Technical interface regulations

Technical interface regulations (RIR) define the requirements for the frequency use by radiocommunication equipment in the frequency range up to 3000 GHz. RIR include the technical parameters, the frequency bands as well as the licensing regime (in Switzerland) respectively the obligation for individual frequency assignment (in 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 making available on the market of radiocommunication equipment in Switzerland and in the Principality of Liechtenstein.

Basis document
The basis document RIR0000 explains the structure of the technical interface regulations and the content of the used parameter fields.

Draft for future interface regulations (Draft)
Draft for future interface regulations (RIR) are published for information purposes. They do not have the force of law and their contents can still undergo important modifications until officially released.


The interface regulations will be notified to the World Trade Organization (WTO) and to the European Free Trade Association (EFTA) at the latest 3 months before their scheduled date of entry into force.
