§ 90.531 Band plan.
This section sets forth the band plan for the 763-775 MHz and 793-805
MHz public safety bands.
(a) Base and mobile use. The 763-775 MHz band may be used for base,
mobile or fixed (repeater) transmissions. The 793-805 MHz band may be
used only for mobile or fixed (control) transmissions.
(b) Narrowband segments. There are two band segments that are
designated for use with narrowband emissions. Each of these narrowband
segments is divided into 960 channels having a channel size of 6.25 kHz
as follows:
Frequency range Channel Nos.
769-775 MHz 1-960

(6) Narrowband general use channels. All narrowband channels
established in paragraph (b) of this section, other than those listed
in paragraphs (b)(1), (b)(2), (b)(4) and (b)(5) of this section are
designated to public safety eligibles subject to Commission approved
regional planning committee regional plans. Voice operations on these
channels are subject to compliance with the spectrum usage efficiency
requirements set forth in § 90.535(d).
(7) Secondary trunking channels. The following channel pairs are
reserved for secondary trunking operations: 21/981, 22/982, 101/1061,
102/1062, 181/1141, 182/1142, 261/1221, 262/1222, 659/1619, 660/1620,

may be used only in combination with the appropriate adjacent
Interoperability channel pairs specified in paragraph (b)(1)(iii) of
this section in trunked systems.
(c) [Reserved]
(d) Combining channels. Except as noted in this section, at the
discretion of the appropriate regional planning committee, contiguous
channels may be used in combination in order to accommodate
requirements for larger bandwidth emissions, in accordance with this
paragraph. Interoperability channels may not be combined with channels
in another group except for channels for secondary trunking channels.
(1) Narrowband. Subject to compliance with the spectrum usage
efficiency requirements set forth in § 90.535, two or four contiguous
narrowband (6.25 kHz) channels may be used in combination as 12.5 kHz
or 25 kHz channels, respectively. The lower (in frequency) channel for
two channel combinations must be an odd ( i.e., 1, 3, 5 * * *)
numbered channel. The lowest (in frequency) channel for four channel
combinations must be a channel whose number is equal to 1+(4xn), where
n = any integer between 0 and 479, inclusive ( e.g., channel number 1,
5, * * * 1917). Channel combinations are designated by the lowest
and highest channel numbers separated by a hyphen, e.g., "1-2" for a
two channel combination and "1-4" for a four channel combination.
(2) [Reserved]
(e) Channel pairing. In general, channels must be planned and assigned
in base/mobile pairs that are separated by 30 MHz. However, until
December 31, 2006, channels other than those listed in paragraphs
(b)(1) and (c)(1), may be planned and assigned in base/mobile pairs
having a different separation, where necessary because 30 MHz
base/mobile pairing is precluded by the presence of one or more
co-channel or adjacent channel TV/DTV broadcast stations.
(f) Internal guard band. The internal guard band (768-769/798-799 MHz)
is reserved.
(g) Broadband. The 763-768 MHz and 793-798 MHz bands are allocated for
broadband communications pursuant to the Public Safety Broadband
License.
