How did Nikola Tesla invent the radio?

Answer 1

With his newly created Tesla coils, the inventor soon discovered that he could transmit and receive powerful radio signals when they were tuned to resonate at the same frequency. When a coil is tuned to a signal of a particular frequency, it literally magnifies the incoming electrical energy through resonant action. By early 1895, Tesla was ready to transmit a signal 50 miles to West Point, New York.

Answer 2

People in several countries were experimenting with the idea of radio transmission. Hertz in Germany annd Marconi in England were among the most prominent.

Where the Radio was InventedThe first radio transmission took place in Italy and was credited to Guglielmo Marconi, an Italian inventor. However, numerous discoveries by other people, such as Armstrong, Hertz, and Tesla lead up to the actual invention of radio.

Guglielmo Marconi invented the first functioning transmitting/receiving radio in about 1895, somewhere in Britain. The first factory producing radios was in Chelmsford, UK in 1898, by Marconi's The Wireless Telegraph & Signal Company.

Interesting Footnote to history: In 1943, the U.S. Supreme Court overturned Marconi's patent in favor of Tesla's, so technically speaking Tesla was the inventor of radio.
The radio patent history had an argument as who made it first. Marconi was given a patent on the radio but latter on, it was found that Marconi used some patents of inventions by Tesla. That Tesla also demostrated radio basics in lectures and the patent was given to it's rightfull owner.

Based on that, the radio was invented in New York, United States of America.
