GL-10
Issue 1
June 2019

 

1. Background

In June 2019, Innovation, Science and Economic Development Canada (ISED), on behalf of the Minister of Innovation, Science and Economic Development, published a Decision on Releasing Millimetre Wave Spectrum to Support 5G (“the Decision”) through Canada Gazette notice SLPB-003-19. Through the Decision, ISED has indicated that it will consult on the licensing framework for flexible use, update earth station licensing rules and develop coordination rules in the future. As well, ISED stated that until the earth station licensing rules and coordination rules are finalized, earth stations in the millimetre wave bands will be licensed in accordance with an interim licensing guideline. Therefore, ISED will be applying the Interim Guideline specified in this document to facilitate the licensing of Earth exploration-satellite service (EESS) and space research service (SRS) earth stations in the frequency band 26.5-27.0 GHz and fixed-satellite service (FSS) earth stations in the frequency bands 27.0-28.35 GHz and 37.5-40.0 GHz.

2. Intent

This guideline will be used in all cases where prospective licensees apply to ISED to seek authorizations for EESS and SRS earth stations in the frequency band 26.5-27.0 GHz, and FSS earth stations in the frequency bands 27.0-28.35 GHz and 37.5-40.0 GHz, and where current licensees request amendments to existing satellite earth station licences as listed in annex A and B of this document. This guideline also describes the requirements for existing licensees who must provide information on their operations relating to their transmit contours as discussed in the Decision.

This guideline will remain in effect until ISED adopts earth station licensing and coordination rules to facilitate sharing between EESS/SRS/FSS earth stations and flexible use systems. Other licensing requirements for earth station applications (such as those specified in CPC-2-6-01, Procedure for the Submission of Applications to License Fixed Earth Stations and to Approve the Use of Foreign Satellites in Canada) and all the relevant provisions of the Radiocommunication Act and Radiocommunication Regulations continue to apply.

As indicated in the Decision, ISED recognizes the important and often critical role of satellite communications in providing connectivity in rural and remote areas such as the North. To facilitate earth station deployment in these areas, ISED intends to consult, through the licensing framework consultation, on a set of specific areas that could be afforded some flexibility when applying the licensing and coordination rules. In this Interim Guideline, flexibility is provided to earth stations operating in certain areas. Annex C contains a preliminary list of Tier 4 licence areas in which earth stations are exempted from certain provisions. Given that this list is subject to future consultation, the flexibility provided to earth stations operating in these licence areas (including relaxation of certain rules or exemption from certain provisions; see section 3) is on a provisional basis. Depending on the result of the consultation, these earth stations may be required to comply with additional provisions, including those from which they are currently exempt. Note that although Tier 4 licence areas are used throughout this document, the decision on flexible use licence areas will be developed through an upcoming licensing framework consultation.

Authorization for an earth station obtained under the Interim Guideline may also be subject to the licensing and coordination rules to be established in the future. ISED intends to gather experience on the use of this guideline in order to develop the licensing and coordination rules, and may modify this guideline as required.

The terms used in the Interim Guideline are defined in table 1, below.

Table 1 — List of definitions
Term Definition
Census metropolitan area (CMA)

For the purposes of applying this guideline, the Statistics Canada definition of census metropolitan area (CMA) applies.

For details refer to Dictionary, Census of Population, 2016.

Co-located earth station For the purposes of applying this guideline, an earth station is considered co-located with existing earth station(s) if the transmit/receive contour of the proposed earth station overlaps the transmit/receive contour of the existing earth station(s), regardless of whether these earth stations are located at the same site.
Incremental contour

For a scenario where the proposed earth station location is not co-located with any existing authorized earth stations, the incremental contour is the same as the transmit/receive contour of the proposed earth station.

For a scenario where the proposed earth station is co-located with existing authorized earth stations, the incremental contour is the portion of the proposed earth station transmit/receive contour that is not already covered by the transmit/receive contour of the existing authorized earth stations.

For more information, refer to annex F.

Incremental population

The incremental population is the population within the incremental contour.

