Arrangement F

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 Bands 806-824 MHz and 851-869 MHz by the Land Mobile Service Along the Canada-United States Border

The Department of Industry of Canada (Industry Canada), and the Federal Communications Commission of the United States of America (FCC), hereinafter referred to as the “Agencies”,

Have agreed to the following:

1. Scope

1.1 This Arrangement is made pursuant to the Exchange of Notes (October 24, 1962) between the Government of Canada and the Government of the United States of America concerning the coordination and use of radio frequencies above thirty megacycles per second, with annex, completed at Ottawa October 24, 1962, as amended, and covers the sharing and coordination of frequency spectrum for the establishment and operation of land mobile radio services operating in the bands 806 to 824 MHz, and 851 to 869 MHz, along the Canada-United States border.

1.2 Aeronautical and maritime mobile services in this band are not covered by this arrangement but may be subject to special coordination procedures on a case-by-case basis at the request of either Agency prior to their introduction.

1.3 The Agencies may initiate and implement special coordination allowing proposed stations to operate in a manner exceeding the technical conditions stated in this Arrangement within the sharing zones where the affected licensees agree to such conditions. Special coordination may be initiated by either Agency through an exchange of correspondence and must be approved by both Agencies.

1.4 This Arrangement is subject to review at any time at the request of either Agency, the U.S. Department of State or the Department of Foreign Affairs and International Trade Canada.

2. Sharing and Protection Zones

There are three Sharing Zones.

2.1 Sharing Zone I:

This Sharing Zone is the area adjacent to the United States-Canada border East of longitude 121°30' W and extending a distance of 100 km within either country. However, within Sharing Zone I, the following special geographic areas are recognized:

  • (a) In the Great Lakes area there are significant land areas that are within 100 km of the international border between the United States and Canada, but further than 100 km from any land mass of the other country. These areas contain several significant population centers that would benefit from additional spectrum if the lake shores were considered for purposes of sharing. With this in mind, the following cities shall be considered as falling outside of Sharing Zone I, but inside the Protection Zone: in the United States, the cities of Akron, Ohio; Youngstown, Ohio; Syracuse, New York; and in Canada, the cities of Kitchener-Waterloo, Ontario; Peterborough, Ontario; London, Ontario. These cities are defined in Annex A, Table A4 as an area with the given center coordinates and encompassing a circle of 30 km radius.
  • (b) Sector 1 and Sector 2 as defined in section 4 below are recognized as special geographic areas within Sharing Zone I.

2.2 Sharing Zone II:

This Sharing Zone is the area adjacent to the United States-Canada border between 121°30' and 127°W longitude and extending a distance of 140 km within either country.

2.3 Sharing Zone III:

This Sharing Zone is the area adjacent to the Alaska-British Columbia/Yukon Territory border and extending a distance of 100 km within either country.

2.4 Protection Zone:

The Protection Zones are the areas adjacent to Sharing Zones I and III and extending from 100 to 140 km away from the United States-Canada border within both countries as well as the areas defined in Annex A, Table A4.

3. General Sharing Arrangements

3.1 Paired Channeling Arrangements

Within the Sharing Zones and Protection Zones, the Agencies shall use the spectrum on the basis of a paired frequency channeling plan with mobile station transmitters in the band 806-824 MHz and base station transmitters in the band 851-869 MHz. A mobile station may also transmit on any frequency assigned to its associated base station. Base station to base station transmissions may occur in either of these frequency bands.

3.2 Distribution/Allotment of Frequencies

The frequency bands covered by the Arrangement are to be shared along the border, as indicated below (summarized in Annex B, Figure 1). Each Agency may use their allotted portions of spectrum subject to not causing harmful interference to assignments beyond the allotted frequency band edges and subject to the technical limits described in section 5.

3.2.4 Protection Zones

In the Protection Zones, each Agency has primary use of the frequency bands 806-824 MHz and 851-869 MHz.

3.3 Use of the 806-824 MHz, and 851-869 MHz Bands Outside of the Sharing and Protection Zones

Beyond 140 km from the border, the Agencies have primary use of these bands.

3.4 In the event that harmful interference is experienced, both Agencies shall take appropriate action to eliminate such interference.

