A '''radio''' is a device that either transmits or receives signals sent using low-frequency electromagnetic waves. Radio is widely used in modern communications.  The first person to experimant with radio waves was  Heinrich Rudolf Hertz in 1886.  One of the major pioneers of Radio technology was Nikola Tesla.  Tesla's theories and experiments lead to the demonstration of the first remote controlled vehicle and practical transmission equipment.  The first Trans-Atlantic radio transmission was made by Guglielmo Marconi.  As a fledgling technology the use of wireless transmissions did not have a standardized protocols until the sinking of the Titanic lead to the creation of a 24 hour emergency radio watch.

Radio as a communication device was quickly to come into it's own during the [[Great War]] but did not come into major general use until small portable communication systems were developed.  With the use of radio for the transmission of important military information also lead to creation of code books and electronic encoding devices.  Two examples of these are the American Navaho Code Talkers and the German Enigma Machine.  Because of how important knowing enemy information is and attempting to keep it secret lead to massive code braking and code creation efforts.  The best known of these would be the Allied breaking of the 'perfect' Enigma machine as part of ULTRA by mathematicians and linguists at Bletchley Park.  This also lead to the creation of what may be the first electronic computer the Colossus or Turing Bombe that was used to streamline the decoding process.
