Summary of the Order

1. By this action, the Commission's Office of Engineering and Technology and Office of Managing Director amends the Table and supporting sections of the Commission's rules in order to more clearly display the Table and to assist the Federal Register staff by making it easier for them to maintain the Table in the Code of Federal Regulations. We take this action with the concurrence of the National Telecommunications and Information Administration. We also take this opportunity to make the following types of non-substantive amendments:

• The International Table in the Commission's rules is updated to reflect the [International] Table of Frequency Allocations as it is found in the 1998 International Telecommunication Union Radio Regulations;
• International footnotes in the United States Table that have not been substantively revised are re-numbered;
• Expired footnotes or portions of footnotes are removed from the United States Table;
• The special-use frequencies column of the Table is removed; and
• Various typographical errors and omissions are corrected.

As a by-product of this action, we will now be able to place the Table on the Commission's web site and to update the on-line Table shortly after any amendments to the Table have been released.^[1] This ministerial action does not make any substantive change to any licensee's legal rights and responsibilities.

PART 2—FREQUENCY ALLOCATIONS AND RADIO TREATY MATTERS; GENERAL RULES AND REGULATIONS

1. The authority citation for part 2 continues to read as follows:

Authority: 47 U.S.C. 154, 302, 303, 307, 336 and 337, unless otherwise noted.

2. Paragraph 2.100 is revised to read as follows:

§ 2.100

International regulations in force.

The provisions of the Radio Regulations (Geneva, 1998) apply provisionally as from January 1, 1999, unless an earlier date is specified in Article S59.

3. Section 2.104 is revised to read as follows:

§ 2.104

International Table of Frequency Allocations.

(a) The International Table of Frequency Allocations is subdivided into the Region 1 Table (column 1 of § 2.106), the Region 2 Table (column 2 of § 2.106), and the Region 3 Table (column 3 of § 2.106). The International Table is included for informational purposes only.

(b) Regions. For the allocation of frequencies the International Telecommunication Union (ITU) has divided the world into three Regions ^[1] as shown in Figure 1 of this section and described as follows:

(1) Region 1. Region 1 includes the area limited on the east by line A (lines A, B and C are defined below) and on the west by line B, excluding any of the territory of the Islamic Republic of Iran which lies between these limits. It also includes the whole of the territory of Armenia, Azerbaijan, Russian Federation, Georgia, Kazakstan, Mongolia, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the north of Russian Federation which lies between lines A and C.

(2) Region 2. Region 2 includes the area limited on the east by line B and on the west by line C.

(3) Region 3. Region 3 includes the area limited on the east by line C and on the west by line A, except any of the territory of Armenia, Azerbaijan, Russian Federation, Georgia, Kazakstan, Mongolia, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the north of Russian Federation. It also includes that part of the territory of the Islamic Republic of Iran lying outside of those limits.

(4) The lines A, B and C are defined as follows:

(i) Line A. Line A extends from the North Pole along meridian 40° East of Greenwich to parallel 40° North; thence by great circle arc to the intersection of meridian 60° East and the Tropic of Cancer; thence along the meridian 60° East to the South Pole.

(ii) Line B. Line B extends from the North Pole along meridian 10° West of Greenwich to its intersection with parallel 72° North; thence by great circle arc to the intersection of meridian 50° West and parallel 40° North; thence by great circle arc to the intersection of meridian 20° West and parallel 10° South; thence along meridian 20° West to the South Pole.

(iii) Line C. Line C extends from the North Pole by great circle arc to the intersection of parallel 65° 30′ North with the international boundary in Bering Strait; thence by great circle arc to the intersection of meridian 165° East of Greenwich and parallel 50° North; thence by great circle arc to the intersection of meridian 170° West and parallel 10° North; thence along parallel 10° North to its intersection with meridian 120° West; thence along meridian 120° West to the South Pole.

(c) Areas. To further assist in the international allocation of the radio spectrum, the ITU has established five special geographical areas and they are defined as follows:

(1) The term “African Broadcasting Area” means:

(i) African countries, parts of countries, territories and groups of territories situated between the parallels 40° South and 30° North;

(ii) Islands in the Indian Ocean west of meridian 60° East of Greenwich, situated between the parallel 40° South and the great circle arc joining the points 45° East, 11° 30′ North and 60° East, 15° North; and

(iii) Islands in the Atlantic Ocean east of line B, situated between the parallels 40° South and 30° North.

