"Mr. Carl Vinson, does Motorola still have any objection to the technical specification that 'the sum of the transmitted power of the mobile phone signal and the transmitted power of the base station received at the location should be equal to minus 73dB'?

In our opinion, based on the above discussion, this value should be the optimal value to ensure that various wireless signal transmitting devices do not interfere with each other in the future. Even if your mobile phone has to limit the transmission power and increase the signal blind zone, I don't think there is anything you can do.

If you have to ensure the coverage of the call signal, you can increase the density of the cell base station and shorten the side length of the cellular hexagon. I believe that your company has not yet started the construction of the base station network, and the cost of modifying the project plan should be acceptable. ”

At the IEC Electromagnetic Compatibility Society in the afternoon, Gu Biao personally led Professor Erickson and other Stanford bricks to talk about it vertically and horizontally, and launched a new wave of attacks on Motorola.

The key is that Gu Biao's rhetoric is still very reasonable and well-founded, and he is "working for the benefit of the later entrants in the industry".

That posture and aura are no weaker than Cai's shouting for "fighting for the personality of 40,000 people".

"That's ...... We accept it in principle. Carl Vinson, CTO of Motorola, was a little cramped, but the debate had already been fought for several rounds, and he had to accept what he could say.

No way, Gu Xiao's fan power was so strong that the other Americans at the meeting forgot that Gu Qiu was Chinese and Motorola's Galvin family was American.

Everyone realized that "allowing Motorola, which is one step ahead, to arbitrarily amplify the transmission power of mobile phones in certain situations will not only harm the personal health of consumers, but also lead to suppression and interference with the machines of peers who want to enter this industry in the future." ”

Of course, everyone only needs to know about the suppression and interference of peers, and there is no need to say it verbally, let alone tell consumers.

If you need to warn consumers on the table, you only need to say that "excessive radiation is harmful to health" is enough.

Everyone is an old fox in the business circle, and the basic skills of talking about people and talking nonsense don't need to be taught.

After Gu Biao took a point, he continued to talk eloquently: "Okay, then let's start the discussion of the next clause: in view of the product standard agreed in the previous article, I think it is necessary to prevent cellular mobile phones from increasing the transmission power of the local machine without restrictions in an environment with extremely poor signals to achieve channel quality balance."

According to the results of the 1314-C test experiment and the results of Professor Erickson on pages 28~33 of the November issue of IEEE-***'82, I think it is more appropriate to set this critical value at minus 109dB, that is, when the ambient signal is lower than minus 109dB, the mobile phone should actively reduce the call quality or prefer to disconnect, rather than seek to maintain stability with high transmit power.

Of course, we should encourage enterprises to improve the technology in the sensitivity of the processing circuit, because the performance improved by improving the sensitivity of the processing circuit will not cause redundant interference to the outside world......"

Motorola's technical negotiators are already sweating on their foreheads.

Representatives of some other companies have also gradually become solemn. Although their interests have not been harmed, it is not a good thing to see a Chinese person with such a far-reaching mind.

Some people may wonder how Gu Biao knows so much. But in fact, this thing is the most superficial peripheral common sense requirements of the wireless communication industry in later generations, and it is slightly deeper than the "Electromagnetic Compatibility" of the first major in electrical research in later generations.

As for those in communication engineering, it is possible to use it for internship in the fourth year of undergraduate.

In his previous life, Gu Biao engaged in technology on such an awesome platform as Ahri, and there were always some communication dogs who jumped from units such as Xia Wei and Xiaomi. (The communication dog has no meaning of humiliation, it is self-deprecation, and the programmer can also call the code dog, because he is tired of being a dog.) ）

That's the benefit of working in technology at a top big company, where you can get access to a lot of high-level talent – although if you don't cross it, that common sense will be a talking point and you won't be able to monetize it.

Therefore, at this moment, Gu Biao casually took out some of the points that the international industry standards in later generations had been tested and condensed by history, and made it difficult for Motorola, which was enough to make the other party unconscious, awe-inspiring, and then dare not despise it.

……

Afternoon recess.

Motorola's junior Chris Galvin brought together CTO Carl Vinson and other technical executives involved in the negotiations.

"Carl, that Gu Biao, and his subordinate Professor Erickson, seem to know more than you expected, and you are underestimated!" Chris pointed out unceremoniously.

Carl Vinson admits decadently: "I'm sorry, when we were preparing, we really didn't expect Gu Biao to be so clear about electromagnetic compatibility and interference in wireless communications, and I thought they had only conducted limited research based on the problems exposed by the previous Falklands war."

