§  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 § 2.106) and the non-Federal Table of
   Frequency Allocations (non-Federal Table, column 5 of § 2.106). The
   United States Table is based on the Region 2 Table because the relevant
   area of jurisdiction is located primarily in Region 21 (i.e., the 50
   States, the District of Columbia, the Caribbean insular areas,2 and
   some of the Pacific insular areas).3 The Federal Table is administered
   by NTIA4 and the non-Federal Table is administered by the Federal
   Communications Commission (FCC).5

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

   2The operation of stations in the U.S. insular areas located in Region
   2 is generally governed by the United States Table. The U.S. insular
   areas located in Region 2 are comprised of the Caribbean insular areas
   and two of the eleven Pacific insular areas. The Caribbean insular
   areas are Puerto Rico, the United States Virgin Islands, and Navassa
   Island. The Pacific insular areas located in Region 2 are Johnston
   Atoll and Midway Atoll.

   3The operation of stations in the Pacific insular areas located in
   Region 3 is 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.

   (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 allocations6 in columns 4 and 5 of § 2.106
   correspond to the terms in the ITU Radio Regulations.

   6The radio services are defined in 47 CFR 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. (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 frequency
   band in column 4, then the Federal sector has no access to that band
   except as provided for by § 2.103. If there is no service or footnote
   indicated for a frequency band in column 5, then the non-Federal sector
   has no access to that band except as provided for by § 2.102.

   (2) When the type of service(s) permitted and any applicable
   footnote(s) are the same for a frequency band in the Federal Table and
   the non-Federal Table, columns 4 and 5 are merged, indicating that the
   frequency band is shared between the Federal and non-Federal sectors
   under the same conditions.

   (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 number consisting of "5." followed by one or more
   digits,7 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.

   7In some cases, a letter, or letters, may be appended to the digit(s)
   of a footnote number in order to preserve the sequential order.

   (ii) Any footnote consisting of the letters "US" followed by one or
   more digits,7 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,7 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 letters "G" followed by one or more
   digits,7 e.g., G2, denotes a stipulation applicable only to Federal
   operations. Federal footnotes appear solely in the Federal Table
   (column 4).

   (6) The coordinates of latitude and longitude that are listed in United
   States, Federal, and non-Federal footnotes are referenced to the North
   American Datum of 1983 (NAD 83).

   (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 to the pertinent FCC Rule
   part (column 6 of § 2.106) or, where greater specificity would be
   useful, to the pertinent subpart. 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 § 2.106. The exact use that can be
   made of any given frequency or frequency band (e.g., channeling plans,
   allowable emissions, etc.) is given in the FCC Rule part(s) so
   indicated. The FCC Rule parts in this column are not allocations, may
   apply to only a portion of a band, and are provided for informational
   purposes only. This column also may contain explanatory notes for
   informational purposes only.

   Note 1 to paragraph (e): The radio frequency devices authorized
   pursuant to 47 CFR part 15 are not based on allocated radio services.
   In the Allocation Table, the cross references to part 15 are used to
   note those frequency bands that are most typically associated with
   unlicensed use.

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