History of wireless technology Timeline

“The world’s first wireless telephone conversation occurred in 1880, when Alexander Graham Bell and Charles Sumner Tainter invented and patented the photophone, a telephone that conducted audio conversations wirelessly over modulated light beams (which are narrow projections of electromagnetic waves).”

The term wireless has been used twice in communications history, with slightly different meaning. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920 .

Guglielmo Marconi developed the first wireless telegraph system in 1896 . The following year Marconi sent the world’s first ever wireless communication over open sea. The experiment witnessed a message travelled over a distance of 6 kilometres (3.7 mi).
