Today there is a huge selection of mobile phones for every taste and client's wallet. For half a century, a compact portable communication device has become indispensable for most of the world's inhabitants.
The history of the emergence of a mobile phone
Back in the middle of the XX century. the option of making calls using a portable means of communication was proposed. In 1963, the Soviet engineer L. Kupriyanovich developed the first experimental model of a cell phone. However, this model weighed about 3 kg and came with a special portable base. This option required a thorough revision.
The idea of using a communication device in a car came from the Bell Laboratories. And at the same time, Motorola specialists were also considering the option of a compact portable communication device. At that time, this company was already successfully producing portable radios.
The man who created the first portable mobile phone
It is worth noting that the first inventor of the mobile phone was Martin Cooper, who was the head of the communications department at Motorola. At first, the entire entourage of this talented inventor was skeptical about this option for a means of communication.
In April 1973, Martin Cooper called the head of Bell Laboratories using his invention from the streets of Manhattan. This was the first call in the history of a mobile phone. It should be noted that the choice of the subscriber for Cooper was not accidental. At that time, both companies were trying to be the first to create a communication device. Cooper and his team were the first.
Only in 1983, through lengthy developments, was an exemplary version of a modern phone presented to the public. This model was called the DynaTAC 8000X and was priced at almost $ 4,000. Nevertheless, there were a huge number of people who wanted to buy a new device, they even signed up for the purchase of the device.
What the very first mobile phone looked like
It is worth considering the appearance of the first portable communication device, which was significantly different from today's devices:
- the length of the tube was about 10 cm, a fairly long antenna protruded from it;
- instead of the now familiar display on the phone, there were large buttons for dialing a subscriber's number;
- the weight of the first cell phone was approximately 1 kg, dimensions: 22, 5x12, 5x3, 75 cm;
- the phone was intended only for making calls;
- in talk mode the battery worked for 45 minutes - 1 hour, and in quiet mode - up to 4-6 hours;
- it took about 7-9 hours to charge the first mobile phone.
