* 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.                    

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

150.8375, 150.845, 150.8525, 150.860, 150.8675, 150.875, 150.8825, 
150.890, or 150.8975 MHz may be assigned to the same licensee in a given

persons who provide to the general public an emergency road service for 
disabled vehicles: Except that; at the discretion of the Commission this 
frequency may also be operated by or on behalf of associations of owners 
of private automobiles upon a showing that all other frequencies 
available for assignment to such stations are currently assigned to 
other stations for use in the area concerned and that the use of the 
requested frequency, in each case, will be less likely to result in 
mutual harmful interference that would the use of a frequency otherwise 
available to the station.
    (6) Only one of the frequencies 157.470, 157.4775, 157.485, 
157.4925, 157.500, 157.5075, 157.515, or 157.5225 MHz may be assigned to

    (7) The requirements for secondary fixed use of frequencies in this 
band are set forth in Sec. 90.261.
    (8) This frequency is available for assignment to stations which are 
operated by or on behalf of associations of owners of private 
automobiles for single-frequency operation.
    (9) Subpart L contains rules for assignment of frequencies in the

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.
    (14) Use of this frequency band is limited to developmental 
operation and is subject to the provisions of subpart Q.
    (15) Frequencies in this band are available only for one-way paging 
operations in accordance with Sec. 90.494.
    (16) The frequencies available for use at operational-fixed stations

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.
    (19) Subpart T contains rules for assignment of frequencies in the 
220-222 MHz band.
    (20) 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.
    (21) Assignment of frequencies in this band are subject to the 
provisions of Sec. 90.173
    (22) This frequency will be authorized a channel bandwidth of 25 
kHz.
    (23) 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

    (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: (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.
    (f) 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
