History will always be covered in dust, but some things that most people recognize can be considered correct. Today, the world's first mobile phone in the true sense is generally believed to be invented by Motorola in the United States in 1973.
The powerful communication powerhouse - the United States.
At the beginning of the last century, 60 years after the end of the Civil War in the United States, the industrial revolution was introduced to the United States, allowing the United States to develop rapidly in machinery, electrical and other aspects, and the research and development of electronic communications officially entered the fast lane.
In 1902, in Kentucky, USA, an electrical enthusiast named "Nathan Stabfield" tinkered with the first wireless telephone device in his residence. Through a 120-foot-high antenna, he successfully sent the voice to another machine in the form of a magnetic field. Later, after many transformations, it was successfully installed on a car. It can be regarded as the first human exploration of a "mobile" telephone. Later he applied for a patent, but he never realized his wish to sell it until his death.

1938, on the eve of the outbreak of the Second World War, Bell Labs was invited to invent the world's first handheld "mobile phone" for the US military, and it was not mass-produced due to factors such as short communication distance. Today, it sounds like a walkie-talkie.

During World War II , a long-distance wireless phone that can be moved and comes with its own power supply was finally equipped with the army in small batches, but it is big and very heavy, and it must be carried on it to move.

The first mobile phone in the true sense was born. In the past thirty years after
, due to the lack of market demand, mobile communication technology has not attracted attention, and Bell Labs has also kept this technology aside. But there is a technician named Martin Kupa who believes that this mobile phone technology can change the world in time, so he has been silently doing his own research and has repeatedly attracted the sneer of Engel's in his lab.

On April 1973, Martin Kupa, who had switched to Motorola, finally invented the first civilian mobile phone. On that day, Martin Kupa also used it to dial the world's first mobile phone call in Manhattan . The recipient was Engel, a competitor in Bell Labs, who was already in AT&Th ( AT&T) at this time. Engel, who answered the phone, was silent for a long time after hearing this before congratulating the other party.
or above marks the birth of the world's first real mobile phone (civilian).
21st century will be the stage for the Chinese.
In the next half century, the United States has made more firsts in the field of communications. The world's first mass-produced mobile phone is the Dyda TAC 8000X of Motorola, the world's first mobile phone with PDA business functions, manufactured in cooperation with IBM and BellSouth. The one that is recognized to open the door to modern smartphones is Apple's iPhone 2G.

Today, with the efforts of my country's technical talents represented by Huawei , ZTE , China Mobile, and Science and Technology Institute, they have achieved a three-point share of the world in the 4G era and gained the advantage of most patents in the 5G era. Looking forward to the future 6G era, my country's communication technology will lead the world stage.
