We use mobile phones for various purposes like talking, sending mail or for other reasons. Have you ever wondered how this mobile phone was invented? Today we will know the history of the invention of this mobile phone.
The first mobile phone was created in 1973, in New York City, USA - by engineer Martin Cooper. He is called the father of mobile phone
Martin Cooper worked at Motorola, a small telecom company at the time. But he had a dream: a day would come when everyone would have their own phone, and on that phone they could be contacted at any time.
At that time, the telephone was something that was wired to people's office desks and homes. That's why the concept of mobile phone was like science fiction to common people. The idea of a mobile phone came to Martin Cooper's mind for the first time when he saw that the characters of an American comic called Dick Tracy communicated with each other with the help of a kind of video wristwatch. That's exactly what a team of 20-30 people led by Martin Cooper built in just 30 days.
48 years ago today in April 1973, the first mobile phone model was introduced at the Hilton Hotel in New York. The first mobile phone was 10 inches long by 2 inches wide and about 4 inches thick. The weight of that mobile phone was more than one kg. Talking for just 20 minutes would drain the phone's battery. So many people laughed at that phone. But really building such a phone at that time was an impossible challenge.
Martin Cooper also made the first call with a mobile phone in the history of the world. He made the call to a friend of his, an engineer working at AT&T, while walking on New York's 6th Avenue.
Mobile phones were invented based on a technology called cellular technology invented by AT&T. AT&T didn't even think about carrying the phone in hand. They developed this technology primarily to connect telephones to cars. But the tiny company Motorola went beyond the imagination of AT&T, the world's largest telecom company at the time. First of all, the first mobile phone on the market Motorola company! But it took another ten years for the first mobile phone to hit the market. In 1983, the Motorola DynaTAC (DynaTAC) model phone came to the market for the first time.
The price of that mobile was 4 thousand dollars, the current market value of which is more than 3 lakh rupees. Besides, the call rate was very high then. In those days, mobiles were mostly used as a toy for adults. Many people think this mobile looks like a brick, while others think it looks like a shoe. So many called it The Brick. Others said shoe phone. However, Martin Cooper named it Dynamic Adaptive Total Area Coverage; In short (Dynatack). That mobile phone will become so important in people's lives, maybe no one realized!
Today's mobile phone with radio, TV, music player, camera, Internet and what not! Today more than 87 percent of the total population of the world is covered by mobile phone communication and more than 5.11 billion people are using mobile phones regularly.
Starting with Motorola, only 10 companies have occupied 76 percent of the current world smartphone market. As we can easily communicate from one end of the world to the other through mobile phones; It is becoming possible to maintain communication from Earth to the outer solar system using the Deep Space Network developed by the American space research organization NASA.
It was with that technology that NASA launched the Voyager mission in 1977. Voyager 1 is the farthest human-made object from Earth so far. Voyager is still active 44 years after launch.
In the 21st century, mobile phones have radically changed our way of life. Now we don't have a moment without a mobile phone! Some more amazing technologies are added to smartphones in the future; Looking forward to seeing it.
