Proposed Revisions to the Canadian Table of Frequency Allocations (2009 Edition)
(PDF, 623 KB, 70 pages)

1. Intent

This consultation paper, announced in Canada Gazette Notice DGTP-003-09, reviews the Canadian Table of Frequency Allocations (the Canadian Table) and makes proposals for its revision, taking into account the results of the 2007 World Radiocommunication Conference (WRC-07) and domestic requirements. The Canadian Tablewas last modified in May 2005, to incorporate the results of WRC-03 and previous WRCs, and implement domestic policies. Subsequent changes have been made since then to reflect changes in domestic policies.

The accompanying Canada Gazette notice invites public comments on these proposals. As well, Industry Canada welcomes any input to ensure the completeness of the Canadian Table.

2. Background

The International Telecommunication Union (ITU) adopts an International Table of Frequency Allocations (the International Table) as part of its Radio Regulations. This International Table allocates spectrum to various combinations of radio services and may include conditions for the use of the spectrum. Examples of the internationally defined services include broadcasting, mobile services and fixed-satellite service. The International Table is revised, along with other parts of the international Regulations, at meetings of the ITU World Radiocommunication Conferences (WRC), which are held on a periodic basis.

The Canadian Table is derived from the International Table adopted by the ITU. The Canadian Table contains those radio services required to meet Canadian needs, among those allocated by the ITU, including the applicable international footnotes. This domestic table also specifies, by allocation and Canadian footnote, any additional provisions for use of those services in Canada.

Industry Canada revises the Canadian Table on a periodic basis, normally following a WRC. WRC-07, which met in October/November 2007, in Geneva, Switzerland, adopted a number of changes to the frequency allocations in the International Table. The Conference dealt with issues concerning amateur, mobile, radiolocation, navigation, science, broadcasting-satellite, mobile-satellite, fixed and the fixed-satellite services. The resulting changes to the International Table necessitate consideration of several domestic issues. Also, domestic requirements for other changes to the Canadian Table have emerged, and will be addressed as well. The remainder of this document discusses these issues and makes proposals for revisions to the Canadian Table.

3. Process

The accompanying Canada Gazette notice (DGTP-003-09) invites public comment on the proposals contained in this consultation paper. Following the review of comments received, the allocation decisions will be promulgated by the issuance of a revised Canadian Table.

Section A: Mobile, Aeronautical Mobile, Radiolocation and Radiolocation Services

A1 (AI 1.3) – Radiolocation Service in the 9 000 MHz Band

Background (A)

Upgrade of the Radiolocation Service in the Bands 9 000-9 200 MHz and 9 300-9 500 MHz

As identified in Resolution 747 (WRC-03), there is a need to provide contiguous primary spectrum around the 9 000 MHz band in order for existing and planned radiolocation systems to satisfy their required missions. Changes in technology and emerging requirements for increased image resolution and increased range accuracy necessitate wider contiguous emission bandwidths. Therefore, there is a need to upgrade the status of frequency allocations to the radiolocation service in the frequency range 9 000-9 200 MHz and 9 300-9 500 MHz.

The bands 9 000-9 200 MHz and 9 300-9 500 MHz are allocated on a primary basis to aeronautical radionavigation and radionavigation respectively. Radio Regulation No. 4.10 recognizes radionavigation as a safety service. The radiolocation services and the radionavigation service have demonstrated compatible operations over many years through the use of similar system characteristics such as low-duty cycle emissions, scanning beams and interference reduction techniques. For example, past operational experience in the band 2 900-3 100 MHz as found in Report ITU-R M.2032, Tests illustrating the compatibility between maritime radionavigation radars and emissions from radiolocation radars in the band 2 900-3 100 MHz, confirms that it is possible to mitigate interference from radiolocation radars to maritime radionavigation radars in the band.

Some completed studies within ITU-R WP 8B* characterize the technical performance and protection criteria of radiolocation and radionavigation systems that ensure compatible operations in the bands 9 000-9 200 MHz and 9 300-9 500 MHz. Recommendation ITU-R M.1313 contains the technical characteristics and protection criteria for maritime radars in the band 9 300-9 500 MHz, and Recommendation ITU-R M.1372 identifies interference reduction techniques that enhance compatibility among radar systems.

The completed ITU-R studies on radionavigation radars and emissions from radiolocation radars in the band 9 000-9 500 MHz illustrate compatibility between the two services in this band. These studies indicate that typical radionavigation radars can suppress emissions from other radars, even when the radar receivers operate with very high interference-to-noise (I/N) ratios if the unwanted pulsed waveform is asynchronous and has a low effective duty cycle. These study results support the successful historical sharing experience between the services in the 9 000-9 500 MHz band. Therefore, a primary allocation for radiolocation can be added to the 9 000-9 200 and 9 300-9 500 MHz bands.

ADD MOD 5.476A See Section A1-B.

Discussion

Given the potential allocation to other services in the upper band 9 300-9 500 MHz, and because of similarity of services in the two bands, the agenda item focused on the upgrade of radiolocation from the secondary to the primary status. Radiolocation systems in these bands have been operating compatibly with the radionavigation service, allocated on a primary basis as it is a safety of life service.

Canada joined the CITEL Inter-American Proposal (IAP) on this agenda item, which supported the upgrade to a primary status on condition that a new footnote be created to maintain the relative status between radiolocation and radionavigation, recognizing that radionavigation is used for safety of life.

Because the ITU-R studies and extensive experience had shown compatibility, there was opposition to establishing super-primary status. The agreed upon solution was to refer to systems of the service. This way, one service would not have a higher status, but specific systems could claim extra protection.

In the case of the band 9 000-9 200 MHz, systems that can be deployed are already limited to those listed in No. 5.337. The new footnotes also conveyed protection to the maritime radionavigation systems operating in this band under a primary allocation in specific countries. Consequently, new footnotes were created that provided the required protection for the specific systems under the radionavigation service.

