Wireless communication

Almost exactly a century ago , on Dec. 12 1901, Italian inventor Guglielmo Marconi sat in New foundland , Canada, listening through an earphone for signals that few believed he would ever recieve.But arrive they did, just after noon, from the far side of the Atlantic in Cornwall, England . The faint pip-pip-pip was mearly the letters broadcast in Morse code, but in it, Marconi heard the future . "I now felt for the first time absolutely certain that the day would come when mankind would be able to send messages without wires, " he wrote," Not only across the Atlantic but between the farthermost ends of the Earth " .
