MDARC - Regulations

The ITU Regulations were developed from intergovernmental treaties, intended to coordinate and standardize the operation of telecommunication networks and services and to advance the development of communications technology. They form the basis for most of the planet's regional and national telecommunications laws and regulations. The Radio Regulations, cover both legal and technical issues, serving as a supranational instrument for the optimal international management of the radio spectrum.

The ITU-R Recommendations constitute a set of international technical standards developed by the Radiocommunication Sector of the ITU. They are the result of studies undertaken by Radiocommunication Study Groups.

The ITU-R Recommendations are approved by ITU Member States. Their implementation is not mandatory; however, as they are developed by experts from administrations, operators, the industry and other organizations dealing with radiocommunication matters from all over the world, they enjoy a high reputation and are implemented worldwide.
