table as follows:

Coordinated Universal Time (UTC): Time scale, based on the second (SI), as described in Resolution 655 (WRC-1523).

98. Seven WRC-23 agenda items resulted in no change, or no change to Region 2 in Article 5 of the Radio Regulations, and therefore have no impact on the Canadian Table:

WRC-23, Agenda item 1.1: (WRC-23, Agenda item 1.1): to consider, based on the results of ITU-R studies, possible measures to address, in the frequency band 4 800-4 990 MHz, protection of stations of the aeronautical and maritime mobile services located in international airspace and waters from other stations located within national territories, and to review the power flux-density criteria in No. 5.441B in accordance with Resolution 223 (Rev. WRC-19)

99. WRC-23 adopted changes to Resolution 223 (Rev. WRC-23) to reflect the identification of additional frequency bands for IMT. ISED does not currently plan to implement these additional frequency bands or the frequency band 4 800-4 990 MHz in Canada, and is proposing to retain existing references to Resolution 223 (Rev. WRC-23) in the Canadian Table.

WRC-23, Agenda item 1.3: to consider primary allocation of the frequency band 3 600 3 800 MHz to the mobile service in Region 1 and take appropriate regulatory actions, in accordance with Resolution 246 (WRC-19)

100. WRC-23 decided to make a primary allocation to the mobile, except aeronautical mobile, service in the 3 600-3 800 MHz frequency band, which includes technical restrictions at the border of a neighbouring country. Several footnotes were added to this allocation to identify the frequency range, or parts thereof, for IMT in many countries of Africa. This allocation for Region 1 aligns with the type of use in Region 2 and is a positive result for equipment harmonization. Since these modifications pertain only to Region 1, no modifications to the Canadian Table are proposed.

WRC-23, Agenda item 1.5: to review the spectrum use and spectrum needs of existing services in the frequency band 470-960 MHz in Region 1 and consider possible regulatory actions in the frequency band 470-694 MHz in Region 1 on the basis of the review, in accordance with Resolution 235 (WRC-15)

101. WRC-23 adopted three new provisions, and modified three others, pertaining to Region 1. Consequential changes were made to Resolution 224 (Rev.WRC-23) and subsequently to No. 5.317A. These changes are addressed in Section 6.5 of this document.

WRC-23, Agenda item 1.6: to consider, in accordance with Resolution 772 (WRC-19), regulatory provisions to facilitate radiocommunications for sub-orbital vehicles

102. WRC-23 decided on no change to the Radio Regulations. As a result, no modifications to the Canadian Table are proposed.

WRC-23, Agenda item 1.8: to consider, on the basis of ITU-R studies in accordance with Resolution 171 (WRC-19), appropriate regulatory actions, with a view to reviewing and, if necessary, revising Resolution 155 (Rev.WRC-19) and No. 5.484B to accommodate the use of fixed-satellite service networks by control and non-payload communications of unmanned aircraft systems

103. WRC-23 decided on no change to the Radio Regulations. As a result, no modifications to the Canadian Table are proposed.

WRC-23, Agenda item 1.9: to review Appendix 27 of the Radio Regulations and consider appropriate regulatory actions and updates based on ITU R studies, in order to accommodate digital technologies for commercial aviation safety-of-life applications in existing HF bands allocated to the aeronautical mobile (R) service and ensure coexistence of current HF systems alongside modernized HF systems, in accordance with Resolution 429 (WRC-19)

104. While WRC-23 adopted modifications to Appendix 27 of the Radio Regulations under this agenda item, no modifications pertaining Article 5 were adopted. As a result, no modifications to the Canadian Table are proposed.

WRC-23, Agenda Item 1.10: to conduct studies on spectrum needs, coexistence with radiocommunication services and regulatory measures for possible new allocations for the aeronautical mobile service for the use of non-safety aeronautical mobile applications, in accordance with Resolution 430 (WRC-19)

105. WRC-23 adopted new allocations to the aeronautical mobile service for the use of non-safety applications in Region 1 and Region 3, alongside associated footnotes for the protection certain existing services. As there were no change to the Radio Regulations in Region 2, no modifications to the Canadian Table are proposed.

WRC-23, Agenda Item 1.18: to consider studies relating to spectrum needs and potential new allocations to the mobile-satellite service for future development of narrowband mobile-satellite systems, in accordance with Resolution 248 (WRC-19);

106. WRC-23 decided on no change to the Radio Regulations. As a result, no modifications to the Canadian Table are proposed.
