A Brief History of Radio

Radio is a technology that transmits data to a remote location where a receiver detects the simple without the use of wire. Radio stations are believed to AM or FM in terms of a common glossary. In fact, radio waves are also used to receive and send data as the waves of satellite broadcasts, Bluetooth devices and WiFi networks.


The radio history dates back to mid-1800. This was the theory related to electricity and magnetism. Telegraph was the first available technology developed from this discovery, although it requires wire ropes.

James Maxwell had developed their own theories regarding electromagnetism in 1865. This was indeed the first experiments of wireless technology. Many physicists such as Thomas Edison, Henry Loomis Mahlon and William Ward, patented methods for sending and receiving wireless telegraph system, but a working system was never demonstrated for them.

In 1884, Calzecchi-Onesti Temistocle invented a device that was subsequently refined. Edouard Branly coherer later called it in 1886. It was a glass tube filled with metal filings connected to the electric current produces an audible click of a probe to receive the signal. The coherer became the first technology that allows radio signals to be received.

In 1887, Heinrich Hertz was the first he had refined a system that enabled him to experiment with sending wireless signals to a wireless receiver. He was also honored in 1933. In 1892, a Serbo-Croatian immigrant in the USA, Nikola Tesla demonstrated the first full radio transmitter and receiver system and became the first person to invent radio hit. Unfortunately, there was a fire in his laboratory in 1895 and failed to prove his radio. However, in 1898, Tesla demonstrated the first radio and later filed patents for radio in 1900.

An Italian, Guglielmo Marconi was fascinated by the idea of ??transmitting a wireless signal of the telegraph. In 1894, successfully invented a spark transmitter with an antenna. Unfortunately, the Italian Postal Service, which controls the wire services were not interested in your experiment. He moved to England in 1896 where it successfully demonstrated its technology for the English Post Office who immediately recognized his services. Queen Victoria was also impressed by his invention. Marconi was related to the British nobility who were powerful investors in their companies and emerging markets in the U.S..

In 1900, Reginald Fessenden other Americans demonstrated their new technology that was used by the department for sending time information to ships at sea. He invented the detector Barrettes allowing you to develop the amplitude modulation (AM).

The year 1920 was the real birth of modern radio and almost every house had a radio. Television began to catch up during the decade of 1960 and was the preferred means of entertainment for Americans. However, the radio securely in the car and by the 1990s, many Americans listened to the radio in your car or at work. Wireless broadcasting traffic reports, music and news radio receivers still prevails despite the advent of the Internet and satellite radio.
