Since the 1992 ITU World Administrative Radio Conference, through the adoption of an in-country footnote, a few countries including the United States, allocated the band 2310-2360 MHz to the broadcasting-satellite service and complementary terrestrial broadcasting service on a primary basis. Furthermore, the United States saw to designate the band 2320-2345 MHz for the establishment of two satellite digital audio radio services (S-DARS), including the installation of terrestrial S-DARS transmitters in urban areas to increase the satellite radio coverage.
Innovation, Science and Economic Development Canada (ISED), through its spectrum utilization policies, made the band 2320-2345 MHz available to accommodate similar satellite radio services in Canada based on using the US satellites. Subsequently, the Canadian Radio-television and Telecommunications Commission (CRTC) granted broadcasting licences to Canadian Satellite Radio Inc. (CSR) and SIRIUS Canada, and the government modified its satellite-use policy to permit these licensees to use the US S-DARS satellite facilities of XM Radio and SIRIUS Radio respectively, for the transmission of Canadian digital satellite subscription radio services in Canada. In 2011, following the merger of XM Radio and SIRIUS Radio in the United States, CSR and SIRIUS Canada received approval from the CRTC to also merge and create SiriusXM Canada Inc.
It should be noted that the bands 2305-2320 MHz and 2345-2360 MHz, which are adjacent to the S-DARS operations, are designated for Wireless Communication Service (WCS) applications under the fixed and mobile service allocations, and the spectrum has been auctioned to various licensees. Use of these bands for WCS is governed by ISED's Standard Radio System Plan SRSP-516, Technical Requirements for Wireless Communication Service (WCS) Operating in the Bands 2305-2320 MHz and 2345-2360 MHz, which includes provisions to manage the potential interference of out-of-band emissions between terrestrial S-DARS and WCS.
Noting that Canadian digital satellite subscription radio service undertakings are associated with US partners through commercial agreements and that close spectrum coordination for the terrestrial S-DARS transmitters is expected to be carried out between the Canadian and US licensees, bilateral coordination between Canada and the United States is not required. Figure 1 below describes the frequency sub-bands to be used for the satellite and terrestrial S-DARS transmitters by SiriusXM Canada Inc.
As the band 2320-2345 MHz is co-allocated with the fixed service, the Canadian satellite radio licensees are expected to reach a mutually acceptable arrangement with the existing fixed service licenseesFootnote 1 for fixed stations that are within 150 km of any terrestrial S-DARS transmitter. Furthermore, due to the WCS operations in bands adjacent to the satellite radio services, satellite radio licensees will be required to cooperate, or at times reach an arrangement, with the WCS operators depending on the location of the terrestrial S-DARS transmittersFootnote 2. Sections 3.5 and 3.6 below describe these requirements.
Radiated out-of-band emissions of the terrestrial S-DARS transmitter shall be -75 dBW or less, relative to an isotropic radiator, when measured with a resolution bandwidth of 1 MHz. The limit applies to all bands outside the band occupied by the terrestrial and satellite components of the S-DARS service.
Effective Isotropic Radiated Power (e.i.r.p.): The effective isotropic radiated power (e.i.r.p.) is the product of the transmitter output power, the transmission line (and combiner) efficiency and the maximum power gain of the antenna relative to an isotropic radiator.
Effective Radiated Power (ERP): The effective radiated power (ERP) is the product of the transmitter output power, the transmission line (and combiner) efficiency and the maximum power gain of the antenna relative to a dipole radiator.
e.i.r.p. = ERP + 2.15 dB when expressed in dBW
e.i.r.p. = ERP × 1.64 when expressed in W
Urban and Rural Areas: As of 2011, Statistics Canada defines a population centre as an area with a population of at least 1 000 and a density of 400 or more people per square kilometre. Small, medium and large urban population centres are defined as having a population of between 1 000 and 29 999, 30 000 and 99 999, and 100 000 and over, respectively. Population centres are considered urban areas. All areas outside population centres are defined as rural areas.
The MapInfo boundary files for population centres are available at the Statistics Canada website:
The maximum permissible operating power is 12.5 kW e.i.r.p. This is calculated using the maximum value of radiation from the antenna in the plane of maximum radiation and, for directional antennas, in the direction of maximum radiation.
An application is required for:
- the construction of a new terrestrial S-DARS transmitter or facility; and
- a modification to an existing terrestrial S-DARS transmitter which impacts on its coverage, such as the addition of transmitters, and changes to the e.i.r.p., antenna height, antenna pattern or location.
Table 1 in Section 3.8 summarizes these application requirements.

3.3 Radio Frequency (RF) Exposure, Land-Use and Public Consultations, Immunity-Related Interference, Environmental Assessments and Transport Canada / NAV CANADA Safety-Related Issues
Note: This section applies only to terrestrial S-DARS facilities that exceed 50 W e.i.r.p.
The procedures, as outlined in Section 1.4 of BPR-1, shall be followed.
Note: This section applies only to terrestrial S-DARS facilities that exceed 50 W e.i.r.p.
WCS licensees in the bands 2305-2320 MHz and 2345-2360 MHz may experience or cause interference from or to S-DARS licensees. SRSP-516 sets out the requirements that apply to these WCS licensees for sharing information regarding the location and operation of base and fixed stations (with the exception of fixed subscriber stations) with S-DARS licensees.
This section sets out the requirements that apply to S-DARS licensees for sharing information regarding the location and operation of terrestrial S-DARS repeaters with WCS licensees.
