Extracts from the Radio Regulations (RR)

(Edition of 200 1)

SECTION I - ARTICLES (Volume I ofthe RR)

SECTION II - APPENDICES (Volume 2 of the RR)

SECTION III - RESOLUTIONS (Volume 3 ofthe RR)

(Volume 4 of the RR)

Note by the Secretariat

This revision of the Radio Regulations, complementing the Constitution and the Convention ofthe International Telecommunication Union, incorporates the decisions of the World Radiocom-munication Conferences of 1995 (WRC-95), of 1997 (WRC-97) and of 2000 (WRC-2000) Themajority of the provisions of these Regulations shall enter into force as from 1 January 2002; theremaining provisions shall apply as from the special dates of application indicated in Article 59

of the revised Radio Regulations

In preparing the Radio Regulations, edition of 2001, the Secretariat corrected the typographicalerrors that were drawn to the attention ofWRC-2000 and which were approved by WRC-2000

In accordance with the decisions of WRC-2000, this edition uses a new numbering scheme,

which consists, inter alia, in abolishing the prefix "8" in front of the provision numbers, Article

numbers and Appendix numbers The numbering scheme is identical to the previous edition ofthe Radio Regulations, but without the prefix "8" in front of the provision numbers, Articlenumbers and Appendix numbers In some cases, however, the prefix "8" was maintained due tohistorical reasons or for referential purposes

With respect to Article numbers, this edition follows the standard sequential numbering TheArticle numbers are not followed by any abbreviation (such as "WRC-97" or "WRC-2000").Consequently, any reference to an Article, in any of the provisions of these Radio Regulations(e.g in No 13.1 of Article 13), in the texts of the Appendices as contained in Volume 2 of thisedition (e.g in § 1 of Appendix 2), in the texts of the Resolutions included in Volume 3 of thisedition (e.g in Resolution 1(Rev.WRC-97», and in the texts of the Recommendations included

in Volume 3 of this edition (e.g in Recommendation 8), is considered as a reference to the text

of the concerned Article which appears in this edition, unless otherwise specified

With respect toprovision numbers in Articles, this edition continues to use composite numbersindicating the number of the Article and the provision number within that Article (e.g No 9.2Bmeans provision No 2B of Article 9) The abbreviation "(WRC-2000)" or "(WRC-97)" at theend of such a provision means that the relevant provision was modified or added by WRC-2000

or by WRC-97, as applicable The absence of an abbreviation at the end of the provision meansthat the provision is identical with the provision of the simplified Radio Regulations as approved

by WRC-95, and whose complete text was contained in Document 2 of WRC-97 However, assome of the Resolutions call for the application of a provision of the Radio Regulations, thisedition of the Radio Regulations and the corresponding Resolutions contains references to threedifferents sets of provision numbers:

- provision numbers that are not preceded by the letter "8" and which follow the newnumbering scheme comprising a composite number indicating the number of the Articleand the provision number within that Article; the quoted provision number corresponds toits version in the current edition;

- provision numbers that are not preceded by the letter "8" and which follow the oldnumbering scheme of sequential numbers Their quotation was maintained in those caseswhere their application is still relevant To avoid any ambiguity, these provisions arenormally followed by the additional explication that they refer to provisions of the RadioRegulations, edition of ] 990, revised in 1994;

- provision numbers that are preceded by the letter "8"; the quoted provision numbercorresponds to the provisions of the Radio Regulations, edition of 1998, unless otherwisespecified These quotations were maintained only in those cases where justified, either forhistorical reasons, or for reference purposes (i.e., when the quoted provision is differentfrom the new provision) When the reference was maintained for historical reasons, andwhere applicable, an appropriate note by the Secretariat has been added to indicate theprovision number corresponding to the new numbering scheme

With respect to Appendix numbers, this edition follows the standard sequential numbering,

with the addition of the appropriate abbreviation after the Appendix number (such as

"(WRC-97)" or "(WRC-2000)"), where applicable As a rule, any reference to an Appendix, inany of the provisions of these Radio Regulations, in the texts of the Appendices as contained inVolume 2 of this edition, in the texts of the Resolutions and of the Recommendations included inVolume 3 of this edition, is presented in the standard manner (e.g "Appendix 30 (WRC-2000)")

if not explicitly described in the text (e.g Appendix 4 as modified by WRC-2000) Simplereferences to Appendix numbers, where the number is preceded by the letter "8" but without anabbreviation at the end (such as "Appendix 830"), correspond to the version of the concernedAppendix in the 1998 edition of the Radio Regulations, unless otherwise specified Simplereferences to Appendix numbers, where the number is not preceded by the letter "8" and without

an abbreviation at the end (such as "Appendix 19"), correspond to the current version of theconcerned Appendix, as it appears in this edition of the Radio Regulations In the texts ofAppendices that were partially modified by WRC-2000, the provisions that were modified byWRC-2000 are indicated with the abbreviation "(WRC-2000)") at the end of the concerned text

The abolishing of the prefix "8" in front of the Article numbers, provision numbers andAppendix numbers in this edition of the Radio Regulations is purely an editorial matter as there

is equivalence between the provisions of the Radio Regulations (edition of 2001) which do notinclude the prefix "8" and the provisions of the Radio Regulations (edition of 1998) whichinclude the prefix "8", excepting the case of provisions which contain the abbreviation

"(WRC-2000)") at the end of the provision

Also, from the regulatory point of view, the cross-references to provisions which include theprefix "8" in the Resolutions appearing in the Final Acts of WRC-2000, as well as in theResolutions appearing in Volume 3 of the ] 998 edition that have not been modified byWRC-2000, and the cross-references to provisions without the prefix "8" which appear in theResolutions contained in this edition, are considered equivalent
