Results of the 2007 World Radiocommunication Conference — Canadian Delegation Report

Introduction

The World Radiocommunication Conference (WRC-07), held under the auspices of the International Telecommunication Union (ITU), a specialized agency of the UN, took place in Geneva from 21 October to 16 November 2007.  Approximately 2800 delegates participated in the Conference, representing over 161 Member States, Sector Members and 104 observer organizations. The Canadian delegation was led by Bob McCaughern (IC/DGSE) as well as Bruce Gracie (IC/DGTP) and Marc Dupuis (IC/DGSE), Deputy Heads of Delegation, and composed of approximately 60 persons from both the government of Canada and the private sector.

After four weeks of intense negotiations and more than 400 proposals and other documents considered in response to 28 agenda items, WRC-07 concluded its work on 16 November 2007.  A significant number of important, treaty-binding decisions dealing with a range of complex technical and regulatory issues were taken.  These were consistent, in large measure, with Canadian positions and objectives agreed between government and industry stakeholders prior to the Conference. This report highlights, by agenda item, the WRC-07 results.

Agenda Item 1.1

Agenda Item 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);

Outcome/Results at the WRC
Canada's three proposals to the conference to modify existing footnotes to the Table of Frequency Allocations were adopted.  The first two proposals concerned the addition of Canada's name, while the third concerned a modification of a frequency band to an in-country footnote (No. 5.394).  In the first case, it permits the Department to have the flexibility for the possible future introduction of a wide range of applications (including mobile applications) and to have the opportunity to harmonize the use of the band 512–608 MHz in Region 2.  For the second case, it recognizes Canada's use of the S-band (2.3 GHz ) for satellite services.  Finally, in the last case, Canada's in-country footnote was modified to align it with its domestic footnote for Aeronautical Mobile Telemetry applications also in the 2.3 GHz range.

Satisfactory Outcome/Result
Canada's objectives were completely satisfied.

Agenda Item 1.2

Agenda Item 1.2to consider allocations and regulatory issues related to the Earth exploration-satellite (passive) service, space research (passive) service and the meteorological satellite service in accordance with Resolutions 746 (WRC-03) and 742 (WRC-03);

Issue A

Issue A: Expansion of the meteorological satellite allocation by 100 MHz around 18 GHz.

Outcome/Results at the WRC
WRC-07 decided to expand the meteorological satellite service allocation in the band 18.1–18.3 GHz on a regional basis. For countries in Region 2 (including Canada), the band 18.0–18.1 GHz is allocated to the MetSat on a primary basis in addition to the existing allocation in the band 18.1–18.3 GHz. As for Regions 1 and 3, the band 18.3–18.4 GHz is allocated to the MetSat service on a primary basis in addition to the existing allocation in the band 18.1–18.3 GHz.

Satisfactory Outcome/Result
The WRC-07 decision is in accordance with the Canadian position. Canada supported an Inter-American Proposal for an expansion in the lower part of the existing MetSat allocation from 18.0 to 18.1 GHz. The additional 100 MHz allocation will allow the next generation of MetSat stations to meet operational requirements while at the same time not constraining the development of high density fixed-satellite service (HDFSS) in the band above 18.3 GHz for Region 2.

Telesat plans to deploy HDFSS in the future. An expansion of the MetSat in the band above 18.3 GHz could have constrained the development of HDFSS system in Canada.

Issue B

Issue B : Revise 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.

Outcome/Results at the WRC
WRC-07 decided to recommend compliance with tighter power levels compared to the mandatory power limit of -3 dBW stipulated in the 2004 edition of the Radio Regulations (RR), for stations of the fixed and mobile services operating in the band 10.60–10.68 GHz. In addition, the existing mandatory power limit will continue to apply to stations of the fixed and mobile services. WRC-07 also recommended limitations for some operational parameters of EESS(passive) systems.

Satisfactory Outcome/Result
Canada is of the view that the result on this issue provides a good balance between the needs of the passive and active services. With these decisions, appropriate protection will be afforded to future EESS(passive) systems without unduly constraining the development of fixed and mobile systems in a band already heavily used by these systems. Canada is satisfied with the result achieved at the Conference.

