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.

World and Regional Radio Seminars
During the study cycle, the Bureau organizes events worldwide to convey latest changes to the RadioRegulations (RR) made by a WRC and other associated Rules of Procedure (RoP).
It provides latest information on the status of the studies currently ongoing in ITU-R
Regional Radio Seminars (RRS)The BR maintains its strategy for regional outreach through the organization of RRS to visit every developing region worldwide, fostering human capacity building on the use of the radio-frequency spectrum and satellite orbits.
About 3-4 times per year, RRS are held around the world and are jointly organized with the spectrum management authorities of host countries, in close cooperation with relevant regional organizations and the ITU regional/areas offices.
The agenda is complemented with a one or two-day forum, dedicated to spectrum-related topics of particular interest to the region.
World Radio Seminars (WRS)• The BR organizes the World
Radiocommunication Seminars (WRS) on a biennial basis.
• WRS are held at ITU Geneva, every other year.
• The agenda includes theoretical sessions and some days for workshops on terrestrial and space services.