For more information, refer to annex F.
Major infrastructure See annex E.
Major roadways See annex E.
Maximum radius of the transmit/receive contour The maximum radius of the transmit/receive contour is the maximum distance between the location of the earth station and edge of the transmit/receive contour.
Receive contour The receive contour is intended to represent a region within which there is a potential that the operation of a flexible use service system may cause harmful interference to the operation of the earth station.
Simple polygon A simple polygon is a shape consisting of straight, non-intersecting line segments or “sides” that are joined pair-wise to form a closed shape with no holes.
Spectrum grid cells As defined in Service areas for competitive licensing, issue 4, October 2015: The minimum size of the grid cell is 1 minute latitude × 1 minute longitude. Larger square grid cells, e.g. 3 minute × 3 minute cells or 15 minute × 15 minute cells, are implemented for interiors of service areas where fine granularity is not required.
Transmit contour The transmit contour is intended to represent a region within which flexible use service systems may experience harmful interference from the emissions of the proposed earth station.

3. Licensing guidelines for new earth stations

An application for a receiving EESS, SRS and FSS earth station licence in the frequency bands 26.5-27.0 GHz and 37.5-40.0 GHz, or an application for a transmitting FSS earth station licence in the frequency band 27.0-28.35 GHz must include a receive contour or a transmit contour as described below for each applicable transmitting or receiving earth station in the relevant frequency block in the 26.5-28.35 GHz and 37.5-40.0 GHz band plans illustrated in figures 1 and 2, respectively. For the purpose of applying this guideline, the frequency band 37.5-37.6 GHz shall be treated as an individual 100 MHz frequency block.

Description of figure 1

This figure shows the fixed and mobile services band plan for the 26.5 GHz to 28.35 GHz frequency band. It shows that the frequency range 26.5 GHz to 28.3 GHz is divided into 18 consecutive blocks of 100 MHz (labelled as frequency blocks A, B, C, D, E, F, G, H, J, K, L, M, N, P, Q, R, S and T), with one remaining block of 50 MHz in the frequency range 28.3 GHz to 28.35 GHz (labelled as frequency block U).

Description of figure 2

This figure shows the fixed and mobile services band plan for the 37.6-40.0 GHz frequency band. It shows that the frequency range 37.0 GHz to 37.6 GHz is labelled as “To be determined.” The frequency range from 37.6 GHz to 40.0 GHz is divided into 24 consecutive blocks of 100 MHz (labelled as frequency blocks A, B, C, D, E, F, G, H, J, K, L, M, N, P, Q, R, S, T, U, V, W, X, Y and Z).

As indicated in the Decision, ISED will develop coordination rules using a population-impact based approach to enable coexistence between flexible use stations and satellite earth stations in the millimetre wave bands. Specifically, the population-impact based approach will be based on setting limits on earth station deployment such that its deployment would not affect a material amount of the population in a given flexible use licence area.

For transmitting earth stations, ISED could establish exclusion zones where flexible use systems would not be able to claim protection unless an agreement is reached between the licensees.

For receiving earth stations, protection zones could be established where flexible use systems would only be able to deploy upon successful coordination with earth station licensees.

In order to establish these zones, the transmit/receive contours described below could be used. Additional coordination rules could also be developed. ISED will develop proposed coordination rules through consultation with stakeholders.

Aside from the requirements described in this guideline, earth station applicants must satisfy the requirements outlined in CPC-2-6-01, in order to obtain a licence.

3.1 Acceptable transmit/receive contours

3.1.1 Receive contour

For all receiving earth stations regardless of their locations, the applicant must submit a contour in the shape of a simple polygon specifying a region around the receiving earth station using the method described in annex D.

3.1.2 Transmit contour

For all transmitting earth stations regardless of their locations, the applicant must submit a contour in the shape of a simple polygon specifying a region beyond which the aggregate power flux density (PFD) of the proposed transmitting earth station and any other existing authorized co-located transmitting earth stations does not exceed, for more than 10% of the time, a value of -77.6 dBm/m2/MHz at 10 metres above ground level that is generated using the method described in annex D.

Recognizing that the transmit contour is estimated using engineering models, ISED may request a transmitting earth station licensee to demonstrate compliance through field measurements, if necessary.

In the event that the emissions from transmitting earth stations exceed the limit or cause harmful interference to flexible use systems operating in the same area, ISED may also require adjustment to radio and auxiliary equipment in radio stations to enable coexistence. ISED may conduct a review of the transmit contours submitted with earth station authorizations on a case-by-case basis.

3.2 Further requirements for the transmit/receive contours

For proposed earth stations located in a Tier 4 licence area listed in annex C, the earth station licence applicant is required to submit an analysis at the time the earth station licence application is submitted, to demonstrate that the following requirements are satisfied for each flexible use frequency block in which the proposed earth station will operate.

