What are WRCs for?
The WRCs revise the Radio Regulations (RR), an international treaty between member states of the International Telecommunication Union (ITU) aimed at facilitating fair access to the radio frequency spectrum. This regulation also covers satellite orbits (geostationary or not) and the prevention of interference between countries. The RR is the main source of law in the field of frequencies, especially for global services, whether aeronautical, satellite, maritime or scientific.
WRCs are held approximately every four years based on an agenda decided by the previous WRC.
