Chapter 732: Keep the signal secret.
Chapter 732: Keep the signal secret.
The strong sense of pride from reporters and the public quickly cooled under questions from the United States representative. The perfect test results were forgotten just after the fatal problem of remote driving was mentioned. Now they have to calm down and see how the engineer of the Huge Industrial Monster will respond, and what did the car Shi Lei does when faced with such a serious problem.
No matter how powerful the Shi Lei car is, it is impossible for it to be connected to all the signal base stations throughout the city. If the base station is disconnected or the signal fluctuates, it is like a car running out of fuel, no matter how powerful this car is, it is unable to operate.
No wonder Time magazine and the United States Department of Commerce have consistently opposed Huge Industrial Monster's promotion of remote driving capabilities. Come to think of it, there really may be something wrong with the test right now.
"It's over. I was just too proud of myself and forgot about the network connection issue. The United States Rep is trying to break the pot and go all the way!"
"The United States representative checked the stability of the 4G network there and found there were two interruptions, but Shi Lei's car was unaffected at all. It seems that the United States representative really says there are secrets that cannot be revealed between Huge Industrial Monster and Testing Center..."
"If this is true, we will all face the world. You watch the broadcast live; there are not only domestic media but also dozens of foreign media."
"Although I also hope a miracle will happen, but our base station is not good. This person is thrown into the sky."
"Dead, dead, I didn't dare watch the lives below, and I'm so embarrassed I couldn't breathe."
"So embarrassed I couldn't breathe +1"
...
……
Countless viewers felt so embarrassed that they were about to explode, and the atmosphere in the test center was close to freezing. The paper in the hands of the United States representative was like a binding spell.
The change of scene made Jayne realize she had knocked on the right door, so she repeated what she had just said and glared at the ugly little old man she had just knocked out of her face.
Under his gaze, Master Craftsman stretched out his withered hands and asked indifferently: "So what?"
"Please explain, why Shi Lei car is unaffected by 4G network fluctuation?" Jayne was a little angry. This is a serious occasion, and Huge Industrial Monster has always emphasized the need for scientific evidence. Now that the evidence is out, they ignore it.
"Because our Shi Lei cars are unaffected by the 4G network in the first place," Master Craftsman glanced at her.
"What do you mean?"
"The meaning is very clear, you don't even understand the remote driving principle of Shi Lei car, what kind of third-party supervision agency are you?"
The senior tech next to Jayne suddenly retorted: "We all know China is in 4G network coverage, and it's not better than what we have in the United States, which has to do with the fact that China has the largest group of mobile network users in the world. We also admit that under the condition of a fluent 4G network, the Shi Lei car cannot establish an effective connection channel. However, you cannot guarantee the continuity of the 4G network. The network always cuts, and our test results proved it too."
"Your thinking is too limited." Master Craftsman looked like saying: "You're stupid."
"We are a third-party monitoring agency, and we only believe in professional knowledge." The technician sneered: "In the United States, we have also tried research on driverless technology. But for computers to recognize road conditions, we need to connect cars to the Internet and make complexes. The 4G network in the United States could not support the stability of the data stream at all. China's 4G network is not good either, you can't break this law."
"Really... do we have to...?"
One finger, shaking at Master Craftsman, was so angry the technician couldn't wait to rush up and kick the little old man hard.
"This is the question 1+1 equals 2. We all know there can be no other answer."
The technician gritted his teeth and insisted.
"Tell them," Ye Qing motioned for Master Craftsman to say a few words less, this guy is really infuriating when he hits people. But now is not the time to bicker, at a time when the media is watching.
"Director Duan, tell them for me." Master Craftsman sat back down, "I'm afraid he doesn't understand what I have to say."
"So I'll tell you something." Director Duan Shuang Qing happily said: "In fact, the network problem that everyone has been worrying about is precisely the problem that everyone should worry about the least."
Director Duan Shuang Qing's words made the media and the public watch the live broadcast again. Not only did they have a feeling of the sunshine from hell, but they had planned for it long before, and they were prepared to see the US representatives who claimed to be a third-party surveillance agency be embarrassed and thrown to the ground to the low world. After all, the Huge Industrial Monster represented China.
But why now... It makes no sense, and the Shi Lei car cannot control the signal base station.