4. Special Sharing Arrangements

In recognition of particular demographic circumstances, the Agencies agree on the unequal division of spectrum between Canada and the United States in the following two sectors of Sharing Zone I:

4.1 Sector 1:

Sector 1 is defined to be the portion of Sharing Zone I in the United States and Canada, bounded on the West by 85°W longitude and on the East in Canada by 81°W longitude and in the United States by 80° 30’ W longitude.

Within an area of 30 km radius from the centre city coordinates of London, Ontario, 42°59' N. 81°14' W., Canada has primary access as defined in section 2.1 (protection zone).

5. Technical Limits

5.1 Within Sharing Zones I (including Sectors 1 and 2) and III, the Agencies may use their allotted portions of spectrum subject to the Effective Radiated Power (ERP) and Effective Antenna Height (EAH) limits of Annex A, Table A1.

5.2 Within Sharing Zone II, the Agencies may use their allotted portions of spectrum subject to the Effective Radiated Power (ERP) and Antenna Height Above Mean Sea Level (AMSL) limits of Annex A, Table A2.

5.3 Each Agency has full use of the 806-824 MHz and 851-869 MHz bands within the Protection Zone in its respective country subject to the condition that base stations not exceed the maximum Effective Radiated Power (ERP) and Effective Antenna Height (EAH) limits of Annex A, Table A1.

5.4 Within the Sharing and Protection Zones, calculation of the limits on Effective Radiated Power (ERP) should be based on the power radiated toward the horizon in the vertical plane and should apply only in the direction of the common border.

5.5 Each Agency may authorize stations that exceed the ERP limits specified in sections 5.1 through 5.4 provided the signal from such a station does not exceed a maximum power flux density (pfd) limit of -107dB(W/m2)/25 kHz at and beyond the border and a maximum ERP of 500 watts in the direction of the common border. If the border falls over water the pfd limit shall apply at the shore beyond the border.

  • (a) The Agencies shall require applicants or licensees under this provision to calculate the pfd described in section 5.5 using good engineering practice and generally accepted terrain-sensitive propagation models (with location and time variables of 10% and standard 3 arc-second digitized terrain data). The Agencies shall provide all data and calculations for determining compliance with this Arrangement upon request.
  • (b) In the event that the actual pfd at or beyond the border exceeds the value described in section 5.5, it is the responsibility of the licensee to bring the station’s actual pfd into compliance with section 5.5 or bring the station into compliance with the power limits described in sections 5.1 through 5.4.

5.6 Assignments listed in Tables C1 and C2 of Annex C are exempt from the limits on ERP and antenna height detailed in Annex A. These assignments may continue operating at the indicated parameters but are prohibited from modification which would extend their existing 22 dBµV/m interference contour further in the direction of the common border.

6. Coordination Necessitated by the Special Sharing Arrangements

6.1 As a result of the division of spectrum described in sections 4.1 and 4.2, portions of the bands allotted to both countries under this Arrangement overlap. Therefore, the Agencies shall coordinate the proposed frequency assignments in the overlapping portions of those bands, as described in sections 6.2 and 6.3 below, in accordance with the procedures specified in Arrangement A annexed to the Agreement concerning the Coordination and Use of Radio Frequencies Above Thirty Megacycles per Second, as amended 24 June 1965.

6.2 Coordination is required for assignments in the frequency bands 808.2500 to 809.7500 MHz, 817.2500 to 818.7500 MHz, 822.5000 to 823.1000 MHz, 853.2500 to 854.7500 MHz, 862.2500 to 863.7500 MHz and 867.5000 to 868.1000 MHz in the following area (See Annex B, Figure 2):

  • (a) The geographical area in Canada enclosed by the United States-Canada border, the meridian 71ºW and the line beginning at the intersection of 72°W and the United States-Canada border, thence running North along meridian 72°W to the intersection of 45°45'N, thence running East along 45°45’N to the meridian 71°W, and
  • (b) the geographical area in the United States enclosed by the United States border, the meridian 71°W and the line beginning at the intersection of 44°25’N, 71°W, thence running by great circle arc to the intersection of 45°N, 70°W, thence North along meridian 70°W to the intersection of 45°45'N, thence running West along 45°45'N to the intersection of the United States-Canada border.