List of Private Sector and/or OGDs with an Interest in the Item
Canadian manufacturers (example: SR Telecom) produce point-to-point and point-to-multipoint equipment for many foreign markets. In addition, Bell Canada & Rogers currently operate point-to-point systems in this band.
Environment Canada is a user of the data gathered by EESS (passive) systems.

Issue C

Issue C: Develop sharing criteria between Earth Exploration Satellite service (EESS) (passive) and fixed and mobile services (FSand MS) in the band 36–37 GHz.

Outcome/Results at the WRC
WRC-07 decided to adopt some criteria to facilitate sharing between EESS(passive) systems and fixed and mobile systems in the band 36–37 GHz. These sharing criteria consist of:

  • limitation for some operational parameters of EESS (passive) systems,
  • mandatory power limits for stations of the fixed and mobile services.

Satisfactory Outcome/Result
Considering the limited deployment of fixed and mobile systems in the band 36–37 GHz around the world, the mandatory power limits imposed on stations of future fixed and mobile systems as well as the limitation on some operational parameters of EESS (passive) systems will facilitate sharing between future passive and active systems in the band 36–37 GHz without unduly constraining their development. Canada is of the view that the result on this issue provides a good balance between the needs of the passive and active services. Canada is satisfied with the result achieved at the Conference.

Agenda Item 1.3

Agenda Item 1.3 – in accordance with Resolution 747 (WRC-03), consider upgrading the radiolocation service to primary allocation status in the bands 9 000–9 200 MHz and 9 300–9 500 MHz and extending by up to 200 MHz the existing primary allocations to the Earth exploration-satellite service (active) and the space research service (active) in the band 9 500–9 800 MHz without placing undue constraints on the services to which the bands are allocated;

Outcome/Results at the WRC
The radiolocation service was upgrade to the primary status in the bands 9 000–9 200 MHz and 9 300–9 500 MHz with footnotes to the Table of Frequency Allocations in Article 5 to protect the radionavigation services in these bands. The EESS(active) and SRS(active) primary allocations in the band 9 500–9 800 MHzwere extended by 200 MHzdownwards, with appropriate footnotes to the Table of Frequency Allocations in Article 5 to protect existing services and to ensure that the use of the extended spectrum would be limited to systems which cannot be accommodated in the original 300 MHzallocation.  An additional 100 MHz secondary allocation to EESS(active) was made in the band 9 800–9 900 MHzat the request of The European Conference of Postal and Telecommunications Administrations (CEPT), in view of technological developments since the drafting of the agenda item.  This new allocation was accepted only with appropriate regulatory measures to protect systems from both primary and secondary services to which the band 9 800–9 900 MHzis currently allocated.

Satisfactory Outcome/Result
Canada joined the Inter-American proposal (IAP) for this agenda item.  The outcomes are completely in line with the Canadian position.  As for the additional extension (allocation of 100 MHz to EESS (active) on a secondary basis), the Canadian Space Agency indicated that it could always use the additional data provided by the added accuracy resulting from measurements on a wider bandwidth.  Therefore Canada had a neutral to slightly positive view on this CEPT proposal.

Agenda Item 1.4

Agenda Item 1.4 – to consider frequency-related matters for the future development of IMT-2000 and systems beyond IMT-2000 taking into account the results of ITU-R studies in accordance with Resolution 228 (Rev. WRC03);

Outcome/Results at the WRC
The Conference adopted regulatory text to identify spectrum for advanced mobile systems, known as International Mobile Telecommunications (IMT), in four frequency bands.  These bands are 450–470 MHz, portions of the 698–862 MHz (698–806 MHz in Region 2 and some countries in Region 3, 790–862 MHz in Regions 1 & 3), the band 2 300–2 400 MHz and the 3 400–3 600 MHz band.  The identification of the 3 400–3 600 MHzband was done via opt-in footnotes (restricted to a number of countries) to the Table of Frequency Allocations in Article 5 that included severe restrictions associated with the use of IMT in this frequency range.  As such, Region 2 opted for an allocation to the mobile service on a primary basis in the band 3 400–3 500 MHz via a footnote to the Table of Frequency Allocation in Article 5 but without any identification of this band for use by a particular mobile application, i.e. IMT.

