Radiotelegraphy
Benefits
Compared with traditional telegraph, which multiple telegraph offices with enormous labor power to support the transmission and costly installation and maintenance of telegraph lines, its usage were limited to sending urgent message within specific region only. Wireless telegraph reduced the marginal cost greatly and allowed user to send more accurate messages to rural areas.
Marconi, an Italian inventor, transmitted Morse code signals using radio waves wirelessly to a distance of 3.2 KMs in 1895. It was the first wireless transmission in the history of science. Since then, engineers and scientists were working on an efficient way to communicate using RF waves. Wireless technology has been continuously evolving to meet increasing demands and higher specification requirements along with development of 1G to 4G communication system. Telephone became popular during the mid of 19th century. Due to wired connection and restricted mobility, engineers started developing a device which doesn’t requires wired connection and transmit voice using radio waves.
It had been heavily employed by the Royal Navy to communicate the position of enemy artillery which successfully helped spotting enemy submarines and aircraft defending during world war.
By the time of Titanic’s maiden voyage, radiotelegraph had become an essential thing in most passenger ships operating in the north Atlantic which gave the operator the chance to catch the SOS signal and immediately sent out rescue team two hours before Titanic sunk. It is believed that no one could survive if there was no any wireless telegraphy.
Negative Impact
The United States used the radio for propaganda in Afghanistan against Soviet Union during the war between capitalism and communism. The use of radio in Pakistan also has a great importance due to its locality and easy access to maximum population of the country. In Pakistan during militancy especially throughout late 2006 to early 2010 in Malakand regions radio has been used for different purposes by different groups to attract the people of the area toward their ideas and missions. It should be mentioned that either radio with legal or illegal status, has an impact on the audience which may develop a society or may destroy the good social values of the society.
Invention History
Guglielmo Marconi, (1874-1937) was Italian physicist and inventor of a successful wireless telegraph, or radio (1896). In 1909 he received the Nobel Prize for Physics, which he shared with German physicist Ferdinand Braun. He later worked on the development of shortwave wireless communication, which constitutes the basis of nearly all modern long-distance radio.
