Dear Mr. Binder:

The Federal Communications Commission (FCC) and National Telecommunications and Information Administration (NTIA) of the United States of America have jointly developed an arrangement to formalize coordination with Industry Canada (IC) of frequency assignments in the 17.7 to 19.7 and 21.2 to 23.6 GHz bands. An informal arrangement, based on discussions between representative from both countries in Radio Technical Liaison Committee (RTLC) meetings, has been utilized for nearly six years.

On behalf of Scott Blake Harris, Chief, International Bureau, Federal Communications Commission and Richard D. Parlow, Associate Administrator, National Telecommunications and Information Administration, United States Department of Commerce, I am forwarding for your consideration an arrangement which we believe will satisfy both countries' spectrum needs in the 17.7 to 19.7 and 21.2 to 23.6 GHz bands. This arrangement would be applied provisionally until the definitive entry into force of a replacement for the Agreement Concerning the Coordination and Use of Radio Frequencies Above Thirty Megacycles per Second, with Annex (Above 30 MHz Agreement), as amended.1

If the enclosed arrangement is acceptable to your agency, we propose that it constitute a formal arrangement modifying the "Technical Annex" of Above 30 MHz Agreement. The Arrangement will become effective upon receipt of your signed copy of the enclosed Arrangement.

Sincerely,

Aileen A. Pisciotta

Arrangement between the Federal Communications Commission and the National Telecommunications and Information Administration of the United States of America and Industry Canada Concerning the Coordination of Fixed and Mobile Stations Operating in Specific Band Segments between 17.7 GHz and 23.6 GHz along the United States-Canada Border

1. This Arrangement between the Federal Communications Commission of the United States of America (FCC), the National Telecommunications and Information Administration (NTIA) on the one hand, and Industry Canada (IC)2 on the other hand, herein referred to as the Agencies, covers the coordination of fixed and mobile stations to be operated in specific band segments between 17.7 GHz and 23.6 GHz along the United States-Canada border.

1.1 The coordinating agency for the United States of America is the Federal Communications Commission while the coordinating agency for Canada is Industry Canada.

1.2 The relevant USA Agency and the Canadian Agency will coordinate with the other prior to licensing all stations in the fixed3 and mobile services of its respective country which are to be operated in the bands segments 17.7 to 19.7 and 21.2 to 23.6 GHz within 55 km of the United States-Canada border.

1.3 This Arrangement is subject to review at any time at the request of either of the relevant USA Agency or the Canadian Agency.

1.4 Special coordination arrangements may be initiated under this Arrangement by either Agency and implemented subject to the approval of both Agencies.

1.5 This Arrangement will be applied provisionally until the definitive entering into force of a replacement for the Agreement Concerning the Coordination and Use of Radio Frequencies Above Thirty Megacycles per Second, with Annex4, as amended5 (Above 30 MHz Agreement).

1.6 With respect to the coordination of stations in the fixed and mobile services in the bands 17.7 to 19.7 and 21.2 to 23.6 GHz along the United States-Canada border and licensed by either FCC, NTIA or IC, this Arrangement supersedes the provisions of:

  1. Item 71 of the "Technical Annex" to the Above 30 MHz Agreement which states that coordination is not required at this time for operations in the band 17.7-23.0 GHz;
  2. Item 72 of the "Technical Annex" to the Above 30 MHz Agreement which states that coordination for operations in the band 23.0-24.25 GHz are to be in accordance with "Arrangement C" (fixed RADARs) to the Above 30 MHz Agreement.

U.S.-Canada Coordination Agreement in the band 17.7-17.8 GHz

It is agreed that the U.S. Coordination Agreement for Frequencies Above 30 MHz will be modified as soon as possible to include protection of fixed service and broadcasting-satellite receivers operating on either side of the border. This agreement is based upon the recognition that both the fixed service and the broadcasting-satellite service are primary in the 17.7-17.8 GHz band. The following provisions, to which both the U.S. and Canada agree, are designed to ensure the reasonable protection and operation of these services within each country:

  1. The power flux density limit already established in Article 28 for this band will be applied to the BSS for the protection of the fixed service;
  2. There will be a new ITU footnote ensuring protection of the BSS from FSS (Space-to-Earth) operations;
  3. The BSS will not, except by mutual agreement, be implemented before 1 January 2007;
  4. Neither country will authorize new fixed systems in this band, except under the conditions specified in 5 below; and,
  5. Fixed systems operating in the band 17.7-17.8 GHz in either country will be required to make whatever adjustments are necessary so as to limit the aggregated power flux density of such systems into the neighboring country to -109 dB (W/m2 ) over any 1 MHz in this frequency band in any area where the BSS is in use. This value may be modified by mutual agreement.
