2. General

2.1 Revisions to this SRSP will be made as required.

2.2 Notwithstanding the fact that a system satisfies the requirements of this SRSP, Industry Canada may require adjustment to radio and auxiliary equipment in radio stations whenever harmful interferenceFootnote 2 is caused to any radio station or system.

2.3 When potential conflicts between systems cannot be resolved, the Department shall be so advised. Following consultation with the parties concerned, it will determine the necessary modifications and schedule of modifications.

2.4 Equipment operating in the above bands must comply with appropriate technical standards listed in paragraph 3.2.

2.5 Cellular telephone service is not intended to be provided to airborne mobile terminals.

2.6 New technologies can be introduced into cellular spectrum provided that the provisions of this standard are observed.

2.7 It is desirable to maintain connectivity if the mobile subscriber roams into a geographic area serviced under a different service provider.

2.8 Low-power devices to extend cellular features (e.g. wireless PBX using cellular RF channels) are permitted on the conditions that such usage is by or under the control of the cellular service provider, the integrity of the public cellular service is maintained, and equipment is certified and meets the appropriate approval standard(s).

2.9 Licensees will be expected to respect the understanding and arrangement established with the United States of America pertaining to these bands and abide by any future arrangements/agreements.

2.10 It should be noted that the mobile terrestrial service shares these bands with other services in accordance with the Canadian Table of Frequency Allocations and the International Telecommunication Union's (ITU) Radio Regulations.

5. Technical Criteria

5.1 Power and Antenna Height Limitations

5.1.1 Base stations for digital systems are limited to 1640 watts maximum equivalent isotropically radiated power (EIRP) with an antenna height above average terrain (HAAT) up to 150 m, except in urban areasFootnote 3 where they are limited to a maximum allowable EIRP of 820 watts.

5.1.2 Base stations for analogue systems are limited to 820 watts maximum EIRP with an antenna height above average terrain (HAAT) up to 150 m, except in urban areas where they are limited to a maximum allowable EIRP of 164 watts.

5.1.3 The maximum EIRP shall be 11.5 watts for mobile stations.

5.1.4 The EIRP and antenna height shall be limited to that necessary to provide the required service as governed by the system requirements.

5.1.5 A reduction in EIRP from that specified in paragraphs 5.1.1 and 5.1.2 is required for base stations with antenna height above average terrain (HAAT) in excess of 150 m as follows:

EIRPreduction= 20log10HAAT/150

In the above formula, the EIRP reduction is measured in dB and the HAAT is measured in metres.

5.2 Out-of-band Emission Limits

5.2.1 Out-of-band emission limits are specified in RSS-118, RSS-129 and RSS-132.

6. General Guidelines for Co-existence of Systems Operating in the Same Sub-bands

In the event that a cellular system is authorized to use the same frequency block used by different operators in adjacent service areas, coordination of any transmitter installations which are within 70 km of the boundary shall be required, except for installations with EIRP exceeding 500W less the HAAT correction indicated in paragraph 5.1.5, for which the coordination distance is 121 km. This is to eliminate any harmful interference that might otherwise be present and to ensure continuance of equal access to the frequency block by both operators.

The reliable service area of cells is defined to be 35 dB µV/m at the cell perimeter. For the purpose of protecting stations operating in adjacent service areas from co-channel interference, a base station shall not generate a field strength exceeding this level outside the operator' service area unless agreed otherwise by the affected operator.

Possible interference conflicts resulting from the operation of two cellular systems may occur. The resolution of those conflicts should be through mutual arrangements between the affected parties following consultation and coordination.

When potential conflicts between systems cannot be resolved, Industry Canada shall be so advised. Following consultations with the parties concerned, the Department will determine the necessary course of actions.

System expansion measures such as addition of cells, cell splitting and sectorization will not force major changes in the system of the other operator, except by mutual agreement between the affected parties. Any changes, including cell site locations, cell sectorization and cell splitting, require consultation with the other operator.

7. General Guidelines for Co-existence of Systems Operating in Adjacent Sub-bands

Possible interference conflicts resulting from the operation of two systems operating in adjacent sub-bands may occur even though the technical specifications of this SRSP and of RSS-118, RSS-129 and RSS-132 are met.

