(c) Explanation of assignment limitations appearing in the frequency table of paragraph (b) of this section:

(1) This frequency is available for assignment only to base or mobile stations operating wholly within Standard Metropolitan Areas having 50,000 or more population (1950 Census).

(2) This frequency is also available to Business Radio Service licensees for use at stations outside Standard Metropolitan Areas having 50,000 or more population (1950 Census).

(3) The requirements for secondary fixed use of frequencies in this band are set forth in § 90.261.

(4) Subpart L contains rules for assignment of frequencies in the 470-512 MHz band.

(5) Subpart S contains rules for assignment of frequencies in the 806-821/851-866 and 896-901/935-940 MHz bands.

(6) Assignment of frequencies above 928 MHz for operational-fixed stations is governed by part 94 of this chapter.

(7) This frequency band is available to stations in this service subject to the provisions of § 90.259.

(8) Available only on a shared basis with stations in other services, and subject to no protection from interference due to the operation of industrial, scientific, or medical (ISM) devices. In the 2483.5-2500 MHz band, no applications for new or modification to existing stations to increase the number of transmitters will be accepted. Existing licensees as of July 25, 1985, or on a subsequent date following as a result of submitting an application for license on or before July 25, 1985, are grandfathered and their operation is co-primary with the Radiodetermination Satellite Service.

(9) Use of this frequency band is limited to developmental operation and is subject to the provisions of subpart Q.

(10) This frequency is shared by stations in the Forest Products Radio Service in the States of Washington, Oregon, Idaho, and Montana in areas at least 64 km (40 miles) removed from the center of urbanized areas of 200,000 or more population, 1970 Decennial Census. (Provided that, taxicab operations within the specified urbanized areas will not be authorized on frequencies shared with the Forest Products Radio Service until the unshared frequencies are fully utilized.) For two-frequency systems, separation between base and mobile transmit frequencies is 5 MHz; however, a mobile station may be assigned the frequency of an associated base station. (Such operation may, however, subject the single-frequency system to interference that would not occur to a two-frequency system.)

(11) This frequency is shared with the Forest Products and Special Industrial Radio Services. Use of this frequency is limited to stations located at least 80.5 km. (50 miles) from the center of any urbanized area of 600,000 or more population (U.S. Census of Population, 1970).

(12) Frequencies in this band will be assigned for low power wireless microphones in accordance with the provisions of § 90.265.

(13) Frequencies in this band are available only for one-way paging operations in accordance with § 90.494.

(14) The frequencies available for use at operational-fixed stations in the band 72-76 are listed in § 90.257(a)(1). These frequencies are shared with other services and are available only in accordance with the provisions of § 90.257.

(15) This frequency is not available in the 150-170 MHz band until August 18, 1996. This frequency will be assigned with an authorized bandwidth not to exceed 11.25 kHz. In the 450-470 MHz band, secondary telemetry operations pursuant to § 90.238(e) will be authorized on this frequency.

(16) Subpart T contains rules for assignment of frequencies in the 220-222 MHz band.

(17) This frequency is not available until August 18, 1996. After August 18, 1996 this frequency will be assigned with an authorized bandwidth not to exceed 6 kHz.

(18) Assignment of frequencies in this band are subject to the provisions of § 90.173

(19) This frequency is available for systems first licensed prior to August 18, 1995. No new systems will be authorized after August 18, 1995, but prior authorized systems may be modified, expanded, and renewed.

(d) Limitation on number of frequencies assignable. Normally only one frequency, or pair of frequencies in the paired frequency mode of operation, will be assigned for mobile service operations by a single applicant in a given area. The assignment of an additional frequency or pair of frequencies will be made only upon a satisfactory showing of need, except that: (See also § 90.253).

(1) [Reserved]

(2) Frequencies in the 25-50 MHz, 150-170 MHz, 450-512 MHz and 902-928 MHz bands may be assigned for the operation of Location and Monitoring Service (LMS) systems in accordance with the provisions of subpart M of this part, notwithstanding this limitation.

(3) The frequency band 33.00-33.01 MHz may be used for developmental operation subject to the provisions of subpart Q. Any type of emission other than pulsed emission may be used if the bandwidth occupied by the emission is contained within the assigned frequency band.

(e) In addition to the frequencies shown in the frequency table of this section, frequencies in the 421-430 MHz band are available in the Detroit, Cleveland, and Buffalo areas in accordance with the rules in §§ 90.273 through 90.281.
