Sec.  90.531   Band plan.

   This section sets forth the band plan for the 764–776 MHz and 794–806 MHz
   public safety bands.

   (a) Base and mobile use. The 764–776 MHz band may be used for base, mobile
   or fixed (repeater) transmissions. The 794–806 MHz band may be used only for
   mobile or fixed (control) transmissions.

   (b) Narrowband segments. There are four band segments that are designated
   for use with narrowband emissions. Each of these narrowband segments is
   divided into 480 channels having a channel size of 6.25 kHz as follows:


------------------------------------------------------------------------
              Frequency range                        Channel Nos.

------------------------------------------------------------------------
              Frequency range                        Channel Nos.
------------------------------------------------------------------------
767-773 MHz................................  1-120
797-803 MHz................................  121-240.
------------------------------------------------------------------------

   (1) Wideband Interoperability channels. The following wideband channels are
   designated for nationwide Interoperability licensing and use, but are not
   available for licensing or use pending Commission adoption of a wideband
   Interoperability standard: 28–30, 37–39, 46–48, 73–75, 82–84, 91–93,
   148–150, 157–159, 166–168, 193–195, 202–204, 211–213.

   (2) Wideband reserve channels. The following wideband channels are reserved:
   1–27, 94–120, 121–147, 214–240.

   (3) Wideband general use channels. All wideband channels established in
   paragraph (c), except for those listed in paragraphs (c)(1) and (c)(2) of
   this section, are designated for assignment to public safety eligibles
   subject to Commission-approved regional planning committee regional plans.

   (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  Sec. 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) Wideband. Two or three contiguous wideband (50 kHz) channels may be used
   in combination as 100 kHz or 150 kHz channels, respectively. The lower (in
   frequency) channel for two channel combinations must be a channel whose
   number is equal to 1+(3xn) or 2+(3xn), where n = any integer between 0 and
   79, inclusive (e.g., channel number 1, 2, 4, 5, 7, 8,  *  *  * 238, 239).
   The lowest (in frequency) channel for three channel combinations must be a
   channel whose number is equal to 1+(3xn), where n = any integer between 0
   and 79, inclusive (e.g., channel number 1, 4, 7, 10,  *  *  * 238). 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 “1–3”
   for a three channel combination.

   (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.
