- Proposed Designation of the Bands 770-776 MHz and 800-806 MHz for Public Safety and Revisions to the Band Plan
- Proposed Continued Accommodation of Wideband Operations
- Proposed Transition from the Current Band Plan to the Proposed Band Plan
- Annex A
The objective of this paper is to obtain views on the designation of TV channels 64 and 69 for public safety; revision to the narrowband public safety frequency plan; and transitional measures that support moving systems to the revised band plan.
In the past, Industry Canada consulted on designating the bands 764-776 MHz (TV channels 63 and 64) and 794-806 MHz (TV channels 68 and 69) for public safety in the land mobile service. As a result of this consultation, the bands 764-770 MHz (TV channel 63) and 794-800 MHz (TV channel 68) were designated to public safety and the Department indicated that it would consult again in the future on making the same designation in the bands 770-776 MHz (TV channel 64) and 800-806 MHz (TV channel 69).
In August 2007, the Federal Communications Commission (FCC) issued a Second Report and Order (FCC-07-132) to change its public safety frequency plan to accommodate a requirement for broadband systems. Previously, the Canadian and U.S. band plans were aligned and the technical rules governing the equipment characteristics were largely harmonized.
Canada and the United States have adopted a cross-border frequency sharing arrangement for public safety systems in the 700 MHz band, which provides both countries with ready access to this spectrum and identified common mutual aid channels that could facilitate interoperability between public safety agencies in the border areas. The result of these changes means that Canada's current band plan is now completely out of alignment with the United States.
The Department is seeking comment on whether the 700 MHz frequency plan should be changed to align with the new band plan developed by the United States. Secondly, if Canada decides to remain harmonized with the United States, the bands 770-776 MHz (TV channel 64) and 800-806 MHz (TV channel 69) must be designated for public safety, and the transition from the current band plan to the new band plan must be considered.
Industry Canada has recently discussed this matter with several public safety service providers and equipment manufacturers. The following observations can be made from these informal discussions:
- Harmonization of the 700 MHz band with the United States is critical for radio equipment economies of scale and interoperability.
- There is an immediate need to continue to deploy narrowband public safety systems.
- Although broadband public safety systems are an important matter, the accommodation of narrowband systems should take priority, as a number of public safety organizations are making plans to deploy these systems in the 700 MHz band.
- Deployment under the existing band plan has just begun and the number of existing systems is low; therefore, considering a new band plan is timely.
As a result, the Department has developed proposed options based the above four points. Interested parties are invited to examine this proposal carefully and to provide comments that will help the Department to formulate a way forward on this matter.top of page
In October 2004, Industry Canada issued a Spectrum Utilization Policy (SP-746 MHz) Footnote 1 that made mobile service allocations in the 700 MHz band and designated the bands 764-770 MHz and 794–800 MHz (TV channels 63 and 68 respectively) for public safety. As a result, the Department took measures to clear channels 63 and 68 of TV allotments, thus providing spectrum for immediate licensing of public safety systems. In SP-746 MHz , the Department also indicated the likelihood of identifying the bands 770–776 MHz (TV channel 64) and 800-806 MHz (TV channel 69) for public safety use pending the digital television (DTV) transition of existing television stations. At that time, no date had been set for the transition from analog to digital television.
On June 27, 2005, Industry Canada announced the signing of a new arrangement with the United States for the use of the radio spectrum in the bands 764-776 MHz (TV Channels 63, 64) and 794-806 MHz (TV Channels 68, 69) for public safety systems. This new arrangement, known as Arrangement GFootnote 2, was based on a common channelling plan that identified blocks of frequencies for narrowband and wideband voice and data applications, as well as mutual aid channels and channels for low-power use. This spectrum was harmonized with the United States in order to support interoperability requirements in the border area and to enable public safety users to benefit from radio equipment economies of scale.
In June 2006, the Department issued a Radio Systems Policy (RP-06)Footnote 3 that set forth the general rules for licensing public safety systems in the 700 MHz spectrum. This document established that the frequencies be licensed on a first-come, first-served basis and that equipment must be capable of using the mutual aid channels under an interoperable standard set by the Department.
