\1\ Offset Group 201 is available for conventional system use only.
Offset Channel 201 is not available for use in the U.S./Mexico border
area.
(2) Certain channels in the 821-824/866-869 MHz band are also
available to eligible applicants in the Public Safety Category in areas
within 110 kilometers (68.4 miles) of the U.S./Mexico border. These
channels will be assigned according to the policies defined in the
Report and Order of Gen. Docket No. 87-112 (See Sec. 90.16). The
following channels are available only for mutual aid purposes as defined
in Gen. Docket No. 87-112: channels 601, 639, 677, 715, and 753. Certain
channels in the 896-901/935-940 MHz band are also available in areas
within 110 kilometers (68.4 miles) of the U.S./Mexico border. The
specific channels that are available for licensing in the bands 821-824/
866-869 and 896-901/935-940 MHz within 110 kilometers (68.4 miles) of
the Mexico border are listed in tables 1B, 2B, 3B, and 4B and are
subject to Effective Radiated Power (ERP) and Antenna Height limitations
as indicated in table 1C. In addition, all channels designated for use
within Mexico in the 821-824/866-869 MHz and 896-901/935-940 MHz bands
are available for assignment to U.S. stations within 110 kilometers
(68.4 miles) of the Mexico border 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).

(b) U.S./Canada border area. The following criteria shall govern the
assignment of frequency pairs (channels) in the 806-821/851-866 and 896-
901/935-940 MHz bands for stations located in the U.S./Canada border
area. These channels are available for assignment for conventional or
trunked systems in accordance with all applicable sections of this
subpart. They are available for intercategory sharing as indicated in
Sec. 90.621(g). Specific provisions for use of the 821-824/866-869 MHz
bands in the U.S./Canada border area are contained in paragraph (c) of
this section, and provisions for use of the 896-901/935-940 MHz bands in
the U.S./Canada border are contained in paragraph (d) of this section.
(1) The U.S./Canada border area is divided into eight geographical
regions with U.S. channel allocations shown in table 5.
Table 5--Geographical Regions

(2) Station authorizations in Regions 1-4 and Regions 6-8 will be
subject to Effective Radiated Power (ERP) and Effective Antenna Height
(EAH) limitations as indicated in table 6. Stations in Region 5 will be
subject to the ERP and antenna height above mean sea level limitations
in table 8. Effective Radiated Power (ERP) is defined as the product of
the power supplied to the antenna and its gain relative to a half-wave
dipole in a given direction. Effective Antenna Height is calculated by
subtracting the Assumed Average Terrain Elevation (AATE) given in table
7 from the antenna height above mean sea level.

------------------------------------------------------------------------
(4) Coordination with Canada will be required:
(i) For frequencies in the 808.2625-809.7375/853.2625-854.7375 MHz
and 817.2625-818.7375/862.2625-863.7375 MHz bands, for stations to be
located in the geographical area in Region 1 enclosed by the United
States border, the meridian 71 deg. W and the line beginning at the
intersection of 44 deg.25'N, 71 deg. W, then running by great circle arc
to the intersection of 45 deg. N, 70 deg. W, then North along meridian
70 deg. W to the intersection of 45 deg.45'N, then running West along
45 deg.45'N to the intersection of the United States--Canada border.
[[Page 546]]
(ii) For frequencies in the 808.2625-811.2375/853.2625-856.2375 MHz
and 815.7625-818.7375/860.7625-863.7375 MHz bands, for stations to be
located in the geographical area in Region 3 enclosed by the meridian
81 deg. W longitude, the arc of a circle of 100 km radius centered at
the intersection of 81 deg. W longitude and the northern shore of Lake
Erie and drawn clockwise from the southerly intersection with 81 deg. W
longitude to intersect the United States-Canada border, and the United
States-Canada border.
(5) Applicants requesting authorizations in the frequency bands in
the geographical areas listed below shall submit documentation
indicating compliance with the following protection criteria to the
indicated Canadian television station. Protection to Canadian television
assignments and allotments is based on the field strength of an
interfering mobile radio signal at the TV station's calculated Grade B
contour (64 dBu) not exceeding the TV field strength by more than 20 dB
(i.e., 84 dBu). The field strength of the TV assignment or allotment is
calculated using the R6602 [F(50,50)] propagation curves and any land
mobile base station interfering signal is calculated using the R6602
[F(50,10)] propagation curves at a receiving effective antenna height of
9.1 meters (30 feet). Where the calculated field strength of the TV
assignment or allotment exceeds the Grade B contour value of 64 dBu at
the Canada/U.S.A. border, the land mobile radio signal may not exceed
the actual calculated TV field strength at the border by more than 20
dB.

by Channel No. 2 at 806.0375 MHz and proceed with uniform 25 kHz spacing
to the band end, with Channel No. 600 at 820.9875 MHz. Corresponding
base station frequencies, separated by 45 MHz from the mobile control
frequencies, will commence with Channel No. 1 at 851.0125 MHz and end
with Channel No. 600 at 865.9875 MHz.
(ii) Channels will be arranged into 5-channel groups. Because of the
distribution and differing number of channels available for United