Terrestrial S-DARS transmitters that are to be implemented for the purpose of augmenting the satellite coverage within urban areas, and that meet the requirements for technical certification, will need to be located in consultation with those WCS operators, licensed and operating, within the urban area to maximize co-existence of both services. If licensed WCS are not in operation, information on the current and future terrestrial S-DARS locations needs to be provided to the WCS licensees in a timely manner, in order to facilitate the current and long-term plans of both the WCS and S-DARS licensees.
For terrestrial S-DARS transmitters whose e.i.r.p. is greater than 50 W (17 dBW) and that are located outside urban centres or intended to improve coverage outside urban centres, the S-DARS licensee will need to seek an arrangement with any WCS licensee within the coverage area of the terrestrial S-DARS transmitter. Written confirmation of an arrangement shall be provided to the Department. Upon request, the Department will provide a list of the existing WCS licensees within the coverage area.
The respective licensees must work in collaboration to develop a suitable arrangement before the deployment of facilities. It is expected that the time frame to develop such an arrangement will not exceed 30 calendar days. In the event that a mutually acceptable arrangement cannot be concluded between licensees, either licensee may ask the Department to facilitate resolution of the issue.
For each terrestrial S-DARS transmitter, the licensee is expected to reach a mutually acceptable arrangement with the licensee of any existing fixed service within a 150-km radius, if the bandwidth of the fixed service overlaps the bandwidth of the terrestrial S-DARS. The respective licensees must work in collaboration to develop a suitable arrangement before the deployment of the facilities. Written confirmation of an arrangement shall be provided to the Department. In the event that a mutually acceptable arrangement cannot be concluded within 30 calendar days of the initial contact between licensees, either licensee may ask the Department to facilitate resolution of the issue.
Broadcast receivers and their associated equipment, as well as non-radio equipment (e.g. radio-sensitive devices), are expected to operate properly within field strengths lower than those indicated in the Electromagnetic Compatibility Advisory Bulletin EMCAB-2, Criteria for Resolution of Immunity Complaints Involving Fundamental Emissions of Radiocommunications Transmitters. The Department uses EMCAB-2 to make determinations on interference or immunity cases.
The broadcasters will be responsible for solving immunity-type interference in the case of valid complaints (see Section 3.7.4).
The guidelines on resolving immunity issues related to radio-sensitive equipment are outlined in ISED's Client Procedures Circular CPC-3-14-01, Determinations of Harmful Interference with Respect to Radio-Sensitive Equipment. This CPC can also be used as a guide for resolving immunity-related interference to broadcast receivers and associated equipment.
In predicting high field strength contours, the ERP should be based on the appropriate vertical plane radiation pattern of the antenna for the azimuthal direction in question.
For distances less than 1.5 km from the transmitting site, the field strength should be calculated using the following free space formula:
F = 137 + 10 log (ERP) − 20 log (d)
- F is the field strength in BµV/m (dB above one microvolt per metre);
- ERP is the effective radiated power in watts at the pertinent depression angle; and
- d is the slant distance (in metres) between the centre of radiation of the antenna and the receiving location.
The following types of complaints are judged not valid by the Department and, therefore, terrestrial S-DARS operators are not responsible for resolving them:
- complaints attributed to immunity-type interference to broadcast receivers and associated equipment that are located in an area where the measured field strength does not exceed 125 dBµV/m;
- complaints attributed to immunity-type interference to radio-sensitive equipment that is located in an area where the measured field strength does not exceed 130 dBµV/m; and
- any other complaint deemed not valid by the Department.

Description of Figure A1
Figure A1 of Annex A is an example of an elevation diagram of a typical tower and transmitting antenna. The tower is drawn as a vertical pole and the antenna is shown as a small vertical structure attached to the tower. The ground level is drawn as a horizontal line running at the base of the tower. The line representing the average elevation of terrain is drawn as a horizontal line slightly below ground level. Mean sea level is shown as a horizontal line at the bottom of the graphic, below the average elevation of terrain. Also, a horizontal line runs from the vertical centre of the antenna and is identified as the Radiating Centre.
There is a bidirectional arrow between the top of the tower and the line at ground level, indicating that the tower rises 300 metres above ground. Below, there is a bidirectional arrow between the line of the average elevation of terrain and the line at mean sea level, indicating there are 190 metres between the two.
Next, a bidirectional arrow between the line at ground level and the line at mean sea level indicates that the mean sea level is 211 metres below ground level.
Next, the space between the top of the tower and the top of the antenna is surrounded by two pointing arrows and is labelled as being 5 metres high. Below, there is a bidirectional arrow that indicates that the antenna is 35 metres tall.
In addition, there is a bidirectional arrow between the radiating centre of the antenna and the line at ground level, labelled as representing a distance of 277 metres.
Next, there is a bidirectional arrow between the radiating centre of the antenna and the line of the average elevation of terrain, which indicates that the radiating centre is 298 metres above the average level of terrain.
Next, there is a bidirectional arrow between the line marking the radiating centre of the antenna and the line at mean sea level, indicating that there are 488 metres between the two.
Format of the Antenna Radiation Pattern
For the vertical and horizontal patterns, data shall be taken relative to maximum gain (boresight = 0°). For the vertical and horizontal pattern, a sufficient number of points shall be selected to provide an accuracy of ±0.5 dB in the main beam of the antenna (a range of 0 to -10 dB from the maximum) and an accuracy of 1 dB in all other directions.
A text file, as per the specifications in Annex E of BPR-1, must be prepared for the composite antenna pattern.