Now it seems that he envisioned far more extreme situations and complex environments than human history has actually experienced. I couldn't understand how his brain could simulate and deduce things that had never happened in human history and were destined to happen when wireless communications flourished and interaction was extremely stressful.

It's like a Laplace demon all the time, as long as you know the initial state of every atom in the world, you can deduce the future by calculation!"

"Determinism is long dead! That's the remnants of the 19th century! The world now believes in quantum inaccuracy, God rolls dice, chaos theory! Put away your Laplace demon! No one can predict the future with precision!" Chris Galvin rebuked as angrily as the Führer took off his glasses.

His upbringing did not allow him to listen to Carl Vinson's excuses of shirking responsibility.

A certain deputy technical director on the side, afraid that they would quarrel, hurriedly changed the topic and mediated: "Then what should we do now?" Mr. Galvin, you can get an idea first, and we will do our best. I think the key is not to let Gu Biao disrupt the situation too much and imagine so many technical risks that have not yet happened.

Otherwise, if we delay our mobile phone R&D and production plan, the loss will be big - the board of directors has made it clear that the most important thing in a few years is to produce and put mobile phones on the market, and start the actual construction of base station networking. ”

Chris Galvin slapped the table: "Of course I know! This is a decision made by my father, will I not know!"

Deputy Director of Long Tao: "Then why don't you contact Gu Biao in private and see what conditions are there for him to shut up?" Now that he is the home field, this meeting was brought to China by him pretending to be weak, and we can't use it through the organizing committee. Besides, Sony's Akio Morita has been staring at us, and he wants to catch our mistakes, but he can't be reckless. ”

Chris Galvin thought about it, and the people sent by the company to participate in the academic conference this time were all technical officials.

He himself did not come to the meeting, but to build relations with the Chinese high-level and to "make Hujiang the first city in China to promote wireless paging station business".

He did meet with the local mayor, and even the minister of the Ministry of Electronics Industry in Huaxia, and other high-ranking officials, and brushed his face.

This is the main purpose of his personal condescension to China as a young director.

But now it seems that the mediation of the academic conference also requires him to communicate with Gu Biao again.

For Motorola, the first priority this year is that the mobile phone must be put into production, and all technical quality supervision must be broken, which is the most important.

Other benefits can be weighed and discarded in comparison.

Gu Biao's house, using "describing the technical risks of mobile phones to the people", has already reaped a lot of benefits from Motorola, and Chris Galvin has been very polite to hold him before.

But it seems that the appetite is too big, and the meat will be cut at the end.

……

For dinner, the cocktail banquet hall of the Zhaolong Hotel.

Tonight's dinner is a buffet and cocktail reception.

Gu Biao smiled like a spring breeze on the face of the host, hugged his genuine girlfriend in a gorgeous dress, mediated between a group of foreign businessmen, and frequently nodded and toasted.

Han Ting was also wearing a gorgeous dress, shuttling through the crowd nobly and elegantly, but she represented Hanle Electronics, and she kept a good distance from Gu Biao in public. At the age of 35, although she can't compete with her young beauty, she is still a very mature and intellectual attitude among successful beautiful businessmen.

Chris Galvin saw the opportunity and stopped Gu Biao with champagne.

"Gu, I toast you, your girlfriend is really dressed up tonight, and she is glamorous. Chris complimented in an American way.

Gu Xiao smiled slightly: "Thank you, but we Chinese, generally do not praise other people's girlfriends for being the most beautiful in the audience, we are more reserved, and we don't think that it is an honor for our girlfriends to be targeted by too many people." ”

Chris was slightly embarrassed, and the sycophants were not filmed well, but he still had to continue to force himself to the point: "Gu, I think what you said above is very reasonable, but don't you think it's too fanciful? Those extreme accidents are indeed very tightly deduced, but after all, they have never happened."

No matter how you deduce, in the end it will definitely be a leak, it is better to try commercial use in a small area, let the mobile phone business pilot, and then the problems exposed will definitely be much more than you imagined, and it is much more comprehensive. ”

In and out of the words, they all hope that Gu Biao will "successfully conclude" this conference first, so that Motorola can "discuss mature technical standards in the industry and put them into production", and talk about the rest slowly.

"You're right, it's really better to find extreme cases of compatibility issues than to actually use it commercially and stress test it in the field. Gu Biao elegantly agreed with the other party's statement.

Chris Yixi: "Then you agree ......"
