  3. Key Events in Cellphone History • 1830 Joseph Henry transmitted the first practical electrical signal • 1837 Samuel F.B. Morse developed his fully functional telegraph • 1842 Joseph Henry discovered that an electrical spark between two conductors is able to induce magnetism in needles, this effect is detected at a distance of 30 meters • March 1876 Alexander Graham Bell made his first successful telephone experiment. Bell filed for a patent February 14, 1876 beating Elisha Gray by only two hours. • 1879 David E. Hughes discovered radio waves. He possibly did make the first mobile telephone call. • 1910 Magnus Ericsson and his wife Hilda used the first "car telephone" hooking two long sticks over a pair of telephone wires and connect to an operator in the telephone exchange. • Early 1920s First police car radios and walkie-talkies in metropolitan New York area. • 1979 The first commercial mobile phone network was opened for business in Tokyo.
