1. Intent

This Standard radio system plan (SRSP) states the minimum technical requirements for the efficient spectrum utilization of land mobile and fixed point-to-point systems operating in the bands 406.1-430 MHz and 450-470 MHz.

Existing mobile systems that operate in areas of intensive mobile useFootnote 1 are considered to be non‑standard if they do not conform to Phase 1 and Phase 2 of Redeployment plan RDP 100‑500 MHz, Redeployment Plan for Spectrum Efficient Land Mobile Equipment in the Frequency Range 100‑500 MHz (referred to hereinafter as Redeployment plan) and the related criteria of those phases described in this SRSP.

Radio systems conforming to the requirements contained in this SRSP will take priority in licensing and coordination over non-standard systems proposed for operation in these bands, subject to the terms and conditions of Spectrum utilization policy SP Gen, General Information Related to Spectrum Utilization and Radio Systems Policies and the Redeployment plan. Systems will begin deletionnotend deletion be declared non-standard if they do not meet the paired or single frequency plan established in figures A1 to A3 of annex A.

Modification of a non-standard system will not be required except where this system blocks the entry of standard systems into the frequency bands covered by the Redeployment plan. Any system identified for modification under the provisions of the Redeployment plan will be required to conform to this SRSP, as stated above, and where spectrum availability permits.

2. General

Equipment used for land mobile or fixed systems operating in the above bands must normally comply with appropriate technical standards listed in section 3.

Notwithstanding the fact that a system satisfies the requirements of this standard, the Department shall require adjustment to radio and auxiliary equipment in radio stations whenever harmful interferenceFootnote 2 is caused to any radio station operating in accordance with departmental regulations or standards.

Systems licensed prior to August 12, 2001Footnote 3 that do not meet the requirements of this SRSP will be reviewed on a case-by-case basis. The systems may continue to be licensed on their existing frequencies as long as the non-standard aspects of these systems do not prevent or restrict the entry of a new licenced system which conforms to the standards of this SRSP. The expansion of licensed systems should proceed within the framework of the requirements of this Standard and, if radio equipment replacement is affected, conformity to this SRSP shall be required.

The Redeployment plan will take place in two phases which will require a transition to more spectrum-efficient land mobile equipment to free up more mobile spectrum in areas of Intensive Mobile Use where additional mobile uses cannot be accommodated. In Phase begin deletionIend deletionbegin insert1end insert , equipment must be capable of using less than 12.5 kHz bandwidth per voice channel in a 12.5 kHz channel spacing, and in Phase begin deletionIIend deletion begin insert2end insertend insert , equipment must be capable of using less than 6.25 kHz bandwidth per voice channel in a 6.25 kHz channel spacing.

The Department will provide protection to licensed radio receivers only to the extent of the bandwidth of the transmitters whose emissions they are receiving up to the limits of the channel assigned. Applicants should bear this in mind when selecting receivers and receiver filters.

Editor’s note

In August 2013, Industry Canada (hereinafter the “Department”) and the Federal Communication Commission (FCC) signed a Statement of Intent (SOI) with regards to the use of portions of the 450 MHz band. This SOI should be taken into consideration when licensing in this band.

3. Related documents

Equipment and systems to be used in the bands covered by this document shall be in accordance with the currently adopted versions of the following documents which are available on the Department’s Official publications page:

4. General guidelines

Frequency assignments shall be in accordance with figures A1 to A3 of annex A and the tables of annex B. The preferred type of usage is the paired frequency system except for those sub-bands designated for single frequency use. The base station transmitting frequencies and corresponding mobile station transmitting frequencies are illustrated in the above cited figures.

For land mobile service, channels shall be spaced 25 kHz, 12.5 kHz or 6.25 kHz apart. Series A, B and C are the designated centre frequencies for the 406.1-430 MHz band and series D, E and F are for the 450-470 MHz band.

