Chapter 38: From analog to digital

When Fan Wubing was sent back, he basically returned home with a full load.

This time he gave the military a huge favor, and naturally he received quite generous rewards. There were no other things or the military, but when it comes to scientific research talents, it was basically the top figures in the country. Therefore, he carefully planned the issue of cooperation projects that Fan Wubing temporarily thought of.

"I want two hundred researchers with certain standards in communication, and it is best to be under thirty years old." Fan Wubing said to a lieutenant general in charge of negotiating with him.

"Two hundred?! You're crazy!" The lieutenant general was almost scared to death by Fan Wubing, and looked at Fan Wubing with an incredible look on his face and shouted, "If you want ten or twenty, we can consider it, two hundred?! You use to build satellites yourself?"

Scientific and technological talents in communication are originally very scarce, especially in recent years, the technology in the world's communications has been making rapid progress. As the army that is most sensitive and concerned about this, it is naturally impossible not to keep up with the development of world communication technology and strive to arm itself with the most advanced technology.

Therefore, communication talents are the most urgently needed and the most valuable talents in the army. Fan Wubing’s gambles and suddenly poached two hundred talents from them. Isn’t that a fantasy?

The lieutenant general's eyes were almost breathing fire when he saw Fan Wubing, just as Yang Bailao saw Huang Shiren, and the volunteer soldiers saw the American devils. He should be more vigilant.

Seeing the other party's expression, Fan Wubing couldn't help but sigh, thinking to himself, you are just too short-sighted and don't know that talents are not covered up, but released. Where can I build a car behind closed doors and gather the best in the world more effectively?

In short, if you want to poach people from the military, you must also focus on one key issue, that is, the military is short of money recently!

So Fan Wubing threw out his bait and said to him, "I'm just a borrower from you. People are still yours. In the years of borrowing, I will bear all the expenses. Moreover, we can earn half of the research results we have achieved, and no one will suffer any loss."

"That's not OK. It's not easy for us to train some talents. How can we give you two hundred people at once?" Although the lieutenant general's expression slightly relieved after hearing Fan Wubing's supplements, he still shook his head and refused to agree.

Fan Wubing frowned and said, "It's not humane! I have paid such a great price. It's not okay to borrow a few people from you. This matter is really unreasonable. How can we talk about cooperation again in the future?"

The Lieutenant General was speechless and thought to himself that you did sell us a favor, but you can't squeeze others like this, right? More than 200 communication talents are not more than 200 big-headed soldiers! If you borrow some special forces, or we can agree to it, but more than 200 communication talents will basically eliminate all the talents from one of our communications research institutes! Who could agree to you with such conditions?

"You want too many! Twenty or thirty can barely agree, but there will be no more!" Lieutenant General drank a sip of water, calming his mood that was so angry that Fan Wubing was slightly relieved, and then added, "And, we don't know what you want so many communication talents to do!"

Oh, this sentence is the key, right? Fan Wubing thought, probably I am still worried that I would do something shameful with so many people. Otherwise, although there were indeed a few 200 people, it would not be impossible to agree. In so many communications institutes in mainland China, which one can’t find two hundred people? Not to mention that there are colleges and universities specializing in cultivating various talents in the military. The accumulation over the years is not something ordinary people can imagine.

"I can't say what to do now." Fan Wubing was very nervous about this, "But let's talk about the conditions first. The treatment is very generous, and the rewards you get are also very generous. After passing this village, there is no such store!"

Although he didn't know what Fan Wubing wanted so many people to do, the lieutenant general was still very interested in the idea of ​​this freak genius under 18 years old. You should know that when the senior officials in the army mentioned Fan Wubing, they all said in unison that it was really a monster! So he asked, "Then let's talk about it for now. Let's study whether it is feasible. If I don't know anything, how can I explain it to the above?"

