Frequency Allocations

Frequency bands (slices of the spectrum) are allocated to the different services either worldwide (worldwide allocation) or regionally (regional allocation) - (Nos. 5.23-5.33). Band allocations are set out in the Table of Frequency Allocations - Frequency Allocations of the  Amateur and Amateur Satellite Service Article 5 of the RR. To this end, the world is divided into three Regions for purposes of frequency allocation.

Each band may be allocated to one or more services, with equal or different rights. There are two categories of service, namely primary and secondary . Exceptions (additional or alternative allocations, different categories of service, etc.) or restrictions on allocations in the Table, usually geographical in a smaller area than the region (country, group of countries), are covered in "footnotes" (French: "renvoi") to the Table.

Section I. Regions

5.2    For the allocation of frequencies the world has been divided into three Regions as shown on the following map and described in Nos. 5.3 to 5.9:

REM See also List of  ITU member states by Regions (XR1, 2 or 3).

5.3   Region 1 (XR1):   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, Georgia, Kazakhstan, Mongolia, Uzbekistan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the north of Russia which lies between lines A and C.

5.4   Region 2 (XR2):   Region 2 includes the area limited on the east by line B and on the west by line C.

5.5   Region 3 (XR3):   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, Georgia, Kazakhstan, Mongolia, Uzbekistan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan, Turkey and Ukraine and the area to the north of Russia. It also includes that part of the territory of the Islamic Republic of Iran lying outside of those limits.

5.6     The lines A, B and C are defined as follows:

5.7    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.

5.8   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.

5.9   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.


Section II. Categories of Services and Allocations

5.23   Primary and Secondary Services

5.24   1) Where, in a box of the Table in Section IV of this Article, 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:

5.25   a) services the names of which are printed in "capitals" (example: FIXED); these are called "primary" services;

5.26   b) services the names of which are printed in "normal characters" (example: Mobile); these are called "secondary" services (see Nos. 5.28 to 5.31).

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

5.28   3) Stations of secondary service:

5.29   a) 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;

5.30   b) 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;

5.31   c) can claim protection, however, from harmful interference from stations of a same or other secondary service(s) to which frequencies may be assigned at a later date;

5.32    4) Where a band is indicated in a footnote of the 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 Nos. 5.28 to 5.31).

5.33    5) Where a band is indicated in a footnote of the 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.

5.34   Additional Allocations

5.35    1) Where a band is indicated in a footnote of the 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 Table (see No. 5.36).

5.36    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 Table.

5.37    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 Table.

5.38   Alternative Allocations

5.39    1) Where a band is indicated in a footnote of the 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 (see No. 5.40).

5.40    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 Table, to which the band is allocated in other areas or countries.

5.41    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.

5.42   Miscellaneous Provisions

5.43    1) Where it is indicated in these Regulations 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 these Regulations.

5.44    2) Except if otherwise specified in a footnote, the term "fixed service", where appearing in Section IV of this Article, does not include systems using ionospheric scatter propagation.

5.45    Not used.


Section III. Description of the Table of Frequency Allocations

5.46    1) The heading of the Table in Section IV of this Article includes three columns, each of which corresponds to one of the Regions (see No. 5.2). 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.

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

5.48    3) Within each of the categories specified in Nos. 5.25 and 5.26, services are listed in alphabetical order according to the French language. The order of listing does not indicate relative priority within each category.

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

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

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

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