"Well, it's as simple as it sounds, and it's as complicated as it is complicated." Director Duan Shuang Qing said a few words to the technician next to him in a low voice, and then continued: "In fact, we said before the test that the remote driving function should be done in the first place. The evaluation is technically feasible. It was just the Huge Industrial Monster hadn't finished building the relevant hardware at that time, so the transportation department rejected the plan on that, since it's technically feasible, is the 4G network connection is necessary? The answer is unnecessary, everyone understands it, the Huge Industrial Monster has understood it, and we also understand it. So the technical feasibility is naturally unrelated to the 4G network."
"So the Shi Lei car does not use the 4G network," the technician was shocked by thousands of waves! This enormous radius of action directly froze the brains of the journalists and the American representative. 'What can Shi Lei car use other than 4G network?'
"It's impossible," the United States representative immediately retorted: "the 4G network is the only possible solution. If we don't use it, can we use the satellite network? From ground to space, the Signal has to be relayed multiple times through ground base stations, which are more unstable and delayed than the 4G network, also more expensive."
"Of course not," Director Duan Shuang Qing laughed even more happily, his tone was full of smugness: "You never imagined. Everyone must know this; the Huge Industrial Monster's plan is to establish 5,000 energy service centers across the country."
"I know that land in the south of our company was acquired by the Huge Industrial Monster in just half a month, the main building of the energy service center was built and I heard it would be officially inaugurated in a week," in the media booth, a reporter rushed to speak.
"It's true ~ the Huge Industrial Monster has established an independent wireless network," Director Duan Shuang Qing's voice dropped, and an electronic map of Shanghai suddenly appeared on the big side screen.
On the map, two large green dots flashed in the new area of Pudong and Songjiang respectively. In another area, there was a small red dot that flashed constantly. According to the map information, that was the location of the testing center where they were.
"The two green dots are the energy service center built by the Huge Industrial Monster in Shanghai. The red dot is the Shi Lei car in front of us."
"It can't be..." The United States technician was going refuting again and before he could say anything, he was suppressed by director Duan Shuang Qing.
"I know that the United States representative will definitely request that the distance between the two be less than 20 kilometers. There is no way a wireless network signal could transmit such a long distance. Look at the map."
Suddenly there were more than tens of thousands of little red dots. These little dots are everywhere in the city of Shanghai, and their locations are irregular.
"Do you understand?" Master Craftsman shook his head at the United States Rep.
"You mean, these tens of thousands of points are all small base stations built by Huge Industrial Monster?" The United States representative's face instantly turned extremely ugly: "It's...it's...Impossible, we investigated and found the Huge Industrial Monster did not execute this kind of base station investment plan."
"We really don't have an investment plan for base stations, nor do we plan to invest in establishing base stations. So it's not tens of thousands of small base stations, but tens of thousands of Shi Lei cars."
This time, Ye Qing stood up, staring at the media booth with surprised eyes, and said:
"It is the secret weapon of our Huge Industrial Monster, based on the remote driving function. The energy service center is the neural node of the remote driving network. In the near future, it will be located in all cities in the country. And each car is a cell on the nerve of the network. Without any modification, it directly uses the wireless network module of the car itself for a short-distance connection to form an invisible network; allowing each Shi Lei car to be connected with the remote driving function activated and can drive without a worry in this network."
Ye Qing's indifferent voice struck the ears of hundreds of reporters at the scene, no less than thunder!
I see!
I see!
The energy service center is a data processing node of the whole network, and the Shi Lei cars in every corner of the city are transit platforms. How long has the Shi Lei car been on the market? There are now tens of thousands of vehicles here in Shanghai.
"God, is it really possible?"
The reporters were shocked by the news to the point that their minds went blank, and they were also very laughable at the conservative and stubborn ideas before.
Talking about the unreliability of the 4G network for half a month, he he ~ As a result, the Huge Industrial Monster did not plan to connect the hundreds of millions of users across the country to the 4G network, and it built theirs.
"The energy service center's 2.4GHz high-speed channel base station can cover a radius of 50 kilometers. The networking distance of each Shi Lei car depends on the terrain and the networking distance and is an average of three to five kilometers, naturally in the eyes of the United States representative. This is an impossible technology. Because the existing 2.4 GHz frequency band is an international common open frequency band, it has the characteristics of a high frequency and high transmission efficiency, but the electromagnetic wave decays quickly, so it cannot extend the distance to the range of 50 kilometers."
"But we can do this by using beam forming technology to achieve longer transmission distance with more advanced communication chips. In the connection just now, this car Shi Lei did not relay the signals to other cars, because the distance was too close to being unused, while driving remotely, the function has yet been unopened to the public, and we cannot do it without users' consent."
"When this function is opened, every network user can enjoy the energy service center charging subsidy. I said that; you understand?"
