1.  Intent

1.1  This Standard Radio System Plan (SRSP) sets out the minimum technical requirements for the efficient utilization of the band 1670-1675 MHz for fixed and mobile (except aeronautical mobile) services.

1.2  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

2.1  Equipment used for fixed and mobile (except aeronautical mobile) systems operating in the band 1670-1675 MHz must comply with RSS-112, Land Mobile and Fixed Equipment Operating in the Band 1670-1675 MHz.

2.2  Notwithstanding the fact that a system satisfies the requirements of this SRSP, the Department shall require adjustment to radio and auxiliary equipment in radio stations whenever harmful interferenceFootnote 1 is caused to any licensed radio station.

2.3   Radio systems conforming to these technical requirements will be given priority in licensing over non-standard radio systems operating in these bands. The arrangements for non-standard systems are outlined in Spectrum Utilization Policies Gen (SP-Gen), General Information Related to Spectrum Utilization and Radio Systems Policies.

2.4  Revisions to this SRSP will be made as required.

4.  Band Plan

4.1  The band 1670-1675 MHz is a single frequency block of 5 MHz and can be used for fixed and mobile (except aeronautical mobile) services.

4.1.1  Operators may employ frequency division duplexing (FDDFootnote 2) or time division duplexing (TDDFootnote 3) techniques in the band referred to in section 4.1. If FDD is employed, radio systems may use this block paired with another block of spectrum authorized by a spectrum licence. In this case, the block 1670-1675 MHz could be used for either mobile or base transmit operations.

If FDD is employed by pairing the 1670-1675 MHz block with another block of spectrum, each radio device shall comply with the relevant technical specifications (RSS and SRSP) for the frequency band in which the device is operating.

4.2  Usage of the band 1670-1675 MHz within the Canada/United States border area is subject to the provisions of the Sharing Arrangement Between the Department of Industry of Canada and the Federal Communications Commission of the United States of America Concerning the Use of the Frequency Band 1670-1675 MHz by Fixed and Mobile (except aeronautical mobile) Along the Canada-United States Border.

5.  Technical Criteria

5.1  Radiated Power

5.1.1  Fixed and Base Stations

Fixed and base stations operating in this band are limited to 2000 watts equivalent isotropically radiated power (e.i.r.p.) peak power.

5.1.2  Mobile Stations

Mobile stations are limited to 4 watts e.i.r.p. peak power.

6.  General Guidelines for Co-existence of Systems Operating in Same Blocks and in Adjacent Areas

In the event that a system using the same frequency block is authorized to different operators in adjacent service areas, coordination of any transmitter installations that are close to the boundary shall eliminate any harmful interference that might otherwise exist and ensure continuance of equal access to the frequency block by both operators.

For the purpose of protecting stations operating in adjacent service areas from co-channel interference, a base station shall not generate a power flux density exceeding -106 dBW/m2 in any 1 MHz bandwidth outside the operator's service area unless agreed otherwise by the affected operator.

Possible interference conflicts resulting from the operation of two 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, whereupon following consultations with the parties concerned, the Department will determine the necessary course of action.

System expansion measures such as addition of cells, cell splitting and sectorizationwill not force major changes in the system of the other operator, except by mutual agreement between the affected parties. Changes that would have potential impact, 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 Blocks

Out-of-block emission limits within the band 1670-1675 MHz are specified in RSS-112.

Possible interference conflicts resulting from the operation of two systems operating in adjacent blocks may occur even though the technical specifications of both this SRSP and RSS-112 are met.

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, the Department shall be so advised, whereupon following consultations with the parties concerned, it will determine the necessary modifications and/or schedule of modifications.

8.  Co-existence with Radio Systems in Adjacent Bands

Coordination may be required with licensees in adjacent bands. In this context, coordination involves consultation between operators to ensure the co-existence between systems in adjacent bands. Licensees should consult Industry Canada for the most up-to-date list of operators in the area.

Possible interference conflicts resulting from the operation of systems in the band 1670-1675 MHz and radio systems in adjacent bands 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 in a timely fashion, the Department shall be so advised, whereupon following consultations with the parties concerned, the Department will determine the necessary course of action.

8.1  Radio Systems Operating Above 1675 MHz

It should be noted that the meteorological aids systems operate in the band 1675-1685 MHz and meteorological satellite (space-to-Earth) services operate in the band 1675-1700 MHz.

8.1.1  Meteorological Satellite

Licensees in the band 1670-1675 MHz will be required to coordinate with existing licensed facilities of the meteorological satellite service.

8.2  Radio Systems Operating Below 1670 MHz

8.2.1  Radio Astronomy Service

It should be noted that the radio astronomy service operates in the band 1668.5-1670 MHz. This band is used by the Dominion Radio Astrophysical Observatory near Penticton, British Columbia. Licensees will be required to protect the radio astronomy service in this area.

For the purpose of this SRSP, harmful interference means interference which endangers the functioning of a radionavigation service or other safety services, or seriously degrades, obstructs, or repeatedly interrupts a radiocommunication service operating in accordance with regulations and technical requirements laid down by Industry Canada under the Radiocommunication Act.