The Conference did not adopt IMT in another three frequency bands that were under consideration:  410–430 MHz, 2 700–2 900 MHz and 4 400–4 990 MHz.  Most of the existing footnotes to the Table of Frequency Allocations in Article 5 for the already identified bands were modified to use the generic "IMT" designation instead of "IMT-2000" as per the Canadian proposal.  Consequential changes and updates were made to the IMTResolutions (Resolutions 212, 223, 224 and 225).

Regarding the satellite component of IMT, the bands 1 518–1 525 MHz and 1 668–1 675 MHz were identified for its use. 

The Conference adopted a new Recommendation (Recommendation 206 [COM4/B] (WRC-07)) on studies for the possible use of an integrated ground component to the Mobile Satellite Systems operating in IMT satellite component bands.  This issue is in line with the Canadian policy RP-023.

Out of the work on agenda item 1.4 at this conference, a new agenda item for WRC-11 was approved which will study the use of the 790–862 MHz bands by mobile service applications in Regions 1 & 3.

Satisfactory Outcome/Result
The decision not to identify three candidate bands was completely in line with Canadian positions.  The identification of 450–470 and 698–806 MHz was also in line with Canadian positions.  Although Canada had originally supported 3 500–3 700 MHz for identification for IMT, it became obvious that the restrictions being imposed would make it very difficult to implement and operate IMT in that band so Canada joined the Region 2 approach as given above.

The result on the integrated ground component to MSSwas satisfactory to the Canadian proponent, MSV Canada, and the Recommendation was drafted with a view to address the potential concerns of TerreStar Canada and the Personal Communications Services (PCS)incumbents.

The overall outcome on this agenda item was satisfactory to Canada and Canadian industry.

Agenda Item 1.5

Agenda Item 1.5 – to consider spectrum requirements and possible additional spectrum allocations for aeronautical telecommand and high data rate aeronautical telemetry in accordance with Resolution 230 (WRC-03);

Outcome/Results at the WRC
Agenda Item 1.5 was seeking identification of spectrum to meet the demand for wideband aeronautical telemetry and associated telecommand for flight testing.
Studies were carried out in ITUWorking Party 8B in accordance with Resolution 230 (WRC-03) and have shown the need for access to an additional amount of spectrum for aeronautical mobile telemetry (AMT) between150 MHzand 650 MHz, dependant on the flight test environment, to meet the predicted demand for the design and testing of new complex and advanced aircrafts.

Bands between 3 and 16 GHzwere identified during the Conference preparatory work as possible candidates for AMTfor flight test only:

  • 5 030–5 091 MHz
  • 5 091–5 150 MHz
  • 5 150–5 250 MHz
  • 4 400–4 940 / 5 925–6 700 MHz

Canada's position was to ensure access to the bands 5 091- 5 150 MHz, 4 400–4 940 MHzand 5 925–6 700 MHzfor AMTfor flight test purposes only on a global basis, taking into account the protection of existing services to which theses bands were already allocated.

Canada had its position reflected in the Inter-American Proposals (IAP) for this agenda item as follows (ref:  WRC-07-C-0014 Addendum 1 (pages 20–23) Addendum 2 (page19- 44)):

  • No need of definition for AMTin the Regulations (IAP/14A1/5)
  • Operational command and control requirements for Unmanned Aerial System should not be considered under Agenda Item 1.5 (IAP/14A1/14)
  • No changes required in Article 5 with respect to the band 16 – 30 GHz(IAP/14A1/13)
  • New allocation in the band 5 091 – 5 150 MHzthrough a new provision No. 5.[444C] in accordance with a new resolution for aeronautical mobile service for flight test telemetry transmission by aircraft station (IAP/14A2/10 and 11) 
  • No change required in Article 5 with respect to the band 5 150 -5 250 MHz(IAP/14A2/12) 
  • Allow use of the bands 4 400 – 4 940 MHzand 5 925 – 6 700 MHzby systems in the aeronautical mobile service for flight test telemetry transmission by aircraft station through a new provision in accordance with a new Resolution. Radio Regulation No. 5.442 was also to be modified to reflect this proposal (IAP/14A2/13, 14, 15, 16).

Canada was not supporting an allocation to the Aeronautical mobile service in the band 5 030 -5 091 MHz. The band 5 030–5 150 MHzis allocated to aeronautical radionavigation service and is the core band for the deployment of a specific type of systems known as Microwave Landing Systems (MLS).