  • Maximum radius and area of the transmit/receive contour: The maximum radius of the transmit/receive contour (i.e. the maximum distance between the location of the earth station and edge of the contour) should be less than 30 km. The area of the transmit/receive contour should be less than 315 km2. If the maximum radius of the transmit/receive contour is greater than 30 km or the area of the transmit/receive contour is greater than 315 km2, authorization may be considered on a case-by-case basis, taking into consideration justifications submitted by the applicant that may include, but are not limited to:
    • the engineering calculations and assumptions used to produce the contour
    • the impact on any nearby populated areas
    • the rationale for siting the earth station at the location specified
    • demonstration that the proposed earth station would not unnecessarily encumber future fixed and mobile services operating in the same frequency block(s)

For proposed earth stations located in a Tier 4 licence area not listed in annex C, the earth station licence applicant is required to submit an analysis at the time the earth station licence application is submitted, to demonstrate that the following operational requirements are satisfied for each flexible use frequency block in which the proposed earth station will operate.

  • Maximum radius and area of the transmit/receive contour: The maximum radius of the transmit/receive contour (i.e. the maximum distance between the location of the earth station and edge of the contour) should be less than or equal to 10 km. The area of the transmit/receive contour should be less than 100 km2. If the maximum radius of the transmit/receive contour is greater than 10 km or the area of the transmit/receive contour is greater than 100 km2, authorization may be considered on a case-by-case basis, taking into consideration justifications submitted by the applicant that may include, but are not limited to:
    • the engineering calculations and assumptions used to produce the contour
    • the impact on any nearby populated areas
    • the rationale for siting the earth station at the location specified
    • demonstration that the proposed earth station would not unnecessarily encumber future fixed and mobile services operating in the same frequency block(s)
  • Avoidance of major infrastructure: The transmit/receive contour must not overlap any major infrastructure within a relevant census metropolitan area (CMA) as described in annex E.
  • Incremental Population limit: The incremental population that is affected by the authorization of the proposed earth station, as calculated using the transmit/receive contour and the method described in annex F must be less than or equal to the maximum permitted incremental population limit described in table 2, below.
Table 2 — Maximum permitted incremental population limit per proposed earth station in each flexible use frequency block
Population of the Tier 4 licence area where the proposed earth station is located Maximum permitted incremental population limit that could be affected by the authorization of the proposed earth station (see notes below), per flexible use frequency block
Greater than 500,000 people 2,500 people
Between 100,000 and 500,000 people 0.5% of the Tier 4 population
Less than 100,000 people 500 people

Notes: A description of the Tier 4 licence areas with corresponding incremental population limits, per earth station, per flexible use frequency block is provided in annex G using population data available at this time. Going forward, determination of Tier 4 population for earth station licensing shall be based on the most up-to-date population census data made available by ISED at the time the earth station licence application is submitted.

In the event that the transmit or receive contour overlaps more than one Tier 4 licence area, in determining compliance, the applicable maximum permitted incremental population limit corresponds with the Tier 4 licence area in which the proposed earth station will be located. The total population within the contour is then compared with this limit.

  • Maximum number of earth stations: For each flexible use frequency block, the proposed earth station will be counted as an additional earth station operating within a Tier 4 licensing area if the incremental population affected is greater than zero as a result of its authorization (i.e. some part(s) of the proposed earth station transmit/receive contour would fall outside the transmit/receive contour(s) of any existing authorized earth stations). Even where other requirements are satisfied, ISED will only authorize a proposed earth station in a particular frequency block where there are less than 10 earth stations authorized (including those listed in annex A and annex B where applicable) within the Tier 4 licence area where the proposed earth station will be located.

To assist in the licensing application process, a checklist to help applicants demonstrate compliance with the above requirements is included in table H1 of annex H. In addition, examples demonstrating compliance with requirements described in this licensing guideline are included in annex I.

ISED may review the submitted transmit/receive contours and work with operators to ensure that the submitted contours are generated in conformance with annex D, if necessary.

3.3 Meeting the requirements

All applicants for an earth station licence who meet the requirements outlined in the Interim Guideline will be eligible to be issued a licence with the standard terms and conditions.

