  • A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the s, and in medical equipment such as.

    Wardenclyffe Tower (–), also known as the Tesla Tower, was an early experimental . At this point Marconi was transmitting radio signals beyond the range most physicists thought possible (over the horizon) and the description of the.

    Who improved the early spark-gap transmitter design allowing much higher spark-gap transmitters allowing significantly higher levels of radio-frequency.

    He also made the " Oscillion ", an undamped wave transmitter. The receivers were simple unamplified magnetic detectors or electrolytic detectors. In this sense it could be considered that there exist some differences between the terms "the invention of radio" and "the discovery of radio phenomena". If a major mistake regarding Tesla's priority to inventing Radio is made in , and if this mistake is not officially righted until , then reference books and textbooks had thirty years to mistakenly elevate Marconi as the inventor of radio. However, this made transmission impossible in rainy or even damp conditions.

    The invention of the communication medium commonly known as radio , although generally attributed to Guglielmo Marconi in the s, spanned many decades, from theoretical underpinnings, through proof of the phenomenon's existence, development of technical means, to its final use in signalling. The idea that the wires needed for electrical telegraphy could be eliminated, creating a wireless telegraph , had been around for a while before radio based communication.

    Inventors attempted to build systems based on electric conduction , electromagnetic induction , or on their own theoretical ideas. The discovery of electromagnetic waves , including radio waves , by Heinrich Rudolf Hertz in the s came about after over a half century theoretical development on the connection between electricity and magnetism starting in the early s and culminated in a theory of electromagnetism developed by James Clerk Maxwell by , which Hertz finally proved.

    The development of radio waves into a communication medium did not follow immediately afterwards. After their discovery Hertz considered them of little practical value and other experimenters who explored the physical properties of the new phenomenon, such as Oliver Lodge and Jagadish Chandra Bose , while transmitting radio waves some distance, did not seem to see any value in developing a communication system based on them. In their experiments they did develop electronic components and methods to improve the transmission and detection of electromagnetic waves.

    In the mid s, building on techniques physicists were using to study electromagnetic waves, Guglielmo Marconi developed the first apparatus for long distance radio communication. Fessenden became the first person to send audio wireless telephony by means of electromagnetic waves, successfully transmitting over a distance of about 1.

    Before the discovery of electromagnetic waves and the development of radio communication there were many wireless telegraph systems proposed or tried out. These experimenters used the existing theories of the day or novel theories of their own on how wireless signals could be transmitted.

    Patent , for a wireless telegraphy system where he theorized that convection currents in the atmosphere could carry signals like a telegraph wire. Patent , for a "wireless telegraph" in July The patented system claimed to utilize atmospheric electricity to eliminate the overhead wire used by the existing telegraph systems.

    It did not contain diagrams or specific methods and it did not refer to or incorporate any known scientific theory. It was similar to William Henry Ward 's patent.

    In the United States, Thomas Edison , in the mids, patented an electromagnetic induction system he called "grasshopper telegraphy", which allowed telegraphic signals to jump the short distance between a running train and telegraph wires running parallel to the tracks. Inventor Nathan Stubblefield , between and , [9] also worked on an induction transmission system.

    Forms of Wireless telephony is recorded in four patents for the photophone , invented jointly by Alexander Graham Bell and Charles Sumner Tainter in The photophone allowed for the transmission of sound on a beam of light , and on June 3, Bell and Tainter transmitted the world's first wireless telephone message on their newly invented form of light telecommunication. In the early s Nikola Tesla began his research into high frequency electricity. Tesla was aware of Hertz's experiments with electromagnetic waves from on [12] [13] but, like many scientists of that time thought, even if radio waves existed, they would probably only travel in straight lines making them useless for long range transmission.
