Notice No. DGTP-004-01 — Proposal to Introduce the Mobile Service on a Co-primary Basis with the Broadcasting Service in the Frequency Band 746–806 MHz
The purpose of this Notice is to initiate public consultation through the release of the above-mentioned spectrum policy proposal document that seeks to introduce the mobile service in the frequency band 746–806 MHz (Television Broadcasting Channels 60–69). It is proposed to allow the mobile service to operate in the above band with the broadcasting service on coprimary basis. Through a spectrum policy consultation, the Department would subsequently seek to identify, where possible, a modest amount of spectrum in the above band for public safety and possibly for commercial mobile services taking into account the DTV transition.
The Department has established a Digital Television (DTV) Transition Allotment Plan which will enable most Canadian Broadcasters to implement DTV in television channels 2–59. Although there are currently some DTV allotments in channels 60–69, the Department believes that a modest amount of spectrum may still be made available to meet the pressing spectrum needs of public safety and possibly commercial mobile services.
A document entitled Proposal to Introduce the Mobile Service on a Co-primary Basis with the Broadcasting Service in the Frequency Band 746–806 MHz is available for public comment. These comments will provide the basis for making domestic spectrum allocation changes and to assist in the development of a future consultation paper to identify spectrum for the mobile service.
Industry Canada invites interested parties to provide their views and comments on the above referenced proposed spectrum policy document.

Telecommunications Policy Branch
The purpose of this policy paper, announced in Gazette Notice DGTP-004-01, is to initiate public consultation and invite comments on proposals to introduce the mobile service to operate on co-primary basis with the broadcasting service in the frequency band 746–806 MHz (Television Channels 60–69). The proposals outlined in this spectrum policy paper seek to make changes to the Canadian Table of Frequency Allocations that will accommodate the identification of a modest amount of spectrum in the aforementioned frequency bands for public safety and possibly for commercial mobile services taking into account the DTV transition.
The Department invites interested parties to comment on these proposals in accordance with the time line outlined in Gazette Notice DGTP-004-01.
The work of the Task Force on the Implementation of Digital Television (DTV)1 culminated on October 21, 1997 with the release of a series of recommendations in the document entitled, Canadian Television in the Digital Era. This report detailed how Canada should make the transition to digital television with industry and government working together. Since the release of the DTV Task Force recommendations, Industry Canada has moved quickly to address the spectrum-related technical recommendations to implement DTV in Canada through the:
- negotiation and adoption of North American technical standards for DTV;
- development and release of the DTV Transition Allotment Plan;
- demonstration and testing, in association with Canadian Digital Television Inc. (CDTV Inc.), of various DTV encoding and broadcasting technologies through the establishment of the experimental DTV transmitter site in Manotick, Ontario; and
- negotiation of a Canada/US frequency coordination agreement and the development and release of DTV-related Broadcasting Procedures.
The DTV Transition Allotment Plan has set aside one digital channel for every existing regular analogue television station until the end of the transition to digital television. Regular power stations were given priority over low power stations in the development of the Transition Allotment Plan. In 1988, Canadian broadcasters, for marketing and business reasons, decided to adopt a "fast-follow" strategy allowing them to follow the US rollout by about 2 years. This strategy was chosen to enable sufficient time for broadcasting facilities to gradually ramp-up to full implementation of digital broadcasting. A gradual ramp-up would permit broadcasters to implement DTV in primary broadcasting markets in cities across Canada as the market demand and the DTV penetration rate increased. It also recognized the requirement for substantial capital expenditures with no immediate new sources of revenue, to convert television production and transmission facilities to digital broadcasting during a period of analogue and digital simulcasting.
However, there are emerging pressures that may require broadcasters to develop a business plan that accelerates the conversion to digital broadcasting. This may be due, in part, to increasing competition to over-the-air broadcasting from satellite and cable delivery of digital broadcasting programming and the complementary multimedia role of the Internet. In addition, the US is already moving at an aggressive pace to rollout DTV and phase out analogue broadcasting by 2006. This US schedule will result in release of spectrum in channels 60–69 (also referred to as the 700 MHz band) for new wireless services. Europe is also implementing DTV at a rapid pace.
The US DTV reassignment plan for the 700 MHz band is already well underway and Canada is facing increasing pressure to designate certain portions of this spectrum for mobile services. Pressing spectrum demand is coming from the public safety community on both sides of the Canada/US border to accommodate advanced law enforcement and safety services. Accommodating such spectrum demand would result in the delivery of more effective public safety services for the well-being of all Canadians.
The shortage of mobile spectrum below 1 GHz in large urban centres like Toronto, Montreal and Vancouver has reached critical levels. Spectrum managers, in some cases, have had to reclaim commercial mobile frequency assignments to temporarily meet the spectrum demand for public safety services and public utilities. In many instances, new requests for spectrum by commercial entities have had to be denied due to the resulting spectrum shortage. Moreover, a number of events of international scope are being contemplated in Toronto, such as the Youth Congress in 2002 and the bid to host the 2008 Olympics. Both these events will require extraordinary measures to secure sufficient mobile spectrum. There is also an increase in the spectrum demand for commercial mobile services that connects Canadians to the knowledge-based economy via the Internet.
