The beginning
Heinrich Hertz proved you could transmit and receive electric waves wirelessly. -
Advancing radio communication
Guglielmo Marconi - widely considered the “father” and “inventor” of radio
Pioneered a lot of the general basis of how long-distance radio transmissions work
One of his original inventions was an alarm that would go off when it detected electric waves from lightning
Marconi had a huge breakthrough in 1885 when he discovered he could sent the signal a greater range by raising the height of the antenna
Filed for patent on his first radio apparatus in 1886 -
first wireless communication
Marconi send the first wireless communication over open sea in 1887. It went over the Bristol Channel in Wales at a distance of 6km (about 4 miles) -
Developing wireless telegraphs
Nikola Tesla - inventor - develops the Tesla Coil - induction coil widely used in radio
Produce high voltage, low-current, high frequency alternating-current electricity -
First transatlantic message
First transatlantic message FROM the US was in 1903, when a Marconi build station sent a message from Massachusetts to the UK -
The AUDION tube
invented in 1906 - it is essentially the very first amplifier to help push waves further and further by providing power to the signal
