In November 1894, Indian physicist, Jagadish Chandra Bose, shown to the public use of radio waves in Calcutta, but he was not interested in patenting his work. Bose trigger gunpowder and rang the bell at a distance using electromagnetic waves, proving that communication signals can be sent without using wires. He sends and receives radio waves distance but take advantage of this commercial success.
1895 public demonstration by Bose in Calcutta before Marconi's experiments with the wireless signal to Salisbury Plain in England in May 1897. Bose shown the ability of electric light to travel from halls of lectures, and by the chamber and the intervention, the third space 75 feet (23 m) away from the radiator, so the past three solid walls on the road, as well as agency chairman (who happen to be Lieutenant-Governor). Recipient distance still has enough energy to make contact to set the bell ringing, pistol discharged, and a miniature mine exploded. To get this result from the small radiator, Bose set up an apparatus which strangely anticipates 'antennas' high-modern wireless telegraphy circular metal plate on top of the beam, 20 feet (6.1 m) high, which is inserted in connection with a similar radiator and the receiver apparatus.
Form 'coherer' which was designed by Professor Bose, and described by him at the end of his paper "On Electrical Polariscope new 'cognition and allowed to reach up to leave a little time desired . In 1896, the British Daily Chronicle reported UHF experiments: "The inventor (JC Bose) has transmitted signals at a distance of nearly a mile and here resides the first application and clear and important new theoretical surprise."
After the Friday evening lecture at the Royal Institution Bose, Electrical Engineer surprisingly stated 'no secret at all times made for construction, so it has been open around the world use for practical purposes and possibly make money. "Bose sometimes, and awful, criticized as there is no way to make no profit from his invention.
In 1899, Bose announced the creation of a "coherer irons Quicksilver phone detectors" in a paper presented to the Royal Society, London. Then he received U.S. Patent 755,840, "Detector for electrical disturbances" (1904), for a specific electromagnetic receiver. Bose continues to research and develop other contributuions for the development of radio.
