-
Showed mathematically that electromagnetic waves could travel through air
-
Prooved Maxwells theory, showing that someone could produce and detect electromagnetic radiation.
-
Used Maxwells mathematic findings to demonstrate the sending and receiving a radio frequency energy, proposed that this could be used for sending and receiving information
-
Built the first wireless transmiter, it was capable of sending signals up to one and a half miles
-
Allowed the production of the first commercially available radio sets, but this where plagued with problems such as electrical interference
-
Developed the Worlds first transatlantic radio communication service between Clifton, Ireland and Newfoundland
-
Were used mostly in American homes, this is the evolution of spark gap radios which had some problems. This were the first widely produced and used radio sets in America. This was a connection of Americans to the rest of the country
-
Inveted FM radio (Frequency Modulation), this uses a wavelength less static than AM (Amplitude Modulation)
-
Advantage, "last evolution", were much cheaper, uses less power, smaller size and very long lifespan