The resolution of those conflicts should be through mutual arrangements between the affected parties following extensive consultation and coordination.

When potential conflicts between systems cannot be resolved, Industry Canada shall be so advised. Following consultations with the parties concerned, the Department will determine the necessary modifications and schedule of modifications.

8. Co-existence with Radio Systems in Adjacent Bands

8.1 Broadcast Systems Operating Below 806 MHz

It should be noted that television broadcasting undertakings operate below 806 MHz in accordance with BPR-4 or BPR-7.

Base stations of cellular systems in the band 869-894 MHz can cause degradation to TV reception for certain older receivers when tuned to TV channels 65, 66, 67, 68 and 69, due to high signal strength from base station signals that are image-related to the TV channels. The relationship between cellular base transmit band and UHF TV image responses is shown in Figure 2.

Figure 2: Relationship Between Cellular Base Transmit Band and UHF TV Image Response
Relationship Between Cellular Base Transmit Band and UHF TV Image Response

[Description of Figure]

Figure 2: Relationship Between Cellular Base Transmit Band and UHF TV Image Response

Cellular system providers will take prudent measures to ensure that interference does not occur. This will include consultation with the appropriate Industry Canada office when planning base station sites within the Grade B contour for the TV stations listed in the DTV (Digital Television) Transition Allotment Plan.

Should interference problems arise in spite of the precautionary measures, the cellular system provider will take reasonable steps, including the possible installation of "image filters," for the affected TV receivers, to arrive at a mutually satisfactory resolution with TV receiver owners.

8.2 Mobile Radio Systems Operating Below 824 MHz and 869 MHz

It should be noted that public safety mobile radio systems operate below 824 MHz and 869 MHz in accordance with SRSP-502. Coordination may be required with these systems for the protection of base station receivers operating in the lower part of the sub-bands.

Appendix A —  RF Channel Designation For Analogue Cellular Systems

The RF channel designations for analogue cellular systems are shown in Tables A and B. Different channel bandwidths are permitted for digital services.

top of page

1. Sub-band A

The RF channels of the sub-band A are subdivided into two groups as outlined in the following paragraphs.

1.1 Analogue Traffic Channels

The RF channels in the two sub-bands 824.040-834.360 MHz and 845.010-846.480 MHz paired with the two consecutive sub-bands (869.040-879.360 MHz and 890.010-891.480 MHz) are available for use as traffic channels. Traffic channels may be used for either speech or data transmission provided that such data use will not reduce overall spectrum efficiency.

1.2 Analogue Control Channels/Access Channels

The analogue control channel is used for the transmission of digital control information for analogue systems. A total of 21 control/access channel pairs are assigned in sub-band A. The 21 channel pairs are 834.390 MHz to 834.990 MHz paired with 879.390 MHz to 879.990 MHz. Additional control/access channels may be designated where required.

2. Sub-band B

The RF channels of the sub-band B are subdivided into two groups as indicated in the following paragraphs.

2.1 Analogue Traffic Channels

The RF channels in the two sub-bands 835.650-844.980 MHz and 846.510-848.970 MHz paired with the two consecutive sub-bands (880.650-889.980 MHz and 891.510-893.970 MHz) are available for use as traffic channels. Traffic channels may be used for either speech or data transmission provided that such data use will not reduce overall spectrum efficiency.

2.2 Analogue Control/Access Channels

The analogue control channel is used for the transmission of digital control information for analogue systems. A total of 21 control/access channel pairs are assigned in sub-band B. The 21 channel pairs are 835.020 MHz to 835.620 MHz paired with 880.020 MHz to 880.620 MHz. Additional control/access channels may be designated where required.

3. Coordination of Adjacent Control/Access and Traffic Channels in Systems A and B

Analogue cellular telephone systems using adjacent frequency blocks shall require coordination of control/access channels 333 and 334, as well as traffic channels 666, 667, 716 and 717. An arrangement has been made between cellular systems providers regarding the usage of channel 355 as a control/access channel in place of channel 334 in order to minimize interference potential.