The Agencies shall assign channels in the overlapping bands on center frequencies spaced 25 kHz apart. The FCC shall assign frequencies from 808.2625 to 809.7375 MHz, 817.2625 to 818.7375 MHz, 822.5375 to 823.0875 MHz, 853.2625 to 854.7375 MHz, 862.2625 to 863.7375 MHz and 867.5375 to 868.0875 MHz inclusive. Industry Canada shall assign frequencies from 808.2750 to 809.7250 MHz, 817.2750 to 818.7250 MHz, 822.5500 to 823.0750 MHz, 853.2750 to 854.7250 MHz, 862.2750 to 863.7250 MHz and 867.5500 to 868.0750 MHz inclusive. The Agencies may agree to mutually beneficial changes to the above noted channeling plan in an effort to promote spectral efficiency.

6.3 Coordination is required for assignments in the frequency bands 808.2500 to 811.2500 MHz, 815.7500 to 818.7500 MHz, 821.4500 to 823.1000 MHz, 853.2500 to 856.2500 MHz, 860.7500 to 863.7500 MHz and 866.4500 to 868.1000 MHz in the following area (see Annex B, Figure 3):

  • (a) The geographical area in Canada enclosed by the meridian of 81°W longitude, the arc of a circle of 100 km radius centered at 41° 58’N latitude and 80° 30’W longitude at the southern shore of Lake Erie and drawn clockwise from the northerly intersection with 81°W longitude to intersect the United States-Canada border East of 80° 30’W, and the United States-Canada border, and
  • (b) the geographical area in the United States enclosed by the meridian of 81°W longitude, the arc of a circle of 100 km radius centered at 42° 39’30” N latitude and 81°W longitude at the northern shore of Lake Erie and drawn clockwise from the southerly intersection with 80º 30’W longitude to intersect the United States-Canada border West of 81°W, and the United States-Canada border.

The Agencies shall assign channels in the overlapping bands on center frequencies spaced 25 kHz apart. The FCC shall assign frequencies from 808.2625 to 811.2375 MHz, 815.7625 to 818.7375 MHz, 821.4625 to 823.0875 MHz, 853.2625 to 856.2375 MHz, 860.7625 to 863.7375 MHz and 866.4625 to 868.0875 MHz inclusive. Industry Canada shall assign frequencies from 808.2750 to 811.2250 MHz, 815.7750 to 818.7250 MHz, 821.4750 to 823.0750 MHz, 853.2750 to 856.2250 MHz, 860.7750 to 863.7250 MHz and 866.4750 to 868.0750 MHz inclusive. The Agencies may agree to mutually beneficial changes to the above noted channeling plan in an effort to promote spectral efficiency.

Within an area of 30 km radius from the centre city coordinates of London, Ontario, 42°59' N. 81°14' W., Canada has primary access as defined in section 2.1 (protection zone).

6.4 Canadian assignments listed in Table C3 of Annex C are granted protection against harmful interference from United States stations. These assignments may continue to operate at the indicated parameters but are subject to coordination if modifications are made which would extend their existing 22 dBµV/m interference contour further in the direction of the common border and exceed the technical limits described in section 5.

7. Use of Frequencies Allotted to One Administration by the Other Administration

7.1 Frequencies allotted for primary use of one Agency may be assigned by the other Agency for use within the sharing zones in its country under the following conditions:

  • (a) The maximum power flux density (pfd) of the signal at and beyond the border of the primary user’s country does not exceed -124 dB(W/m2)/25 kHz.
    • (1) The Agencies shall require applicants or licensees under this provision to calculate the pfd described in section 7.1(a) using good engineering practice and generally accepted terrain-sensitive propagation models (with location and time variables of 10% and standard 3 arc-second digitized terrain data). The Agencies shall provide all data and calculations for determining compliance with this Arrangement upon request.
    • (2) In the event that the measured pfd at or beyond the border exceeds the value described in section 7.1(a), it is the responsibility of the licensee to bring the station’s pfd into compliance with section 7.1(a).
  • (b) Stations authorized under this provision shall be considered as secondary and shall neither be granted protection against harmful interference from stations that have primary use of their authorized frequency, nor shall they cause harmful interference to stations having primary use of their authorized frequency, regardless of whether they meet the pfd values specified in 7.1(a) above.
  • (c) Mobile stations exceeding 5 watts transmitter power output (TPO) shall not be operated in frequencies allotted for primary use of the other Agency within 30 km of the common border.
  • (d) Beyond 30 km of the common border, mobile stations operating in frequencies allotted for primary use of the other Agency must not exceed the pfd value specified in 7.1(a).
  • (e) The documentation issued by each Agency authorizing such stations to use these frequencies shall include a clause stating that such authorization is subject to the following conditions:
    • (1) In the event that the measured signal at or beyond the border is found to exceed -124 dB(W/m2)/25 kHz, the signal level shall be reduced accordingly;
    • (2) In the event that harmful interference occurs to any station that has primary use of the authorized frequency, regardless of signal strength, the licensee shall take immediate action to eliminate such interference. The Agency granting the authorization for secondary use is responsible for ensuring that remedial action is taken, up to and including revocation of the authorization.