Regarding the modification to No. 5.475, the priority of the meteorological ground-based radars is included in added provision No. 5.473B for housekeeping purposes.

Background (B)

200 MHz Extension of the Primary EESS (Active) and SRS (Active) Allocations

The band 9 500-9 800 MHz is allocated on a primary basis to the Earth exploration-satellite (EESS) (active), space research (SRS) (active), radiolocation and radionavigation services. In order to satisfy global environmental monitoring requirements for increased resolution, the EESS (active) and the SRS (active) allocations require an increase of 200 MHz.

The ITU-R studied the compatibility between the EESS (active) and the existing services in the two bands identified by Resolution 747 (WRC-03) for consideration as extension bands.
 
Results of ITU-R tests and measurements indicate that representative radiolocation and radionavigation radars do not suffer any performance degradation due to any of the representative EESS (active) waveforms. These various ITU-R compatibility studies combined with tests and measurements indicate that sharing is feasible in the additional 200 MHz of spectrum between the EESS (active) and existing services in either the 9 300-9 500 MHz band or the 9 800-10 000 MHz band. In addition, these studies demonstrate that narrow band (less than 300 MHz) synthetic aperture radars (SAR s) present higher interference potential compared to wide band (300 MHz or greater) SAR s extending over the whole 9 300-9 800 MHz band. With respect to sharing between the EESS (active) and the fixed service, ITU-R studies have shown that interference from a distribution of FS transmitters operating in the 9 800-10 000 MHz band did not exceed the interference threshold of a spaceborne SAR.

Recognizing further that narrow bandwidth (less than 300 MHz) SAR can operate in the existing frequency band (9 500-9 800 MHz) and that the requested extension is only justified for SAR systems requiring more than 300 MHz bandwidth, a limitation of such 200 MHz extension to these wideband (300 MHz or greater) SAR systems could limit the risk of interference to meteorological radars while responding to the need for 200 MHz EESS extension.

Given that the SRS (active) systems operate in the vicinity of planets and celestial bodies other than the Earth or as experimental platforms for future EESS (active) systems, SRS (active) systems were not studied for compatibility with any Earth-based systems. Another possible use of the SRS (active) is as an experimental platform for a future EESS (active) system. However, in this case, the SRS (active) system and the EESS (active) system would be essentially the same. With respect to other types of EESS (active) systems other than SAR s, it should be noted that precipitation radars and cloud profile radars cannot operate in this frequency range due to the physical characteristics of their intended applications. Altimeters, which are wideband EESS (active) systems operating at relatively low-power levels, have been shown to not cause interference to radiodetermination systems in the 9 500-9 800 MHz band. Results for any extension band should be analogous.

Discussion

This issue addressed the extension of the primary allocations to EESS (active) and SRS (active) for a total of 500 MHz of contiguous spectrum, for systems that could not be accommodated within the 300 MHz in 9 500-9 800 MHz because of an operating bandwidth greater than 300 MHz. The radionavigation and radiolocation services will continue to be protected from EESS (active) and SRS (active) systems.

The extension of these allocations up to 200 MHz, in the downward direction, was not controversial. However, the European Conference of Postal and Telecommunications Administrations (CEPT) also wanted to extend the allocation by another 100 MHz from 9 800-9 900 MHz for the operation of a 600 MHz bandwidth satellite system, for better resolution. This was considered outside the scope of the agenda item and the WRC refused to address the issue until the very last days of the Conference. As a last-minute compromise, EESS and SRS were granted a secondary allocation that must also protect the status of the FS even though the FS is allocated a secondary status. This addition was supported by Canadian stakeholders who can make use of the data provided by this additional extension to EESS and SRS, while not harming the other services to which the band is allocated.


*As a result of ITU-R re-structuring, ITU-R WP 8B is now known as ITU-R WP 5B

A2 (AI 1.4) – Spectrum for Advanced Mobile Systems (IMT-2000 and beyond)

Background

International Mobile Telecommunications (IMT) systems are mobile systems that provide access to a wide range of telecommunication services, including advanced mobile services, supported by mobile and fixed networks, which are increasingly packet-based.

In Resolution 228 (WRC-2003), the ITU-R was asked to report, in time for WRC-07, on the results of studies on the spectrum requirements and potential frequency ranges suitable for the future development of IMT-2000 and systems beyond IMT-2000 (IMT-Advanced), taking into account the:

  • evolving user needs, including the growth in demand for IMT-2000 services;
  • evolution of IMT-2000 and pre IMT-2000 systems through advances in technology;
  • bands currently identified for IMT-2000;
  • time frame in which spectrum would be needed;
  • period for migration from existing to future systems; and
  • extensive use of frequencies below those identified for IMT-2000 in No. 5.317A.

Resolution ITU-R 56 provides the new name for Systems Beyond IMT-2000, IMT-Advanced, and resolves that "IMT" is the root name that encompasses both IMT-2000 and IMT-Advanced systems. When considering the naming of IMT systems, one must consider the Radio Regulations and regulatory clarity. Systems that meet the regulatory criteria in the frequency band should not be limited in their evolution and there is no precedence for limiting an allocation in the Radio Regulations to a specific technology or generation of technology. Therefore, WRC-07 decided to identify spectrum generically for IMT.

The objectives of identifying spectrum for use by IMT are to encourage global harmonization and to provide guidance to manufacturers so that they can develop equipment for global roaming at minimum cost. In order to maximize the benefit of this newly available spectrum, it is important to establish an international regulatory framework that allows adequate time for regulators, manufacturers and operators to prepare for the introduction of new services.

