The inventor of the first mobile phone


Martin Lawrence Cooper (December 26, 1928), a famous inventor born in Chicago, Illinois, USA, was the father of a mobile phone because he pioneered the development of mobile phones. In 1950, he obtained a master’s degree from the Illinois Institute of Technology.

At the time, Cooper was an engineering technician at the famous Motorola company in the United States.

 After working for 29 years in Motorola, he founded his own communications technology research company in Silicon Valley.

The inventor of the first mobile phone

 Martin Cooper was the inventor of the mobile phone and opened the world’s first mobile phone in 1973. He said, “Every generation of product updates, they are trying to introduce some interesting things.

 Cooper believes that smartphones are important at present, but there are not many “necessary” applications on smartphones.

 Most applications are for users. Providing “convenience”, without it users continue to survive. The “necessary” application means that without it, users will not be able to live normally or even die.

The first mobile phone is more

On April 3, 1973, bursts of applause broke out in the Motorola lab in Manhattan, New York. “We have succeeded!” Martin Kupa, the leader of the research team, held their research – the world’s first mobile phone. Its birth means the beginning of a new era – the birth of wireless communications.

Questioning smartphones more

At the end of 2008, Cooper mentioned in his public speech that he had given it to his grandson after using the iPhone for a few weeks. Because he can’t “get” the iPhone’s contact list.

 In addition, the iPhone’s shape design and service provided the “father of the mobile phone” is very dissatisfied, he thinks these seem to be substandard.

Life storyedit

First mobile phone

On April 3, 1973, a burst of applause broke out in the Motorola lab in Manhattan, New York . “We have succeeded!” The researchers in the lab cheered. The research team’s leader, Martin Cooper, said with the results of their research, the world’s first mobile phone, excitedly said: “My dear friends, I am going to the streets, using this The phone calls a person, who do you guess?” “Your family?” “Your

friend? “The people present have speculated. “No, you all guessed wrong. Cooper smiled mysteriously. Then he walked out of the lab and went to the streets of Manhattan .

 The people who passed by him all stopped and stared at the phone with no lines in his hand and stopped to watch. Before, people never saw a phone without a rope. Under the gaze of everyone, Cooper pressed a bunch of phone numbers.

The phone passed, and there was a man’s voice: “This is Yule Engel ( JoelEngel). Cooper said excitedly in an almost trembling voice: “Yur, I am talking to you on a real mobile phone, a real mobile phone!” “The phone is silent. It is none other than Cooper’s long-time competitor, a scientist at Bell Labs, Jur Engel. Cooper is taking the world’s first mobile phone, Dyna.” TAC.

Compared with today’s mobile phones, this phone is cumbersome and cumbersome—the number of internal boards is 30, the talk time is only 35 minutes, and the charging time is 10 hours.

 There are only two functions of making and receiving calls. At the time, the birth of this mobile phone meant the beginning of a new era—the birth of wireless communications. [1]

Design inspiration

Martin Cooper said that his invented mobile phone was inspired by the TV series “Star Trek”. “When I saw Captain Cooke playing a radio phone, I immediately realized that this is what I want to invent. thing.”

Martin Cooper was born in Chicago, USA in 1928 and received a master’s degree from the Illinois Institute of Technology in 1950. After graduation, Cooper participated in the US Navy.

After retiring, the 29-year-old Martin Cooper began working in Motorola’s personal communications business, which was 15 years. In 1973, American Telephone and Telegraph Company (AT & T) invented a new concept, called “cellular communication” (cellularcommunications).

The so-called cellular communication is a cellular wireless networking mode, which is connected between the terminal and the network device through a wireless channel , thereby enabling users to communicate with each other during activities.

Martin Cooper feels that this is a very good idea. “But later, AT&T thought that the cellular communication people need is just ‘vehicle communication’. We are very suspicious of this conclusion. We know that people don’t want to talk to cars, houses, offices.

To speak with people. To prove this, we intend to invent a cellular phone to prove to the world that the idea of ​​personal communication is correct. We believe that the phone number should correspond to people rather than places.”

At that time, the TV series “Star Trek” was being played, and the radiotelephone of Captain Cooke became the prototype of Copa and his team inventing the mobile phone. “The task was urgent, and the company asked us to make a mobile phone model within six weeks.”

 At that time, the US Federal Communications Commission was considering whether to allow AT&T to establish a mobile network in the US market and provide wireless services. In addition, AT&T itself developed mobile phones. plan. Motorola is not willing to let good business opportunities slip away.