7.2 Stations that were operating prior to August 1, 2011 and that comply with the pfd limits as described in Annex E shall be permitted to continue operations under their current parameters. Stations authorized under this provision shall neither be granted protection against harmful interference from stations that have primary use of their authorized frequency, nor shall they cause harmful interference to stations having primary use of their authorized frequency.

7.3 Canadian assignments within the coordination zone, listed in Tables C4-1 and C4-2 of Annex C, are operating according to a Special Coordination Procedure (SCP) signed between the Agencies in October 2001. Although this SCP is no longer in effect, the Canadian assignments listed in Tables C4-1 and C4-2 of Annex C may continue to operate in excess of the pfd limit listed in section 7.1(a) above until March 31, 2014 under the following conditions.

  • (a) Canadian assignments listed in Table C4-2 of Annex C shall be required to comply with the pfd limit listed in section 7.1(a) within 60 business days Footnote 2 upon notification by the FCC to Industry Canada that the 22 dBµV/m interference contour of a Canadian assignment overlaps with the 40 dBµV/m protected contour of a co-channel assignment in the United States, which assignment has been made part of the United States’ reconfiguration of the 800 MHz band.
  • (b) Canadian assignments listed in Tables C4-1 of Annex C shall be required to comply with the pfd limit listed in section 7.1(a) within 90 business daysFootnote 3 upon notification by the FCC to Industry Canada that the 22 dBµV/m interference contour of a Canadian assignment overlaps with the 40 dBµV/m protected contour of a co-channel assignment in the United States, which assignment has been made as part of the United States’ reconfiguration of the 800 MHz band. The FCC, however, shall exert good faith efforts to avoid assigning a frequency, in connection with 800 MHz band reconfiguration, that requires a Canadian assignment listed in Table C4-1 to comply with the pfd limit listed in section 7.1(a) prior to March 31, 2014.
  • (c) In exceptional circumstances in which the FCC may assign a channel unrelated to the 800 MHz band reconfiguration, which assignment creates the co-channel contour overlap described in section (a) and (b) above, the Agencies shall mutually agree to a time period, reasonable under the circumstances, for the Canadian assignment to comply with the pfd limit listed in section 7.1(a).
  • (d) Contour distances referred to in sections (a) and (b) above shall be derived from R-6602 curves, F(50,50) for the protected contour and F(50,10) for the interference contour.
  • (e) If a modification is made to a Canadian assignment, that assignment shall be subject to the provisions of section 7.1(a) and shall be removed from Annex C unless the modification causes no extension of the existing 22 dBµV/m interference contour further in the direction of the common border.
  • (f) After March 31, 2014, the Canadian assignments listed in Tables C4-1 and C4-2 of Annex C must comply with the pfd limit specified in section 7.1(a). After this date, the United States shall no longer be subject to the restrictions detailed in section (a), (b) or (c) above. The Agencies may agree to a longer period of time for individual Canadian assignments to exceed the pfd limit specified in section 7.1(a) but in this case the individual Canadian assignments shall neither be granted protection against harmful interference from stations that have primary use of their authorized frequency, nor shall they cause harmful interference to stations having primary use of their authorized frequency.

8. Information Exchange

8.1 To facilitate the coordination requirements of this Arrangement, the Agencies shall exchange information including, but not limited to: (1) licensee name(s); (2) licensed service areas; and (3) licensee point(s) of contact; or means to obtain the above information.

8.2 When necessary, the Agencies shall provide information to their respective licensees to facilitate the coordination requirements of this Arrangement.

8.3 To facilitate cross-border coordination between licensees, the Agencies shall encourage licensees to exchange data as listed in Annex D to this Arrangement.