Where the proposed transmitting or receiving earth station does not meet all of the conditions in this guideline but does meet the other applicable requirements, ISED may consider authorizing the earth station(s) on a no-interference, no-protection basis with respect to future flexible use licensees operating in the same frequency block on a case-by-case basis. In such cases, ISED may impose certain specific conditions on the authorization.

4. Contour information requirement for existing licensees listed in annexes A and B

As discussed in the Decision, in order to balance the need to ensure that the spectrum is used efficiently and to recognize the infrastructure investments made by existing earth station licensees listed in annexes A and B, ISED will allow their continued operations for an extended period of time.

All existing earth station licensees listed in annex A and B are required to submit their transmit contour described in section 3.1.2 above within 6 months of the publication of the Interim Guideline.

ISED may review the material and work with licensees to ensure that the submitted contours are generated in conformance with the method described in annex D.

5. Applications to modify an existing licence

Modifications to any existing licences, including the earth stations licensed in accordance with section 3 and those listed in annexes A and B that are located in Tier 4 licence areas listed in annex C, may be authorized, provided that licensees submit updated transmit/receive contours as appropriate (described in section 3.1 and 3.2) and are otherwise in compliance with their current conditions of licence.

Modifications to any existing licences, including the earth stations licensed in accordance with section 3 and those listed in annexes A and B that are not located in Tier 4 licence areas listed in annex C, may be permitted, provided that licensees submit updated transmit/receive contours as appropriate (described in section 3.1 and 3.2) and are otherwise in compliance with their current conditions of licence, and that their modifications do not result in an increase in potential for interference to future flexible use licensees. In order to demonstrate that there is no increase in potential for interference, an applicant must provide and demonstrate the following:

  • Frequency required: The overlapped flexible use frequency block is the same as those listed in the existing licence for the corresponding earth station.
  • Updated transmit/receive contour, as appropriate: The transmit/receive contour, as appropriate, resulting from the modification of the earth station licence or addition of a co-located earth station has no part falling outside the area covered by the contour for the original earth station.

To assist in the licensing application process, a checklist to help demonstrate compliance with the above requirements is included in table H2 of annex H.

The receive contour shall be generated for each flexible use frequency block (refer to figures 1 and 2 in section 3) that is overlapped by the proposed earth station’s operating frequencies. Applicants are expected to use best engineering practices that take into account factors such as the effect of terrain and man-made and natural obstructions, to the extent possible.

ISED recognizes that standards for the deployment of flexible use systems are not yet developed. Therefore, for the purposes of modelling the receive contour, applicants may use the following technical parameters to model flexible use systems in the fixed/mobile service:

It should be noted that the above technical parameters are offered for guidance and do not necessarily represent technical parameters that will be implemented in future flexible use system technical standards.

*EIRP: Equivalent isotropically radiated power

D2. Method for generating the transmit contour (applicable to all earth stations)

The transmit contour shall be generated based on the aggregate emissions of all co-located transmitting earth stations using any portion of the same flexible use service frequency block (refer to figures 1 and 2 in section 3) that is overlapped by the proposed earth station’s operating frequencies. Applicants are expected to use best engineering practices that take into account factors such as the effect of terrain and man-made and natural obstructions, to the extent possible. In addition, the transmit contour shall be modelled:

  1. for a PFD value of -77.6 dBm/m2 at 10 metres above ground level in 1 MHz that is exceeded for no more than 10% of the time
  2. using the technical parameters (e.g. transmit power, antenna gain) for each co-located earth station in the 1 MHz portion of the flexible use service frequency block that would produce the maximum peak aggregated PFD

Figure D1 gives an example to illustrate the application criteria b), above. In this example, there are four co-located earth stations operating on different portions of the same flexible use service frequency block. Figure D1 depicts the different emissions for each earth station. Each emission could have different technical characteristics and overlap in different portions of the flexible use service frequency block. The maximum peak aggregated PFD is most likely to occur in the 1 MHz frequency block where multiple emissions overlap. In this example, two candidates are highlighted in yellow for illustration: a 10 MHz and 5 MHz frequency segment. Supposing that the maximum peak aggregated PFD would occur in the 5 MHz segment, the applicant would generate the transmit contour using emissions A2, B2 and C1 in that 5 MHz segment.

Earth station emissions

Figure D1: Example depicting the emissions of four co-located earth stations operating in the same frequency block (the long description is located below the image)
Description of figure D1

This figure is an example that illustrates how to select the technical parameters for each co-located earth station in the 1 MHz portion of the flexible use service frequency block that would produce the maximum peak aggregated PFD.