A near term goal for initiating this consultation is to eventually propose the identification of a modest portion of spectrum, in channels 60–69, to accommodate public safety and commercial mobile requirements while meeting the needs of broadcasters in their rollout of DTV. The Department believes it is possible to accomplish this goal with a relatively minimal impact on the rollout of DTV in Canada. For example, broadcasters who want to quickly move to broadcast DTV programming and whose channels are temporarily allotted in channel 60–69 (until being moved below channel 60) are encouraged to seek a DTV channel below channel 60. This would benefit broadcasters who quickly move to DTV by providing them earlier access to a permanent channel below channel 60. This would alleviate the costs of moving twice to different DTV channels. At the same time, this will free up spectrum above channel 60 to accommodate mobile services.
It may be too early yet to determine how over-the-air DTV broadcasting will eventually rollout, i.e. whether the rollout will be gradual or in phases for certain population centres or right across the country. There are expectations that consortiums of broadcasters will initially form business partnerships to share common facilities to reduce the costs of DTV rollout and maximize the market opportunities. In this regard, on January 4, 2001, Industry Canada authorized CDTV Inc. to operate an experimental transmitter site in Toronto, on a trial basis, to test DTV technologies and services.
The Department believes that this is an opportune time to begin consultation on the reassignment of some of this spectrum.
In April of 1999, Industry Canada released the DTV Transition Allotment Plan which provided all broadcasters operating an analogue channel access to an equivalent DTV channel for analogue and digital simulcasting for a period of time. The Allotment Plan envisaged that the core spectrum for DTV broadcasting would eventually reside in channels 2–59. Some allotments were assigned in channels 60–69 during the transition period to accommodate simulcasting.
While the DTV Transition Allotment Plan was able to accommodate most broadcasters below channel 60, other planning constraints such as sharing spectrum along the Canada/US and certain technical requirements precluded accommodating all regular power broadcasting facilities below channel 60. As a result, there are a certain number of digital allotments made for an interim period between channels 60–69, particularly in some major urban centres.
The US developed a DTV Transition Allotment Plan with relatively few allotments in channels 60–69. As previously outlined, the FCC has established a schedule for DTV implementation and designated spectrum in channels 60–69 for wireless services. The following chart highlights the Federal Communications Commission's (FCC) plan for the reallocation of spectrum in the frequency range 746–806 MHz.
(Refer to Annex 1 for more details of the FCC Plan)
The US requirement for spectrum coordination in the 700 MHz band, for public safety and other commercial mobile services along the Canada/US border, is significant. In order for both countries to use their domestic spectrum for broadcasting and/or mobile services, sharing arrangements must be negotiated to ensure that radio service in one country does not interfere with radio service in the other. This poses some unique issues when the allocations are different. In this case, the US has set aside 24 MHz for public safety and 36 MHz for commercial wireless services. In the frequency range 746–806 MHz, some 6 MHz of commercial mobile spectrum (guard band) has been auctioned and the remaining 30 MHz is scheduled to be auctioned this year. There are practical reasons for Canada and the US to harmonize their spectrum allocations, whenever possible, in order to respond to the public interest and to realize economic benefits. A compelling reason for Canada to seek common spectrum with the US for public safety use in this frequency range is to ensure that our law enforcement and safety agencies develop compatible networks and effective services with US public safety agencies.
Industry Canada will participate in a frequency coordination process with the US government that recognizes the eventuality of some mobile spectrum becoming available for use in the Canada/US border area on a shared basis in accordance with well-established sharing principles.
At the June 2000 World Radiocommunication Conference (WRC-2000), held under the auspices of the International Telecommunication Union (ITU) in Istanbul, Turkey, Canada proposed and was successful in having its name added to international in-country footnote S5.293. This footnote allocates certain broadcasting bands on a co-primary basis with the fixed and mobile services. In preparation for WRC-2000, Industry Canada and the wireless industry recognized that many countries in the Americas, including the US and Mexico, had international allocations to implement fixed and mobile in parts of the UHF television bands. It was decided that Canada should add its name to this Region 2 ITU footnote. This international allocation would provide flexibility for Canada to consider a domestic allocation change to implement mobile and fixed services in parts of the UHF television bands. Of course this would be subject to full public consultation and a subsequent spectrum policy. This would also enable the development of spectrum sharing arrangements with the US on an equal basis for mobile services.
Industry Canada believes that it is timely to modify the Canadian Table of Frequency Allocations to incorporate international footnote S5.293 and to permit some mobile service use in the frequency band 746–806 MHz based on a future spectrum policy. The Department proposes modifications to the Canadian Table of Frequency Allocations as follows:
Mobile CWW CZZ
This proposed allocation change would provide flexibility to implement the mobile service in parts of the UHF television bands and enable the development of spectrum sharing arrangements with the US on an equal basis for the mobile service. In addition, the intent of proposed Canadian footnote CWW is to indicate a future consultation process to identify a modest amount of spectrum for release to mobile services. The intent of Canadian footnote CZZ is to ensure that core DTV broadcasting spectrum, in the frequency bands 470–512 MHz and 614–746 MHz, is preserved. The potential implementation of mobile service is predicated on the development of a spectrum utilization policy, for the gradual release of spectrum for the mobile service, within a public consultation process that also recognizes the needs of the broadcasting service.
