The world s first mobile phone is what the world s first mobile phone was

The world's first mobile phone was invented by Martin Cooper, a technician at Motorola.

In April 1973, Martin Cooper, a technician at the famous American Motorola company, invented the world's first mobile phone that could be used by civilians.

When the first mobile phone was invented, Martin Coopa used it to make calls, and in fact, the first generation of analog phones used different frequencies to distinguish between different phones and different users.

The invention of the world's first mobile phone!!

One day in April 1973, a man stood on the street of New York, pulled out a wireless ** about the size of two bricks, and called it, attracting passers-by to stop and look sideways. That man was Martin Cooper, the inventor of the mobile phone. At that time, Coopa was an engineer and technician of the famous American company Motorola.

The world's first mobile communication was played to a rival at Bell Labs, Martin Cooper, 74, who founded his own communications technology research company in Silicon Valley after 29 years at Motorola. Currently, he is the Chairman and CEO of this company. Martin Cooper's idea at the time was to let ** know that wireless communication – especially small mobile phones – is very valuable.

In addition, he hopes to pique the interest of the Federal Communications Commission in supporting Motorola in its rivalry with AT&T, which is also a major communications company in the United States.

In fact, going back further, we will find that the concept of mobile phones appeared as early as the 40s. At that time, it was Bell Labs, the largest telecommunications company in the United States, that began trial production. In 1946, Bell Labs created the first so-called mobile communication**.

However, because of its size, researchers had to put it on a shelf in the lab, and slowly people forgot about it.

It wasn't until the late '60s that AT&T and Motorola became interested in the technology. At the time, AT&T was renting out a very large mobile wireless ** that customers could attach to large trucks. AT&T's vision is that in the future it will be able to develop a mobile ** with a power of 10 watts and use the radios on the trucks to communicate with it.

According to Coopa, this kind of ** is too big and heavy to move and let people take it with him. As a result, Motorola applied to the Federal Communications Commission of the United States, requesting that the power of mobile communication equipment should only be one watt, and the maximum power should not exceed three watts. In fact, the radio power of most mobile phones today is only 500 milliwatts at most.

From the registration of the mobile phone patent in 1973 to 1985, the first modern sense and truly mobile ** was born. It is a box where the power supply and antenna are placed in a box and weighs up to 3 kg, which is very heavy and inconvenient, and the user has to carry it on his back like a backpack, so it is called "shoulder carry**".

The world's first mobile phone, Motorola Dynatac

Weighing in at 8000x 2 pounds, with half an hour of talk time and $3,995 in sales**, it's truly the most expensive brick to tell.

46 years ago, the world's first mobile phone was born, and the inventor used it to make a **.

The world's first mobile phone was the Motorola Dynatac 8000X.

The Motorola Dynatac 8000X is a mobile phone produced by Motorola, designed by Rudykrolopp after ten years of research and development, and launched in 1983.

The Motorola Dynatac 8000x weighed 2 pounds, had a half-hour talk time, and was on sale** for $3,995 at the time. Designed by rudykrolopp.