This example shows four co-located earth stations, called earth stations A through D, operating on the same 100 MHz flexible use service frequency block. The emissions of each earth station span different portions of the 100 MHz frequency block:

  • earth station A operates two emissions, designated A1 and A2
  • earth station B operates two emissions, designated B1 and B2
  • earth station C operates two emissions, designated C1 and C2
  • earth station D operates one emission, designated D1

Each emission could have different technical characteristics and overlap in different portions of the flexible use service frequency block. The maximum peak aggregated PFD is most likely to occur in the 1 MHz frequency block where multiple emissions overlap.

In this example, there is a 10 MHz segment where emissions B1, C1 and D1 overlap in frequency, as well as a 5 MHz segment where emissions A2, B2 and C1 overlap in frequency. Supposing that the maximum peak aggregated PFD would occur in the 5 MHz segment, the applicant would generate the transmit contour using emissions A2, B2 and C1 in that 5 MHz segment.

Annex E — Description of major infrastructure

For the purposes of applying this guideline, major infrastructure includes, but is not limited to, any of the following that resides inside the boundaries of a census metropolitan area (CMA) (for these purposes, as defined by Statistics Canada):

Annex F — Method for determining the incremental population affected by the authorization of a proposed earth station

The population affected by the authorization of a proposed earth station in a particular Tier 4 licensing area is calculated based on the incremental number of people (population) that could be affected through the licensing of the proposed earth station. The incremental population is assessed by determining the number of individuals that would be covered by the incremental contour resulting from the authorization of the earth station.

For a scenario where the proposed earth station location is not co-located with any existing authorized earth stations, the incremental contour is the same as the transmit/receive contour of the proposed earth station.

For a scenario where the proposed earth station is co-located with existing authorized earth stations, the incremental contour is the portion of the proposed earth station transmit/receive contour that is not already covered by the transmit/receive contour of the existing authorized earth stations.

Spectrum grid cells (as defined by ISED) with associated census data will be used to calculate the incremental population contained in the incremental contour. An applicant must use the most recently available version of ISED’s grid cell data when demonstrating compliance with the requirements of this licensing guideline. ISED intends to publish all spectrum grid cell census information on the Spectrum Management and Telecommunications website. Until then, applicants should contact the local district office for a list of spectrum grid cells for area(s) around the proposed earth station in order to carry out the calculation required.

The incremental population affected by the authorization of the proposed earth station is computed assuming that the population is distributed uniformly within a particular grid cell. The incremental population affected by the proposed earth station is calculated by summing the fractional areas of each grid cell that are overlapped by the incremental contour. That is,

\[P_{inc} = \sum_{j=1}^{N_{GC}}POP(j)\frac{AO_{IC}(j)}{AO_{GC}(j)}\]

where

j
is the range of grid cells overlapped by the incremental contour;
Pinc
is the incremental population that is affected by the authorization of the proposed earth station;
POP(j)
is the population in grid cell j;
AOIC(j)
is the area defined by the portion of incremental contour that overlaps grid cell j;
AGC(j)
is the area of grid cell j; and
NGC
is the number of grid cells overlapped by the incremental contour.

Figure F1 below shows an example of a proposed transmitting earth station that is co-located with two existing authorized co-located earth stations. In this figure, the blue contour is the transmit contour for the two existing authorized co-located earth stations. The orange contour is the transmit contour of the two existing authorized earth stations and the proposed earth station.

Figure F1 — Proposed earth station transmit contour

Proposed earth station transmit contour  (the long description is located below the image)
Description of figure F1

This figure is a map that illustrates the transmit contour of a proposed earth station co-located with two existing authorized co-located earth stations.

The map is divided into grid cells in a checkerboard fashion. These are identified using alphanumeric indicators: A through D (vertically) and 1 through 6 (horizontally). Each grid cell includes the population for that area.

The map includes:

  • Two earth station icons representing the locations of the two existing authorized co-located earth stations (in grid cells B3 and B4)
  • One earth station icon representing the location of the proposed earth station (in grid cell B3)
  • Two major roadways to the east (which fall outside of the grid cells identified and are not overlapped by the transmit contour)

The transmit contour of the two existing authorized co-located earth stations is a polygon that covers portions of grid cells B2, B3, B4, B5, C1, C2, C3, C4, C5 and C6.

