* The frequencies in the band 10.55-10.68 GHz are available for Digital 
  Termination Systems and for associated internodal links in the Point- 
  to-Point Microwave Radio Service. No new licenses will be issued under
  this subpart but current licenses will be renewed.                    
                                                                        

    (c) Explanation of assignment limitations appearing in the frequency 
table of paragraph (b) of this section:
    (1) This frequency is available for assignment in this service only 
to common and contract motor carriers of passengers within a single 
urban area.
    (2) This frequency is available on a shared basis with the Petroleum 
Radio Service.
    (3) This frequency is available on a shared basis with stations in

    (4) This frequency is available for assignment in this service only 
to common and contract motor carriers of passengers between urban areas.
    (5) This frequency is available for assignment in this service only 
to common and contract motor carriers of property between urban areas.
    (6) In addition to single frequency operation, this frequency is 
available to base and mobile stations for the paired frequency mode of 
operation. For two

[[Page 408]]

frequency systems, the separation between base and mobile transmit 
frequencies is 500 kHz with the base stations transmitting on the higher 
of the two frequencies.
    (7) The frequencies available for use at operational fixed stations 
in the band 72-76 MHz are listed in Sec. 90.257(a)(1). These frequencies 
are shared with other services and are available only in accordance with 
the provisions of Sec. 90.257.
    (8) This frequency is available for assignment in this service only 
to common and contract motor carriers of property.
    (9) The requirements for secondary fixed use of frequencies in this 
band are set forth in Sec. 90.261.
    (10) This frequency is shared in the Motor Carrier and Railroad 
Radio Services. It may be assigned only when all of the frequencies in 
the 450-470 MHz band allocated to the service in which the applicant is 
primarily eligible are assigned within 56 km. (35 mi.) of the proposed 
base station.
    (11) Subpart L contains rules for assignment of frequencies in the 
470-512 MHz band.
    (12) Subpart S contains rules for assignment of frequencies in the 
806-821/851-866 and 896-901/935-940 MHz bands.
    (13) Assignment of frequencies above 928 MHz for operational-fixed 
stations is governed by part 94 of this chapter.
    (14) This frequency is available to stations in this service subject 
to the provisions of Sec. 90.259.
    (15) 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.
    (16) Use of this frequency band is limited to developmental 
operation and is subject to the provisions of subpart Q.
    (17) Frequencies in this band will be assigned for low power 
wireless microphones in accordance with the provisions of Sec. 90.265.
    (18) Frequencies in this band are available only for one-way paging 
operations in accordance with Sec. 90.494.
    (19) In the State of Alaska only, the frequency 44.10 MHz is 
available for assignment on a primary basis to stations in the Common 
Carrier Rural Radio Service utilizing meteor burst communications. The 
frequency may be used by private radio stations for meteor burst 
communications on a secondary, noninterference basis. Usage shall be in 
accordance with parts 22 and 90 of this chapter. Stations utilizing 
meteor burst communications shall not cause harmful interference to 
stations of other radio services operating in accordance with the 
allocation table.
    (20) In the State of Alaska only, the frequency 44.20 MHz is 
available for assignment on a primary basis to private land mobile radio 
stations utilizing meteor burst communications. The frequency may be 
used by common carrier stations for meteor burst communications on a 
secondary, noninterference basis. Usage shall be in accordance with 
parts 22 and 90 of this chapter. Stations utilizing meteor burst 
communications shall not cause harmful interference to stations of other 
radio services operating in accordance with the allocation table.
    (21) 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 Sec. 90.238(e) will be authorized on 
this frequency.
    (22) Subpart T contains rules for assignment of frequencies in the 
220-222 MHz band.
    (23) This frequency is also used on a secondary basis for cordless 
telephones under part 15 of this chapter.
    (24) Licensing for frequencies in this band are subject to the 
provisions of Sec. 90.173.
    (25) This frequency is available for systems first licensed prior to 
August

[[Page 409]]

18, 1995. No new systems will be authorized after August 18, 1995, but 
prior authorized systems may be modified, expanded, and renewed.
    (26) This frequency is not available until August 18, 1996. After

bandwidth not to exceed 6 kHz.
    (27) Licensees as of August 18, 1995 who operate systems that are 
2.5 kHz removed from regularly assignable frequencies may continue to 
operate on a secondary, non-interference basis after August 1, 2003.
    (d) Additional frequencies available. In addition to the frequencies 
shown in the frequency table of this section, the following frequencies 
are available in this service: (See also Sec. 90.253.)
    (1) [Reserved]
    (2) Frequencies in the band 73.0-74.6 MHz may be assigned to 
stations authorized their use on or before December 1, 1961, but no new 
stations will be authorized in this band, nor will expansion of existing 
systems be permitted. (See also Sec. 90.257.)
    (3) The frequency band 33.00-33.01 MHz may be used for developmental 
operations 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.
    (4) Frequencies in the 421-430, MHz band are available in the 
Detroit, Cleveland, and Buffalo areas in accordance with the rules in 
Secs. 90.273 through 90.281.
    (e) 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:
    (1) Additional frequencies above 25 MHz may be assigned in 
connection with operation of mobile repeaters in accordance with 
Sec. 90.247, notwithstanding this limitation.
    (2) Frequencies in the 25-50, 150-170, 450-512, and 902-928 MHz
