Wireless Telegraphy

Wireless telegraphy is a method of communication that transmits messages over long distances without wires, using radio waves. Invented in the late 19th century, it allows sending and receiving coded messages, typically in Morse code, through the air. This technology revolutionized communication, especially for maritime and military purposes, as it enables instant communication over vast distances. Wireless telegraphy laid the groundwork for modern wireless communications, including radio, television, and mobile phones, by demonstrating the potential of transmitting information without physical connections.
