World Radiocommunication Conference

World Radiocommunication Conference (WRC) is organized by ITU to review, and, as necessary, revise the Radio Regulations, the international treaty governing the use of the radio-frequency spectrum and the geostationary-satellite and non-geostationary-satellite orbits. It is held every three to four years. Prior to 1993 it was called the World administrative radio conference WARC; in 1992 at an Additional Plenipotentiary Conference in Geneva the ITU was restructured and later conferences became the WRC.

At the 2015 conference (WRC-15), the ITU deferred their decision on whether to abolish the leap second to 2023.

The next World Radiocommunication Conference (WRC-19) will take place from 28 October to 22 November 2019.
