1902.

One is called.

Nensivetabfield.

The Americans made the first wireless telephone device in the rural houses in Kenkawa Merri. This wireless mobile phone call is the earliest exploration and research of human beings, mobile phones ".

In 1938, the Midea Bell Lab was made into the world's first part for the US military, mobile phone,.

cell phone.

In August 1968, Martinkopper invented the world's first mobile phone pushing to civilian, using CDMA technology and integrated circuits. Although this mobile phone seems to be as huge as a small handbox, it is also because it is the beginning of the beginning

For the product, at most one or two years, it can be reduced. If possible.

Maybe three years later, this phone can be available.

Because of the core of the frequency bosom technology, the development of CDMA development is even more smooth than the GSM and analog signal. The most important thing to do on this technology is undoubtedly bypassing the blockade of the US military.

In contrast, it is very simple to achieve technology. This is why the CDMA immediately developed after the federal government lifted the ban.

The core of the GSM technology is TDMA, which is time -to -site technology TDMA, to be evenly divided into eight or sixteen mobile users with each wireless frequency.

The interval time is actually very long. Only the voice coding is reasonable, and a few users can share a channel.

However, the CDMA is more advanced. Through the code division of multi -site technology, the quality of the call can be folded well, and the data transmission volume can be greater.

The most important thing is that because there is already a foundation to develop, it can be achieved easier, and there is no need to start research from scratch.

Heidirama, the mother of CDMA, Qualcomm has become the tax collector of the 2 billion users in the next 2 billion users through the technology left by her. Because of this technology, even if Qualcomm does not do anything, the profit generates every year

Can also bring them into the world to persuade.

As the first beauty of Hollywood in the age, Heidirama was drilling in the laboratory at this moment.

As the creator of frequency jump or exhibition technology.

Lama can be said to know the most about his technology. The US military's frequency -jump technology control has entered the predicament, but fortunate

CDMA technology is created. The technology itself is not limited, so as long as you can catch the loopholes, you can break through it. Besides.

This patent itself is Heidirama's own. And the frequency jump code is divided into multi-site FH-CDMA for the people, it is also large and small, it is enough to use it.

The major learned by Heidi itself is communication.

Although she was an actor, her poisoning industry was not pulled down, otherwise she would not be able to create frequency jump technology.

Unfortunately, there is no way to be small yet. "

Cooper also returned from Luoyan alum at this time. At this time, he was still holding that box in his hand.

Don't underestimate this box, in the box.

It is installed in this variety of circuits here, these are the basis of the operation of this, mobile phone.

Of course, just, the foundation ".

We just do a verification test. If it is a normal call, the size of the landline should be possible. "Heidi looked at the younger generation.

Cooper spent on the phone that it is hard to imagine. Every morning, Cooper must be the first person to come to the laboratory, and every afternoon, he must be the last one to go back.

laboratory.

CDMA's technology is much more advanced than the wireless communication technology for vehicle telephone research. Even a genius like Curpper, it takes a certain time to understand it.

But what Hainti didn't expect was that the speed of Curper's mastery of CDMA technology was so fast. He used to sleep and eat every day, just for this kind of mobile phone. The word of the mobile phone. "

, Cooper, I think you should need to rest for a while, maybe a fake or something. "Heidi reminded the other party with kindness. Although, the death and death" is promoted by the Japanese, but if the Cooper in front is

If you rest for a while, it is likely that you will have a relationship with this word.

, No, we need a real mobile phone, a portable product that is carried with us. What is Bell Labs? They are out of date! "

In the past, Curob has never forgotten.

,, Where is the phone? Where is the mobile phone?! "

At this time, Catherine, who couldn't wait, also rushed over.

,, Miss Edson?,.

Cooper turned around.

, Ah, Ms. Cooperlama, your mobile phone has been successfully developed?,.

It has been five years earlier than in history.

Catherine thought that it could have made a lot of hair in two years in advance, but I did not expect to be realized now.

This is this. "

Putting his hand -made boxes down.

It is just a test product, which is very inconvenient.

"Heidi is obviously dissatisfied with this kind of mobile phone ,,, we can still be more perfect."

, Yes, as long as three years, maybe two years, or even a year, we can create a mobile phone, the real portable mobile phone! Think about it, everyone will carry us in our hands in the future

Mobile phone products, oh my god, this is so wonderful, isn't it? "

Cooper is obviously more active than Heidi.

,, I think I should give you a vacation first. "

Catherine saw the thick dark circles of Cooper. Then she turned around and looked at this one, mobile phone ".

The battery life is also a problem. It is difficult for the existing power supply to provide such equipment. If it is used in the form of a dry battery, although it is possible, the stability is a question.

..

..

"

The words of Heidi let Catherine and Cooper calm down for the time being.

, Now the problem is still tidy ~ there are many things. If it is really applied, it may be more optimistic, maybe two years, and pessimism for about ten years.

..

..

Miss Edson, I think you'd better prepare for the worst plan.

This lady with unique wisdom.

Calm about things about things.

, Oh, right. "Catherine knew that Heiti always wanted to prove her talents. Despite that, she was so calm at this moment.

,, Then tell me your technology. "

Catherine mainly wants to listen to some questions about mobile phones. By the way, verify how much this is from the previous world.

We have set up a base station in Luo Shulin alum and San Francisco. Other data have not been tested for the time being. We just verify the communication function. At least 150 meters away from the base station and the place where I call.

At present, there are only these "Cusper told the other situation of the mobile phone to Catherine.

, Well, then, we should test the base station in the next step. It is best to improve it. When you minimize your mobile phone, we can just build a mobile base station in the United States. In this way, when the mobile phone can be used, we can use it.

We can put it into production immediately. "Catherine thought about it, and then continued:, as for the battery problem, I will find a way to solve it.

Catherine has long been very resentful about various batteries.

And she has long been planned and asked Soros to lead the entrepreneurial fund to invest in various energy industries. Isn't it just to need a suitable energy storage equipment?

It is not necessarily a lithium battery in the future. As long as it can achieve the same effect, it is enough for Catherine.

It's time to consider "whether there is", not thinking, okay ".

Of course, the current lead battery can also be replaced, but the various problems that need to be solved are piled up.

..

..

It is better to find a new device. Most of the lead batteries are started, which is the type of large current discharge.

If you use this device, do not solve various problems.

That's also trouble. If you accidentally burn the circuit board.

In addition, operation is also the key.

In this regard, the most famous example is that, the Star Program "a plan that does not rely on mobile phone base stations, but a plan to use satellites to realize calls.

Motorola invested 1 billion, and then raised 5 billion yuan, which consumed a total of 6 billion U.S. dollars to send a satellite to the sky.

One year later, I announced bankruptcy.

This is not a problem of the project itself. In 2001, after the PMIVATE-EPUITY was bought at a low price of $ 25 million, the entire company had a turnover of 300 million US dollars in just a few years and the turnover.

50 million profits.

Good products are handed over to waste wood, that's also garbage.

Finding an indifferent Losen, even if he handed him the most advanced technology, he may not be able to make money.

Motorola is a typical grid one later. Motorola even sold the mobile phone business to Google, just as they sold the TV industry in the 1970s.

Although the mobile phone has not yet appeared, the fate of Weiyu silk is also necessary. Historically, it is also a reason for the fact that it is also a reason for the fact that Yixing plans to invest in operations.

I can hardly do anything outside.

Catherine is full of fighting spirit at this time. With the lessons of the car, she will not make those low -level mistakes. It is also necessary to lay the foundation in advance.

But as Heidi said, the development of things must be considered from the worst perspective.
