When was the world s first mobile phone created?

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, the Motorola Dynatac 8000X, weighs 2 pounds, has a half-hour talk time, and sells $3,995**, making it truly the most valuable brick. ）

In the late '60s and early '70s, Bell Labs and Motorola were competitors in mobile phone research and development technology. In order to declare victory to his opponent, Martin Cooper used the most direct method, using the developed mobile phone to call Bell Labs a ** on the street. Although the people at Bell Labs didn't take the call seriously, it meant a lot to future generations.

Because this is the first mobile phone call in the history of human communication, and April 3, 1973 is also recognized as the birthday of mobile phones.

The world's first mobile phone, Motorola Dynatac 8000X, 1985.

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.

1. The first mobile phone in China was opened in 1987, and the model of that mobile phone was Motorola 3200, which was very popular at that time. The mobile phone was owned by a businessman in Guangdong.

The pager entered the era of Wang Ying's popularity, the white screen mobile phone appeared in 93, and the first color screen mobile phone appeared in China in 98.

3. The first model with full Chinese interface, Motorola CD928+, was officially sold in China in 1999.

In October, the Nokia 7650 was China's first slider phone, but most people care about its camera capability.

In May, the Nokia Chameleon 6110 was the first phone to have built-in games. In the same year, the iPhone was released, which kicked off the smartphone.