Three months later, the first mobile phone model was completed. So, there is the scene at the beginning of the article.

Martin Cooper spoke about an interesting story in a mobile phone invention. “The shape of the first mobile phone was actually the result of competition between five industrial design teams, but the simplest one was chosen (its basic design has been popular for almost 15 years).

 The original design is very small, just the electronic system. Engineers have to put in hundreds of parts, and the final phone is five times larger and much heavier than the original design. [1]

Questioning smartphone

The birth of the first mobile phone model made people see the hope of wireless communication.

However, the mobile phone is really on the market, but it is 10 years later.

From 1973 to 1983, Cooper led his team to five technological innovations on the first mobile phone, each time successfully making the phone smaller and lighter. “By 1983, I designed a mobile phone that was only 450 grams.

” Cooper is very proud of it. However, the price of the phone at the time was quite expensive, reaching $4,500.

In 1983, Motorola’s first mobile phone was sold to the market. At this point, Martin Cooper chose to leave Motorola and start his own business.

 Together with two other partners (one of the partners later became his wife), he opened a company that provided software and mobile billing systems for the mobile phone industry in October of that year . Soon, the company achieved success and in 1986 Copa sold the company.

Cooper has been working on mobile phones, but when he found that no matter how light the phone is and not as popular as he expected, he began to think about other reasons. Cooper found that interference, crosstalk, and noise often occur during cell phone calls.

 The quality of mobile phone calls has become an important factor hindering the development of mobile phones. In order to realize his original dream of freeing humans from the landline, Cooper is determined to abandon the development of the mobile phone body and switch to the field of wireless technology.

In 1992, Cooper founded ArrayComm. The company was founded with inspiration from several talented Stanford University experts who developed a new way to use the antenna to send and receive radio signals. “They found me and hoped that I could help them.

I agreed to try it for a month. But in less than a month, I found this to be an important new technology in the future personal communication field. Since then, I started 24 hours a day, Seven days a week.”

The technology developed by ArrayComm is called “smart antenna.” Most of the time, the radio uses a single antenna to send and receive signals, and ArrayComm’s “smart antenna” can use a minimum of 4 and 12 antennas in an array to generate directional beams, making the antenna main wave pair The quasi-user signal reaches the direction to achieve the purpose of fully utilizing the mobile user signal and deleting or suppressing the interference signal.

By 2009, ArrayComm had operations in 17 countries including China and Japan. ArrayComm focuses on this technology for 2G, 2.5G and 3G wireless standards.

 Martin Cooper said: ” Smart antenna technology can build a more robust wireless communication network with better quality of service for 2G, 2.5G and 3G, and save trillions of dollars for network system operators and wireless users. Cost and cost.”

But Martin Cooper is still very dissatisfied with the quality of service in the wireless network in 2013. “We have repeatedly heard such a commitment to let everyone enjoy the affordable and ubiquitous wireless broadband network. But this promise is only A promise.”

For a smartphone like iphone, Martin Cooper, who is famous for innovation, can’t accept it.

Martin Cooper’s point of view has naturally been challenged. “He is too old to accept new things like the iPhone. Look at Motorola today, companies that don’t want to try new things, change or wait. “Death.” An industry insider said. [1]

Reason for invention

In the United States, there is a college student named Cooper who can’t find a job.

He decided to go to George’s company to try. Cooper is a radio enthusiast . He has worshipped George, a veteran of the radio industry since he was a child.

 If George can accept him, he thinks that he can certainly learn a lot and will be able to achieve great results in the radio industry like George. When Cooper knocked on George’s door, George was focusing on wireless phones, which are the phones we use.

Cooper thought for a long time in his heart and carefully spoke out in front of George. He said: “Mr. Mr. George, I really want to be a member of your company. If you can stay with you, be your assistant, it would be better. Of course, I don’t ask for treatment…” Who knows, Before he finished Kuppa, George violently interrupted his words.

George looked at Cooper with disdainful eyes and said, “Which year did you graduate? How long has it been for the radio?” Cooper said frankly: “Mr. George, I am a college graduate this year, and I have never I have worked on the radio, but I like this job…”

George once again violently interrupted Cooper: “Young people, I see you still please go out, I don’t want to see you again, please don’t delay my time.”

Originally sincere and fearful of Cooper, when the mood calmed down, he said without hesitation : “Mr. George, I know what you are busy with now, are you researching wireless mobile phones? Maybe I can help you. Busy!”