(2) The “European Broadcasting Area” is bounded on the west by the western boundary of Region 1, on the east by the meridian 40° East of Greenwich and on the south by the parallel 30° North so as to include the northern part of Saudi Arabia and that part of those countries bordering the Mediterranean within these limits. In addition, Iraq, Jordan and that part of the territory of Syria, Turkey and Ukraine lying outside the above limits are included in the European Broadcasting Area.

(3) The “European Maritime Area” is bounded to the north by a line extending along parallel 72° North from its intersection with meridian 55° East of Greenwich to its intersection with meridian 5° West, then along meridian 5° West to its intersection with parallel 67° North, thence along parallel 67° North to its intersection with meridian 32° West; to the west by a line extending along meridian 32° West to its intersection with parallel 30° North; to the south by a line extending along parallel 30° North to its intersection with meridian 43° East; to the east by a line extending along meridian 43° East to its intersection with parallel 60° North, thence along parallel 60° North to its intersection with meridian 55° East and thence along meridian 55° East to its intersection with parallel 72° North.

(4) The “Tropical Zone” (see Figure 1 of this section) is defined as:

(i) The whole of that area in Region 2 between the Tropics of Cancer and Capricorn.

(ii) The whole of that area in Regions 1 and 3 contained between the parallels 30° North and 35° South with the addition of:

(A) The area contained between the meridians 40° East and 80° East of Greenwich and the parallels 30° North and 40° North; and

(B) That part of Libya north of parallel 30° North.

(iii) In Region 2, the Tropical Zone may be extended to parallel 33° North, subject to special agreements between the countries concerned in that Region.

(5) A sub-Region is an area consisting of two or more countries in the same Region.

(d) Categories of services and allocations. (1) Primary and secondary services. Where, in a box of the International Table in § 2.106, a band is indicated as allocated to more than one service, either on a worldwide or Regional basis, 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; and

(ii) Services the names of which are printed in “normal characters” (example: Mobile); these are called “secondary” services (see paragraph (d)(3) of this section).

(2) Additional remarks shall be printed in normal characters (example: MOBILE except aeronautical mobile).

(3) 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.

(4) Where a band is indicated in a footnote of the International Table as allocated to a service “on a secondary basis” in an area smaller than a Region, or in a particular country, this is a secondary service (see paragraph (d)(3) of this section).

(5) Where a band is indicated in a footnote of the International Table as allocated to a service “on a primary basis”, in an area smaller than a Region, or in a particular country, this is a primary service only in that area or country.

(e) Additional allocations. (1) Where a band is indicated in a footnote of the International Table as “also allocated” to a service in an area smaller than a Region, or in a particular country, this is an “additional” allocation, i.e. an allocation which is added in this area or in this country to the service or services which are indicated in the International Table.

(2) If the footnote does not include any restriction on the service or services concerned apart from the restriction to operate only in a particular area or country, stations of this service or these services shall have equality of right to operate with stations of the other primary service or services indicated in the International Table.

(3) If restrictions are imposed on an additional allocation in addition to the restriction to operate only in a particular area or country, this is indicated in the footnote of the International Table.

(f) Alternative allocations. (1) Where a band is indicated in a footnote of the International Table as “allocated” to one or more services in an area smaller than a Region, or in a particular country, this is an “alternative” allocation, i.e. an allocation which replaces, in this area or in this country, the allocation indicated in the Table.

(2) If the footnote does not include any restriction on stations of the service or services concerned, apart from the restriction to operate only in a particular area or country, these stations of such a service or services shall have an equality of right to operate with stations of the primary service or services, indicated in the International Table, to which the band is allocated in other areas or countries.

(3) If restrictions are imposed on stations of a service to which an alternative allocation is made, in addition to the restriction to operate only in a particular country or area, this is indicated in the footnote.

(g) Miscellaneous provisions. (1) Where it is indicated that a service may operate in a specific frequency band subject to not causing harmful interference, this means also that this service cannot claim protection from harmful interference caused by other services to which the band is allocated under Chapter SII of the international Radio Regulations.

(2) Except if otherwise specified in a footnote, the term “fixed service”, where appearing in the International Table, does not include systems using ionospheric scatter propagation.

(h) Description of the International Table of Frequency Allocations. (1) The heading of the International Table includes three columns, each of which corresponds to one of the Regions (see paragraph (b) of this section). Where an allocation occupies the whole of the width of the Table or only one or two of the three columns, this is a worldwide allocation or a Regional allocation, respectively.

(2) The frequency band referred to in each allocation is indicated in the left-hand top corner of the part of the Table concerned.

