Cornwall has played an important role in the history of telecommunication, especially in the development of wireless communication. The region’s strategic location on the western coast of England made it an ideal location for experimenting with long-range wireless communication.
Guglielmo Marconi, an Italian inventor and electrical engineer, is widely regarded as the father of wireless communication. In 1897, he established the world’s first wireless communication station at The Lizard, a peninsula on the southern coast of Cornwall.
Marconi’s experiments at The Lizard were conducted using a high-powered transmitter and a simple receiver consisting of a coherer, a glass tube filled with metal filings that could detect radio waves. Marconi was able to send Morse code messages over a distance of several miles, proving that wireless communication was possible over long distances.
Following his success at The Lizard, Marconi continued to conduct experiments in Cornwall. In 1900, he established a wireless communication station at Poldhu, on the western coast of Cornwall. From here, he was able to send wireless signals across the Atlantic, making history as the first person to transmit a wireless signal across the ocean.
The Poldhu station continued to play a key role in the development of wireless communication, and in 1901 Marconi used it to send the first transatlantic radio message. The message was sent from Poldhu to Signal Hill in St. John’s, Newfoundland, Canada, a distance of approximately 2,100 miles.
Marconi’s success in Cornwall helped to establish the practicality of wireless communication, paving the way for the development of modern telecommunications. Today, the Poldhu site is home to a museum dedicated to Marconi’s work, and the Lizard still hosts a station operated by the National Coastwatch Institution.
