The International Telecommunication Union Radiocommunication Sector, or ITU-R, is a specialized agency of the United Nations responsible for managing the global radio-frequency spectrum and satellite orbits. It plays a crucial role in coordinating international efforts to ensure that radio communications operate smoothly and without interference. This includes setting technical standards and regulations that countries must follow. ITU-R also facilitates cooperation among its member states to address emerging challenges in radiocommunication, such as the increasing demand for wireless services and the need for sustainable use of the radio spectrum. By promoting best practices and sharing knowledge, ITU-R helps to enhance global communication networks and services.