When Fan Wubing heard this, he knew that this matter could be discussed. The key was that the other party did not know his trump card, so he did not dare to agree rashly, so he pulled him down and slowly talked about his ideas. "I think the military's R&D capabilities and the technical skills of scientific researchers are pretty good, but what they lack the most is not the idea of ​​geniuses, the lack of innovative spirit, nor the low treatment, but the lack of an environment suitable for them to carry out research and development. If there is no environment where one can display his talents, even the genius will eventually be exhausted in silence."

The Lieutenant General nodded, and he still recognized Fan Wubing's words. The domestic economic foundation is too poor, and the military naturally lacks the allocation. Some research projects are very expensive, and even if the country wants to bear it, it is a bit difficult. After all, the focus of the country is to develop the economy. Various industries need to increase investment. The funds that can be obtained from the military are very limited, and the funds obtained by scientific research institutions are also very limited. Many places are basically maintaining. If you want to be pioneering and enterprising, it is just a blank saying. If you have no money, what should you use to do scientific research and projects?

"What do you want to say, you might as well say it straight. There is no need for us to go around in circles like this." In the end, the Lieutenant General said to Fan Wubing.

"I want to use civilian digital mobile communication technology!" Fan Wubing finally gave up his own ideas.

Civilian digital mobile communication technology?! Lieutenant General was stunned after hearing this. He never thought that Fan Wubing had such a big appetite! This is him. I guess someone else came to negotiate with Fan Wubing, and I still don’t know what the digital mobile communication technology Fan Wubing mentioned is!

"Digital mobile communication technology? And it's civilian?" Lieutenant General had to repeat it to determine whether Fan Wubing was just talking nonsense.

Since the birth of the first generation of analog mobile phones in the late 1970s, Big Brothers has begun to appear in people's sight. A major achievement of the first generation of wireless network technology is to remove the user line connecting the phone to the network, and users can receive and make calls wirelessly in a mobile state for the first time. At this time, there are three main narrowband simulation standards, namely North American cellular system amps, Nordic mobile phone system nmt and fully access communication system tacs.

In the 1980s and early 1990s, simulated hive mobile communications represented by two major technologies, amps and tacs, reached its heyday. However, it was precisely because of the widespread application that its shortcomings were increasingly exposed, such as poor call quality, poor confidentiality, easy to be eavesdropped, poor security, easy to be stolen, poor roaming, poor business functions, and only voice-only function services. These problems are becoming increasingly prominent. It should be pointed out that these problems are not technical problems of the product, but problems of the technical system itself.

Therefore, since the mid-1980s, new digital communication systems such as gsm, d-amps, and pdc have been successively launched in the international community, which adopts time division multiple access TDMA technology and code division multiple access CDMA technology represented by is-95.

This digital mobile communication technology adopts advanced source encoding, such as voice compression, channel encoding, such as forward error correction and advanced multiple access technology, so that on the basis of digitalization, multiple information can be integrated, new services such as short message transmission have emerged, and various value-added services can be launched.

Through advanced digital signal processing technology, the anti-interference and anti-fading capabilities of information during transmission are greatly enhanced, and the transmission quality and security and confidentiality are improved at the same time. Through advanced multi-user processing technology, the capacity of the entire system is greatly improved, that is, with the same spectrum bandwidth, the digital communication system can accommodate several times the number of users in the analog system.

That is to say, digital systems can enable limited spectrum resources to provide higher quality communication services to more users. Because of this, governments and enterprises around the world, including operators and equipment manufacturers, have all worked hard to promote this digital revolution in mobile communications.

But now, domestic digital mobile communication technology is far from being widely used, so it is a bit surprised to hear Fan Wubing say that he wants to use civilian digital mobile communication technology.

In 1992, China was still in a period of rapid development of simulated mobile communications, with more than 5 million users. So far, there has been no sign of the possibility of developing digital mobile communications technology in China.