At the beginning of the conference, in view of the various regional positions on the proposed candidate bands, it became apparent that a fully global approach to satisfy the demand for AMTfor flight test was not achievable. While there was consensus for the band 5 091–5 150 MHz, it was not possible to agree on global allocation for the other candidate's bands.

The final decisions of the conference on this item:

  • No change to the band 5 030 – 5 091 MHz;
  • Global allocation to the aeronautical mobile service for, amongst other applications, AMTfor flight test in the band 5 091 – 5 150 MHzsubject to provision No. 5.444B [5.4B03] and Resolution 418 [COM4/4] (WRC-07);
  • In Region 1 (except in Algeria, Saudi Arabia, Bahrain, Egypt, United Arab Emirates, Jordan, Kuwait, Lebanon, Morocco, Oman, Qatar, Syrian Arab Republic, Sudan and Tunisia) and in Brazil, allocation to the aeronautical mobile service limited to AMTin the band 5 150–5 250 MHzthrough a new provision, No. 5.446C [5.4B04] and in accordance with Resolution 418 [COM4/4] (WRC-07);
  • In Region 2 (except Brazil, Cuba, French Overseas Departments and Communities, Guatemala, Paraguay, Uruguay and Venezuela), and in Australia, identification of the band 4 400–4 940 MHz for the use by systems in the aeronautical mobile service for flight test telemetry-transmission by aircraft stations (see No. 1.83) through the new provision No. 5.440A [5.4B05] and  in accordance with Resolution 416 [COM4/2] (WRC-07);
  • In Region 2 (except Brazil, Cuba, Guatemala, Paraguay, Uruguay and Venezuela), and in Australia, removal of the restriction on the use of mobile allocation by aeronautical mobile systems in the band 4 825–4 835 MHzto allow flight test telemetry transmission by aircraft stations in accordance with Resolution 416 [COM4/2] (WRC-07) and -revised No 5.442;
  • In Region 2 (except Brazil, Cuba, French Overseas Departments and Communities, Guatemala, Paraguay, Uruguay and Venezuela), identification of the band 5 925–6 700 MHzfor use by aeronautical mobile telemetry for flight testing by aircraft stations (see No. 1.83) through the new provision  -No. 5.457C [5.4B02]and in accordance with Resolution 416 [COM4/2] (WRC-07).

Satisfactory Outcome/Result
The outcome of the WRC-07 on AI 1.5 has been very positive from a Canadian point of view. Canada's positions were all taken in account and reflected in the final results. This will provide at least 59 MHzon a global basis and up to 1.3 GHzof spectrum accessible in the band 4 – 6 GHzin Region 2 for AMTapplications (flight test purposes). The technical and regulatory requirements set in the new resolutions also provide adequate protection to the existing services in the bands allocated, services which include fixed, fixed satellites and aeronautical radionavigation services.

List of Private Sector and/or OGDs with an Interest in the Item
The Canadian aeronautical manufacturing industry, particularly companies such as Bombardier Aerospace Inc. and Bell Helicopter Inc. which have installation and testing facilities in Canada. The results of the conference will allow them to develop further testing programs in Canada. These two companies represent up to 19,000 Canadians jobs in a high technology sector and combined annual revenue of around $ 9 billions CAN.

Agenda Item 1.6

Agenda Item 1.6 – to consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHzand 6 GHz, in accordance with Resolution 414 (WRC-03) and, to study current satellite frequency allocations, that will support the modernization of civil aviation telecommunication systems, taking into account Resolution 415 (WRC-03);

Outcome/Results at the WRC
Regarding additional allocations for aeronautical mobile (R) service (AM(R)S) between 108 MHzand 6 GHz(Resolution 414), the Conference made the following decisions:

  • New AM(R)S allocation in 112–117.975 MHz with protection provided to Ground Based Augmentation System (GBAS) and FMbroadcasting service through modification of No. 5.197A and Resolution 413.(Rev. WRC-07);
  • New AM(R)S allocation in the band 960–1 164 MHzin accordance with No.5.327A.[5.4B06];
  • New spectrum for AM(R)S applications at surface of airport in the band 5 091–5 150 MHzin accordance with No 5.444B. [5.4B03] and Resolution 748 [COM4/4] (WRC-07);
  • Removal of the precedence to Microwave Landing Systems (MLS)over any other uses in the band 5 091–5 150 MHz(known as the MLSextension band) through modification of Nos. 5.444 and 5.444A;
  • No AM(R)S allocation in the band 5 000–5 030 MHzbut an Agenda item for the next Conference to consider any regulatory measures to facilitate the introduction of new AM(R)S systems in this band.

