Sec.  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.

\1\ The maximum bandwidth that will be authorized for each particular
  frequency in this band is detailed in the appropriate frequency table
  in  Sec.  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.
\2\ 1250 KHz, 1875 KHz, or 2500 KHz on a case-by-case basis.
\3\ To 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.
\4\ For exceptions, see  Sec.  101.147(s).
\5\ A 12.5 kHz bandwidth applies only to frequencies listed in  Sec. 
  101.147(b)(1) through (4).
\6\ For frequencies listed in  Sec.  101.147(b)(1) through (4),
  consideration will be given on a case-by-case basis to authorizing
  bandwidths up to 50 kHz.
\7\ For 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  Sec.  101.111(a)(1) or in
   Sec.  101.111(a)(2)(ii) and (iii) as appropriate.
\8\ For incumbent private operational fixed point-to-point stations in
  this band (those not licensed as MVDDS), the maximum bandwidth shall
  be 20 MHz.
