  2. Within the area of a 30-km radius from the city centre coordinates of London, Ontario 42° 59'N, 81° 14'W, Canada shall have unrestricted geographic use of Sector 2 frequencies on an uncoordinated basis.
Editor’s Note: 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 as well as the areas defined in (a) and (b) of annex B, section 2.

3. Coordination necessitated by the special sharing arrangements

As a result of the division of spectrum described above, portions of the bands allotted to both countries overlap. Therefore, proposed frequency assignments in the overlapping portions in those bands, as described in paragraphs (a) and (b) below, will be coordinated.

Coordination is required for assignments on the frequencies listed below in the following geographical areas (see annex C, figure C1):

  1. the geographical area in Canada enclosed by the Canada-United States border, the meridian 71° W; and the line beginning at the intersection of 72° W and the Canada-United States 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
  2. the geographical area in the United States enclosed by the Canada-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 Canada-United States border.

4. Special provisions concerning the use of the bands 768-776 MHz and 798-806 MHz

4.1 Use of frequencies allotted to the United States

Frequencies allotted for primary, unrestricted use by the United States may be assigned for use within the coordination zone under the begin deletionfollowing.end deletion conditions established in section 7 of Arrangement Q – Sharing arrangement between the Department of Industry Canada and the Federal Communications Commission of the United States of America concerning the use of the frequency bands 768-776 MHz and 798-806 MHz by the Land Mobile Service along the Canada‑United States border, published in October 2013.

Editor’s note: Arrangement Q has been in effect since 2013 and covers the use of frequencies in this SRSP.
  1. in Sharing Zones I and III, the maximum power flux‑density (pfd) at or beyond the border does not exceed -121 dbW/m2/kHz
  2. in Sharing Zone II, the maximum pfd at or beyond the border does not exceed -124 dBW/m2/kHz;
  3. in making the determination (calculation) of pfd, good engineering practices and generally accepted terrain-sensitive propagation models with time and location variabilities of 10%, and at least standard, 3 arc-second digitized terrain data shall be used
  4. stations are considered as secondary and are not granted protection against harmful interference from stations that have primary use of their authorized frequency. They also must not cause harmful interference to stations having primary use of their authorized frequency regardless of whether they meet the pfd values specified in (a) and (b) above
  5. mobile stations exceeding 5 watt transmitter power output (TPO) are not authorized within 30 km of the border
  6. in the event that the actual signals at or beyond the border are found to exceed the values specified in (a) and (b) above, the signal level shall be reduced accordingly and
  7. if the actual signals are found to cause harmful interference to any stations that have primary use of their authorized frequency regardless of signal strength, the licensee shall take immediate action to eliminate such interference. The regional director granting the authorization for secondary use is responsible for ensuring that remedial action is taken, up to and including revocation of the authorization

    In the event that a Canadian and a U.S. licensee agree that the technical conditions stated in (a), (b) and (e) above, for proposed station(s) within the sharing zones must be exceeded in certain exceptional circumstances for more efficient operation of the land mobile services authorized in this annex, either Industry Canada or the Federal Communications Commission (FCC) may initiate special coordination concerning those proposed variation(s) in technical conditions with the other administration through an exchange of correspondence. Such variation(s) may be implemented only through approval of both Industry Canada and the FCC

In making assignments for use of any frequency in the bands 768-776 MHz and 798-806 MHz by the land mobile service, U.S. TV stations must be protected according to the following desired to undesired (D/U) signal ratios:

  1. the minimum D/U ratio is 40 db for co-channel analogue TV stations and 0 db for adjacent channel analogue TV stations. The minimum D/U ratio must be satisfied within the analogue TV stations’ 64 dbμV/m contour and is based on interference at 50% of locations, no more than 10% of the time
  2. the minimum D/U ratio is 17 db for co-channel DTV stations and -23 db for adjacent channel DTV stations. The minimum D/U ratio must be satisfied within the DTV stations’ 41 dBμV/m contour and is based on interference at 50% of locations, no more than 10% of the time
Editor’s Note On May 10, 2013, the Department and the Federal Communication Commission (FCC) signed Arrangement Q concerning the sharing/use of the frequency bands 768-776 MHz and 798-806 MHz by the land mobile service along the common border. Arrangement Q does not have provisions to protect U.S. TV stations.

5. Limits of effective radiated power (ERP) and antenna height along the Canada-United States border

ERP is defined as the product of the power supplied to the antenna and its gain relative to a half-wave dipole in a given direction.

For base stations in sharing zones I and III, sectors 1 and 2 and the protection zones, table B7 lists the limits of ERP corresponding to the effective antenna height (EAH) ranges shown. In this case, EAH is calculated by subtracting the assumed average terrain elevation given in table B9 from the antenna height above mean sea level.

Table B9 lists the values of assumed average terrain elevations (AATE) within the sharing and protection zones on both sides of the Canada-United States border.
