Guglielmo Marconi was born in 1874 right into a wealthy family in Bologna, Italy, and educated by personal tutors. He developed an curiosity in science, significantly the work of German physicist Heinrich Hertz on the transmission of electromagnetic waves by the air. Although he failed the doorway exam on the University of Bologna, Marconi began experimenting with wi-fi telegraphy on his personal in 1894. He discovered that by connecting his transmitter and receiver to the earth (grounding them), after which rising the height of the antenna, he might lengthen the range of the sign.

In November, 1897, Marconi and Mr. Kemp rigged up a stout mast at the Needles on the Isle of Wight, 120 toes high, and supported a wire from the top by an insulated fastening. Then, having connected the lower finish of this wire with a transmitter, they put out to sea in a tugboat, taking with them a receiving-instrument linked to a wire that hung from a sixty-foot mast. Their object was to see at what distance from the Needles they might get signals. For months, by way of storm and gale, they stored at this work, leaving the Needles farther and farther behind them as details in the devices had been improved, till by the New Year they had been in a position to get indicators clear across to the mainland. Forthwith a everlasting station was arrange there-first at Bournemouth, fourteen miles from the Needles, however subsequently moved to …