The transmit contour of the proposed earth station is a polygon that includes the transmit contour of the two existing authorized co-located earth stations, as well as an area that extends beyond the transmit contour of the two existing authorized co-located earth stations. It covers portions of grid cells A3, A4, B1, B2, B3, B4, B5, C1, C2, C3, C4, C5, C6, D2, D3 and D4.

Figure F2 below shows the incremental transmit contour, which is created by removing the sections of the orange contour that are overlapped by the blue contour.

Figure F2 — Incremental contour of the proposed earth station

Figure F2: Incremental contour of the proposed earth station  (the long description is located below the image)
Description of figure F2

This figure is a map that illustrates the incremental contour of a proposed earth station co-located with two existing authorized co-located earth stations.

It shows the same map as described in figure F1; however in this figure, the transmit contour of the two existing authorized co-located earth stations (which overlaps portions of grid cells B2, B3, B4, B5, C1, C2, C3, C4, C5 and C6) has been removed.

The incremental contour of the proposed earth station is the portion of the proposed earth station transmit contour that remains once the transmit contour of the existing authorized co-located earth stations has been removed. In other words, the incremental contour of the proposed earth station is the area that extends beyond the area already covered by the transmit contour of the existing authorized earth stations. This includes portions of grid cells A3, A4, B1, B2, B3, B4, B5, C1, C2, C3, C4, C5, C6, D2, D3 and D4.

The checklist in table H2 is intended to help applicants demonstrate compliance with section 5 of the Interim Guideline (applicable to applications for a modification to an earth station licensed in accordance with section 3, or earth stations listed in annex A or B that are not located in a Tier 4 area listed in annex C) for each flexible use frequency block overlapped by the operation of the proposed earth station.

Table H2 — Checklist to demonstrate compliance with section 5
Requirement Description Requirement satisfied?
Requirement to submit contours The applicant has already submitted transmit/receive contours, as appropriate, describing the impact of the earth station. Yes/No
Frequency required The overlapped flexible use frequency block is the same as those in their existing licence for the corresponding earth station. Yes/No
Potential increase in interference The proposed modification of the earth station does not increase the shape or size of the transmit/receive contour, as appropriate, and as calculated using the method described in annex D. Yes/No

Annex I — Examples demonstrating compliance with requirements described in this licensing guideline

This annex provides two examples that illustrate how compliance with the licensing guideline requirements could be demonstrated in an application for an earth station licence:

  1. An example where the proposed earth station is not co-located with any existing authorized earth stations.
  2. An example where the proposed earth station is co-located with two existing authorized earth stations.

Example A: No existing authorized earth stations co-located with proposed earth station

The applicant submits the contour for a proposed transmitting earth station that operates within a particular flexible use frequency block, as illustrated in figure I1. Figure I1 shows the surrounding major roadways (in black and yellow), as well as the population in each grid cell. For the purpose of discussion, the grid cells have been divided into tiles that are enumerated A through D (vertically) and 1 through 6 (horizontally). In this example, the proposed earth station:

  1. has emissions that overlap one flexible use frequency block
  2. is located in a Tier 4 licensing area with a population greater than 500,000 people and
  3. is located in a Tier 4 licensing area where there are six earth stations already authorized in the same frequency block

Figure I1 — Proposed earth station transmit contour for example A

Proposed earth station transmit contour for example A (the long description is located below the image)
Description of figure I1

This figure is a map that illustrates example A, where a proposed earth station is not co-located with any existing authorized earth stations.

The map is divided into grid cells in a checkerboard fashion. These are identified using alphanumeric indicators: A through D (vertically) and 1 through 6 (horizontally). Each grid cell includes the population for that area.

The map includes:

  • an earth station icon representing the location of the proposed earth station location (in grid cell B3)
  • two major roadways to the east (which fall outside of the grid cells identified and are not overlapped by the transmit contour)

The transmit contour of the proposed earth station is a polygon that covers portions of grid cells B2, B3, B4, C3, C4, D3 and D4. The incremental and transmit contours are the same in this example.

