§ 90.531 Band plan.
This section sets forth the band plan for the 758-775 MHz and 788-805 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

(b)(2) are designated for priority access by public safety incumbents
relocating from the 470-512 MHz band in the urban areas specified in
§ § 90.303 and 90.305 of the Commission's rules provided that such incumbent
commits to return to the Commission an equal amount of T-Band spectrum and
obtains concurrence from the relevant regional planning committee(s). Public
safety T-Band incumbents shall enjoy priority access for a five year period

temporary deployable mobile trunked infrastructure (F2BT) that could be
transported into an incident area to assist with emergency response and
recovery.
(iii) General Use. Outside the urban areas specified in § § 90.303 and 90.305

these channels are subject to compliance with the spectrum usage efficiency
requirements set forth in § 90.535(d).
(6) Narrowband general use channels. All narrowband channels established in
this paragraph (b), other than those listed in paragraphs (b)(1), (b)(4),
(b)(5), and (b)(7) of this section are reserved 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) Air-ground channels. The following channels are reserved for air-ground
communications to be used by low-altitude aircraft and ground based

(i) Airborne use of these channels is limited to aircraft flying at or below
457 meters (1500 feet) above ground level.
(ii) Aircraft are limited to 2 watts effective radiated power (ERP) when
transmitting while airborne on these channels.
(iii) Aircraft may transmit on either the mobile or base transmit side of
the channel pair.
(iv) States are responsible for the administration of these channels.
(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 758-768 MHz and 788-798 MHz bands are allocated for
broadband communications.