Although he was surprised that Cooper could guess what he was studying, George still felt that the young man in front of him was too naive to be able to use it himself, so he firmly decided to go underground. Finally, Cooper said: “Mr. George, one day, you will look at me!” Soon, Cooper got a job at Motorola.

One day in April 1973, a man stood on the streets of New York and pulled out a wireless telephone with about two bricks. He made a pass and attracted passers-by to pay attention. This person is the inventor of the mobile phone Martin Cooper. At the time, Cooper was an engineering technician at the famous Motorola company in the United States.

The world’s first mobile phone was an opponent who was working for him at Bell Labs. The other party was also developing a mobile phone, but it was not successful.

Cooper said: “George, I am talking to you now with a portable wireless phone.” George couldn’t think of it. The young man who was turned away from his own door really developed a wireless mobile phone before him. .

Cooper later recalled: “I called him and said, ‘Joe, I am talking to you now with a portable cellular phone.’ I heard the ‘bite’ at the end of the earpiece – although he has maintained quite the same courtesy.”

By April 2003, the mobile phone had been born for the full 30th anniversary. This technology has now blossomed everywhere, bringing great convenience to our modern life.

Character achievement

Martin Cooper is 74 years old in 2002. After working in Motorola for 29 years, he founded his own communications technology research company in Silicon Valley and is the chairman and CEO of the company.

 Martin Cooper’s idea at the time was to let the media know that wireless communications—especially small mobile phones—are very valuable.

In addition, he hopes to arouse the interest of the US Federal Communications Commission, and Motorola can support the former in the competition with AT&T (AT&T is also a major communications company in the United States).

In fact, going back, we will find that the concept of mobile phones appeared as early as the 1940s. At that time, Bell Labs, the largest communications company in the United States, began trial production. In 1946, Bell Labs created the first so-called mobile communication phone.

However, due to the size, the researchers can only put it on the shelf of the laboratory, and people will soon forget it.

It was not until the late 1960s that AT&T and Motorola began to be interested in this technology. At the time, AT&T rented a large mobile radiotelephone that customers could place on a large truck.

AT&T’s vision is that in the future, a mobile phone with a power of 10 watts will be used to communicate with the radio on the truck. Cooper believes that the phone is too big and too heavy to be moved.

 As a result, Motorola filed an application with the US Federal Communications Commission to require that the power of mobile communication equipment should be one watt and no more than three watts. In fact, the radio power of most mobile phones today is only 500 mW.

From the 1973 mobile phone registration patent until 1985, the first modern, truly mobile phone was born. It puts the power supply and antenna in a box and weighs 3 kilograms. It is very heavy and inconvenient.

 The user has to walk with it like a backpack, so it is called a “shoulder phone.”

Compared to the “shoulder phone”, the mobile phone that was born in 1973 is much lighter and easier to carry. Despite this, it still weighs about 750 grams, which is still like a big brick compared to a phone weighing only 60 grams.

Since then, the development of mobile phones has become more and more rapid. In 1991, the weight of the mobile phone was about 250 grams; in the autumn of 1996, a mobile phone with a volume of 100 cubic centimeters and a weight of 100 grams appeared.

Since then, it has been further miniaturized and lightened, and by 1999 it was as light as 60 grams. In other words, a mobile phone is no more important than an egg.

In addition to the smaller size and size, modern mobile phones have become more and more like a multi-functional Swiss army knife.

In addition to the most basic calling features, the new mobile phone can also be used to send and receive emails and short messages, and can access the Internet, play games, take photos, and even watch movies! This was unexpected for the original mobile phone inventor.

Mobile phones have become an indispensable communication tool in people’s daily lives, and Martin Cooper’s name is also well known. When a reporter interviewed Martin Cooper, he asked:

“If you were taken over by George, you will definitely help George complete the development of the mobile phone, and this credit will definitely be George’s, isn’t it?” Martin Coupa replied: “No, if George took me in at the time, I became George’s assistant.

We may never be able to develop the current mobile phone. It is because he refused me. I broke the thought of letting me want to learn from him, so I Only then opened up a road to develop mobile phones, and it was successful.

The name of that road is called humiliation. I turned George’s insult to me into a driving force for progress. Without this kind of motivation, it’s not necessarily that I join forces with George.

Yes, in the course of our life, almost everyone will bear humiliation. Some people understand that once humiliation is turned into hope, it is the driving force for success, while others do not understand this truth.

In the end, the burden of humiliation is passively silenced, and my life becomes nothing. Martin Cooper chose the former, so he succeeded.