In addition to bands already identified for IMT-2000, the following bands were considered for the terrestrial component of IMT-2000 and IMT-Advanced: 410-430 MHz, 450-470 MHz, 470-806/862 MHz, 2.3-2.4 GHz, 2.7-2.9 GHz, 3.4-4.2 GHz and 4.4-4.99 GHz. In all of these bands, administrations have implemented various systems and services, as listed in Report ITU-R M.2079, so that these bands are not currently available for the worldwide or Regional deployment of IMT-2000 and IMT-Advanced.

Regulatory and technical studies were carried out to assess the advantages and disadvantages of identifying specific frequency bands for IMT-2000 and IMT-Advanced. These studies addressed sharing and compatibility considerations with services that already have allocations in candidate spectrum for IMT identification, taking into account the needs of other services.

As a result, the following bands were identified for IMT at WRC-07: 450-470 MHz, parts of 698-862 MHz (varies Regionally), 2 300-2 400 MHz and 3 400-3 600 MHz in Regions 1 and 3.

With regard to the satellite component of IMT-2000 and IMT-Advanced, studies were undertaken to assess the spectrum requirements for the period 2010 to 2020, which identified a requirement for additional spectrum. Candidate frequency bands for the satellite component were proposed for identification in the ranges 1 518-1 525 MHz and 1 668-1 675 MHz, recognizing the difficulties of using the band 1 668-1 675 MHz for such a purpose (see No. 5.380A and Resolution 744 (Rev. WRC-07)).

450-470 MHz

WRC-07 identified the band 450-470 MHz for global IMT through new international footnote No. 5.286AA. In addition, WRC-07 adopted modifications to footnote Nos 5.286D and 5.286E under Agenda Item 1.1.

Canada and the United States submitted a declaration that states:

"The United States of America and Canada state that, in application of the Final Acts of the World Radiocommunication Conference (Geneva, 2007) pertaining to the use of the 450-470 MHz band, they intend to make use of applications in the mobile service and fixed service, including public safety networks, in the 450-470 MHz band, as appropriate, which will preclude its use for terrestrial International Mobile Telecommunications (IMT)."

ADD Cxx (CAN-09) In Canada, the band 450-470 MHz is not generally available for use by broadband systems (e.g., IMT) due to the extensive use by conventional and trunked mobile radio systems.

Discussion

The Department believes that the proposed changes to the Canadian Table will reflect the identification of IMT in the band 450-470 MHz internationally. In Canada, however, the band is not generally available for IMT systems due to its extensive use by existing systems.

698-806 MHz

The use of the 700 MHz band in Canada will be the subject of a forthcoming consultation that will address, among other issues, proposals for modifications to the Canadian Table, including the adoption of WRC-07 decisions related to the 700 MHz band.

IMT Satellite Component Bands

WRC-07 identified the bands 1 518-1 525 MHz and 1 668-1 675 MHz for use by the satellite component of IMT. Canada's position on this issue was neutral.

Discussion

The Department believes that the proposed changes to the Canadian Table will reflect the identification of the bands for the satellite component of IMT. The modification to footnote No. 5.351A identifies new bands for use by the satellite component of IMT through Resolutions 212 and 225. Footnote No. 5.348C is no longer necessary.

2 300-2 400 MHz

WRC-07 globally identified the band 2 300-2 400 MHz for use by IMT through changes to international footnote No. 5.384A.

Canada and the United States submitted a declaration that states:

"The United States of America and Canada refer to footnote No. 5.394 of Article 5 of the Radio Regulations concerning the use of the 2 300-2 390 MHz band in the United States and the 2 300-2 400 MHz band in Canada and state that, in application of the Final Acts of the World Radiocommunication Conference (Geneva, 2007) in those bands, the aeronautical mobile service for telemetry has priority over other uses by the mobile services. Furthermore, in conformity with additional allocations specified in footnote No. 5.393 of Article 5 of the Radio Regulations in the 2 310-2 360 MHz band, the United States of America and Canada state that, in application of the Final Acts of the World Radiocommunication Conference (Geneva, 2007) in the band 2 310-2 360 MHz, they intend to use parts of this band for the broadcasting-satellite service (sound) and complementary terrestrial sound broadcasting service, which may preclude its use for terrestrial International Mobile Telecommunications (IMT)."

Discussion

The Department believes that the proposed changes to the Canadian Table will reflect the international identification of the band 2 300-2 400 MHz for IMT. The new Canadian footnote shows which portions of the band 2 300-2 400 MHz may be available for IMT in Canada.

3 400-4 200 MHz

Although many countries in other Regions signed onto footnotes identifying the band 3 400-3 600 MHz for IMT, Canada and Region 2 did not identify this band. Some other administrations in our Region did opt to upgrade their mobile allocation to primary in the band 3 400-3 500 MHz through a footnote.

A3 (AI 1.5) – Spectrum Requirements for Aeronautical Telecommand and High Bit-Rate Aeronautical Telemetry

Background

This agenda item addressed a growing demand for spectrum allocated for aeronautical telemetry and associated telecommand. There was an increasingly significant shortfall in spectrum necessary to conduct aeronautical telemetry. The shortfall was exacerbated by the loss of telemetry spectrum diverted to other applications and services. Without access to additional spectrum, aeronautical development would be subject to escalating delays and costs, and the growth of the aerospace industry would be impaired (including equipment manufacturers, civilian programs and test ranges, as well as airlines).

Aeronautical mobile telemetry (AMT) is an application within the aeronautical mobile service. The new allocations enabling aeronautical mobile telemetry applications include the band 4400-4940 MHz through the new footnote 5.440A, the band 4825-4935 MHz through Mod 5.442, the band 5091-5150 MHz through the new footnote 5.444B and the band 5925-6700 MHz through the new footnote 5.457C. These aeronautical mobile telemetry applications will only be for transmission of telemetry information for flight test purposes in the air-to-ground direction inasmuch as telecommand functions (i.e. ground-to-air transmissions) can be accommodated in existing bands. Consequently, in these bands, AMT in the aeronautical mobile service is not considered an application of a safety service as defined in RR No. 1.59. These international footnotes are instrumental in the establishment of spectrum sharing conditions and Canada-US cross-border coordination arrangements. The department plans to hold public consultations in the near future to develop spectrum utilization policies to address the spectrum requirements of the aeronautical community and AMT in particular.

