The main task of the 1959 Administrative Radio Conference was to revise the Radio Regulations and Additional Radio Regulations of Atlantic City, 1947. However, this was complicated due to the major developments in radiocommunication that had taken place in the intervening period between 1947 and 1959. After four months, and despite a variety of challenges, the Conference managed to successfully reach acceptable solutions with respect to the over 6000 proposals submitted to revise the Radio Regulations.
