Кто изобрел первый в мире мобильный телефон Who invented the world's first mobile phone

Описание: Who invented the phone.

With the appearance of the first telegraph in 1837, which gave the world the opportunity to transmit information at a distance, people's lives radically changed. But the appearance of the first telephone set, with the help of which the distant sound transmission was realized, became a real sensation.
Today, no one can even imagine themselves without a personal mobile phone. Technologies do not stand still, the market of telephone sets is constantly expanding and presents to consumers annually new, improved models. But let's remember how it all began, who invented the first telephone set, how mobile phones appeared and what the success of modern Apple models is.

Create the first phone.

The first telephone set was introduced in 1876 in the United States of America, and Alexander Graham Bell became the creator who patented his invention. Initially, Bell's phone worked 200 meters away, but the scientist did not stop working and improving his invention, and a year later the phone went through such an upgrade that it remained unchanged after another 100 years. The phone itself was not planned to be created by Bell. The goal of the scientist was to improve the telegraph - he was trying to achieve the transmission of 5 telegrams simultaneously. In the process, records were created with different frequencies, one of which once failed. Partner Bella, angry, began to swear. And Bell, who is at this time at the receiving apparatus, unexpectedly heard himself remotely the voice of his partner. From that moment on, the story of the creation of the first telephone set began. Bell received a telephone patent that is considered one of the most profitable in the United States and in the world. He brought wealth and worldwide recognition to the creator, and the name of Alexander Bell has gone down in history forever.

The first mobile phone.

The idea of ??creating mobile phones appeared in the middle of the XX century, and again in the United States of America.

In 1947, the Bell Laboratories laboratory proposed to create a mobile phone. True, by this they meant an apparatus that would be mounted in a car, since the weight of the phone was 30-40 kg without a power source. Only in the 70s, the weight of the phones was reduced to 14 kg, but the power supply was still located in the car. Until 1972, Motorola had no relation to mobile phones, the main goal of the company was to create portable radio stations. Everything has changed thanks to a simple employee of the company, Martin Cooper, who at one random moment came to the conclusion that creating an oversized cell phone is real. Having shared this discovery with his colleagues, he began to develop, which continued throughout the year. In 1973, the Dyna-Tac was ready. It was a small-sized cell phone by the standards, weighing 1.15 kg and measuring 22.5-12.5-3.75 cm. It housed 10 numeric keys, a call button and a "hang-up" button. The display on the phone was missing. The battery held for 35 minutes of continuous conversation, but after charging the phone had 10 hours.

To implement the invention it was necessary only to test it in practice. It happened on April 3, 1973 in New York. On the roof of the 50-story building, they assembled the first “training” station and Martin Cooper personally conducted an experiment, dialing the head of Bell Laboratories and talking to him on his mobile phone. It was a triumph that became the first step in the speed development and improvement of “hand-held” mobile phones.

The appearance of touch phones.

This may seem surprising, but the first touchscreen phone was not widely used by users, and the creator company even refused to continue working in the field of mobile devices.

This happened in 1993. IBM, specializing in the production of computer technology, introduced the world first touch mobile phone, calling it "IBM Simon". At that time, it was a maximum of possible characteristics, weighed 0.5 kg, and most of the operations on the display were really done with fingers. The phone battery was designed for 1 hour of continuous talk or 8 hours of standby time. Its operational memory was 1 megabyte, and the developers also provided for receiving e-mail and faxes to the telephone.

However, as we have already noted, IBM Simon did not receive distribution. Firstly, this was due to the overpriced price of the phone - $ 1,100. Secondly, the device was unreliable and often needed expensive repairs. As a result, the development company simply self-destructed from the mobile phone production market.