The centre frequencies of each series can be determined by the following formulas:

For 406.1 - 430 MHz:

An = 406.1 + 0.01250 + (n–1) * (0.02500) MHz for 1≤n≤956
Bn = 406.1 + 0.01250 + (n–1) * (0.01250) MHz for 1≤n≤1912
Cn = 406.1 + 0.00625 + (n–1) * (0.00625) MHz for 1≤n≤3824

For 450 - 470 MHz:

Dn = 450.0 + 0.01250 + (n–1) * (0.02500) MHz for 1≤n≤800
En = 450.0 + 0.01250 + (n–1) * (0.01250) MHz for 1≤n≤1600
Fn = 450.0 + 0.00625 + (n–1) * (0.00625) MHz for 1≤n≤3200

The following frequency channels in series B, C, E and F should be considered last for assignment in order to preserve backward compatibility with the existing 25 kHz channelling plans:

Series F F160 F484 F640 F804 F960 F1284 F1440 F1604 F2244 F2404 F3044

Interstitial 25 kHz spacing channels spaced 12.5 kHz from the main A and D channels may be assignable in certain bands and where the radio system is located outside Intensive Mobile Use areas.

4.1 Very low capacity fixed links in the 400 MHz bandFootnote 4

The licensing of very low capacity fixed links in the bands below 890 MHz is governed by Radio systems policy-004. Fixed links will be assigned on a primary basis in the sub-bands 414‑415 MHz and 419-420 MHz (Duplex Block B, see section 5.4) and may be assigned on a secondary non‑interference basis with respect to land mobile services in the other sub-bands included in this SRSP, except as stipulated under the provisions of RP-013.

The maximum number of RF channels (frequencies) assignable will depend on the nature of the service and the geographic location of the proposed fixed system as described in the Radio Systems Policy RP‑004, Policy for the Licensing of Very Low Capacity Point to Point Links in the Band 30-890 MHz.

Systems having up to 6 multiplexed voice channels and a total necessary bandwidth of not more than 90 kHz in each direction may be authorized in areas of light mobile use.

Systems requiring more than 6 multiplexed voice channels and bandwidths in excess of 90 kHz in each direction are not normally assignable except on a special case basis.

Fixed system equipment with a necessary bandwidth greater than 16 kHz (greater than a voice channel) must be certified in accordance with the requirements of section 1.4 and appendix B of Radio standard procedure-101.

Single frequency operation utilizing the base/repeater transmit frequency (known as talk around) beyond the service area of a paired frequency system may be permitted on a case by-case basis as an adjunct to the paired frequency system. Such operation may be permitted within the authorized service area at the discretion of the system operator and will be on a non-interference basis to the other users in the case of a service provider in the land mobile service.

Licensing of systems that employ a base station as an automatic repeater is permitted. Automatic repeater stations shall transmit on frequencies identified as base transmit frequencies. Subscriber dispatch stations (often referred to as control stations) shall transmit on frequencies identified as mobile frequencies.

One way communication systems are permitted. In bands indicated for single frequency use, one-way systems will be given the same priority as two-way systems.