Hence, AMT applications in new spectrum will not require the level of protection associated with operations in existing telemetry bands. However, the new AMT application may share spectrum with other services such as fixed and fixed satellite services. The World Radio Conference has considered ITU-R studies that have determined conditions under which AMT for flight test purposes can be implemented without adversely affecting the operation of existing systems and allocated services.

Discussion

The Department believes that the proposed changes to the Canadian Table will help address the needs for AMT for flight test purposes in Canada while providing protection to the existing services and systems. It will also provide adequate regulatory mechanisms to ensure the protection of Canadian systems from AMT for flight test purposes to be deployed by the United States in border areas in the 4/6 GHz band.

A4 (AI 1.6) - Aeronautical Mobile (R) Service in Bands 108– MHz - 6 GHz and Modernization of Civil Aviation Systems

Background

Resolution 414 (WRC-03)

Existing AM(R)S bands are nearing saturation in high-traffic areas. In addition, new applications and concepts in air traffic management put further pressure on existing AM(R)S bands that do not conform to the definition of aeronautical radionavigation in the Radio Regulations.

ITU-R Working Party 8B* (WP 8B) and the International Civil Aviation Organization (ICAO) developed a draft operational concept, as well as technology selection criteria and procedures for new aviation technology requiring two distinct categories of AM(R)S spectrum. The first category for surface applications at airports could support high data throughput over moderate transmission distances. There is a high degree of reuse of this spectrum. The second category for bidirectional air-to-ground applications could support a moderate data throughput over longer propagation distances out to radio line-of-sight. These applications require a number of distinct channels to allow for sector-to-sector assignments.

WRC-07 addressed these issues under Agenda Item 1.6 and Resolution 414 (WRC-03). Consequential modifications to No. 5.444A were also considered.

  • aeronautical security transmissions. Such use shall be in accordance with Resolution 419 (WRC-07)(WRC-07)

Discussion

The Department believes that the proposed changes to the Canadian Table will satisfy the needs for Aeronautical Mobile (En route) Service (AM(R)S) growth and requirements while providing protection to the existing services and systems. The Department also believes that the modification of the status of microwave landing systems (MLS) in the band 5 091-5 150 MHz is acceptable to permit the introduction of the new AM(R)S systems, as the protection of future MLS deployment has been considered in the applicable Resolutions.

A5 (AI 1.9) – to review the technical, operational and regulatory provisions applicable to the use of the band 2 500-2 690 MHz by space services in order to facilitate sharing with current and future terrestrial services without placing undue constraint on the services to which the band is allocated.

The use of the 2 500 MHz band in Canada will be the subject of a forthcoming consultation that will address, among other issues, proposals for modifications to the Canadian Table, including the adoption of WRC-07 decisions related to the 2 500 MHz band.

B1 (AI 1.2) – Allocations and Regulatory Issues related to the Earth Exploratory Space Service (passive), Space Research Service (passive) and Meteorological Satellite (MetSat) Service

B1 - Part (A) Expansion of the MetSat Allocation by 100 MHz Around 18 GHz

Background

Remote sensing of the Earth from space provides the meteorological community with the critical data required to predict the future state of the environment. With the rapid advances in remote sensing technologies, communication systems, computing capabilities and the increased knowledge of the physical processes involved in the development of weather systems, the meteorological community will take advantage of higher resolution data to observe and predict the motion, development and decay of short-term events, such as severe thunderstorms, for appropriate warnings to the general public.

A primary allocation to the geostationary-satellite orbit (GSO) MetSat (space-to-Earth) service already exists in the band 18.1-18.3 GHz based on RRNo. 5.519. However, it is recognized that the bandwidth of the existing allocation is insufficient to support the required data rates. The next generation GSO MetSat systems are expected to have bandwidth requirements up to 300 MHz.

While sharing between GSO MetSat systems and FSS systems is generally feasible, operating MetSat systems below 18.3 GHz would avoid several potential difficulties with High Density Fixed-Satellite Service (HDFSS). Therefore, Canada supported an expansion of the current allocation by an additional 100 MHz below 18.1 GHz to satisfy the high data rate requirement of MetSat.

Their use is limited to geostationary satellites. (WRC-07)

Discussion

The Department believes that the proposed changes to the Canadian Table will satisfy the following needs:

  • the meteorological community will be able to meet its future operational requirement;
  • the fixed service will be protected given that the regulatory measures that currently apply in the existing MetSat allocation in the band 18.1-18.3 GHz will also apply in the expansion band; and
  • the development of HDFSS operating in the band above 18.3 GHz will not be constrained in Region 2, as the MetSat will be operating in the band 18.0-18.3 GHz.

B1 - Part (B) Revision of the Sharing Criteria between Earth Exploration Satellite Service (EESS) (passive) and Fixed and Mobile Services (FS and MS) in the Band 10.60-10.68 GHz

Background

The band 10.6-10.68 GHz is allocated to the passive services on a primary basis, including the EESS (passive), the radio astronomy service (RAS) and the SRS (passive). This band is of prime interest to measure rain, snow, sea state and ocean wind. The retrieved data is part of a set of measurements performed in five interrelated frequency bands (around 6, 10, 18, 24 and 36 GHz). This data is used by and exchanged between meteorological organizations in all Regions.

