The cell phone

The telephone was invented in1875 by Alexander Graham Bell.
The wireless communication was born with the radio, invented by Nikolai Tesla in 1880 and it was formally introduced in 1894 by a young Italian called Ggulielmo Marconi.
It was expected that one day, both technologies would be combined in a same device.

The cell phone is very useful when trying to communicate with other people in a place where there is no normal telephone; there is no need to be connected to any base.
Nowadays there are few people who don’t own one, and this is because it is a very practical device.