Others may not understand this kind of problem after hearing it, but this lieutenant general happened to be in charge of research on communication technology. He should understand some general direction issues and the current situation of domestic communication technology. Therefore, the lieutenant general had to ask, "If you talk about military technology, or I would still believe it, but if you talk about civilian digital mobile communication technology, it would be a bit outrageous. You should know that the simulated mobile communication network has formed a certain scale and the number of users is also increasing sharply. If that is the case, how can you develop another set of digital mobile communication technology? Isn't that equivalent to repetitive construction?"

The meaning of the lieutenant general is very clear. It is impossible for the country to spend so much money to develop another set of mobile communication technology. Even if you develop a complete set of technologies, if you do not get approval, those technologies can only stay on paper.

You should know that the emergence of the big brothers and big brothers meant that China entered the era of mobile communications. In 1987, in order to connect with Hong Kong and Macao, Guangdong took the lead in building a 900mhz analog mobile phone. Motorola also set up an office in Beijing to promote mobile phones. This heavyweight mobile phone is thick and bulky, shaped like a black brick, and weighs more than one pound. It has no other functions except making phone calls, and the call quality is not clear and stable enough, so it often has to shout. After charging a large battery, it can only last for 30 minutes to make calls.

Even so, the big brother is still very short of money and it is hard to find money. The big brother's open price was around 20,000 yuan, but it usually costs about 25,000 yuan to buy it. The black market price was once as high as 50,000 yuan. This not only discouraged ordinary people, but also not many small and medium-sized enterprises can afford it.

Extroverted people will hold their elder brother in their hands all day long to negotiate for meals and tea, and put them on the table, just like betting on a wealthy bargaining chip and scepter, which will immediately gain more respect, and business negotiations will become easier. People with restrained personalities will put their elder brother in the shiny boss bag, and the boss is double-tied under their armpits. Take it out at the appropriate time, pull out the long antenna, spend a one-yuan and a minute call, and shout in the crowd, "Hey! Hey! I can't hear clearly, you can say it again." This attracted countless envious eyes.

In this case, simulated mobile phone networks basically represent the interests of the people who became rich first in China. The cost of investing in a huge telephone network and the high cost of telephone equipment will inevitably lead to these big guys not being eliminated so easily. Therefore, the lieutenant general felt that what Fan Wubing said was not operational.

Fan Wubing also knows the resistance encountered by China in promoting digital mobile communication technology. This resistance has enabled the simulated mobile communication network to be completely shut down until two thousand years later. Although user obstruction is one of the reasons, the bigger problem is that the vested interests of the simulated mobile communication network are at work.

After careful consideration, Fan Wubing said to the lieutenant general, "Every social change means that some people have to gain benefits and some people have to suffer losses, which is inevitable. However, we cannot give up the opportunity to make progress just because of a small number of people's little interests. This is the case with the current domestic reform process, and the development of communication technology is the same. For simulated mobile phone networks, it occupies too much spectrum! With the future development of communication technology, simulated mobile phone networks will inevitably be eliminated. New technologies replace old technologies and new products replace old products, which is inevitable for social progress. What I need to do now is to accelerate the process of alternation between new and old, so that China's communication technology can try its best to be at the forefront of countries in the world, rather than waiting for other countries to mature technologies and treat us as the world's largest finished product dumping market."

"Can you be sure that the direction you chose is the right one?" After hearing Fan Wubing's words, the Lieutenant General was silent for a while. He needed to think about the joints in it carefully, and finally he asked.

He did not want his technical talents to become victims of Fan Wubing's wrong decisions. Even three years would make these people seriously disconnected from what they were originally studying. This is not in the interests of the military, unless things are really as fascinating as Fan Wubing described.

"No one can guarantee this." Fan Wubing replied with a smile. When he saw the lieutenant general's face a little disappointed, he added very cunningly, "Any success comes at a price."

The Lieutenant General was amused by Fan Wubing's cunning, and finally had to answer, "I need to listen to the opinions of experts, and the internal team also needs to conduct relevant discussions. How about you later?"

