§ 90.619 Operations within the U.S./Mexico and U.S./Canada border areas.
(a) Use of frequencies in 800 MHz band in Mexico border region. All
operations in the 806-824/851-869 MHz band within 110 km (68.4 miles)
of the U.S./Mexico border (“Mexico border region”) shall be in
accordance with international agreements between the U.S. and Mexico.
Channels 231-710 are offset 12.5 kHz lower in frequency than those
specified in the table in § 90.613. Stations located on Mt. Lemmon,
serving the Tucson, AZ area, will only be authorized offset
frequencies.
(b) Use of frequencies in 900 MHz Band in Mexico border region. All
operations in the 896-901/935-940 MHz band within the Mexico border
region shall be in accordance with international agreements between the
U.S. and Mexico.
(1) The channels listed in Table 1 below are available to applicants
eligible in the Industrial/Business Pool of subpart C of this part but
exclude Special Mobilized Radio Systems as defined in § 90.603(c).
These frequencies are available within the Mexico border region.
Specialized Mobile Radio (SMR) systems will not be authorized on these
frequencies.
For multi-channel systems, channels may be grouped vertically or
horizontally as they appear in the following table. Channels numbered
above 200 may be used only subject to the power flux density limits
stated in paragraph (a)(2) of this section:

(4) All channels in the 896-901/935-940 MHz band are available for
assignment to U.S. stations within the Mexico border region if the
maximum power flux density (pfd) of the station's transmitted signal at
any point at or beyond the border does not exceed −107 dB (W/m2 ). 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”).

(2) Stations authorized on U.S. primary channels in all Canada Border
Regions, except Region 5, will be subject to the Effective Radiated
Power (ERP) and Effective Antenna Height (EAH) limitations listed in
Table C2. The Effective Antenna Height is calculated by subtracting the
Assumed Average Terrain Elevation (AATE) listed in Table C3 from the
antenna height above mean sea level.

The following criteria shall govern the assignment of frequency pairs
(channels) in the 896-901/935-940 MHz band for stations located in the
U.S./Canada border area. They are available for assignments for
conventional or trunked systems in accordance with applicable sections
of this subpart.

Channel Designations, are available to eligible applicants for use in
the U.S./Canada border area as shown in table 27. Additionally,
Channels 71, 75, 79, 151, 155, and 159 are available in all regions
only for implementation of an Advanced Train Control System as defined
in 3 FCC Rcd 427 (1988) (Advanced Train Control Waiver).

Note: For assignments in the 896-901/935-940 MHz bands, the cities of
Akron, Ohio (41°05′00″ N, 81°30′40″ W) and Youngstown, Ohio (41°05′57″
N, 80°39′02″ W) are considered outside of Region 3, and Syracuse, New
York (43°03′04″ N, 76°09′14″ W) is considered outside of Region 2.
These cities are defined as an area with the given center coordinates
and encompassing a circle of 30 km radius.
(2) All frequency assignments made pursuant to paragraph (d)(1) of this
section shall comply with the requirements of § 90.619(b).
(3) In Region 5, 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 date4 .
3 See note 1, paragraph (c) of this section.
4 See note 2, paragraph (c) of this section.
(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 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 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 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. The spreading loss shall be
calculated using the free space formula taking into account any antenna
discrimination in the direction of the border.
