§ 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 (68.35 miles) of
the U.S./Mexico border (“Sharing Zone”) shall be in accordance with
international agreements between the U.S. and Mexico.
(1) The U.S. and Mexico divide primary access to channels in the Sharing
Zone as indicated in Table A1 below.

Channels Primary access
1-360 U.S.
361-610 Mexico.
611-830 U.S.-Mexico Co-Primary.
(2) Stations authorized on U.S. primary channels in the Sharing Zone are
subject to the effective radiated power (ERP) and antenna height limits
listed below in Table A2.

^1Standard radials are 0°, 45°, 90°, 135°, 180°, 225°, 270° and 315° to True
North. The height above average terrain on any standard radial is based upon
the average terrain elevation above mean sea level.
(3) Stations may be authorized on channels primary to Mexico in the Sharing
Zone provided the maximum power flux density (PFD) at any point at or beyond
the border does not exceed −107 db(W/m2) per 25 kHz of bandwidth. Licensees
may exceed this value only if all potentially affected counterpart operators
in the other country agree to a higher PFD level.
(4) Stations authorized on U.S.-Mexico co-primary channels in the Sharing
Zone are permitted to exceed a maximum power flux density (PFD) of −107
db(W/m2) per 25 kHz of bandwidth at any point at or beyond the border only
if all potentially affected counterpart operators of 800 MHz high density
cellular systems, as defined in § 90.7, agree.
(5) Channels in the Sharing Zone are available for licensing as indicated in
Table A3 below.

(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”).

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
percent3 and 3-second digitized terrain date4.
3See note 1, paragraph (c) of this section.
4See 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.
