Blooming America

The 2nd year is a US person called Nesse Bufffield, in the countryside house in Murray in Kentucky, the first wireless mobile communication phone is human pair, and the mobile phone "technology earliest. Exploration Research.

In 1938, the United States made the world's first, mobile phone, mobile phone.

In August 1968, Martin Kutomo's first mobile phone in the world, using CDMA technology and integrated circuit, although it seems that such a mobile phone looks like a small suitcase, but also because this is the original product The reason, you can shrink it at a maximum of one or two years. If possible, maybe three years later, this phone will be available.

Because of this core of the spreading technology, CDMA is even more than the G ** and analog signals must be smooth. To say that the most important thing to do in this technology is undoubtedly a blockade of the United States **. In contrast, it is very simple to implement technology. This is why it is done in the federal government. After that, CDMA will immediately show the reason.

The technical core of g ** is the time division multiple access technology TDMA, which is evenly distributed to eight or sixteen mobile phone users, and each user interacts one-third of the channel time, because people call, The intermittent time between speech is actually very long, and only the voice coding is reasonable, and several users can share a channel.

And CDMA is more advanced, through code division multiple access technology, can make the call quality clamp, the amount of data transmission is more important, and because of the foundation, it is more easy to implement, but does not need Start research from scratch.

Hertrama, Mother, Qualcomm, became the Tax Officer of Waiting for Billion 3G users by her technology, because of this technology, Qualcomm is not done, and the annual profit is also Ability to bring them into the world to persuade.

As the first beauty of the New Hollywood, Hain Tilama is in the study room at the moment.

As a result of frequency hopping or spere, Lama can be said to be the most well, the US military has enabled research on frequency hopping technology, but fortunately, it is good to have the Ramarling machine and think of it. A method that can skip the control and creates CDMA technology. The technology itself is not limited, so as long as it can catch the vulnerability, it will break through. Besides, this patent itself is Hertrama. Moreover, the frequency hopping code divided multi-site fH - CDMA is used in private materials, and it is possible to use more general technologies. High technology is not necessary.

Hydie itself learned is a communication although he used to be an actor, but her poison is not pulled down, otherwise she is impossible to create a frequency hopping technology.

, Unfortunately, there is no way to miniaturize now.

Cooper is also coming back from Luo. He also mentioned the box in his hand.

Don't underestimate this box, in the box, in this various circuits, these are the foundation of this, mobile phone.

Of course, just just, the foundation ".

, We just do a verification test. If it is normal call, it should be possible to narrow the size of the landline. Heili looked at this later generation.

The time spent on the mobile phone is simply unimaginable. Every morning, Cooper must be the first person coming to the laboratory, and every afternoon, he must be the last time, sometimes, he will even live in laboratory.

CDMA technology Bibuli's wireless communication technology for car phone should be many, even if it is a genius like Cooper, it takes a certain time to understand.

But the way to Hitt is that Cooper's degree of CDMA technology is so fast, he is in order to sleep every day, for this mobile phone. Using ,,,,,,,,,,,,,,,,,,,,,,,,

, Kooper, I think you should take a break, perhaps a fake. "Hydi reminds the other party. Although, after death, it is greatly protruded by the Japanese, but if you don't rest for a while, you will be able to have the word with this word.

, Don't have to be, we need a real mobile phone, portable products that carry around. What is the Bell Lab? They have been out of time! "

The experience of being discriminated as before, and Cooper has never forgotten.

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

At this time, Catherine who can't wait to rush.

Miss Edison? Cooper turns back.

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

More than five years more than five years, Catherine thought that it had already earned it in advance, but did not expect it to be realized.

,,This is it. "

Pelica put his hand's suitcase.

, Is a test product, very inconvenient.

"Heand is obviously dissatisfied with this mobile phone, and we can also do more perfect."

, Yes, as long as it is not three years, maybe two years, or even a year, we can create mobile phones, real portable mobile phones! Think about it, everyone will carry our mobile phone products in everyone in the future, the sky, this is too wonderful, isn't it? "

Cooper is obviously more positive than Heti.

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

Catherine saw a strong dark circle in Cooper. Then she went back, and looked at this, mobile phone.

, Battery life is also a problem. The existing power supply is difficult to provide such an apparatus. If it is in the form of a dry battery, although it is possible, the stability is another question. "

Hydie's words make Catherine and Cooper temporarily calm down.

, Now the problem is still full ~ } There are a lot, if it is really applying, it is optimistic, maybe two years can be, pessimistic some ten years of coffee Edison, I think you'd better intend to intend to intend to intend to To prepare. ,

Ms. who has unique wisdom is very calm for things.

, Oh, right. "Catherine knows that Hetie has always wanted to prove his talent. Although this, she is so calm at the moment.

, Then, tell me your technology. "

Catherine mainly wants to listen to questions, which is the way to verify how many gaps from the previous world.

, We have built a base station in Luo Deyi and San Francisco, and other data have not been tested. We just verify the communication function. At least the base station and the place where I called, I only told Catherine in other situations of the mobile phone.

,, Um, then, next step we should test the base station, it is best to improve it. When you miniaturize your mobile phone, we can build a mobile phone base station in the United States, so that when you can use it, we can put production immediately. Catherine thoughtfully, then continued:, as for the battery problem, I will find a way to solve, if you don't know, you don't know if the lead battery can be

Catherine has long been very resentful for all kinds of batteries.

And she has long been prepared, and the Soros leads the entrepreneurial fund to invest in various energy industries. Isn't it necessary to need a suitable energy storage device?

Not necessarily the future lithium battery, as long as the same effect can be achieved, for Catherine, it is already enough.

Now is it to consider "Is there", but not thinking, good "is good."

Of course, the current lead battery can also be replaced, but the various problems that need to be solved are not as good as finding a new device. Most of the lead storage battery is a start type, that is, the class of instant current discharges If this device is used, it does not solve it is also troublesome, and it is possible to burn the board.

In addition, operations are also critical.

In this regard, the most famous example is that, the program "has a plan that does not rely on mobile phone base stations, but using satellite to implement a call.

Motorola has funded billions, then raised five billion funds, which took a whole 100 million US dollars to send you a satellite to the sky, to achieve, and all over the world. "But this star company is operated for one year Afterwards, I declare bankrupt.

This is not the problem of the project itself, a gate in one year, a private equity fund company (VATE-TY is bought at a low price of 2,500 million US dollars, the whole company has a $ 300 million turnover in just a few years and Hundreds of million profits.

The good product is given to the waste wood, which is also garbage.

Find a unwanted SEN, even if the most advanced technology is handed over to him, he will not be able to make money Motorola is a typical gate one in a later, Motorola even selling mobile phone throughout the mobile phone to Google, just like them. The TV industry is sold as a TV industry in the 1970s.

Although the phone has not yet appeared, it is also necessary. Historically, I'm planning to put into operation in an early investment is also a reason for its failure. A gate is that the bandwidth is narrow by insufficient satellite, which can't do anything in addition to calling.

Catherine was full of fighting spirit at this time, with the first-class, she won't commit the low-level mistakes, and it is also necessary to make the foundation well in advance.

But the exhibition of things, such as Heti, to consider from the worst angle
