From The Hindu, April 22, 1925: International Wireless Congress

Paris, April 20: The Juridical Section of the International Wireless Congress has resolved that the right of intellectual property recognised by the International Convention at Berne applies to wireless diffusion of all intellectual works. The Congress also approved of a series of recommendations by which specific wave lengths will be assigned to amateurs in different regions with a view to obviate confusion caused by the similarity of wave lengths.
