Mobile Phone: Story of the Current Essential Device

February 16, 2015 7:48 PM

The mobile phone story begins on the 3rd of April 1973, when a senior engineer, Martin Cooper, who was working for the Motorola company, used for the first time a mobile phone to make a phone call with a potential customer.

The mobile phone was 1,100 kg heavy and its dimensions were 228,6 mm x 127 mm x 44,4 mm. Quite big if we compare it with the actual phone sizes ! This prototype needed 10 hours for a full charge and allowed a call for about 30 minutes.

In 1983, the first mobile phone arrived on the market. It was called “Motorola DynaTAC 800x” and its price was around 2500 £. Not really cheap ! Because of the very high price, the mobile phone was just for rich and professional people.

Let’s now see its features:

The Motorola DynaTAC, like we said before, had a battery that needed 10 hours for a full charge and offered 30 minutes of talk time life. It could also register 30 phone numbers in his contact list.
It had a LED Display and an input keyboard with 12 keys plus a key to dial and end a phone call and another one for the volume control.

Therefore in 1973, Cooper demonstrated to the world that this device was not a simple Walkie-Talkie. He took inspiration from the Communicator used by Star Trek (maybe that’s why years later, they produced a mobile phone series named StarTac).

So who was responsible for this great invention ? Most of people thought that the first mobile phone producer was Nokia, but as we can understand with this little story, that it is not true.