Regarding the use of satellite frequency allocations for the use of civil aviation (Resolution 415 (WRC-03)), the Conference adopted a new Recommendation, Recommendation 724 [COM4/A] (WRC-07), which provides guidance for the use of Very Small Aperture Terminal (VSAT)terminals in support of civil aviation without constraints on or obligations to fixed-satellite operators.  Resolution 415 (WRC-03) was suppressed.

Satisfactory Outcome/Result
Regarding Resolution 414, the new AM(R)S allocations will provide additional spectrum for the implementation of data intensive applications to alleviate congestion in the current bands.

Regarding Resolution 415, the Conference adopted Recommendation 724 to encourage the implementation of VSAT systems that could support aeronautical communications as well as other communications requirements in developing countries and countries with remote and rural areas.  Since Recommendation 724 does not impose constraints or obligations to our fixed-satellite operators, Canada is satisfied with the result.

Agenda Item 1.7

Agenda Item 1.7 – to consider the results of ITU-R studies regarding sharing between the mobile-satellite service and the space research service (passive) in the band 1 668–1 668.4 MHz, and between the mobile-satellite service and the mobile service in the band 1 668.4–1 675 MHz in accordance with Resolution 744 (WRC-03);

Issue A

Issue A: Sharing between the Mobile Satellite Service (MSS) and the Space Research Service (SRS) (passive) in the band 1 668–1 668.4 MHz.

Outcome/Results at the WRC
WRC-07 decided to adopt the concept of coordination in order to facilitate sharing between the MSSand SRS(passive) in this band. In this context, frequency overlap and the MSSMobile Earth Station (MES) power spectral density and e.i.r.p.spectral density thresholds have been retained as the coordination triggers. The coordination trigger values for the MESpower spectral density and equivalent isotropically radiated power (e.i.r.p.)spectral density are -2.5 dBW/4 kHzand -10 dBW/4 kHzrespectively.  WRC-07 also adopted Resolution 904 [COM5/1] (WRC-07) on transitional measures for coordination between MSSand SRS(passive) filed to the ITUbetween WRC-03 and WRC-07.

Satisfactory Outcome/Result
WRC-07 decision is in accordance with the Canadian position. There was no IAP for this agenda item and as Canada, like the US, do not intend to use the MSSallocation, our interest was limited to the protection of the SRS, which will be achieved through coordination.

List of Private Sector and/or OGDs with an Interest in the Item
This band may be used by space based radio astronomy applications, as part of space very large baseline interferometry systems (S-VLBI). The Canadian radio astronomers (National Research Council) are interested in these applications.

Issue B

Issue B: Sharing between the MSSand the Fixed and Mobile Services (FS/MS) in the band 1 668.4–1 675 MHz.

Outcome/Results at the WRC
WRC-07 decided to limit the use of the mobile allocation in the band 1 668.4 – 1 675 MHzto transportable radio-relay systems except for the United States of America and Canada, which will be allowed to continue their fixed and mobile operations without any constraints.  Furthermore, in the band 1 670–1 675 MHz, stations of the fixed and mobile services operating in Canada and USAare exempted from the obligation to provide protection to MSSspace stations. These exceptions are reflected in the resolves of Resolution 744 as modified by WRC-07. In other administrations operating transportable radio relay systems, the e.i.r.p.spectral density of their stations should not exceed -27 dBW/4 kHzin the band 1 668.4- 1 675 MHzin the direction of geostationary orbit.

Satisfactory Outcome/Result
When making the allocation to MSSin 2003, the Conference adopted a number of regulatory measures to protect aeronautical mobile telemetry on the USterritory and exempted FS/MSsystems operating in the USfrom the obligation to protect MSSspace stations. It was critical for Canada to succeed in associating itself with this exemption. Canada may now auction this band and authorize mobile service systems to operate without constraints vis-à-vis MSS.
