Wireless: From Marconi's Black-Box to the Audion by Sungook Hong,

By 1897 Guglielmo Marconi had transformed James Clerk Maxwell's theory of electromagnetic waves into a workable wireless telegraphy system, history of wireless radio and by 1907 Lee de Forest had invented the audion, a feedback amplifier history of wireless radio and oscillator that opened the way to practical radio transmission. Fifteen years after Marconi's invention, wireless had become an essential means of communication, as well as a hobby for many.This book offers a new perspective on the early days of wireless communication. Drawing on previously untapped archival evidence history of wireless radio and recent work in the history history of wireless radio and sociology of science history of wireless radio and technology, it examines the substance history of wireless radio and context of both experimental history of wireless radio and theoretical aspects of engineering history of wireless radio and scientific practices in the first years of this technology. It offers new insights into the relationship between Marconi history of wireless radio and his scientific advisor, the physicist John Ambrose Fleming (inventor of the vacuum tube). It includes the full story of the infamous 1903 incident in which Marconi's opponent Nevil Maskelyne interfered with Fleming's public demonstration of Marconi's syntonic (tuning) system at the Royal Institution by sending derogatory messages from his own transmitter. The analysis of the Maskelyne affair highlights the struggle between Marconi history of wireless radio and his opponents, the efficacy of early syntonic devices, Fleming's role as a public witness to Marconi's private experiments, history of wireless radio and the nature of Marconi's "shows." It also provides a rare case study of how the credibility of an engineer can be created, consumed, history of wireless radio and suddenly destroyed. The book concludes with a discussion of de Forest's audion history of wireless radio and the shift from wireless telegraphy to radio.

History of radio - The pre- and early history of radio is the history of its technology. Later, the history is dominated by programming and contents, which is closer to general history.

History of electricity and radio - === Early developments in electricity ===

Institute of Radio Engineers - Following several attempts to form a technical organization of wireless practitioners in 1908-1912, the Institute of Radio Engineers (IRE) was finally established in 1912 in New York. Among its founding organizations were the Society of Wireless Telegraph Engineers (SWTE) and the Wireless Institute (TWI).

Wireless local loop - Wireless local loop (WLL), also called radio in the loop (RITL) or fixed-radio access (FRA) or fixed-wireless access (FWA), is the use of a wireless communications link as the "last mile" connection for delivering plain old telephone service (POTS) to telecommunications customers.

In 1895, Guglielmo Marconi sent a telegraph message without wires, but he didn't send voice over the airwaves; Reginald Fessenden, in 1900, accomplished that. The apparatus that he used contained all the elements that were incorporated into radio systems before the development of the vacuum tube.
