GSM History In 1876telephone was introduced to the public in Philadelphia

USA, ALEXANDER GRAHAM BELL was able to transmitspeech electrically in one direction only on COPPER WIRE. Thiswas later perfected for two way communication.

In the end of 19th CENTURY a German Scientist namedHEINRICH RUDOLPH HERTZ discovered that from anelectric spark there seemed to emanate invisible waves of forcewhich could be captured at a distant location by a suitablyconstructed receiving device.

In 1897 GUGLIELMO MARCONI made first wirelesstransmission over 15KM in Bristol and in 1901 he transmitted these

waves overseas and began to call it RADIO.