"No problem, but time should be as fast as possible. I probably don't have much time. If it really doesn't work, this piece of fat will have to be cheaper for foreigners." Although Fan Wubing said he was urging the other party, he had to make plans to be rejected.

The market for the second-generation mobile phones is really too big. Although it is a bit early now, in the original history, the launch of digital mobile communication network in China was only two years later, and the time was not very abundant.

The most important thing is that Fan Wubing now has the communication satellite resources covering most of the earth. With this background, he should of course vigorously develop digital mobile communication network technology, mobile phone market, and digital communication market. This big cake is enough to make all the big conglomerates salivate.

Moreover, Fan Wubing is still thinking that if he can master the core technology of the digital communication network, he will likely provide this service to the outside world, and his communication satellites will not become wasteful resources.

"What are you thinking about? So engrossed?" Lin Xiaotong lay on the hospital bed, looking at Fan Wubing in contemplation, and couldn't help but ask.

Lin Xiaotong's physical condition has recovered very quickly these days, and Fan Wubing felt a little surprised, but when he thought of the speed of Lin Xiaotong's explosion in order to block bullets for his father Fan Heng, he could basically confirm that Lin Xiaotong's identity is definitely not simple.

At least, she is also a special talent who has practiced internal skills. Otherwise, it would be impossible for ordinary people to burst out such powerful speed and power in an instant. Her current super recovery ability seems to confirm Fan Wubing's guess about this.

Therefore, Fan Wubing replied casually, "I'm wondering, what is your identity?"

Sure enough, after hearing Fan Wubing's words, Lin Xiaotong's face became unnatural for a moment, but she quickly said angrily, "You don't know what identity you have? Isn't it your father's secretary? Do you think I have other identity?"

Fan Wubing smiled and did not refute her. Anyway, no matter what Lin Xiaotong's identity is, she is her father's savior. Just for this, Fan Wubing can't do anything to her. But according to the general situation, Lin Xiaotong should probably be the secret agent sent by the superiors to monitor and protect Fan Heng's safety?

Lin Xiaotong's body gradually recovered, and Fan Heng gradually added many tricks to the food she ate to find. The combination of meat and vegetables was very reasonable, and the suggestions of many nutritionists were integrated, which were all conducive to her physical recovery.

However, whenever I see the pile of rich foods prepared by Fan Wubing, Lin Xiaotong has a little painful expression, "Can I eat less? I can't lie down all day and can't move, and I have to eat so much food. Do you think I'm a pig?"

"No?!" Fan Wubing looked at Lin Xiaotong and said, "I think your figure is still as devilish as before!"

"But I think my waist is much bloated-" Lin Xiaotong said with some distress.

"No way - why can't I see it at all?" Fan Wubing looked left and right, but he couldn't find that Lin Xiaotong's waist would be bloated. On the contrary, he felt that this waist was really curved and quite demonic!

"Of course you can't see it with your eyes. If you don't believe it, please touch it with your hands." Lin Xiaotong said.

Is that right? Fan Wubing didn't think much about it. He and Lin Xiaotong have become more and more familiar with each other these days, so he put down the spoon and reached out to touch it without thinking. Well, Lin Xiaotong's small waist is very soft and the thickness is just right. I didn't find any fat at all. It's so good!

At this time, Fan Ting suddenly pushed the door and came in. She immediately saw Fan Wubing sitting on the bed with his eyes blank, stretching out his hands to touch Lin Xiaotong's waist. Lin Xiaotong also looked very natural and couldn't help but say fussingly, "Ah! Is it inappropriate for me to come?!"

Uh?!Fan Wubing suddenly woke up and found that his hands were not only placed on Lin Xiaotong's waist, but also moved upwards involuntarily. How did this misunderstanding happen?

Looking at the old sister Fan Ting with an ambiguous smile standing at the door and refused to come in, Fan Wubing suddenly felt speechless.
Chapter completed!
