1. Intent

This Standard Radio System Plan (SRSP) states the minimum technical requirements for the efficient spectrum utilization of ancillary terrestrial component (ATC) equipment in the bands 2000–2020 MHz and 2180–2200 MHz. This SRSP specifies the technical characteristics relating to efficient spectrum usage only and is not to be regarded as a comprehensive specification for equipment design and/or selection.

2. General

Even if a radio station or system complies with the requirements of this SRSP, Industry Canada may require modifications to the station or system whenever harmful interferenceFootnote 1 is caused to any other licensed radio station or system.

The arrangements for non-standard systems are outlined in Spectrum Utilization Policy SP‑Gen, General Information Related to Spectrum Utilization and Radio Systems Policies.

Industry Canada should be advised when potential conflicts between radio systems cannot be resolved by the parties concerned. After consulting with these parties, Industry Canada will determine what modifications need to be made and establish a schedule for carrying out these modifications in order to resolve the conflict. For instance, Industry Canada may require licensees to use system receiver selectivity characteristics that provide improved rejection of harmful interference.

Advanced wireless service (AWS) equipment must be certified in accordance with Radio Standards Specification RSS‑170, Mobile Earth Stations (MESs) and Ancillary Terrestrial Component (ATC) Equipment Operating in the Mobile‑Satellite Service (MSS) Bands.

Licensees are required to provide Industry Canada, upon request, with information on certain technical parameters of their radio systems.

Revisions to this SRSP will be made as required.

4. Band Plan

The band plan for the bands 2000–2020 MHz and 2180–2200 MHz is described in Figure 1 below. The bands are divided in 2 pairs of 10 MHz blocks.

The band 2000–2020 MHz is designated for uplink or downlink operations to or from ATC base stations. Industry Canada will allow the ATC licensee to decide if the terrestrial use of the band will be for uplink or downlink operations. The licensee must notify Industry Canada of the decision by May 20, 2016. The decision regarding the uplink or downlink operations will apply to all of Canada for the rest of the licence term.

The band 2180–2200 MHz is designated for downlink operations from ATC base stations to user equipment.

Fixed systems that support the MSS or ATC systems of the existing licensee may be permitted in the bands 2000–2020 MHz and 2180–2200 MHz as long as they adhere to the technical requirements set out for ATC equipment in these bands.

Figure 1: 2 GHz ATC Band Plan
Figure 1: 2 GHz ATC Band Plan (the long description is located below the image)

This figure shows the block pairing at 2 GHz. There are two 10 + 10 MHz paired blocks, labelled A (2000–2010 MHz) and A’ (2180–2190 MHz), and B (2010–2020 MHz) and B’ (2190–2200 MHz). Blocks A and B are designated for terrestrial uplink or downlink operations, and blocks A’ and B’ are designated for terrestrial downlink operations.

5. Technical Criteria

5.1 Radiated Power and Antenna Height Limits for Base Stations

The equivalent isotropically radiated power (e.i.r.p.) of base stations shall not exceed 1640 W when transmitting with an emission bandwidth of 1 MHz or less, and 1640 W/MHz when transmitting with an emission bandwidth greater than 1 MHz.

Base stations located outside of large or medium population centresFootnote 2 may increase their e.i.r.p. to a maximum of 3280 W when transmitting with an emission bandwidth of 1 MHz or less, and to 3280 W/MHz when transmitting with an emission bandwidth greater than 1 MHz.

A licensee operating a base station utilizing an e.i.r.p greater than 1640 W/MHz must coordinate in advance with all AWS–4Footnote 3 licensees authorized to operate on adjacent frequency blocks within the same band.

Base station antenna heights above average terrain may exceed 300 m with a corresponding reduction in e.i.r.p. in accordance with Table 1.

