The first wireless telegraph radio, developed by Guglielmo Marconi in the late 19th century, was used to transmit Morse Code signals over long distances without the need for physical wires. It operated by generating radio waves that could be received by a receiver equipped with a coherer, which detected the signals. This technology enabled real-time communication for maritime and military applications, significantly improving long-distance communication capabilities. The successful use of wireless telegraphy marked the beginning of the radio era, paving the way for future advancements in communication.

Wireless telegraphy is an expression describing early radio telegraph communication, particularly between 1880 and 1920, before the term radio was used.
Which year did guglielmo marconi invent the wireless telegraph?
We know that in St. Louis, Missouri, Nikola Tesla made the first public demonstration of a modern wireless system in 1893 but The Marconi Company Ltd. was founded by Guglielmo Marconi in 1897 as The Wireless Telegraph & Signal Company. He also a patent for the radio which taken away from him a given to Nikola Tesla after studies showed he came with the radio before Marconi and that Marconi used 17 patents from Tesla to achieve his radio which a short range radio compared to Tesla's long range radio.
When were radio stations first licensed in Australia?
Radio is a way of transmitting signals without wires. It uses electromagnetic radiation to transmit sounds made in one place to listeners in many places. Radio is also known as 'wireless telegraphy', or 'wireless', as earlier methods for sending signals (such as the telegraph and telephone) used wires. Australia adopted radio for communications at sea and in lighthouses, and wireless telegraphy gradually replaced the Overland Telegraph which had been completed in 1872.