5. Availability of spectrum and sub-allocation

5.1 Arrangements with the United States of AmericaFootnote 5

In order to meet the requirements of the radio services in both Canada and United States, the administrations have established arrangements for the exchange of frequency assignment information and engineering comments of proposed assignments along the Canada/United States borders. In addition, for the interests of equitable sharing of spectrum and to reduce coordination and administrative effort and time, the governments of Canada and the United States have also entered into arrangements whereby certain portions of the band 421-430 MHz are set aside on a block allocation basis for the unrestricted geographic use of either country in border areas. The terms of these arrangements take into account the demographic differences that exist along the border between the two countries, that is, the country with the larger population in a given geographic area receives the larger share of the available spectrum for its use in that area. A country making an assignment within a block allocated to that country is not normally required to coordinate that assignment with the other country. The coordination and use of the frequency band 406.1-430 MHz is governed by Arrangement E, Arrangement between the Department of Communications of Canada and the National Telecommunications and Information Administration and the Federal Communications Commission of the United States Concerning the Use of the 406.1 MHz to 430 MHz Band in Canada-United States Border Areas while the coordination and use of the frequency band 450-470 MHz is governed by Arrangement A, Arrangement between the Department of Transport and the Federal Communications Commission for the Exchange of Frequency Assignment Information and Engineering Comments on Proposed Assignments along the Canada-United States borders in certain bands above 30 mc/s. Outside the border areas, there are no restrictions on either country. However when a possibility exists that assignments outside the border areas may result in harmful interference to the radio services of the other country, special coordination process will be initiated.

The band 420-430 MHz is shared between the Canadian fixed and mobile services and the U.S. radiolocation services in the border area. The fixed and mobile services may be disrupted in certain areas of Canada by interference from U.S. radiolocation services during periods of emergency. For this reason, safety services users with fixed and mobile radio service requirements should not utilize the band 420-430 MHz if they are unable to tolerate disruption during those periods of emergency. Those considering the use of this band should consult with the Department's regional office in their area.

The use of band 406.1-430 MHz will require coordination with the U.S. in the coordination zone, outlined in figure A4, and the use of the band 450-470 MHz will require coordination with the U.S. in the coordination zone outlined in Arrangement A.

The bands 409-410 MHz and 420-421 MHz (Duplex Block A, see section 5) are available for use in Canada on an unrestricted basis in the border areas. However, it should be noted that the U.S. may coordinate assignments within the coordination zone on a case-by-case basis.

5.2 Sub-allocation channelling plan for the bands 406.1-410 MHz and 420-430 MHz

A sub-allocation channelling plan is outlined below, including national sub-allocations. Frequency assignments will begin 12.5 kHz above the lower band edge for the 25 kHz and 12.5 kHz channel spacing plans, and 6.25 kHz from the lower band edge for the 6.25 kHz channel spacing plan. The detailed geographic availability and sub‑allocation channelling plan for these bands are illustrated in figures A1 and A2.

Portions of the available spectrum in the bands 406.1-410 MHz and 420-430 MHz which are not specifically designated for particular purposes are assignable for appropriate uses on a regional or local consideration.

For Simplex Block A, the band 406.1-409 MHz is sub-allocated for single frequency operation.

For Duplex Block D, the band 421-425 MHz paired with 426-430 MHz are sub-allocated for two-frequency operation.  The base station transmitting frequencies are in the band 421‑425 MHz while the corresponding mobile station transmitting frequencies are in the band 426‑430 MHz. The spacing between associated mobile and base station frequencies in the 421‑425/426‑430 MHz bands is normally 5 MHz.

On regional or local considerations, short spaced paired assignments may be made in the band 406.1-409 (Simplex Block A) to meet spectrum demands.

National paired frequency systems

The band 421.000-422.175 MHz paired with 426.000-427.175 MHz is sub-allocated for national land mobile radio systemsFootnote 6. This will provide a total of 47 primary paired frequency channels of 25 kHz spacing, a total of 93 primary paired frequency channels of 12.5 kHz spacing or a total of 187 primary paired frequency channels of 6.25 kHz spacing which will be reserved for users with national requirements.

National single frequency systems

For Simplex Block B, the band 425.500-426.000 MHz is sub-allocated for national land mobile radio systems for single frequency operation. This band will provide a total of 20 channels of 25 kHz spacing, a total of 39 primary frequency channels of 12.5 kHz spacing, or a total of 79 primary frequency channels of 6.25 kHz spacing which will be reserved for users with national requirements.

Trunked mobile radio systems

A trunked mobile radio system is one in which the communications traffic may pass through any one of the "trunked groups of channels" selected automatically by the system. The bands 422.175-422.675 MHz and 427.175-427.675 MHz are sub-allocated for trunked radio systems employing up to five channels per group with a 50 kHz spacing between channels of the same trunked group.

