The spreading loss must be calculated using the free space formula taking into account any antenna discrimination in the direction of the border. Authorizations for stations using channels allotted to Mexico on a primary basis will be secondary to Mexican operations and conditioned to require that licensees take immediate action to eliminate any harmful interference resulting from the station's transmitted signal exceeding −107 dB (W/m2).
(c) Use of 800 MHz Band in Canada Border Region. All operations in the 806-824/851-869 MHz band within 140 km (87 miles) of the U.S./Canada border (“U.S./Canada border area”) shall be in accordance with international agreements between the U.S. and Canada.
(1) The U.S./Canada border area is divided into the following geographical regions (“Canada Border Regions”). U.S. primary channels are shown in the table by region. The remaining channels are primary to Canada (“Canada Primary channels”).

(3) In Region 5, Channels except as specified in § 90.616, channels 201-397 may be authorized in the United States under the following conditions:
(i) An assignment may be made if the predicted power flux density (PFD) of a proposed station's signal does not exceed −107 dBW/m2 at the border. The prediction of the PFD is calculated based upon a modified Longley-Rice point-to-point propagation model with time and location variabilities of 10 percent[3] and 3-second digitized terrain date[4] .
(ii) Authorizations for Channels 201-397 in Region 5 are secondary to Canadian operations and conditioned to require that licensees take immediate action to eliminate any harmful interference resulting from the station's transmitted signal exceeding −107 dBW/m2 at or beyond the U.S./Canada border.
(4) Channel Except as specified in § 90.616, channel assignments for stations to be located in the geographical area in Region 1 enclosed by the United States-Canada border, the meridian 71° W and the line beginning at the intersection of 44°25′ N, 71° W, then running by great circle arc to the intersection of 45° N, 70° W, then North along meridian 70° W to the intersection of 45°45′ N, then running West along 45°45′ N to the intersection of the United States-Canada border, will be only for channels 121 through 160, inclusive, and will be limited to assignments with 11 kHz or less necessary bandwidth. Coordination with Canada will be required for these channels.
(5) Channel Except as specified in § 90.616, channel assignments for stations to be located in the geographical area in Region 3 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 80°30′ W longitude to intersect the United States-Canada border West of 81° W, and the United States-Canada border, will be only for channels 121 through 230, inclusive, and will be limited to assignments with 11 kHz or less necessary bandwidth. Coordination with Canada will be required for these channels. U.S. stations must protect Canadian stations operating on channels 121 through 230 within an area of 30 km radius from the center city coordinates (referenced to North American Datum 1983 (NAD83)) of London, Ontario (42°59′00.1″ N, 81°13′59.5″ W).
(6) Additional channels available - The : Except as specified in § 90.616, the channels listed in table 28 are available for assignment in Regions 1-6 if the maximum power flux density (PFD) of the station's transmitted signal does not exceed the limits specified in tables 29 and 30 in this section. The spreading loss shall be calculated using the free space formula taking into account any antenna discrimination in the direction of the border.