The 10.6-10.68 GHz band is also allocated to the FS on a primary basis. It is used by the FS for point-to-point and point-to-multipoint systems.

Currently, No. 5.482 limits the equivalent isotropically radiated power (e.i.r.p.) of FS and MS stations in this band to 40 dBW and the transmitter power to –3 dBW, except in the 26 countries listed in the footnote. However, it has been shown that this provision is not sufficient to ensure the protection of the EESS (passive) in the band 10.6-10.68 GHz.

Discussion

The Department is of the view that the proposed modifications will provide a good balance between the operational requirements of the passive and active systems, as appropriate protections will be afforded to future EESS (passive) systems without imposing undue constraints to the development of fixed systems.

B1 – Part (C) Development of Sharing Criteria between Earth Exploration-Satellite Service (EESS) (passive) and Fixed and Mobile Services (FS and MS) in the Band 36-37 GHz

Background

The band 36-37 GHz is allocated on a primary basis to the EESS (passive), SRS (passive), FS and MS. The data gathered by EESS (passive) and SRS (passive) systems operating in the band 36-37 GHz contributes to the estimate of total vapour, total cloud liquid water, sea surface wind speed, sea surface temperature, sea ice extent, snow depth and soil moisture content. These parameters are derived from measurements near 7, 10.7, 18.7, 23.8, 50.3, 52.8 and 89 GHz combined with measurements in the 36-37 GHz band.

Without the appropriate regulatory measures, the FS and MS systems could potentially cause interference to the passive services, and the collection of vital scientific information by EESS (passive) systems could be compromised.

Discussion

The Department is of the view that the mandatory power limits imposed on stations of future fixed and mobile systems, as well as the limitation on some operational characteristics of EESS (passive) systems, will facilitate sharing between future passive and active systems in the band 36-37 GHz without unduly constraining their development.

B2 (AI 1.20) - Protection of Earth Exploratory Space Services (passive) from Unwanted Emissions of Active Services

Background

The compatibility between the EESS (passive) and active services has been discussed since WRC-95. Based on the experience gained from the four previous conferences, WRC-07 was requested to consider the results of the ITU-R compatibility analysis, using band pairs identified in Resolution 738 and the associated proposals for regulatory measures regarding the protection of EESS (passive) from unwanted emissions of active service stations.

In order to address this issue, and taking into consideration the impacts on both the active and the passive services involved, WRC-07 adopted two regulatory measures:

  • impose a limit on the power level of unwanted emissions from the active stations; and
  • recommend compliance with a maximum power level of unwanted emissions from active stations.

Discussion

After extensive discussion at WRC-07, Resolution 750 (WRC-07) was adopted in an effort to balance the interests of both the EESS (passive) and the active services and to ensure compatibility between these services in some specified band pairs. The Department believes that, with these regulatory measures, collection of vital scientific information through EESS (passive) systems will be protected without putting undue constraint on the deployment and the development of active services in the adjacent bands.

B3 (AI 1.21) - Compatibility between the Radio Astronomy Service and Active Space Services

Background

WRC-03 adopted Resolution 739, which defines a consultation process for select radio astronomy/active space service band pairs to assist administrations in reaching mutually acceptable solutions when unwanted emissions from space services exceed specified levels in certain radio astronomy bands. WRC-03 also adopted Resolution 740 to expand the consultation process to some other band pairs, taking into consideration the results of ITU-R studies.

After extensive discussions, WRC-07 agreed to expand the consultation process to all of the band pairs for which studies have been concluded within the ITU-R.

C1 (AI 1.7) - Sharing between Mobile-Satellite Service (MSS) and Space Research Service (SRS) (1 668-1 668.4 MHz) and Mobile Service (1 668.4-1 675 MHz)

Background

Issue A:

The band 1 668-1 668.4 MHz is allocated to the space research (passive) service (SRS (passive)) and the MSS (Earth-to-space).

WRC-07 was requested to take appropriate measures to ensure the protection of space research (passive) space stations from harmful interference from mobile earth stations in the band 1 668-1 668.4 MHz, taking care to avoid undue constraints on either service's stations.

WRC-07 adopted conditions to trigger the coordination procedure between MSS and SRS (passive) systems.

Issue B:

The band 1 668.4-1 675 MHz is allocated to the fixed and mobile services. Since WRC-03, the band 1 670-1 675 MHz has also been allocated to the MSS (Earth-to-space). WRC-07 was requested to address the sharing issue between the mobile-satellite service and the fixed and mobile services.

The Conference decided to limit the use of the mobile service allocation to transportable radio-relay systems and recommended compliance with specific power levels for stations in these systems, except in two countries, Canada and the United States.

Discussion

During WRC-07 discussions, Canada did not have any preference on the approach to be considered to ensure the protection of SRS (passive) under Issue A. Concerning Issue B, the objective was to guarantee a complete access to the band 1 670-1 675 MHz for mobile and fixed service systems in Canada, noting the non-practicability of an MSS deployment in Canada. This has been achieved through modification of footnote No. 5.379D and Resolution 744 (Rev. WRC-07).

C2 (AI 1.17) - Sharing Between Fixed Satellite Service (FSS) and Mobile-Satellite Service (MSS) Feeder Links in the 1.4 GHz Band and Other Services

Background

WRC-03 allocated the bands 1 390-1 392 MHz and 1 430-1 432 MHz to the FSS on a secondary basis limited to feeder links of non-GSO satellite systems in the MSS operating below 1 GHz. WRC-03 also recognized the need to delay the use of these bands until the completion of the studies requested by Resolution 745 (WRC-03) and their consideration by WRC-07.

On the basis of ITU-R studies, WRC-07 unanimously decided to suppress the secondary FSS allocation in the bands 1 390-1 392 MHz and 1 430-1 432 MHz. WRC-07 took into consideration the incompatibility between the protection requirements of incumbent services and services operating in the adjacent bands, as well as the operational requirements of FSS stations.