Conventional mobile radio systems

Assignments for conventional systems may be made from the available spectrum in a given area and in accordance with RDP 100-500. In general, assignments will be made commencing at the upper end and working downward.

5.3 Sub-allocation channelling plan for the bands 409-410 MHz and 420-421 MHz

For Duplex Block A, the band 409-410 MHz paired with 420-421 MHz is sub-allocated for two‑frequency operation providing 40 primary paired frequency channels of 25 kHz spacing, 79 primary paired frequency channels of 12.5 kHz spacing, or 159 primary paired frequency channels of 6.25 kHz spacing depending on the geographical location. The base station transmitting frequencies are in the band 420-421 MHz while the corresponding mobile station transmitting frequencies are in the band 409-410 MHz. The spacing between associated mobile and base station frequencies in the 409-410/420-421 MHz bands is normally 11 MHz.

Duplex Block A, currently allocated for use by medium capacity mobile radiotelephone services, is additionally allocated to mobile radio dispatch services under Spectrum Utilization Policy SP-450 MHz, Spectrum Utilization Policy for the Frequency Bands 450-451 MHz and 455-456 MHz and also Part of the 150 MHz Band Used in Support of Broadcasting Operations and the Frequency Band 409-410 MHz and 420-421 MHz Used by the Mobile Radio Service. Details on the application of the policy are provided in the policy itself and in RP‑013, Spectrum Utilization Policy on the Use of Certain Public Correspondence Bands in Canada (GLMRS).

On regional or local considerations, Duplex Block A may be assigned for trunked radio systems (see definition in section 5), based on a 100 kHz spacing between channels of the same trunked group.

5.4 Sub-allocation channelling plan for the bands 410-420 MHz and 450-470 MHz

For Duplex Block C, the band 410-begin deletion420end deletionbegin insert419end insert MHz is sub-allocated as outlined below and is illustrated in figure A1. The sub-band 410-414 MHz paired with 415-419 MHz is sub-allocated for two frequency mobile radio operations with the base station transmitting in the 410‑414 MHz band and the mobile station transmitting in the 415-419 MHz band. The spacing between associated mobile and base stations is normally 5 MHz.

On regional or local considerations, frequencies in the sub-bands 413-414 MHz and 418-419 MHz may be assigned to single frequency operations.

For Duplex Block B, the sub-band 414-415 MHz paired with 419-420 MHz is allocated on a primary basis to fixed systems. Mobile radio services may be assigned on a secondary basis as per section 4.1 and are subject to RDP 100-500 MHz. The spacing between associated mobile and base stations is normally 5 MHz with the mobile station transmitting in the band 419‑420 MHz.

The band 450-470 MHz is available to mobile radio services on a primary basis, except as indicated otherwise. The detailed sub-allocation plan for this band is illustrated in figure A3.

For Simplex Blocks C, D, E and F, the sub-bands 453.025-454 MHz, 458.025-459 MHz, 464.025-465.025 MHz and 469.025-470 MHz are sub-allocated for single frequency operations, respectively.

For Duplex Blocks E, F and G, the sub-bands 451-453.025 MHz paired with 456-458.025 MHz, 460.025-464.025 MHz paired with 465.025-469.025 MHz and 454.0-455.025 MHz paired with 459-460.025MHz are sub-allocated for two-frequency operations, respectively. The spacing between associated mobile and base station frequencies is normally 5 MHz with the mobile station in the upper frequency sub‑bands.

Utilization of the sub-bands 450-451 MHz and 455-456 MHz

The sub-bands 450-451 MHz and 455.025-456 MHz are allocated for land mobile services to support broadcast undertakings in accordance with the SP-450 MHz. These frequencies may be available for assignments to general land mobile services under the discretion of the district Director and in accordance with the current SRSP.

