  §  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.

   Table A1--U.S. and Mexico Primary Channels in Sharing Zone
   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.

   Table A2--Limits on Effective Radiated Power (ERP) and Antenna Height
   Average of the antenna height above average terrain on standard radials
   in the direction of the common border
   (meters)^1 Maximum ERP in any direction toward the common border per 25
   kHz
   (watts)
   0 to 503 500
   Above 503 to 609 350
   Above 609 to 762 200
   Above 762 to 914 140
   Above 914 to 1066 100
   Above 1066 to 1219 75
   Above 1219 to 1371 70
   Above 1371 to 1523 65
   Above 1523 5

   ^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 to this paragraph (a)(5).

   California: San Luis Obispo, Kern, San Bernardino, Santa Barbara,
   Ventura, Los Angeles, Orange and Riverside.

   (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) Except as specified in § 90.616, the channels listed in Table 1 of
   this section are available to applicants eligible in the
   Industrial/Business Pool of subpart C of this part but exclude
   Specialized Mobile Radio Systems as defined in § 90.603(c). These

   Channels numbered above 200 may only be used subject to the power flux
   density limits at or beyond the Mexico border as stated in paragraph
   (4) of this section.

   (3) The specific channels that are available for licensing in the band
   896-901/935-940 MHz within the Mexico border region are subject to
   Effective Radiated Power (ERP) and Antenna Height limitations as
   indicated in Table 3 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").

   8 127° W-143° W (100-140 km from border) 1-830.

   (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.

   (4) Stations may be authorized on Canada Primary channels in the Canada
   Border Regions provided the maximum power flux density (PFD) per 25 kHz
   at or beyond the border does not exceed -107 dB(W/m2). Stations
   authorized on Canada Primary channels will be secondary to stations in
   Canada unless otherwise specified in an international agreement between
   the U.S. and Canada.

   (5) Stations authorized to operate within 30 kilometers of the center
   city coordinates listed in Table C5 may operate according to the band

   section are available in the Canada Border Regions for non-cellular
   operations to eligible applicants in the Public Safety Category which
   consists of licensees eligible in the Public Safety Pool of subpart B

   (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

   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) 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: 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.

   Table 28--Additional Channels Available

   [Regions 1-6]
   Region Channel No.'s Effective radiated power
   1            201-397 See Table 29
   2            121-399 See Table 29
   3            341-399 See Table 29
   4            201-397 See Table 29
   5            201-397 See Table 30
   6            201-397 See Table 29

   Authorizations for stations using these channels will be 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 the values specified in
   tables 29 or 30 at or beyond the U.S./Canada border.
