As a new academician of the Academy of engineering, Gu Xueli is the general director of the national Torch Plan - mobile communication project.

Wu Tao came to ask him about it. Naturally, it was most appropriate.

However, upon hearing this tone, Gu Xueli immediately said, "do you think these basic technologies are farmers' farming? Sow in spring and harvest in autumn? "

Wu Tao is not angry. After all, as a younger generation, he knows Lao Gu's temper.

Besides, Lao Gu is so vigilant. Most of them are in the previous cooperation in mobile phone prototype design. They are in a bit of a hurry.

So he smiled and said, "Grandpa, as the saying goes, you get what you sow, and you get what you sow. Now that we put in, we have to have a harvest, don't we? Even if we don't have it now, when we can have it, we have to have a general letter, don't we? "

At this time, Yin Wenfang brought the fruit tray. When he saw his wife blowing her beard and staring, he couldn't help complaining for Wu Tao: "it's rare for children to ask you something, so we can't say it well?"

"Go, you old woman, don't know anything. Don't interrupt!" It seems that old Comrade Gu has become an academician. He is also a little angry. I dare not do this before I put it away.

Fortunately, Yin Wenfang was not annoyed. Just patted Wu Tao on the shoulder and said comfortingly, "Tao, don't worry about him. He's just such a cow."

When Yin Wenfang left, Gu Xueli sighed: "now the torch plan faces two major problems. First, the National IC industry has no foundation, and the comprehensive layout needs planning and time; Second, when the expert group chose which way to go, there were differences. How to choose GSM and CDMA? "

Listening to these two words, Wu Tao feels both familiar and strange.

GSM is a technology in the 2G era, which has been popular until nearly a decade later; However, CDMA should belong to 3G technology. How can it be compared?

Then he asked without hesitation: "what's the difference between GSM and CDMA?"

Gu Xueli put his thin palm on his knee, "technically, CDMA is more mature and advanced. It was created by Qualcomm and transformed from the military. It uses code division multiplexing technology. "

"... GSM is a time-sharing multiplexing technology. It is the standard developed by Europeans. Relying on the advantages of early implementation, it is now the most widely used."

"... technically speaking, the user capacity of CDMA is more than 10 times that of GSM, and the signal is clearer and not easy to be eavesdropped."

"... however, Qualcomm has registered a large number of patents in the CDMA standard. If other countries and organizations want to use it, they must pay high patent fees. And at present, only some operators in the United States and South Korea have adopted the standard. "

At this point, Wu Tao has understood. Combined with the superficial understanding of the two standards in my memory, I crossed my hands and fingers, put them in front of me and said, "er... If I said that both standards should be done, Grandpa, won't you hit me?"

Although the vitality of GSM in the previous generation is very strong, the communication technology in the 3G and 4G era is still based on CDMA standards.

Qualcomm, an old patent hooligan, has severely searched the world by relying on the patent barriers set up early.

In that case, at present, we can only do both standards.

However, where did Gu Xueli want so much? As the general person in charge of the torch plan, his decision directly affects how big the stall will eventually be, how much money it will cost and how many results it will produce.

The bigger the stall, the heavier the responsibility.

Moreover, the choice of both standards is more like a golden mean and irresponsible decision.

So Gu Xueli was really angry, "you child, how can you stand and talk without backache? How can the money of the country be abused... "

Seeing that the old professor was about to start talking, Wu Tao decisively interrupted, "Grandpa, it's not too late to listen to me and make a decision."

"... first of all, the GSM standard has been one step ahead of the European market, and now it has occupied more than half of the country in terms of scale. And although GSM technology is somewhat backward, I estimate that it will have at least 8 to 10 years of vitality. In this way, it must be inappropriate for us not to introduce development. "

"... secondly, CDMA technology is very advanced and may be an inevitable development direction in the future. Therefore, if we don't do it now, we will still lag behind in the future. "

"... although both standards are adopted, the cost is too high; But with such a big market as China, we can reap the benefits. We might as well join the European 3GPP organization and start the domestic IC industry first. As for Qualcomm's CDMA technology, you can refer to the cooperation model of South Korea. "

"... in short, the GSM standard directly follows the path of industry university research transformation, while the CDMA standard, let's talk about it first. By the way, we can get some new patents on the basis of Qualcomm. After the real large-scale application in the future, it is also convenient to negotiate with Qualcomm. Patent replacement and sharing are not impossible. "

"... not really. It's a big deal to find a way to buy Qualcomm!"

Wu Tao talked freely. At first, Gu Xueli's eyebrows and eyes brightened, and then he was shocked.

After all, buying a foreign company sounds absolutely impossible at the moment. In particular, the other party is still a high-tech enterprise in the United States!

However, these words sounded bold, but they really provided Gu Xueli with the most feasible idea.

Even old Comrade Gu can see that this idea is essentially the same as Wu Tao's idea of engaging in the mobile phone industry.

Industrialization is carried out first, followed by technology accumulation and research, and finally achieve external strength and internal rigidity and complete autonomy.

After pondering, Gu Xueli wrote it down in his book. He took off his glasses and said, "our project team will organize an investigation in the United States and Europe in March next year. Why don't you go with us?"

"Good!" Wu Tao couldn't help but brighten his eyes. "But Grandpa, I'm still thinking about writing two more papers next year and looking for a professor from Tsinghua or Peking University to recommend me?"

Unexpectedly, Gu Xueli really blew his hair when he mentioned this, "why go to Tsinghua University and Peking University? Isn't Jinling University also very good? After the last report meeting, academician Cai wanted to recruit you... "

I didn't expect that the old professor had a strong collective sense of honor. For a time, Wu Tao also looked funny and speechless.

Fortunately, Yin Wenfang came over at the right time and brutally interrupted, "what's the matter, is there anything wrong with the child's desire to go to a better university? If I say, the child didn't consider JINDA, it's your JINDA that is not good enough! You know how to lose your temper with children. "

After talking, Gu Xueli stroked his knee and sighed. His old face was full of helplessness.

After all, it's not his fault that Jin DA can't compare with Tsinghua University and Peking University.

However, his tone softened when he was interrupted, "well, in fact, I am also qualified to recommend you to Tsinghua University and Peking University. I'll contact you later."

"That's great!" Wu Tao was overjoyed. "Grandpa, I'll inform you immediately after my paper is published. In this way, at least you have some confidence when you recommend it for me. "

"Hum! They dare not want you! Don't you, I guarantee you to go to Jinling University! " Gu Xueli clapped his chest with a bang.

Seeing Wu Tao's face, he wanted to laugh and didn't dare to laugh. After talking for a long time, he came back again
