[Code of Federal Regulations] [Title 47, Volume 5] [Revised as of October 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 47CFR101.109] [Page 686-687] TITLE 47--TELECOMMUNICATION COMMISSION (CONTINUED) PART 101_FIXED MICROWAVE SERVICES--Table of Contents Subpart C_Technical Standards 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 [[Page 687]] 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. ------------------------------------------------------------------------ Frequency band (MHz) Maximum authorized bandwidth ------------------------------------------------------------------------ 928 to 929................................ 25 kHz 1 5 6 932 to 932.5, 941 to 941.5................ 12.5 kHz 1 5 6 932.5 to 935, 941.5 to 944................ 200 kHz \1\ 952 to 960................................ 200 KHz 1 5 6 1,850 to 1,990............................ 10 MHz \1\ 2,110 to 2,130............................ 3.5 MHz 2,130 to 2,150............................ 800 or 1600 KHz \1\ 2,150 to 2,160............................ 10 MHz 2,160 to 2,180............................ 3.5 MHz 2,180 to 2,200............................ 800 or 1600 KHz \1\ 2,450 to 2,483.5.......................... 625 KHz \2\ 2,483.5 to 2,500.......................... 800 KHz 3,700 to 4,200............................ 20 MHz 5,925 to 6,425............................ 30 MHz \1\ 6,425 to 6,525............................ 25 MHz 6,525 to 6,875............................ 10 MHz \1\ 10,550 to 10,680.......................... 5 MHz \1\ 10,700 to 11,700.......................... 40 MHz \1\ 12,200 to 12,700\8\....................... 500 megahertz 13,200 to 13,250.......................... 25 MHz 17,700 to 18,140.......................... 220 MHz \1\ 18,140 to 18,142.......................... 2 MHz 18,142 to 18,580.......................... 6 MHz 18,580 to 18,820.......................... 20 MHz \1\ 18,820 to 18,920.......................... 10 MHz 18,920 to 19,160.......................... 20 MHz \1\ 19,160 to 19,260.......................... 10 MHz 19,260 to 19,700.......................... 220 MHz \1\ 21,200 to 23,600.......................... 50 MHz \1\ \4\ 24,250 to 25,250.......................... 40 MHz \7\ 27,500 to 28,350.......................... 850 MHz 29,100 to 29,250.......................... 150 MHz 31,000 to 31,075.......................... 75 MHz 31,075 to 31,225.......................... 150 MHz 31,225 to 31,300.......................... 75 MHz 38,600 to 40,000.......................... 50 MHz \7\ Above 40,000.............................. (\3\) ------------------------------------------------------------------------ \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. \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.
