Radiocommunications Bureau, BR
Study Groups The work of the Study Groups is governed by the ITU-R Resolutions, in particular Resolution ITU-R 1, and WRC agenda items requesting preparatory studies The studies are driven by Contributions from the Membership. Each Study Group carries out studies, adopting Recommendations and Questions, as well as approving Reports, Decisions, Opinions and Handbooks, on radiocommunication matters under its mandate. These are the technical, operational and procedural bases for decisions taken at WRCs and for efficient use of the radio spectrum and the geostationary- satellite orbit.
