#accaddeoggi 27 marzo 1899: prima comunicazione telegrafica internazionale

Il mondo diventa più piccolo

Le nuove frontiere sulle onde elettromagnetiche spalancate dal fisico tedesco Heinrich Hertz avevano portato Guglielmo Marconi a compiere esperimenti sulla trasmissione telegrafica senza fili. Ottenne il brevetto della sua scoperta in Gran Bretagna, dal momento che il governo italiano dell’epoca non aveva mostrato interesse.

L'obiettivo ultimo del fisico italiano era dimostrare la possibilità di trasmettere a grandi distanze e trovati i fondi necessari, impiantò le prime stazioni sperimentali fisse.

Dopo lunghi studi tentò il collegamento radiotelegrafico attraverso il canale della Manica, su una distanza di oltre cinquanta chilometri. L'esperimento avvenne il 27 marzo del 1899, tra South Foreland e la stazione francese di Wimereux, presso Boulogne-sur-Mer, e viene ricordato come la prima comunicazione radiotelegrafica stabilita tra due diversi Stati.
