A coherer receiver transmitted the pulses to a register that printed the sequences onto paper so they could be read. At first, the transmission distance was only the length of a room, but Marconi then moved his operation outdoors and achieved successful transmissions across longer distances. In search of a wider audience for his new technology, Marconi traveled to England in to give a series of presentations to the British government.
He filed for his first British patent— Patent No. Marconi also demonstrated for the first time that wireless communication could be achieved across open water—he successfully sent a message across the Bristol Channel to a distance of four miles. With patent in hand, Marconi launched the Marconi Company which would have several other names throughout the 20th century. Marconi earned widespread attention for his discoveries, but there remained a fair number of skeptics. On December 12, , Marconi claimed that he made the first successful transatlantic radio transmission between Cornwall, England, and St.
The message? The letter S in Morse code. Other scientists, however, questioned whether radio waves could travel beyond the horizon due to the curvature of the Earth. Marconi did further tests that showed that radio waves were interacting with the ionosphere, a layer of the atmosphere that is ionized by solar radiation, which bounces radio waves back towards Earth.
Because the composition of the ionosphere changes depending on the presence or absence of the sun, some radio waves travel farther by night than during the day. By , the Marconi Company had built permanent wireless stations at Glace Bay in Nova Scotia and Cape Cod, Massachusetts to complement those in Europe, forever making transatlantic communication possible. In a powerful demonstration of his invention, Marconi radioed a greeting from President Theodore Roosevelt across the Atlantic to King Edward VII of England on January 18, —the first successful transmission of a complete message.
