How it started... -1860s, a Scottish physicist by the name of James Clerk Maxwell predicted how radio waves could exist. -1866, Mahloon Loomis was able to make a kite connected to a meter make another one move which was the first proof that wireless comunication was possible.
-1878, David E. Hughes used a clockwork transmitter to send morse code. -1886 Heinrich Rudolph Hertz showed that rapid changes in electric current could be projected into space similar to light and heat. -1888 Hertz used a sparkgap transmitter to create and measure the Ultra High Frequency range. -1891 Nikola Tesla began his research into wireless technology, he was able to reliably create radio waves and different frequencies, successfully have demonstrations of radio, and send long-distance signals. He also managed to obtain a U.S. patent for the invention of the radio. -1899 U.S. Army communicated via radio with a lightship off of Fire Island, New York. -1901 Radio telegraph service implemented across 5 Hawaiin Islands. -1903 Messages were carried between President Theodore Roosevelt and King Edward VII. -1905 Naval battle of Port Arthur (Russo-Japanese War) had results transmitted via radio. -1906 Weather Bureau begins to experiment with radio transmissions in an attempt to pass on weather information faster. -1910 Regular radio-telegraph service opened across the Atlantic Ocean. -1912 First radio-telegraph across the Pacific allowed communication between San Francisco and Hawaii. -Reginald Fessenden and Lee de Forest found a way to allow multiple signals to be transmitted simultaneously via the inventory of the Amplitude Modulation (AM) radio. This replaced spark-gap transmitters because they consumed the entire spectrum’s bandwidth. -1933 Edwin H. Armstrong invents the Frequency Modulated (FM) radio which is designed to mitigate static from outside sources such as electrical equipment and the atmosphere. -1947 Bell Labs invents the transistor. -1954 Sony (at the time, a small Japanese company) launches the transistor radio. -1965 First master FM Antenna system is established on the Empire State Building in New York City, designed to allow the multiple simultaneous FM stations to be transmitted from a single source. |
