Confirmation of Acceptance

The attached document is the interim sharing arrangement between the Federal Communications Commission and the Department of Industry (Industry Canada) concerning the use of the frequency bands 2305-2320 MHz and 2345-2360 MHz by stations in the Wireless Communications Service (WCS) near the Canada/United States of America border. The Federal Communications Commission and Industry Canada intend to implement provisionally the attached arrangement, to the extent permissible under their respective domestic laws, until superseded by a replacement for the Agreement Concerning the Coordination and Use of Radio Frequencies Above Thirty Megacycles per Second, with Annex, as amended Footnote 1, or other relevant agreements.

1.  Scope

1.1  This interim arrangement (Arrangement) between the Federal Communications Commission (FCC) of the United States of America (U.S.) and the Department of Industry (Industry Canada) of Canada (jointly, the Administrations) concerns the use of the frequency bands 2305 – 2320 MHz and 2345 – 2360 MHz by WCS systems within 120 km of the Canada/United States of America Border. This Arrangement applies to stations of WCSin the fixed and mobile (except aeronautical) services; it does not apply to the digital audio radio service (DARS) by satellite nor its terrestrial repeater applications.

1.2  This Arrangement will be applied provisionally until superceded by a replacement for the Agreement Concerning the Coordination and Use of Radio Frequencies Above Thirty Megacycles per Second, with Annex, as amended Footnote 2 or other relevant agreements.

1.3  This Arrangement is subject to review at any time at the request of either Administration.

2.  General Principles

2.1  The bands 2305-2320 MHz and 2345-2360 MHz are to be shared on an equal basis along the border and, to the extent possible, both Administrations shall have full use of these frequencies or sub-bands for the provision of WCS within their respective countries.

2.2  Coordination shall be carried out by the WCS licensees for their respective service areas on both sides of the border.

2.3  Licensees are encouraged to enter into mutually acceptable sharing agreements that will facilitate reasonable and timely development of their systems. These agreements should allow for the provision of services by each licensee within its licensed service area to the maximum extent possible and provide for the basis of coordination in the border area.

2.4  Licensees are expected to take full advantage of interference mitigation techniques such as antenna directivity, polarization, frequency offset, shielding, site selection and/or power control to facilitate the coordination of systems.

2.5  All data and calculations used in determining compliance with this Arrangement and/or licensee sharing agreements shall be retained by the licensees and be made available to the Administrations upon request.

2.6  If a license is transferred, assigned or reissued, any existing agreement that formed the basis of coordination in the border area shall continue to apply with respect to the new licensee unless a new agreement is reached.

2.7  When licensees are unable to conclude mutually acceptable sharing arrangements, Section 3 of this Arrangement will apply.

3.  Cross-Border Coordination Between Licensed WCS Operators

3.1  The stations that are to be considered for coordination under this section of this Arrangement are the base stations (central transmitting stations) and their associated subscriber stations, and shall be referred to jointly as WCS systems. Additional coordination is required with respect to specified fixed microwave stations pursuant to Section 4 of this Arrangement.

3.2  Coordination of a WCS station is required if: 

  1. it is located at a distance less than 120 km from the U.S./Canada border; and
  2. it would produce at ground level in the other country's territory a power flux-density (pfd) level greater than -110 dB(W/m2) in any 1 MHz bandwidth.Footnote 3

3.3  When coordination is required, the following procedures shall apply : 

3.3.1  The licensee seeking coordination shall determine the maximum pfd value at and beyond the border that could be produced by any single transmitting station of the WCS system. In making this determination (calculation) the licensee shall use good engineering practice and generally accepted terrain-sensitive propagation models. The licensee shall disclose, upon request by the Administration, all data and calculations used in determining compliance with this Arrangement.

3.3.2  The recipient of the coordination proposal must respond by registered mail (or other mutually acceptable method) within 30 days of receipt to indicate any objection to deployment of the proposed facilities. If no objection is raised within that timeframe, then deployment of facilities may proceed.

3.3.3  If an objection is raised by the recipient of the coordination proposal, licensees must work in collaboration to develop a mutually acceptable solution to the potential interference problem. It is expected that the time from the date of the objection to develop and reach agreement on such a solution should not exceed 30 days.

3.3.4  In the event that a mutually acceptable agreement cannot be concluded between licensees, then the licensee seeking coordination may ask its Administration to facilitate resolution of the case with the other Administration. A station that requires coordination shall not be placed in operation until an agreement has been reached or until both Administrations concur and authorization by the appropriate Administration has been provided.

3.3.5  If there is no licensee on the opposite side of the border, any station of the proposed system shall not produce a pfd at or beyond the border that exceeds -110 dB(W/m2) in any 1 MHz bandwidth. Exceeding the pfd in this case would require the agreement of both Administrations.

3.4  Any WCS station will require further coordination if proposed modifications would : 

  1. result in the pfdat or beyond the border exceeding -110 dB(W/m2) in any 1 MHz bandwidth;
  2. involve operation on frequencies not previously coordinated; or
  3. change the polarization.

4. Coordination with Existing Fixed Microwave Stations

4.1  Licensees of WCS systems with stations located within 120 km of existing fixed microwave stations that have been authorized by the other Administration prior to the date of this Arrangement are required to coordinate with licensees of such fixed microwave stations if the WCS station would produce a pfd exceeding 110 dB(W/m2) in any 1 MHz bandwidth at or beyond the border (see Annex A).

4.2  Such coordination shall be based on : 

  • A technical analysis showing that interference is not caused to existing fixed microwave operations of the other Administration. The analysis shall be based on recognized industry procedures such as TIA/EIA Telecommunications Bulletin (TSB10-F), Interference Criteria for Microwave Systems;
    or
  • Alternatively, a mutually acceptable arrangement between the applicant/operator of the WCS facility and the affected fixed microwave operator(s).

4.3  In the event that a WCS station causes interference to an existing fixed microwave station located at a distance greater than 120 km from a WCS station, both Administrations agree to take immediate, appropriate steps to resolve such interference.

4.4  Administrations that have authorized fixed microwave stations will take steps to include a transition process through domestic policy that will facilitate the introduction of WCS in both countries.

5. Information Exchange

5.1  The Administrations will exchange licensee names, their licensed areas and points of contact to allow the licensees to contact the relevant licensee(s) on the other side of the border in order to facilitate licensee-to-licensee coordination in accordance with this Arrangement.

5.2  To facilitate cross-border coordination between licensees, the licensees are encouraged to exchange data as listed in Annex B to this Arrangement.

Parameters for Coordination

List of parameters that should be provided: 

  • Licensee information (Corporate name/Mailing address/Phone/Fax);

  • Geographical coordinates of transmitting antenna;
  • EIRP(dBW);
  • Ground elevation and antenna height above ground (m);
  • Centre frequency (MHz);
