[Please keep in mind the domain name of this site " " , or search in Baidu: Sanlian Literature Network] When Fan Wuxian was sent back, he was basically a full return.
He gave the military a great favor this time, and naturally he got quite a rich return, other things or the military did not, but when it comes to scientific research talents, this is basically a net of the top people in China, so the question about the cooperation project that Fan Wuxi thought of temporarily was seriously planned by him.
"I want 200 researchers with a certain level of proficiency in communications, preferably under the age of 30." Fan Wuxian said this to a lieutenant general who was in charge of negotiating with him.
"Two hundred?! You're crazy! The lieutenant general was almost frightened to death by Fan Wuxi, and looked at Fan Wuxian with an incredulous face and shouted, "If you want ten or twenty, we can still consider considering, two hundred?!" You used it to build your own satellite?! β
In particular, in the past few years, the entire world's telecommunications technology has been advancing by leaps and bounds, and it is naturally impossible for the military, which is most sensitive and concerned about this, not to keep up with the pace of the development of the world's telecommunications technology and strive to arm itself with the most advanced technology.
Therefore, the talents in communications, but the most urgently needed and most valuable talents in the army, Fan Wuxian Lion opened his mouth widely, and he will poach 200 talents from them at once, isn't that a fantasy?
The lieutenant general looked at Fan Wuxi's gaze at this time, and he was almost a little spewing fire, just like Yang Bailao saw Huang Shiren, and the volunteer soldiers saw the American devils, they should be as vigilant as they wanted.
See each other's expressions. Fan Wuxian couldn't help but sigh, and said in his heart, you guys, it's just that your vision is too short-sighted, I don't know that talents are not covered out, but released, where is it more effective to gather the world's leaders behind closed doors?
All in all, want to poach people from the military. The key issue is to grasp one key point, that is, the military has been short of money recently!
So Fan Wuxian threw out his own bait. He said to him, "I'm not poaching people from you, borrowing them, people are still your people, and during the years of borrowing them, all the expenses will be borne by me, and. We can divide the research results in half, and no one will suffer a loss. β
"That's not good, it's not easy for us to cultivate some talents, how can we give you two hundred people at once?" Although the lieutenant general's expression eased slightly after listening to Fan's injury-free addition, he still shook his head and refused to agree.
Fan Wuxian said with a frown. "It's not human! I've paid such a big price, and I can't borrow a few people from you, it's a bit too much to say. After that, how can we talk about cooperation again? β
The lieutenant general immediately opened his mouth and said in his heart, You did sell us a big favor, but you can't squeeze others like this, right? More than 200 communication talents. It's not more than 200 big-headed soldiers! If you borrow some special forces, or we can all agree, but there are more than 200 communication talents, which basically drains all the talents of one of our communication research institutes! Who can agree to such conditions?
"You want too much land! Twenty or thirty can barely agree, and there will be no more! The lieutenant general took a sip of water, calming down his mood a little from being choked by Fan Wuxi's anger, and then added, "Besides, we don't know what you want so many communication talents to do!" β
Oh. That's the key, right? Fan Wuxian thought to himself. I guess I'm still not worried about what I use so many people to do something unseemly, otherwise. Although two hundred people are indeed a bit much, it is not impossible to agree, so many communication research institutes in Chinese mainland, which one can't find two hundred people? Not to mention that there are academies and academies in the military that are specially responsible for cultivating all kinds of talents, and the accumulation over the years is beyond the imagination of ordinary people.
