The International Telecommunication Union allocates bands so that broadcasts, aircraft and phones do not jam each other The union began in 1865 as the International Telegraph Union and is the oldest body in the United Nations system. Its member states meet at World Radiocommunication Conferences, roughly every four years, to revise the table of frequency allocations that binds national regulators.