In terms of communication technology, modern mobile phones have also made significant progress. When Cooper hits the world’s first mobile phone, he can use any electromagnetic frequency band.

 In fact, the first generation of analog mobile phones relied on the difference in frequency to distinguish different mobile phones of different users.

 The second generation of mobile phones – the GSM system is based on extremely small time difference to distinguish users. Today, frequency resources are obviously insufficient, and mobile phone users are also experiencing rapid growth in geometric progression.

 Therefore, the updated CDMA technology that distinguishes different machines by different coding has emerged. Mobile phones that use this technology not only have better call quality and confidentiality, but also reduce radiation, which can be called a “green phone.”


B=The Bund Pictorial C= Martin Coopear

Change your phone six months

B: Where is the first mobile phone?

C: Actually, the first phone used for display has two samples.

After the internal parts of one of the mobile phones were sealed in a glass box, they were kept by me as the representative of the working team that invented the mobile phone; the other mobile phone was collected by Don Linder, who led the team to make the electronic system . .

B: What mobile phone are you using now?

C: I don’t want to advertise too many phones, but whenever I have a new phone, I like to try it. I will try a new phone almost every 3 to 4 months, sometimes changing it for almost 6 months.

B: Google launched the first mobile phone not long ago. What is your evaluation? In addition, what is your opinion on the production of mobile phones by non-mobile phone manufacturers?

C: I hope that mobile phones can be evaluated by their value, not because of other gadgets. I haven’t used Google’s phone yet, so I can’t comment, but I predict that this is another “fun” phone.

B: What do you think of the future of mobile phones?

C: The future mobile phone will become smaller and smaller, maybe it will be put into the ear; maybe in the near future, the mobile phone can be implanted on the surface of your skin, always following you,

the energy in your body is enough for the mobile phone Power, so you never have to worry about forgetting to bring the charger; and when you want to call someone, just give the name and the phone will automatically dial out. [1]

No mobile phone can attract everyone

B: Do you have “mobile phone phobia”?

C: Each mobile phone has an “on/off” button. Users have to learn to arrange their own lives, and technicians can’t help.

B: How to reduce the radiation of mobile phones in the future?

C: Wireless communication is radiation, mobile phone radiation is very small, no one can prove that the harm of the mobile phone is more than the benefits.

 People who are worried about cell phone radiation (I don’t belong to this type of person) can find ways to keep the phone close to sensitive parts of their body. The biggest hazard of mobile phones is not radiation, but driving, many people are killed, but no one is a victim of cell phone radiation.

B: If you were asked to list the worst 5 mobile phones in history, what do you think is??

C: I don’t want to hurt any mobile phone manufacturer, but I can definitely list a few features of the “bad” mobile phone: 1) The buttons are too small and too dense, and the average person can’t get it right at once; 2

) The user interface is too complicated The manual is bigger and thicker than the phone, which is the characteristic of most mobile phones; 3)

 too many mobile phones (such as camera, Internet, music player, traffic navigation, various text messages, voice mail, etc.); There are too many features that cause each feature to be discounted for compatibility with other features.

B: If you want to list the best 5 mobile phones in history?

C: There is nothing special about the phone. I think Jitterbug is very different.

It was developed by my wife, produced by Samsung, and sold by Great Call. This is a simple mobile phone made up of simple services developed for the elderly.

 As long as people who use a fixed telephone and can understand the screen of a mobile phone , they can use it. As for the iPhone, it has a good interface for viewing photos and listening to music, and its role as a mobile phone is much less. There are many fanatics on the BlackBerry production line because it is made for this kind of person.

 No mobile phone can attract everyone’s attention. There will be many types of mobile phones in the future, which are very easy to operate for different people. [1]

Communication charges will be lower and lower

B: What is the most exciting thing besides inventing a mobile phone?

C: The most important thing is that our work makes providing mobile phone service an inevitable competition.

 If we didn’t win this war (I call the invention of a mobile phone a war), the United States will certainly have a monopoly, and the world is the same. Monopoly will not allow mobile phones to develop such a dynamic industry.

B: Why do you think people don’t enjoy cheap and high quality communication services?

C: This is because the cost of developing and applying new technologies for equipment and services takes a long time to come down.

Today, the cost of mobile services is only a fraction of the beginning of mobile service 25 years ago. If further costs are needed, newer technologies and services must be adopted.

B: Do you think mobile phone communication charges are reasonable?

C: Of course, the price is already very reasonable. Think about it, 3 billion people around the world use mobile phones. But the cost should be lower, and the price will go down along an empirical curve forever
