Technical interface regulations (RIR) define the requirements for the frequency use up to 3000 GHz by radiocommunication equipment. RIR include the technical parameters, the frequency bands as well as the licensing regime in Switzerland and the Principality of Liechtenstein.
RIR indicate the technical standards which, when they are fulfilled, pose a presumption of conformity to the essential requirements. The fulfilling of the essential requirements constitutes one of the conditions for offering and placing on the market of radiocommunication equipment in Switzerland and in the Principality of Liechtenstein.
The basis document RIR0000 explains the structure of the technical interface regulations and the content of the used parameter fields.