Following the release of RP-06 , in consultation with the Radio Advisory Board of Canada, the Department developed the technical rules which were published in September 2006 in a Standard Radio System Plan (SRSP-511)Footnote 4. In addition, the equipment certification rules were similarly developed and published in the Radio Standards Specification (RSS-119)Footnote 5. SRSP-511 defined the channelling plan and established the spectrum sharing criteria for narrowband and wideband systems. These technical rules were generally harmonized with the United States.
In September 2006, the Department opened the 700 MHz band for licensing public safety systems, see Figure 1 . Several public safety organizations expressed interest in using the 700 MHz public safety spectrum for either replacing existing VHF/UHF facilities or adding to capacity in congested areas to current networks in the 800 MHz range where additional spectrum is not available. Consequently, systems are in the early stages of being planned or deployed in the 700 MHz band.
Figure 1 - Upper 700 MHz Band Plan in 2006
After Hurricane Katrina in 2005, the U.S. government decided that there was a clear need for a national public safety network capable of broadband communications. As a result, the United States started to consider restructuring its public safety 700 MHz spectrum to accommodate emerging broadband applications and address the need for improved interoperability at the national level. Throughout late 2006 and until summer 2007, the FCC undertook major consultations to deal with both the commercial and public requirements in the 700 MHz spectrum. In August 2007, the FCC issued a Second Report and Order (FCC-07-132) that restructured the 700 MHz band, which included the following decisions:
- The identification of 10+10 MHz of spectrum for a national broadband public safety network.
- The consolidation of the existing narrowband spectrum in upper part of the 700 MHz band and the elimination of the 6+6 MHz of wideband spectrum.
- The licensing basis to create public/private sector entity to develop and manage the 700 MHz broadband public safety network.
Figure 2 - New U.S. Band Plan Established in August 2007
Since the U.S. decision, Industry Canada has received many comments and questions from the public safety community about the future use of the 700 MHz band in Canada. Public safety organizations want to know if the Canadian band plan is going to be revised in a similar fashion to the United States. The most immediate concern is the need for public safety agencies to have continued access to the 700 MHz band to deploy narrowband systems due to the high congestion levels in major urban centers in other bands, such as 800 MHz. Consequently, the Department has decided to take a two-step approach:
- Consider restructuring the narrowband spectrum. This would include the issue of future wideband applications.
- Consider the public safety broadband requirements in Canada and the possibility of identifying spectrum for this use
The narrowband consultation is the focus of this paper. The broadband issue will follow in a separate consultation.top of page
3. Proposed Designation of the Bands 770-776 MHz and 800-806 MHz for Public Safety and Revisions to the Band Plan
The public safety community has been clear from the outset that harmonized use of the 700 MHz band in Canada and the U.S. is important and would be beneficial. Throughout the consultations leading to the Department's licensing and technical standards for the 700 MHz band, there was strong support to align Canada's rules with the United States. Given the U.S. changes to the 700 MHz band, Canada no longer has any public safety bands that are harmonized with the United States. Furthermore, in the VHF and UHF bands, some portions used exclusively by public safety differ from one province to the next and sometimes even from one municipality to the next.
Consequently, the Department has developed a proposal to harmonize the Canadian 700 MHz band plan with the new U.S. plan.
Under the current Canadian band plan, narrowband and wideband systems are authorized in the bands 770-776 MHz (TV channel 64) and 794-800 MHz (TV channel 68). Figure 3 shows the differences between the new U.S. band plan and the current Canadian plan.
Figure 3 - Comparison of the New U.S. and the Current Canadian Band Plans
Access to TV channels 64 and 69 would be required if Canada were to harmonize our narrowband public safety spectrum with the United States. On May 17, 2007, the CRTC published Broadcasting Public Notice CRTC 2007-53, which adopted August 31, 2011 as the shut-down date for analog television transmission. Consequentially, Industry Canada has assessed the impact of accessing TV channels 64 and 69, and noted the following:
- Currently, there are seven television stations operating in channels 64 and 69 (see Table A1). There are also four DTV allotments in channel 64 and seven in channel 69 (see Table A2). Southern Ontario is the most affected having four on-air TV stations and three DTV allotments.
