Radiotelegraphy
Radiotelegraphy is a method of communication that uses radio waves to send and receive messages in Morse code. Developed in the late 19th century, it allows information to be transmitted over long distances without wires. Operators use a transmitter to send coded signals, which are picked up by a receiver. Radiotelegraphy was crucial for maritime communication and emergency signaling, making it easier for ships to communicate with each other and with shore stations. Though largely replaced by voice communication and digital methods today, it laid the groundwork for modern wireless communication technologies.