These allocations are limited to use for feeder links for non-geostationary-satellite networks in the mobile-satellite service with service links below 1 GHz, and Resolution 745 (WRC-03) applies.

Discussion

At WRC-07, there was a unanimous agreement among administrations to remove the secondary allocation to FSS in the bands 1 390-1 392 and 1 430-1 432 MHz. In Canada, the implementation of this WRC-07 decision will help to avoid an increase in interference as a result of the addition of a service in bands that are heavily used by other services.

Section D: Fixed Service (FS), Including High Altitude Platform Systems (HAPS) and FSS Above 3 GHz

D1 (AI 1.8) – High Altitude Platform Stations in the 28/31 GHz and 47/48 GHz Bands

Background

Agenda Item 1.8 covered two major issues: 1) Resolution 145 (WRC-03): potential use of the bands 27.5-28.35 GHz and 31-31.3 GHz by HAPS in the FS; and 2) Resolution 122 (Rev. WRC-03): use of the bands 47.2-47.5 GHz and 47.9-49.2 GHz by HAPS in the FS and by other services. Although both Resolutions were addressed under this agenda item, only Resolution 122 implicates the Canadian Table through footnote No. 5.552A.

Resolution 122: The ITU has been considering the implications of HAPS in the FS in the 47.2-47.5 GHz and 47.9-48.2 GHz bands since 1997, when WRC-97 first made provision for the operation of HAPS within the FS. Studies have been ongoing under versions of Resolution 122 since WRC-97.

Resolution 122 (Rev. WRC-2000) indicated that sharing studies are yet to be completed between the fixed-satellite service (FSS) and HAPS operations in the FS. Pending the completion of the studies, Resolution 122 (Rev. WRC-2000) instructed the Radiocommunication Bureau "that from 22 November 1997, and pending review of the sharing studies in considering j) and review of the notification process by WRC-2000, the Bureau shall accept notices in the bands 47.2-47.5 GHz and 47.9-48.2 GHz only for high altitude platform stations in the FS and for feeder links for the broadcasting-satellite service (BSS), shall continue to process notices for FSS networks (except for feeder links for the broadcasting-satellite service) for which complete information for advance publication has been received prior to 27 October 1997, and shall inform the notifying administrations accordingly." In other words, notices received after 22 November 1997, from non-BSS feeder link FSS networks in the 47.2-47.5 GHz and 47.9-48.2 GHz bands, have not been accepted.
 
Resolution 122 (Rev. WRC-03) extended the restriction on processing of notices for FSS networks other than those providing service exclusively within Region 2. It also instructed the Bureau to maintain, until a date to be decided by a future WRC, notices concerning HAPS that were received by the Bureau prior to 22 November 1997, and provisionally recorded in the Master International Frequency Register. The studies regarding HAPS in the 47.2-47.5 GHz and 47.9-48.2 GHz bands have been completed and the results are contained in Recommendation ITU-R SF.1481-1. This Recommendation makes clear that co-frequency operations between HAPS in the FS and FSS networks and systems are feasible in the 47.2-47.5 GHz and 47.9-48.2 GHz bands, even while noting that "there may be a need to develop the maximum allowable power flux density at satellites on the GSO due to aggregate interference caused by ground user terminals of high altitude platform networks." Resolution 122 (Rev. WRC-03) confirms that co-existence between HAPS in the FS and the FSS at 47.2-47.5 GHz and 47.9-48.2 GHz is feasible, as administrations were encouraged to facilitate inter-service coordination.

In Resolution 122 (Rev. WRC-03), the ITU-R was invited to study power limitations on HAPS ground stations to facilitate sharing with space station receivers, as well as regulatory provisions to address deployment of HAPS in the FS near country borders. Technical sharing criteria between HAPS in the FS and both radio astronomy and FSS systems were also studied (taking into account the operational environments and the requirements of FSS systems). With the exception of interference to and from FSS spacecraft, and border area coordination matters in the FS, the deployment of HAPS is considered a national issue.

Summary of Proposed Table Changes

No allocation changes were made for this agenda item as a result of WRC-07; however, some changes were made to No. 5.552A.

MOD 5.552A The allocation to the fixed service in the bands 47.2-47.5 GHz and 47.9-48.2 GHz is designated for use by high altitude platform stations. The use of the bands 47.2-47.5 GHz and 47.9-48.2 GHz is subject to the provisions of Resolution 122 (RevWRC-9707). (WRC-07)

Discussion

Resolution 122 (Rev. WRC-03) was significantly revised to include, in a new resolves, hard on- and off-axis e.i.r.p. density limits on HAPS ground terminals to protect the FSS. For the protection of the FS, PFD limits at the Earth's surface were included in a new resolves. In addition, a "sunset date" (1 January 2012) by which networks must be brought into use was imposed on HAPS systems received by the Radiocommunication Bureau before 22 November 1997.

Section E: Services in LF, MF and HF Bands and Maritime Mobile Service

E1 (AI 1.13) - Review of Allocations in HF Bands between 4 and 10 MHz

Background

The aim of the WRC-07 was to consider allocation changes in the bands between 4 and 10 MHz, taking into account the requirements of all services.

Summary of Proposed Changes to Canadian Table

No allocation changes were made as a result of WRC-07; however, some changes were made to some footnotes in order to ensure consistency with decisions from previous world radio conferences.