  1. Transmit contour: The transmit contour is generated using the method described in annex D.
  2. Maximum radius and area of the transmit contour: The maximum radius of the transmit contour is 3.1 km. The area of the transmit contour 6.21 km2. Since the maximum radius is less than 10 km and the area is less than 100 km2, the applicant is not required to submit information to justify the size of the contour.
  3. Avoidance of major infrastructure within the transmit contour: The transmit contour does not overlap any major infrastructure within a CMA as described in annex E. Therefore, the proposed earth station would meet the conditions of this provision.
  4. Incremental population limit: In this example, the incremental contour is the same as the transmit contour. The incremental population that could be affected by authorization of the proposed earth station is 602.01 people (calculation shown in table I1, below), which is less than the population limit of 2,500 people for Tier 4 licensing areas with a population less than 500,000 people (refer to table 2 in section 3). Therefore, the proposed earth station would meet the conditions of this provision.

*Calculated assuming a grid cell area of 2.054 km2 and rounded to the nearest one hundredth of a percent for the purpose of presentation. The calculation that produces the population affected in a grid cell uses the precise fraction and not the “percent of grid cell area” value presented in the table.

  1. Maximum number of earth stations: The population overlapped by the incremental contour represents an increase in the population within the Tier 4 licensing area that could be impacted by the authorization of the proposed earth station on the particular frequency block. Authorizing the proposed earth station would increase the count of the number of authorized earth stations to seven, which is less than the limit of 10 for the Tier 4 licensing area. Therefore, the proposed earth station would meet the conditions of this provision.

In summary, using the checklist provided in table H1 in annex H, the following evaluation to demonstrate compliance with the requirements described in the Interim Guideline is made:

evaluation to demonstrate compliance with the requirements
Requirement Description Requirement satisfied?
Transmit/receive contour The applicant has submitted a transmit/receive contour using the method described in annex D. Yes
Maximum radius and area of the transmit/receive contour The maximum radius and area of the transmit/receive contour are less than the values specified in section 3.2. If not, the applicant has submitted rationale justifying the need for a larger contour. Yes
Avoidance of major infrastructure The applicant has demonstrated that the transmit/receive contour does not overlap any major infrastructure within a CMA as described in annex E. Yes
Incremental population limit The applicant has demonstrated that the incremental population limit, as specified in table 2 of section 3 of the Interim Guideline, is not exceeded for the Tier 4 licensing area in which the proposed earth station is located using ISED-published grid cell data. Yes
Number of earth stations Licensing the proposed earth station would not result in the number of earth stations in the Tier 4 licensing area where the proposed earth station is located to exceed 10. Yes

In the above example, the applicant has demonstrated that it meets all the requirements specified in this guideline.

Example B: Two existing authorized earth stations co-located with proposed earth station

The applicant submits a transmit contour for a proposed transmitting earth station (drawn as a dark orange icon in figure I2) that operates within one flexible use frequency block. The earth station is co-located with two existing authorized earth stations (drawn as light-blue icons in figure I2. The transmit contour for the proposed earth station, which is drawn in orange in figure I2 takes into account the aggregate emissions of the proposed earth station and the two co-located authorized earth stations. The transmit contour of the two existing authorized earth stations are in light blue in figure I2.

In this example, the applicant’s earth station:

  1. has emissions that overlap one flexible use frequency block
  2. is located in a Tier 4 licensing area with a population greater than 500,000 people and
  3. is located in a Tier 4 licensing area where there are 10 earth stations already authorized in the same frequency block

Figure I2 — Proposed earth station transmit contour for example B

Proposed earth station transmit contour for example B (the long description is located below the image)
Description of figure I2

This figure is a map that illustrates example B, where a proposed earth station co-located with two existing authorized earth stations.

The map is divided into grid cells in a checkerboard fashion. These are identified using alphanumeric indicators: A through D (vertically) and 1 through 6 (horizontally). Each grid cell includes the population for that area.

The map includes:

  • Two earth station icons representing the locations of the two existing authorized co-located earth stations (in grid cells B3 and B4)
  • One earth station icon representing the location of the proposed earth station (in grid cell B3)
  • Two major roadways to the east (which fall outside of the grid cells identified and are not overlapped by the transmit contour)

The transmit contour of the two existing authorized co-located earth stations is a polygon that covers portions of grid cells B2, B3, B4, B5, C1, C2, C3, C4, C5 and C6.

The transmit contour of the proposed earth station is a polygon that includes the transmit contour of the two existing authorized co-located earth stations, as well as an area that extends beyond the transmit contour of the two existing authorized co-located earth stations. It covers portions of grid cells A3, A4, B1, B2, B3, B4, B5, C1, C2, C3, C4, C5, C6, D2, D3 and D4.

