Sec. 90.93  Taxicab Radio Service.

    (a) Eligibility. Persons regularly engaged in furnishing to the 
public for hire a nonscheduled passenger land transportation service 
(which may also include the occasional transport of small items of 
property) not operated over a regular route or between established 
terminals are eligible to hold authorizations in the Taxicab Radio 
Service to operate radio stations for the transmission of communications 
essential to such activities of the licensee.
    (b) Frequencies available. The following table indicates frequencies 
available for assignment to stations in the Taxicab Radio Service, 
together with the class of station(s) to which they are normally 
assigned; and the specific assignment limitations, which are explained 
in paragraph (c) of this section:

* 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 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 Sec. 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 Sec. 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 Sec. 90.265.
    (13) Frequencies in this band are available only for one-way paging 
operations in accordance with Sec. 90.494.
    (14) The frequencies available for use at operational-fixed stations 
in the band 72-76 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.
    (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 Sec. 90.238(e) will be authorized on 
this frequency.

[[Page 417]]

    (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 Sec. 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.
    (20) 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) 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 Sec. 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 
Secs. 90.273 through 90.281.