E2 (AI 1.14) - Operational Procedures and Requirements of the Global Maritime Distress and Safety System (GMDSS) and New Technologies in the VHF Maritime Mobile Band

Background

WRC-07 agenda item 1.14 addressed mainly two issues: the transition to the GMDSS and the introduction of new technologies in the VHF maritime mobile band. The development of GMDSS began more than two decades ago, and its global implementation for vessels subject to the International Convention for the Safety of Life at Sea (SOLAS) became effective on 1 February 1999. The transition to GMDSS, however, remains ongoing for the foreseeable future, as there are many vessels not subject to SOLAS that are not yet fitted with GMDSS. To reflect the current status of the transition to the GMDSS, WRC-07 updated the associated regulatory procedures and requirements, including some Article 5 footnotes.

WRC-07 was also asked to consider necessary changes to Appendix 18 in order to enable the use of new technologies by the maritime mobile service (in the VHF maritime mobile band). Some of these changes necessitated additional modifications to Article 5.

The use of these bands by the land mobile and fixed services shall not cause harmful interference to nor claim protection from the maritime mobile VHF radiocommunication service.
ADD Cxx See Section A2.

Discussion

In view of the transition to the GMDSS and consistent with the intent that the ITU's Radio Regulations reflect current maritime operations, WRC-07 reallocated the 500 kHz Morse code international distress and calling frequency given that it was no longer used for radiotelegraphy (e.g. NAVTEX). Although the band 495-505 kHz was modified to reflect a primary mobile service allocation, the maritime mobile service maintained its priority through footnote 5.82B.

The review of GMDSS requirements also revealed that the GMDSS digital selective calling (DSC) frequency, 156.525 MHz (channel 70), was not afforded the same international recognition and protection in Article 5 as the pre-GMDSS distress and calling frequency, 156.8 MHz (channel 16). With this in mind, WRC-07 modified the International Table to provide an exclusive maritime mobile service allocation for the DSC frequency similar to the allocation provided for the maritime VHF channel 16 frequency. The impact to incumbent services, however, was minimized by maintaining existing fixed and mobile allocations in the guard bands of the DSC channel through footnotes with appropriate conditions.

Given the status of the transition to the GMDSS, WRC-07 agreed to integrate some non-GMDSS provisions from Appendix 13 into the GMDSS provisions in Chapter VII and to suppress Appendix 13. Consequentially, several Article 5 footnotes were modified to remove references to Appendix 13 and to reflect other required updates and corrections based on the regulatory review of maritime-related provisions.

In the context of introducing new technologies in the VHF maritime mobile band, significant interest was expressed in the development and advancement of satellite-based reception of Automatic Identification System (AIS) signals to permit identification and tracking of vessels at much greater distances than currently possible by terrestrial means. In response, WRC-07 added a secondary mobile satellite service (Earth-to-space) allocation to provide for satellite reception of the AIS signals on the existing AIS 1 and AIS 2 channels, 161.975 MHz and 162.025 MHz respectively.

E3 (AI 1.15) - Secondary Allocation to Amateur Service in the 135.7-137.8 kHz Band

Background

For more than two decades, radio amateurs have been increasingly interested in experimenting with communications at low frequencies, and several countries around the world have granted allocations to the amateur service in the band 135.7-137.8 kHz. Radio amateurs conducting low-frequency experiments in this frequency band have taken measures to avoid interference to the operations of the primary users of the band, and no cases of interference have been reported. The aim of the WRC was to allocate the band 135.7-137.8 kHz to the amateur service on a secondary basis, along with a power limitation to protect the other services using the band.

Discussion

There was worldwide consensus at WRC-07 to add a secondary allocation to the amateur service in the band 135.7-137.8 kHz, including a footnote limiting the amateur service maximum radiated power to 1 W e.i.r.p. Canada will align the Canadian Table with the international allocation.

Section F: Other Modifications to Canadian Table

F1 (AI 1.1) – Requests from Administrations to Delete Their Country Footnotes or to Have Their Country Name Deleted from Footnotes, if no Longer Required, in Accordance with Resolution 26 (Rev. WRC-97)

Resolution 26 (Rev. WRC-97) urges administrations to review footnotes periodically and to propose the deletion of their country footnotes or of their country names from footnotes, as appropriate. In exceptional cases, the Resolution 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.

Also, further resolves 1 to Resolution 26 permit the consideration of additions or modifications of footnotes, but only when they relate to the Conference agenda or if the Conference decides to include it in its agenda as a result of the consideration of proposals submitted by one or more interested administration(s).

Requests from other countries to modify footnotes currently included in the Canadian Table:

MOD 5.56  The stations of services to which the bands 14-19.95 kHz and 20.05-70 kHz and in Region 1 also the bands 72-84 kHz and 86-90 kHz are allocated may transmit standard frequency and time signals. Such stations shall be afforded protection from harmful interference. In Armenia, Azerbaijan, Belarus, Bulgaria, the Russian Federation, Georgia, Kazakhstan, Mongolia, Kyrgyzstan, Slovakia, the Czech Rep., Tajikistan and Turkmenistan, the frequencies 25 kHz and 50 kHz will be used for this purpose under the same conditions. (WRC-073)

Such use is limited to digital audio broadcasting and is subject to the provisions of Resolution 528 (Rev. WRC-03), with the exception of resolves 3 in regard to the limitation on broadcasting-satellite systems in the upper 25 MHz(WRC-20007)
MOD 5.394 In the United States, the use of the band 2 300-2 390 MHz by the aeronautical mobile service for telemetry has priority over other uses by the mobile services. In Canada, the use of the band 2 30060-2 483.500 MHz by the aeronautical mobile service for telemetry has priority over other uses by the mobile services. (WRC-07)
MOD C13A (CAN-095) Additional Allocation: The band 2 320-2 345 MHz is also allocated designated to the broadcasting satellite service (sound) and complementary terrestrial broadcasting service on a primary basis. Spectrum utilization policies provide the inter-service relationship with respect to broadcasting service operation.

Discussion

Through the adoption of these modifications to No. 5.393, there is recognition of Canada's use of the broadcasting-satellite allocation for its satellite radio services (Sirius Canada and XM Canada).

