Dr.Martin Cooper invented the mobile phone and made the world’s first mobile phone call on April 3rd, 1973. However there is a controversy over who invented the mobile phones and cellular systems. Archives also suggest that American Telephone & Telegraph discussed developing a wireless phone in 1915. Yet they were afraid of using this technology as it could have eaten up into its customer base of landline telephones. The first cellular telephone system was made operational in Tokyo in 1979. In the United States, the first system became operational in 1983 in Chicago.Mobile phones proliferated and got combined with various other devices like clocks, calculators and so on. It was the ability to transfer data which permitted the marriage of the cell phone with the internet. The day is not very far when almost all communications in the world will become wireless.