Since the proposed earth station is co-located with existing authorized earth stations, an incremental contour is required for calculating the incremental population affected by the authorization of the proposed earth station. The incremental contour is created by deleting the sections of the authorized earth station transmit contour that overlap the proposed earth station transmit contour, as illustrated in figure I3. In figure I3, the incremental contour is drawn as a shaded orange contour. Figure I3 also shows the surrounding major roadways (in black and yellow), as well as the population in each grid cell. For the purpose of discussion, the grid cells have been divided into tiles that are enumerated A through D (vertically) and 1 through 6 (horizontally).

Figure I3 — Incremental contour of proposed earth station for example B

Incremental contour of proposed earth station for example B (the long description is located below the image)
Description of figure I3

This figure is a map that illustrates the incremental contour of the proposed earth station in example B.

It shows the same map as described in figure I2; however in this figure, the transmit contour of the two existing authorized co-located earth stations (which overlaps portions of grid cells B2, B3, B4, B5, C1, C2, C3, C4, C5 and C6) has been removed.

The incremental contour of the proposed earth station is the portion of the proposed earth station transmit contour that remains once the transmit contour of the existing authorized co-located earth stations has been removed. In other words, the incremental contour of the proposed earth station is the area that extends beyond the area already covered by the transmit contour of the existing authorized earth stations. This includes portions of grid cells A3, A4, B1, B2, B3, B4, B5, C1, C2, C3, C4, C5, C6, D2, D3 and D4.

  1. Transmit contour: The transmit contour is generated using the method described in annex D, taking into account the aggregate emissions of the two existing authorized earth stations.
  2. Maximum radius of the transmit contour: The maximum radius of the transmit contour is 3.5 km. The area of the contour is 18.77 km2. Since the radius is less than 10 km and the area is less than 100 km2, the applicant is not required to submit information to justify the size of the contour.
  3. Avoidance of major infrastructure within the transmit contour: The transmit contour does not overlap any major infrastructure within a CMA as described in annex E. Therefore, the proposed earth station would meet the conditions of this provision.
  4. Incremental population limit: The incremental population that could be affected by the authorization of the proposed earth station is 900.70 people (calculation shown in table I2, below), which is less than the population limit of 2,500 people for Tier 4 licensing areas with a population greater than 500,000 people (refer to table 2 of section 3). Therefore, the proposed earth station would meet the conditions of this provision.

*Calculated assuming a grid cell area of 2.054 km2 and rounded to the nearest one hundredth of a percent for the purpose of presentation. The calculation that produces the population affected in a grid cell uses the precise fraction and not the “percent of grid cell area” value presented in the table.

  1. Maximum number of earth stations: In this example, the incremental contour has portions that are outside of the transmit contour of the existing authorized stations. Therefore, authorizing the proposed earth station would increase the count of the number of authorized earth stations in the particular Tier 4 licensing area to 11, which is more than the limit of 10 for the Tier 4 licensing area. Therefore, the proposed earth station would not meet the conditions of this provision.

In summary, using the checklist provided in table H1 in annex H, the following evaluation to demonstrate compliance with the requirements described in this guideline is made:

evaluation to demonstrate compliance with the requirements described in this guideline
Requirement Description Requirement satisfied?
Transmit/receive contour The applicant has submitted a transmit/receive contour using the method described in annex D. Yes
Maximum radius and area of the transmit/receive contour The maximum radius and area of the transmit/receive contour are less than the values specified in section 3.2. If not, the applicant has submitted rationale justifying the need for a larger contour. Yes
Avoidance of major infrastructure The applicant has demonstrated that the transmit/receive contour does not overlap any major infrastructure within a CMA as described in annex E. Yes
Incremental population limit The applicant has demonstrated that the incremental population limit, as specified in table 2 of section 3 of the Interim Guideline, is not exceeded for the Tier 4 licensing area in which the proposed earth station is located using ISED-published grid cell data. Yes
Number of earth stations Licensing the proposed earth station would not result in the number of earth stations in the Tier 4 licensing area where the proposed earth station is located to exceed 10. No

In the above example, not all requirements specified in this guideline have been met. Therefore, the earth station will not be authorized with a standard licence. See section 3.3 of this guideline for further information.
