Sec.  2.105   United States Table of Frequency Allocations.

   (a) The United States Table of Frequency Allocations (United States Table)
   is subdivided into the Federal Table of Frequency Allocations (Federal
   Table, column 4 of  Sec. 2.106) and the non-Federal Table of Frequency
   Allocations (non-Federal Table, column 5 of  Sec. 2.106). The United States Table
   is based on the Region 2 Table because the relevant area of jurisdiction is
   located primarily in Region 2 ^1 (i.e., the 50 States, the District of
   Columbia, the Caribbean insular areas, ^2 and some of the Pacific insular
   areas). ^3 ^4 The Federal Table is administered by NTIA ^5 and the
   non-Federal Table is administered by the Federal Communications Commission
   (FCC). ^6

   ^1 See 2.104(b) for definitions of the ITU Regions.

   ^2 The Caribbean insular areas are Puerto Rico, the United States Virgin
   Islands, and Navassa Island.

   ^3 The Pacific insular areas located in Region 2 are Johnston Atoll and
   Midway Atoll.

   ^4 The operation of stations in the Pacific insular areas located in Region
   3 are generally governed by the Region 3 Table (i.e., column 3 of 2.106).
   The Pacific insular areas located in Region 3 are American Samoa, Guam, the
   Northern Mariana Islands, Baker Island, Howland Island, Jarvis Island,
   Kingman Reef, Palmyra Island, and Wake Island.

   ^5 Section 305(a) of the Communications Act of 1934, as amended. See Public
   Law 102–538, 106 Stat. 3533 (1992).

   ^6 The Communications Act of 1934, as amended.

   (b) In the United States, radio spectrum may be allocated to either Federal
   or non-Federal use exclusively, or for shared use. In the case of shared
   use, the type of service(s) permitted need not be the same [e.g., Federal
   FIXED, non-Federal MOBILE]. The terms used to designate categories of
   services and allocations ^7 in columns 4 and 5 of  Sec. 2.106 correspond to the
   terms in the ITU Radio Regulations.

   ^7 The radio services are defined in  Sec. 2.1.

   (c) Category of services. (1) Any segment of the radio spectrum may be
   allocated to the Federal and/or non-Federal sectors either on an exclusive
   or shared basis for use by one or more radio services. In the case where an
   allocation has been made to more than one service, such services are listed
   in the following order:

   (i) Services, the names of which are printed in “capitals” [example: FIXED];
   these are called “primary” services;

   (ii) Services, the names of which are printed in “normal characters”
   [example: Mobile]; these are called “secondary” services.

   (2) Stations of a secondary service:

   (i) Shall not cause harmful interference to stations of primary services to
   which frequencies are already assigned or to which frequencies may be
   assigned at a later date;

   (ii) Cannot claim protection from harmful interference from stations of a
   primary service to which frequencies are already assigned or may be assigned
   at a later date; and

   (iii) Can claim protection, however, from harmful interference from stations
   of the same or other secondary service(s) to which frequencies may be
   assigned at a later date.

   (d) Format of the United States Table and the Rule Part Cross Reference
   Column. (1) The frequency band referred to in each allocation, column 4 for
   Federal operations and column 5 for non-Federal operations, is indicated in
   the left-hand top corner of the column. If there is no service or footnote
   indicated for a band of frequencies in column 4, then the Federal sector has
   no access to that band except as provided for by  Sec. 2.103. If there is no
   service or footnote indicated for a band of frequencies in column 5, then
   the non-Federal sector has no access to that band except as provided for by
    Sec. 2.102.

   (2) When the Federal Table and the non-Federal Table are exactly the same
   for a shared band, the line between columns 4 and 5 is deleted and the
   allocations are shown once.

   (3) The Federal Table, given in column 4, is included for informational
   purposes only.

   (4) In the case where there is a parenthetical addition to an allocation in
   the United States Table [example: FIXED-SATELLITE (space-to-earth)], that
   service allocation is restricted to the type of operation so indicated.

   (5) The following symbols are used to designate footnotes in the United
   States Table:

   (i) Any footnote consisting of “5.” followed by one or more digits, e.g.,
   5.53, denotes an international footnote. Where an international footnote is
   applicable, without modification, to both Federal and non-Federal
   operations, the Commission places the footnote in both the Federal Table and
   the non-Federal Table (columns 4 and 5) and the international footnote is
   binding on both Federal users and non-Federal licensees. If, however, an
   international footnote pertains to a service allocated only for Federal or
   non-Federal use, the international footnote will be placed only in the
   affected Table. For example, footnote 5.142 pertains only to the amateur
   service, and thus, footnote 5.142 is shown only in the non-Federal Table.

   (ii) Any footnote consisting of the letters “US” followed by one or more
   digits, e.g., US7, denotes a stipulation affecting both Federal and
   non-Federal operations. United States footnotes appear in both the Federal
   Table and the non-Federal Table.

   (iii) Any footnote consisting of the letters “NG” followed by one or more
   digits, e.g., NG2, denotes a stipulation applicable only to non-Federal
   operations. Non-Federal footnotes appear solely in the non-Federal Table
   (column 5).

   (iv) Any footnote consisting of the letter “G” following by one or more
   digits, e.g., G2, denotes a stipulation applicable only to Federal
   operations. Federal footnotes appear solely in the Federal Table (column 4).

   (e) Rule Part Cross References. If a frequency or frequency band has been
   allocated to a radiocommunication service in the non-Federal Table, then a
   cross reference may be added for the pertinent FCC Rule part (column 6 of
    Sec. 2.106). For example, the band 849–851 MHz is allocated to the aeronautical
   mobile service for non-Federal use, rules for the use of the 849–851 MHz
   band have been added to Part 22—Public Mobile Services (47 CFR part 22), and
   a cross reference, Public Mobile (22), has been added in column 6 of  Sec. 2.106.
   The exact use that can be made of any given frequency or frequency band
   (e.g., channelling plans, allowable emissions, etc.) is given in the FCC
   Rule part(s) so indicated. The FCC Rule parts in this column are not
   allocations and are provided for informational purposes only. This column
   also may contain explanatory notes for informational purposes only.

   (f) The Commission updates  Sec. 2.106 shortly after a final rule that revises
   that section is released. The address for the FCC Radio Spectrum Home Page,
   which includes the FCC Online Table of Frequency Allocations and the FCC
   Allocation History File, is http://www.fcc.gov/oet/spectrum/.