"I can't say exactly what I did." Fan Wuxi bit very tightly about this, "However, let's talk about the conditions first, the treatment is very generous, and the rewards you get are also very generous, but there is no such shop in this village!" β
Although he didn't know what Fan Wuxian wanted so many people to do, the lieutenant general was still very interested in the idea of this freak genius who was less than eighteen years old, you must know that when the high-ranking people in the army mentioned Fan Wuxi, they all said in unison, it was really a demon! So he asked, "Then let's talk about it, let's study whether it is feasible." If I don't know anything, how can I explain it to the above? β
As soon as Fan Wuxian heard Lieutenant General's words, he knew that this matter could still be discussed, and the key was that the other party didn't know his hole cards, so he didn't dare to agree rashly, so he pulled him to sit down and slowly talked about his ideas, "The military's research and development capabilities, the technical skills of scientific researchers, I think it's still good, but what they lack the most is not genius ideas, not lack of innovative spirit, not too low salary, but there is no suitable environment for them to conduct research and development." If there is no environment where you can give full play to your talents, no matter how talented a character is, he will eventually die in silence. β
The lieutenant general nodded, for Fan Wuxi's words, he still agreed, the domestic economic foundation is too poor, the military has received insufficient funds, some research projects, but it is very money-burning, even if the country wants to afford it, it is also a little difficult, after all, the key direction of the country is to develop the economy, all kinds of industries need to increase investment, the funds that can be obtained by the army are very limited, and the funds that scientific research institutions get are also very limited. It's just an empty word, if you don't have money, what can you do with scientific research and projects?
"If you want to say anything, you might as well say it, we don't need to go around in circles." Finally, the lieutenant general said to Fan Wuxi.
"I want to engage in digital mobile communication technology for civilian use!" Fan Wuxian finally threw out his thoughts.
Digital mobile communication technology for civil use?! The lieutenant general was stunned when he heard this, he didn't expect anything. Fan Wuxi's appetite is so big! This is also him, it is estimated that someone else will come to negotiate with Fan Wuxi, and he doesn't know what this digital mobile communication technology is that Fan Wuxian said!
"Digital mobile technology? And still civilian? The lieutenant general had to repeat it to determine whether Fan Wuxian was just talking.
Since the late 70s, with the birth of the first generation of analog mobile phones, Big Brother has been in the limelight, and one of the great achievements of the first generation of wireless network technology is the elimination of the user lines that connected the phone to the network. For the first time, users will be able to receive and make calls wirelessly while on the move. At this time, there are three main narrowband analog standards, which are the North American Cellular System AMPS, the Nordic Mobile Phone System NMT, and the Total Access Communications System TACS.
By the eighties and early nineties. Analog hive mobile communication, represented by the two major technologies of AMPS and TACS, has reached its heyday. However, it is precisely because of the common application that its shortcomings are becoming more and more violent, such as poor call quality, poor confidentiality, easy to be eavesdropped, poor security, easy to be stolen, poor roaming function, poor business function, only voice single function service, etc., these problems are becoming more and more prominent. In particular, it should be pointed out that these problems are not the technical problems of the product, but the problems of the technical system itself.
So, from the mid-eighties. In the world, GSM, D-AMPS, PDC and other new digital communication systems adopting time-division multiple access TDMA technology and code-division multi-access CDMA technology represented by IS-95 have been launched in the world.
This digital mobile communication technology adopts advanced source coding, such as voice compression, channel coding, such as forward error correction and advanced multiple access technology, so that on the basis of digitalization, a variety of information can be integrated, new services such as short message sending have emerged, and various value-added services have also been developed.
Through advanced digital signal processing technology. The anti-interference and anti-fading ability of information in the transmission process has been greatly enhanced, and the transmission quality and security and confidentiality have been improved at the same time. Through advanced multi-user processing technology, the capacity of the whole system is greatly improved, that is, with the same spectrum bandwidth, the digital communication system can accommodate several times the number of users of the analog system.
That is, digital systems can enable limited spectrum resources to provide higher quality communication services to a larger number of users. Because of this. Governments and businesses around the world, including operators and device manufacturers, are all contributing to this digital revolution in mobile communications.
However, at present, the domestic digital mobile communication technology is far from reaching the point of large-scale application, so when the general heard Fan Wuxian say that he wants to engage in civilian digital mobile communication technology, he was a little surprised.
In 1992, China was still in a period of rapid development of analog mobile communications, with more than 5 million users, and so far there has been no indication of the possibility of developing digital mobile communication technology in China.
