  §  101.109   Bandwidth.

   (a) Each authorization issued pursuant to these rules will show, as the
   emission designator, a symbol representing the class of emission which
   must be prefixed by a number specifying the necessary bandwidth. This
   figure does not necessarily indicate the bandwidth actually occupied by
   the emission at any instant. In those cases where part 2 of this
   chapter does not provide a formula for the computation of the necessary
   bandwidth, the occupied bandwidth may be used in the emission
   designator.

   (b) Stations in this service will be authorized any type of emission,
   method of modulation, and transmission characteristic, consistent with
   efficient use of the spectrum and good engineering practice, except
   that Type B, damped-wave emission will not be authorized.

   (c) The maximum bandwidth which will be authorized per frequency
   assigned is set out in the table that follows. Regardless of the
   maximum authorized bandwidth specified for each frequency band, the
   Commission reserves the right to issue a license for less than the
   maximum bandwidth if it appears that a lesser bandwidth would be
   sufficient to support an applicant's intended communications.

   ^1The maximum bandwidth that will be authorized for each particular
   frequency in this band is detailed in the appropriate frequency table
   in § 101.147. If contiguous channels are aggregated in the
   928–928.85/952–952.85/956.25–956.45 MHz, the 928.85–929/959.85–960 MHz,
   or the 932–932.5/941–941.5 MHz bands, then the bandwidth may exceed
   that which is listed in the table.

   ^21250 KHz, 1875 KHz, or 2500 KHz on a case-by-case basis.

   ^3To be specified in authorization. For the band 92 to 95 GHz, maximum
   bandwidth is licensed in one segment of 2 GHz from 92–94 GHz and one
   0.9 GHz segment from 94.1 to 95 GHz, or the total of the loaded band if
   smaller than the assigned bandwidth.

   ^4For exceptions, see § 101.147(s).

   ^5A 12.5 kHz bandwidth applies only to frequencies listed in
   § 101.147(b)(1) through (4).

   ^6For frequencies listed in § 101.147(b)(1) through (4), consideration
   will be given on a case-by-case basis to authorizing bandwidths up to
   50 kHz.

   ^7For channel block assignments in the 24,250–25,250 MHz and
   38,600–40,000 MHz bands, the authorized bandwidth is equivalent to an
   unpaired channel block assignment or to either half of a symmetrical
   paired channel block assignment. When adjacent channels are aggregated,
   equipment is permitted to operate over the full channel block
   aggregation without restriction.

   Note to Footnote 7: Unwanted emissions shall be suppressed at the
   aggregate channel block edges based on the same roll-off rate as is
   specified for a single channel block in § 101.111(a)(1) or in
   § 101.111(a)(2)(ii) and (iii) as appropriate.

   ^8For incumbent private operational fixed point-to-point stations in
   this band (those not licensed as MVDDS), the maximum bandwidth shall be
   20 MHz.
