Le présent document spécifie les exigences essentielles des systèmes radioélectriques fixes numériques (DFRS) point à point fonctionnant en duplex intégral à répartition en fréquence (FDD) dans les bandes de fréquences où est appliquée la planification coordonnée liaison par liaison des fréquences. Il est destiné à couvrir les dispositions de la Directive R&TTE, Article 3.2, qui stipule que "...les équipements hertziens doivent être construits de telle sorte qu'ils utilisent efficacement le spectre attribué aux communications radio terrestres ou spatiales ainsi que les ressources orbitales pour éviter les interférences dommageables".

The accuracy of direction finding systems is an important consideration to regulatory authorities and others who have to locate signals. It is often difficult to compare different systems due to a number of factors, such as the particular system basic design architecture, typical use/purpose, size requirements, installation requirements, and other issues. In order to facilitate some basic comparisons between different direction finding (DF) systems, this Recommendation provides some guidance on standard methods of testing DF accuracy and reporting results.

This Recommendation describes the priority that should be given to interference detected in the band 406-406.1 MHz by Administrations and their monitoring authorities, because interference impairs the detection and geolocation of actual distress beacons. Cospas-Sarsat is an international satellite-based search and rescue (SAR) distress alert system which detects and locates emergency beacons activated by aircraft, ships and backcountry hikers in distress worldwide. The Recommendation provides additional references to the ITU Monitoring programme for 406 MHz, as well as references to Report ITU-R SM.2258.