This kind of question may not be clear to others, but this lieutenant general happens to be in charge of research in communication technology. It is necessary to understand some general direction of the problem. Also aware of the current state of domestic communication technology, so the lieutenant general had to ask. "If you say that you are engaged in military technology, or I will still believe it, but if you want to say that you are engaged in civilian digital mobile communication technology, it is a bit outrageous, you must know that now the analog mobile communication network has formed a certain scale, and the number of users is also rising sharply, in this case, how can it be possible to engage in a set of digital mobile communication technology? Isn't that the same as repetitive construction? β
The meaning of the lieutenant general is very clear, it is impossible for the state to spend so much money on another set of mobile communication technology, even if you come up with a whole set of technology, but if you do not get approval, those technologies can only stay on paper.
You must know that the emergence of Big Brother means that China has entered the era of mobile communications. In 1987, in order to achieve mobile communication integration with Hong Kong and Macao, Guangdong took the lead in building a 900MHz analog mobile phone. Motorola has also set up an office in Beijing to market mobile phones. This kind of heavyweight mobile phone is thick and bulky, shaped like a black brick, and weighs more than a pound. It has no other functions except for making calls, and the call quality is not clear and stable enough, so it often has to be shouted. When a large battery is charged, it can only last 30 minutes of calls.
Even so, Big Brother is still very in-demand and money is hard to find. At that time, the public price of Big Brother was about 20,000 yuan, but it usually costs about 25,000 yuan to buy it. The price on the black market was as high as 50,000 yuan, which not only discouraged ordinary people, but also small and medium-sized enterprises could not afford to buy land.
Extroverts will hold Big Brother in their hands all day long, eat and drink tea to negotiate, and put it on the table, just like betting on a rich chip and scepter. Immediately you will gain more respect and business negotiations will be easier. A person with a restrained personality. Will put Big Brother in a polished boss bag, which is tucked under the armpit. When appropriate, take it out, pull out a long antenna, spend a dollar a minute, and shout in the crowd, "Hey! Feed! I can't hear clearly, you say it again. It attracted countless admiring glances.
In this case. The analog mobile phone network basically represents the interests of the part of the people and land that got rich first in China, and 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, so the lieutenant general feels that what Fan Wuxian said is very inoperable.
Fan Wuxian is also aware of the resistance encountered in the promotion of digital mobile communication technology in China. Although user obstruction is one of the reasons, the bigger problem is that the vested interests in analog mobile communication networks are at work.
After thinking about it carefully, Fan Wuxian said to the lieutenant general. "Every social change means that some people have to gain and some people have to suffer losses, which is inevitable. However, we must not give up the opportunity to make progress because of the small interests of a small number of people, and this is exactly what is happening in the reform process in China, as is the development of telecommunications technology. For an analog mobile phone network, it takes up so much spectrum! With the development of communication technology in the future. Analog mobile phone networks are inevitable. New technology replaces old technology. New products replace old products, which is the inevitable progress of society. And what I'm going to do now. It is to speed up the process of replacing the old with the new, so that China's telecommunications technology can be at the forefront of all countries in the world as much as possible, instead of waiting for other countries to become mature and regard us as the world's largest dumping market for finished products. β
"Can you be sure that you're going in the right direction?" After listening to Fan Wuxi's words, the lieutenant general was silent for a while, he needed to think about the joints in it, and finally he asked.
He didn't want his technical talents to fall victim to Fan Wuxi's wrong decision-making, even if it was three years, it would make these people seriously drag themselves from what they had previously studied, which was not in the interests of the military, unless, things were really as fascinating as Fan Wuxian described.
"No one can guarantee that." Fan Wuxian replied with a smile, and when he saw the lieutenant general's face was a little disappointed, he added very slyly, "Any success comes at a price." β
The lieutenant general was so embarrassed by Fan Wuxian's cunning that he finally had to reply, "I need to listen to the opinions of experts, and the internal team also needs to have relevant discussions, and I will answer you later?" β
"No problem, but the 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 than foreigners." Although Fan Wuxian said that he was urging the other party, he had to be prepared to be rejected.