Through the adoption of these modifications to No. 5.394 an alignment with Canada's domestic footnote C12 for aeronautical mobile telemetry applications in the 2.3 GHz range is made.

F3 Domestic Proposals to Remove Irrelevant International Footnotes from Table

The Canadian Table contains international footnotes from the International Table that are deemed pertinent and thus adopted in Canada. The following footnotes are currently included in the Canadian Table, but are not relevant to the use of the allocation or band in Canada.

The Department proposes to completely remove these footnotes from the Canadian Table:

SUP 5.78 Different category of service: in Cuba, the United States of America and Mexico, the allocation of the band 415-435 kHz to the aeronautical radionavigation service is on a primary basis.
SUP 5.80 In Region 2, the use of the band 435-495 kHz by the aeronautical radionavigation service is limited to non-directional beacons not employing voice transmission.
SUP 5.118  Additional allocation: in the United States, Mexico, Peru and Uruguay, the band 3 230-3 400 kHz is also allocated to the radiolocation service on a secondary basis. (WRC-03)
SUP 5.153 In Region 3, the stations of those services to which the band 15 995-16 005 kHz is allocated may transmit standard frequency and time signals.
SUP 5.256A Additional allocation: in China, the Russian Federation, Kazakhstan and Ukraine, the band 258-261 MHz is also allocated to the space research service (Earth-to-space) and space operation service (Earth-to-space) on a primary basis. Stations in the space research service (Earth-to-space) and space operation service (Earth-to-space) shall not cause harmful interference to, nor claim protection from, nor constrain the use and development of the mobile service systems and mobile-satellite service systems operating in the band. Stations in space research service (Earth-to-space) and space operation service (Earth-to-space) shall not constrain the future development of fixed service systems of other countries. (WRC-03)
SUP 5.286E* Additional allocation: in Cape Verde, Indonesia, Nepal, Nigeria and Papua New Guinea, the bands 454-456 MHz and 459-460 MHz are also allocated to the mobile-satellite (Earth-to-space) service on a primary basis. (WRC-97)

Even with these modifications, the Department still considers this international footnote irrelevant in the context of the Canadian Table of Frequency allocation.

SUP 5.288  In the territorial waters of the United States and the Philippines, the preferred frequencies for use by on-board communication stations shall be 457.525 MHz, 457.550 MHz, 457.575 MHz and 457.600 MHz paired, respectively, with 467.750 MHz, 467.775 MHz, 467.800 MHz and 467.825 MHz. The characteristics of the equipment used shall conform to those specified in Recommendation ITU-R M.1174-1. (WRC-03)

In the band 1 518-1 525 MHz stations in the mobile-satellite service shall not claim protection from stations in the mobile service in the territory of Japan. No. 5.43A does not apply. (WRC-03)
SUP 5.362A In the United States, in the bands 1 555-1 559 MHz and 1 656.5-1 660.5 MHz, the aeronautical mobile-satellite (R) service shall have priority access and immediate availability, by preemption if necessary, over all other mobile-satellite communications operating within a network. Mobile-satellite systems shall not cause unacceptable interference to, or claim protection from, aeronautical mobile-satellite (R) service communications with priority 1 to 6 in Article 44. Account shall be taken of the priority of safety-related communications in the other mobile-satellite services. (WRC-97)
SUP 5.416* The use of the band 2 520-2 670 MHz by the broadcasting-satellite service is limited to national and regional systems for community reception, subject to agreement obtained under No. 9.21. (WRC-03)

* This footnote has been modified by WRC-07 and reads as follows:

5.416 The use of the band 2 520-2 670 MHz by the broadcasting-satellite service is limited to national and regional systems for community reception, subject to agreement obtained under No. 9.21. The provisions of No. 9.19 shall be applied by administrations in this band in their bilateral and multilateral negotiations. (WRC-07)

Even with these modifications, the Department still considers this international footnote irrelevant in the context of the Canadian Table of Frequency Allocation.

SUP 5.417A

In applying provision No. 5.418, in Korea (Rep. of) and Japan, resolves 3 of Resolution 528 (Rev. WRC-03) is relaxed to allow the broadcasting-satellite service (sound) and the complementary terrestrial broadcasting service to additionally operate on a primary basis in the band 2 605-2 630 MHz. This use is limited to systems intended for national coverage. An administration listed in this provision shall not have simultaneously two overlapping frequency assignments, one under this provision and the other under No. 5.416. The provisions of No. 5.416 and Table 21-4 of Article 21 do not apply. Use of non-geostationary-satellite systems in the broadcasting-satellite service (sound) in the band 2 605-2 630 MHz is subject to the provisions of Resolution 539 (Rev. WRC-03). The power flux density at the Earth's surface produced by emissions from a geostationary broadcasting-satellite service (sound) space station operating in the band 2 605-2 630 MHz for which complete Appendix 4 coordination information, or notification information, has been received after 4 July 2003, for all conditions and for all methods of modulation, shall not exceed the following limits:

–122 dB(W/(m2MHz))                                   for 25° < θ ≤ 90°

where θ is the angle of arrival of the incident wave above the horizontal plane, in degrees. These limits may be exceeded on the territory of any country whose administration has so agreed. As an exception to the limits above, the pfd value of -122 dB(W/(m2 MHz)) shall be used as a threshold for coordination under No. 9.11 in an area of 1 500 km around the territory of the administration notifying the broadcasting-satellite service (sound) system. In addition, the pfd value shall not exceed –100 dB(W/(m2MHz)) anywhere on the territory of the Russian Federation.

In addition, an administration listed in this provision shall not have simultaneously two overlapping frequency assignments, one under this provision and the other under No. 5.416 for systems for which complete Appendix 4 coordination information has been received after 1 June 2005. (WRC-03)