- The stations that currently occupy channels 64 and 69 may be on-air until 2011 and the DTV allotments can be used until 2011.
It is clear that, for most of Canada, channels 64 and 69 could be used immediately for narrowband public safety with no impact on television broadcasting.
In order to achieve harmonization of narrowband public safety systems, the Department proposes the following:
- In addition to the bands 764-770 MHz (TV channel 63) and 794-800 MHz (TV channel 68), to designate the bands 770-776 MHz (TV channel 64) and 800-806 MHz (TV channel 69) for public safety in the land mobile service.
- To adopt the band plan as follows in Figure 4 and Figure 5 that accommodates licensing of narrowband systems in the bands 769-775 MHz and 799-805 MHz.
The Department is seeking comments on the above proposals.
Figure 4 - Proposed Canadian Band Plan
Figure 5 - Proposed Public Safety Spectrum in the 700 MHz Band
Under this proposal, it is possible to maintain the current technical rules for the use of the narrowband channels found in the present SRSP-511. The channelling plan, power levels, protection to television in the adjacent channels, definitions of low power and interoperability channels would not need to be changed. In fact, the first 3+3 MHz (769-772 MHz/799-802 MHz) will have the same channelling structure as is set in SRSP-511 for the bands 764-767 MHz and 794-797 MHz. For the next 3+3 MHz (772-775 MHz/802-805 MHz) the intent would be to implement the channelling that is currently set out in Arrangement G and to apply the same technical requirements that are set out in SRSP-511. The revisions to SRSP-511 will also need to include co-channel protection for television operating on TV channels 64 and 69 from public safety.
It should be noted that Blocks C (775-776 MHz/805-806 MHz) are used in the United States as a guard band to protect public safety from the commercial operations in the adjacent bands and have been auctioned for commercial use with rules to mitigate interference to public safety. Similarly, Blocks B (768–769 MHz/798-799 MHz) are used in the United States as a guard band between narrowband and broadband public safety.top of page
The current Canadian band plan allows wideband operation in the bands 767-770 MHz and 797–800 MHz. It is the Department's intent to continue allowing limited wideband operation under the proposed band plan (Figure 4 and 5) and the Department proposes the following two options:
Allow aggregation of the narrowband channels in the bands 769-775 MHz and 799-805 MHz.
Option 1 will allow limited wideband operations without having to deal with the issues of interference from the adjacent bands, but this could reduce the number of narrowband channels available. The issues of coexistence with narrowband operations in the same spectrum and spectrum efficiency would need to be addressed.
Allow wideband operations in Blocks B and/or Blocks C as identified in Figures 4 and 5.
Option 2 will allow wideband operations without taking away the much needed narrowband channels. With this option, issues regarding interference from the adjacent bands should be addressed as they will be consulted on in the future.
Some radiocommunication systems, both narrowband and wideband, have already been licensed according to the current band plan in the bands 764-770 MHz and 794-800 MHz. The Department proposes that these radiocommunication systems continue to be deployed as planned and that licensees be given time to transition to the proposed new band plan.
Also, there are some areas where TV channels 64 and 69 are not available and may not be available for public safety radiocommunication systems until after August 2011.
Given that there are several existing public safety radiocommunication systems licensed under the current band plan in the bands 764-770 MHz and 794-800 MHz and in some areas of the country the new spectrum in TV channels 64 and 69 is not available, the Department proposes the following:
- Existing public safety radiocommunication systems may remain in operation as licensed under the current band plan. However, they will have to be retuned to the new band plan no later than two years after the new band plan comes into effect.
- New public safety radiocommunication systems may continue to be licensed under the current band plan if the spectrum in the new band plan is not available due to television use or DTV allotments in TV channels 64 and 69. However, the public safety licensee will have up to one year to move to the new band plan after the television spectrum becomes available.
- Replacement channels will be held in reserve in the new band plan for these licensees in the lower portion of the band (i.e. 769-772 MHz and 799-802 MHz). The licensing of new radiocommunication systems according to the new band plan will begin at the upper portion of the band (i.e. 772-775 MHz and 802-805 MHz).
Until the new band plan has been finalized, any licensing will be subject to the condition that the equipment be frequency agile in order that it can be retuned to the final band plan.
