As a new academician of the Chinese Academy of Engineering, Gu Xueli is the general person in charge of the National Torch Program - Mobile Communication Project.

Wu Tao came to ask him about this, which was naturally very appropriate.

However, as soon as Gu Xueli heard this, his face immediately turned pale: "Do you think that these basic technologies are farmer's farming? Sow seeds in the spring, and you can harvest them in the fall?"

Wu Tao was not annoyed, after all, as a junior, he knew Lao Gu's temper.

Besides, Lao Gu is so vigilant, and Bacheng is also in the previous mobile phone prototype design cooperation, and he was too anxious.

So he smiled and said: "Grandpa, as the saying goes, if you plant melons, you will get melons, and if you plant beans, you will get beans." Even if we don't have it now, when will we have it, we have to have a rough promise, right?"

At this time, Yin Wenfang brought over with a fruit plate, and when he saw his wife blowing his beard and staring at the ground again, he couldn't help but hug Wu Tao and said, "It's rare for a child to ask you something, can't you talk about it well?"

"Go and go, you old woman, you don't understand anything, don't interject!" It seems that Comrade Lao Gu has become an academician, and his temper is also a little rising. I would never have dared to do this before.

What is rare is that Yin Wenfang listened to it, but she was not annoyed. just patted Wu Tao on the shoulder and said comfortingly: "Tao, don't worry about him, he has such a bullish temper." ”

When Yin Wenfang left, Gu Xueli muttered: "Now this torch plan is facing two major problems. First, the country's IC industry has no foundation, and the comprehensive layout requires planning and time; second, when the expert group chooses which way to go, there is a disagreement, GSM and CDMA, how to choose?"

Listening to these two words, Wu Tao felt familiar and strange at the same time.

GSM is a technology in the 2G era, which has been prevalent until nearly a decade later, but CDMA should be a 3G technology in the impression. How can it be compared?

Without hesitation, he asked, "What is the difference between GSM and CDMA?"

Gu Xueli's thin palm was placed on his knee, "Technically speaking, CDMA is more mature and advanced. It came from the hands of Qualcomm in the United States, converted from the military, and used sub-code multiplexing technology. ”

“...... GSM is a time-sharing multiplexing technology, a standard developed by the Europeans, relying on the advantage of early implementation, and now it is the most widely used. ”

“...... Technically speaking, CDMA has more than 10 times the user capacity of GSM, and the signal is clearer and less likely to be eavesdropped. ”

“...... However, Qualcomm has registered a large number of patents in the CDMA standard, and other countries and organizations must pay high patent fees if they want to use them. At present, only some operators in the United States and South Korea have adopted this standard. ”

Speaking of this, Wu Tao has already understood. Combined with the understanding of these two standards in his memory, he crossed his hands and put his fingers together in front of him and said, "Uh...... If I say that I want to do both standards, you won't beat me, grandpa, right?"

Although the vitality of GSM was strong in the previous life, the communication technology in the final 3G and 4G era is still based on the CDMA standard.

Qualcomm, an old patent rogue, relied on the patent barriers set up early to ruthlessly loot a sum of money all over the world.

In this case, at present, it seems that only two standards can be pursued.

However, where did Gu Xueli want to get so much, as the general person in charge of the Torch Project, his decision-making directly affected how big this stall would be in the end, how much money it would cost, and how much results it would produce.

And the bigger the stall, the heavier the responsibility.

What's more, the choice to engage in both standards is more like a middle-of-the-road and irresponsible decision.

So Gu Xueli was really a little moved, "You kid, how can you stand and talk without a backache? How can the country's money be wasted casually......

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

“...... First of all, the GSM standard was marketed by the Europeans, and now it has occupied most of the country in terms of scale. And although GSM technology is a bit backward, I estimate that it will have at least 8 to 10 years of vitality. In this way, it is definitely inappropriate for us not to introduce development. ”

“...... Secondly, the technology of CDMA is very advanced, and it is likely to be an unavoidable development direction in the future. Therefore, if we don't do it now, we will still lag behind in the future. ”

“...... Although the cost of both standards is too high, we can sit on such a large market in China and reap the benefits of fishermen. The 3GPP organization of the Europeans, we might as well join and start the domestic IC industry first. As for Qualcomm's CDMA technology, you can refer to South Korea's cooperation model. ”

“...... In short, the GSM standard directly takes the road of industry-university-research transformation, and the CDMA standard, let's talk about it first, by the way, on the basis of Qualcomm to make some new patents, after the real large-scale application in the future, it is also convenient to negotiate with Qualcomm. Patent replacement and sharing are not impossible. ”

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

Wu Tao talked eloquently, and Gu Xueli's eyebrows and eyes gradually brightened at first, until his heart beat later.

After all, buying a foreign company sounds absolutely fantastical at the moment. Especially since the other party is still a high-tech company in the United States!

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

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

Industrialization is first rolled out, and then accompanied by technology accumulation and research, and finally it is strong on the outside and strong on the inside, completely independent.

After pondering for a while, Gu Xueli wrote it down in his notebook. He took off his glasses and said, "Our project team will organize an investigation and investigation in the United States and Europe in March after the next year, will you go with you?"

"Okay!" Wu Tao's eyes couldn't help but light up, "But grandpa, I'm still thinking about writing two more papers next year, and find a professor from Tsinghua University or Peking University to recommend me for special recruitment?"

Unexpectedly, when he mentioned this, Gu Xueli really blew up, "Why do you want to go to Tsinghua University and Peking University? Isn't Jinling University also good? After the last report meeting, Academician Cai wanted to recruit you......

I really didn't expect the old professor's collective sense of honor to be quite strong, and Wu Tao was also funny and speechless for a while.

Fortunately, Yin Wenfang came over at the right time and interrupted arrogantly: "The child wants to go to a better university, what's wrong, is there anything wrong? If you want me to say, the child didn't think about Jinda, it's because you Jinda is not good enough! You are good, you know that you have a temper tantrum with the child." ”

After that, Gu Xueli sighed on his knees, and his old face was full of helplessness.

After all, Jin Da is not as good as Tsinghua University and Peking University, and it is not his fault alone.

However, he was interrupted like this, and his tone softened, "Okay, in fact, I am also qualified to recommend you to Tsinghua University and Peking University now, and I will contact you when I go back." ”

"That's really great!" Wu Tao couldn't help but be overjoyed, "Grandpa, I'll notify you as soon as my paper is published." In this way, at least when you help me recommend, I have some confidence. ”

"Hmph, they dare not want you! I don't want you, I will guarantee you to go to Jinling University!" Gu Xueli patted his chest.

Seeing that Wu Tao's face twitched, he didn't dare to laugh if he wanted to laugh, but after talking for a long time, he came back again......