It is really the market of the second generation of mobile phones is too big, although it is a little early to start now, but in the original history, the domestic launch of digital mobile communication networks, it is only two years later, and the time is not very abundant.
The most important thing is that Fan Wuxian now has the communication satellite resources covering most of the world, and with the support of this background, he should of course vigorously develop digital mobile communication network technology, the mobile phone market, and the digital communication market, which is enough to make all the big consortia salivate.
Moreover, Fan Wuxian is still imagining that if he can master the core technology of digital communication networks, then it is very likely that he will provide services in this regard, and his own communication satellites will not become wasted resources.
"What are you thinking, so engrossed?" Lin Xiaotong was lying on the hospital bed, looking at Fan Wuxian in contemplation, and couldn't help but ask.
In the past few days, Lin Xiaotong's physical state has recovered quickly, and Fan Wuxian felt a little surprised, but when he thought of the speed at which Lin Xiaotong broke out at the moment when he blocked the bullet for his father Fan Heng, he could basically be sure that Lin Xiaotong's identity was definitely not simple.
At the very least, she is also a special talent who has practiced internal strength, otherwise it would be absolutely impossible for ordinary people to burst out with such powerful speed and strength in an instant, and her current super recovery ability seems to confirm Fan Wuxi's speculation about this.
Therefore, Fan Wuxian replied casually, "I'm wondering, what is your identity?" β
Sure enough, after Lin Xiaotong listened to Fan Wuxi's words, her face was unnatural for a moment, but she quickly said with disgust, "What identity do you not know yet?" Isn't it your father's secretary, what other identity do you think I have? β
Fan Wuxian smiled and didn't refute her, anyway, no matter what Lin Xiaotong's identity is, after all, he is his father's savior, just for this point, Fan Wuxian can't do anything to her, but according to the general situation, probably Lin Xiaotong should be a secret agent sent from above to monitor and protect Fan Heng's safety, right?
Lin Xiaotong's body gradually recovered, and Fan Heng gradually added a lot of tricks to the food and employment she ate, the meat and vegetable combinations were very reasonable, and the suggestions of many nutritionists were more comprehensive, which were conducive to her physical recovery.
However, every time he saw the pile of sumptuous food prepared by Fan Wuxi, Lin Xiaotong had a slightly painful expression, "Can I eat less?" Lying down all day and not moving, and eating so much food, you raise me like a piglet? β
"No?!" Fan Wuxi looked at Lin Xiaotong and said, "I think your figure is still the same as before!" β
"But I think my waist is a lot bloatedβ" Lin Xiaotong said with some distress.
"Noβwhy can't I see it at all?" Fan Wuxian looked left and right, but he didn't find that Lin Xiaotong's waist would be bloated, on the contrary, he felt that this waist was really curvy, quite demonic!
"Of course you can't see it with your eyes, I don't believe you can touch it with your hands." Lin Xiaotong said.
Is it? Fan Wuxian didn't think much about it, he and Lin Xiaotong have become more and more familiar in the past few days, so he put down the spoon and reached out to touch it without thinking about it, well, Lin Xiaotong's small waist is very soft, the thickness is just right, and he didn't find the slightest fat, which is very good!
At this time, Fan Ting suddenly pushed the door in, and immediately saw Fan Wuxi sitting on the bed with blank eyes, stretching out his hands to touch Lin Xiaotong's waist, and Lin Xiaotong also looked very natural, and couldn't help but fuss and said, "Ah! Am I not at the right time?! β
Belch?! Fan Wuxian suddenly came to his senses, and found that his hands were not only on Lin Xiaotong's waist, but also involuntarily moved upward, how did this misunderstanding happen?
Seeing the old sister Fan Ting with an ambiguous smile standing at the door and refusing to come in, Fan Wuxi suddenly felt a little speechless.
Why did the misunderstanding happen so inadvertently?
Today, I was surprised to see that the blood red giant has returned to the starting point, which is very good and powerful! **************οΌ ~οΌ [To quickly find this site, please search in Baidu: Sanlian Literature Network]
