The story of electromagnetic spectrum operations (EMSO) continues with the discovery of wireless telegraphy and how it forever changed the global landscape. In this episode, we trace the life of Guglielmo Marconi through his dreams and determination as a young engineer who believed the experiments of Heinrich Hertz could change the world, to the shrewd businessman who ushered us into the Dawn of the Electronic Age. From experiments at home in Italy to helping nations communicate wirelessly across the Atlantic Ocean, Marconi helped the world become globally interconnected in a way that many thought impossible at the turn of the 20th Century.