Table 1: Maximum Allowable e.i.r.p. for HAAT
HAATFootnote 4 (metres) Maximum e.i.r.p. (watts)
HAAT≤300 3280 or 1640
300≤HAAT≤500 1070
500≤HAAT≤1000 490
1000≤HAAT≤1500 270
1500≤HAAT≤2000 160

5.2 Radiated Power and Antenna Height Limits for Mobile Stations

The maximum e.i.r.p. limits for mobile stations operating in the bands 2000–2020 MHz and 2180–2200 MHz are specified in RSS‑170.

5.3 Criteria for Transmitter Unwanted Emissions

The standard specifications for transmitter unwanted emissions are set out in RSS‑170.

6. Protection of Mobile‑Satellite Services (MSS) in the Bands 2000–2020 MHz and 2180–2200 MHz

The operation of ATC base stations in the bands 2000–2020 MHz and 2180–2200 MHz shall not cause harmful interference to and shall accept any interference from MSS operations in these bands.

7. Co‑existence of Systems Operating in Adjacent Bands

Coordination may be required with licensees in adjacent bands. Licensees should consult Industry Canada for the most up‑to‑date list of licensees in the area in adjacent bands prior to deploying stations.

Possible interference conflicts resulting from the operation of ATC and radio systems in adjacent bands may occur even though the technical specifications of both this SRSP and RSS‑170 are being met. The resolution of such conflicts should be reached through mutual arrangements between the affected parties following consultation and coordination.

When potential conflicts between systems cannot be resolved in a timely fashion, Industry Canada shall be so advised, whereupon following consultations with the parties concerned, the Department will determine the necessary course of action.

7.1 Personal Communications Service Systems Operating Between 1995 MHz and 2000 MHz

If the band 2000–2020 MHz is used for uplink operations, operators in the bands 2000–2020 MHz and 1995–2000 MHz are required to manage interference from base station transmitters operating in the band 1995–2000 MHz into base station receivers operating in the band 2000–2020 MHz through mutually acceptable coordination agreements, if necessary.

If the band 2000–2020 MHz is used for downlink operations, the power of emission from an ATC base station operating in the band 2000–2020 MHz shall be attenuated below the transmitter power by at least 43 + 10log10 p dB at the 2000 MHz band edge and below.

7.2 Mobile Systems Operating Above 2020 MHz and Below 2180 MHz

The power of emission from an ATC base station operating in the bands 2000–2020 MHz and 2180–2200 MHz shall be attenuated below the transmitter power by at least 43 + 10log10p dB at the 2020 MHz band edge and above, and at the 2180 MHz band edge and below.

Coordination may be required between mobile systems operating above 2020 MHz (J–Block) and below 2180 MHz (AWS–3) and ATC base stations operating in the bands 2000–2020 MHz and 2180–2200 MHz.

7.3 Space Operation Service, Earth‑Exploration Satellite Service and Space Research Service Operating Between 2200 MHz and 2290 MHz

No ATC base station operating in the band 2180–2200 MHz shall be located less than 820 m from an earth station facility operating in the band 2200–2290 MHz.

The power of emission from an ATC base station operating in the band 2180–2200 MHz shall not exceed −100.6 dBW/4kHz at the 2200 MHz band edge and above.

8. International Coordination

Through their conditions of licence, ATC licensees (also referred to as AWS-4 licensees) will be required to abide by certain technical requirements and to coordinate with US licensees in accordance with the conditions of any international arrangements or agreements into which Canada enters.

An arrangement defining the coordination rules and procedures for the sharing of the bands 2000–2020 MHz and 2180–2200 MHz between Canadian and US licensees is under negotiation between Industry Canada, the Federal Communications Commission and the National Telecommunications and Information Administration. The Department anticipates that the resulting coordination procedures will include licensee‑to‑licensee coordination between AWS‑4 licensees in both countries, similar to how coordination in other AWS bands is already carried out.

The height of the antenna above average terrain (HAAT) is the height of the centre of radiation of the antenna above the average elevation of the terrain between 3 and 16 km from the antenna, for an individual radial. The final HAAT, also known as the effective height of the antenna above average terrain (EHAAT), is the average of the HAATs for 8 radials spaced every 45 degrees of azimuth starting with true north.