(3) Within each of the categories specified in paragraph (d)(1) of this section, services are listed in alphabetical order according to the French language. The order of listing does not indicate relative priority within each category.

(4) In the case where there is a parenthetical addition to an allocation in the International Table, that service allocation is restricted to the type of operation so indicated.

(5) The footnote references which appear in the International Table below the allocated service or services apply to the whole of the allocation concerned.

(6) The footnote references which appear to the right of the name of a service are applicable only to that particular service.

(7) In certain cases, the names of countries appearing in the footnotes have been simplified in order to shorten the text.

Figure 1 to § 2.104—Map

4. Section 2.105 is revised to read as follows.

§ 2.105

United States Table of Frequency Allocations.

(a) The United States Table of Frequency Allocations (United States Table) is subdivided into the Federal Government Table of Frequency Allocations (Federal Government Table, column 4 of § 2.106) and the Non-Federal Government Table of Frequency Allocations (Non-Federal Government 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 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 Government Table is administered by the National Telecommunications and Information Administration (NTIA) ^[5] , whereas the Non-Federal Government Table is administered by the Federal Communications Commission (FCC).^[6]

(b) In the United States, radio spectrum may be allocated to either Federal government or non-Federal government 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 government FIXED, non-Federal government MOBILE]. The terms used to designate categories of services and allocations ^[7] in columns 4 and 5 of § 2.106 correspond to the terms employed by the International Telecommunication Union (ITU) in the international Radio Regulations.

(c) Category of services. (1) Any segment of the radio spectrum may be allocated to the Federal government and/or non-Federal government 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 government and column 5 for non-Federal government, 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 either column 4 or 5, then the Federal government or the non-Federal government sector, respectively, has no access to that band except as provided for by § 2.102.

(2) When the Federal Government and Non-Federal Government Tables 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 Government 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 “S5.” followed by one or more digits, e.g., S5.53, or any footnote not prefixed by a letter, e.g., 459, denotes an international footnote. Where an international footnote is applicable, without modification, to the United States Table, the footnote appears in the United States Table (columns 4 and 5) and denotes a stipulation affecting both the Federal Government Table and the Non-Federal Government Table. If, however, an international footnote pertains to a service allocated only for Federal government or non-Federal government use, the international footnote will be placed only in the affected Table. For example, “AMATEUR S5.142” shall be shown only in the Non-Federal Government Table.

(ii) Any footnote consisting of the letters US followed by one or more digits, e.g., US7, denotes a stipulation affecting both the Federal Government Table and the Non-Federal Government Table.

(iii) Any footnote consisting of the letters NG followed by one or more digits, e.g., NG2, denotes a stipulation applicable only to the Non-Federal Government 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 the Federal Government Table (column 4).

(6) If a frequency or frequency band has been allocated to a radiocommunication service in the Non-Federal Government Table, then a cross reference may be added for the pertinent FCC Rule part (column 6 of § 2.106). For example, the 849-851 MHz band is allocated to the non-Federal government aeronautical mobile service, 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 the Table. 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.

5. Section 2.106 is amended as follows:

a. The Table proceeding the international footnotes is revised and shall begin on a left-hand page.

b. The international footnotes section is revised.

c. United States footnotes US7, US78, US221, US256, US257, US296, US303, US311, US319, and US322 are revised.

d. United States footnotes US272, US284, US326, and US341 are removed.

e. The heading to the list of “Non-Government (NG) Footnotes” is revised and in the parenthetical following the heading revise “non-Government” to read “non-Federal Government”.

f. Non-Federal government footnotes NG47, NG102, NG120, NG124, NG128, and NG147 are revised.

g. Non-Federal government footnotes NG133, NG139, NG140, and NG154 are removed.

h. The heading to the list of “Government (G) Footnotes” is revised and in the parenthetical following the heading revise “Government” to read “Federal Government”.

i. Federal government footnotes G101 and G119 are removed.

j. Federal government footnote G106 is revised.

The revisions and additions read as follows:

§ 2.106

Table of Frequency Allocations.

International Footnotes

Note:

The International Telecommunication Union has recently re-numbered international footnotes using the “S” numbering scheme and has substantively revised the text of certain of these international footnotes. These international footnotes shall be listed immediately below this note in I. Until such time as the Commission has considered the substantively revised international footnotes that have previously been adopted domestically, the old international footnotes shall apply in the United States. These footnotes appear immediately after footnote S5.565 in II.
