Wireless telegraphy
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type of radio transmission during the first few decades of radio, called the "wireless telegraphy era" up until World War I, when the development of amplitude modulation (AM) radiotelephony allowed sound (audio) to be transmitted by radio. Beginning about 1908, powerful transoceanic radiotelegraphy stations transmitted commercial telegram traffic between countries at rates up to 200 words per minute. Radiotelegraphy was used for long-distance person-to-person commercial, diplomatic, and military text communication throughout the first half of the 20th century. It became a strategically important capability during the two world wars since a nation without long-distance radiotelegraph stations could be isolated from the rest of the world by an enemy cutting its submarine telegraph cables. Radiotelegraphy remains popular in amateur radio. It is also taught by the military for use in emergency communications. However, commercial radiotelegraphy is obsolete.

wireless telegraphy
Wireless telegraphy refers to the transmission of telegraph signals by radio waves, a form of electromagnetic radiation. It involves the use of various types of transmitting and receiving equipment, and often, Morse code. Unlike wired telegraphy, it allows for the transfer of information without the need for a physical connection through wires or cables. Wireless telegraphy, an early form of radio communication, was first developed in the late 19th and early 20th centuries.

Wireless telegraphy
Wireless telegraphy is a historical term today that applies to early radio telegraph communication technique and practice, particularly those used during the first three decades of radio before the term radio came into use. Wireless telegraphy originated as a term to describe electrical signaling without wires to connect the endpoints. The intent was to distinguish it from conventional telegraph signaling of the day that required a wired connection between the points. The term was initially applied to a variety of competing technologies to communicate messages encoded as symbols, without wires, around the turn of the 20th century, but radio emerged as the most significant. Wireless telegraphy rapidly came to mean Morse code transmitted with Hertzian waves decades before it came to be associated with the term radio. Radiotelephony by 1920s began to displace radio telegraphy for many applications and was the basis of public broadcasting. Radiotelegraphy continued to be used for point-to-point business, governmental, and military communication, and evolved into radioteletype networks. Wireless telegraphy is still used widely today by amateur radio hobbyists where it is commonly referred to as radiotelegraphy, continuous wave, or just CW.