On regional or local considerations, land mobile services that operate with larger bandwidth to support broadcasting undertakings may be assigned, provided that radio equipment is certified, in accordance with RSP-101, Licence Application Submission Procedure for Planned Radio Stations Below 960 MHz.

Railway frequency in the 452.9000 - 452.9500 MHz and 457.9000 - 457.9500 MHz bands

Although these bands are included in this SRSP and in RDP 100-500 MHz, they are assigned to the railways and are not subject to the channelling plans prescribed in this SRSP. These bands are assigned by means of a spectrum licence to the Railway Association of Canada on an exclusive basis within the geographical area consisting of a corridor bounded 70 km on each side of railway lines.

Beyond this geographical area, railway frequencies may be available for assignment to land mobile services according to this SRSP and provided that the railway service is protected within the railway’s geographical area of operation.

Frequencies designated for family radio service (FRS) and General mobile radio service (GMRS) use

The Department issued Gazette Notice DGTP-004-00 on March 31, 2000 and DGTP-001-04 on March 27, 2004, allowing the use of FRS devices and GMRS devices at the frequencies listed in table 1. A moratorium on any further licensing of the frequencies, as shown in table 1, to new land mobile systems is therefore in effect.

Editor’s note

In August 2016, the Department released Spectrum Utilization Policy SP 462/467 MHz, issue 2, Spectrum Utilization Policy to Permit Licence-Exempt Devices in the Land Mobile Frequency Sub-bands 462/467 MHz, which establishes provisions to allow the operation of GMRS-M devices in the 462 MHz band. GMRS-M devices have similar technical specifications to existing GMRS devices, but provide for different applications, including dog tracking devices, pet containment units and intercom systems. These devices are permitted to operate on a licence‑exempt basis on specific frequencies in the 462 MHz frequency range. For the five designated GMRS-M frequencies, refer to SP 462/467 MHz.

6. Technical considerations

6.1 Channel sharing

Section 40 of the Radiocommunication Regulations states: "The assignment of a frequency or frequencies to a holder of a radio authorization does not confer a monopoly on the use of the frequency or frequencies, nor shall a radio authorization be construed as conferring any right of continuing tenure in respect of the frequency or frequencies".

6.2 Loading guidelines

Normally, the Department will apply the guidelines found in GL-begin deletion0end deletion04, Channel Loading Guidelines in determining loading of communications channels, and thus, of radio channels.

In the frequency assignment process, these guidelines may be utilized in conjunction with current observed channel occupancy data (obtained with automatic occupancy measuring equipment) to determine whether additional channels are required. Such observations will also be used to assess the general loading criteria and the inherent trade-off between sound spectrum management and acceptable grades of service.

The Department is using this approach to make frequency assignments but may also take into account other consideration when determining the number of radio channels to be assigned to a system. Applicants are encouraged to provide as much traffic related data as possible with their application.

6.3 Radiated power limits for mobile systems

Normally for base stations the maximum effective radiated power (ERP) shall be 125 watts. However, in all cases, the ERP shall be limited to that necessary to provide a balanced radio system (talk-back facility) over the desired service area or the required level of service as governed by the system requirements.

6.4 Radiated power limits for fixed point-to-point systems

Unless otherwise justified, fixed point-to-point systems must use directional antennas with a minimum gain of 9 dB with respect to a half-wave dipole. Antennas horizontally polarized must be used in all cases unless operational requirements justify vertical polarization.

The maximum ERP shall be limited to that which is required to achieve system reliability requirements and shall not exceed 125 watts.

6.5 Co-channel assignmentsFootnote 7

Applications for dedicated channels are invited to include adequate technical details in support of their proposed wireless networks to allow a compatibility analysis with existing and future assignments. These details should include, but not be limited to, the required service area, the predicted radio coverage, and the design parameters used including the minimum carrier to interference (C/I) ratio.
