Chapter 120 Base Station Site Selection Optimization, China Unicom Pays Strong Attention (2) (Subscription Request)
Zhou Wei's action made Feng Guotao a little confused.
"Why do you need all the data from the base station? Haven't you finished your project? What's wrong? Is there a problem?"
Feng Guotao's heart also skipped a beat.
The construction cost of a base station is 80.
China Unicom Shanghai Head Office has built a total of 700 base stations according to the research and design of the base station layout by Zhou Wei's team.
If Zhou Wei made a mistake in calculation, the loss for each base station would be an additional 80 yuan.
However, Feng Guotao felt that the probability of such a thing happening was still too small.
China Unicom is not a fool to simply believe the words of Feng Guotao's team.
After Feng Guoteng's team optimized the base station layout, China Unicom submitted the plan to the company's internal engineering department fund for review.
After reviewing the plan, the Engineering Department also agreed to it.
Reviewing the layout of a base station is definitely easier than doing the layout of a base station.
The accuracy of the review is still guaranteed.
Zhou Wei was too lazy to explain to Feng Guotao.
This kind of thing cannot be explained in a few words.
Zhou Wei's team originally had cooperation with China Unicom and had also worked on projects in Jiangsong District.
So there is nothing to hide about these data.
Feng Guotao provided the data according to the list provided by Zhou Wei.
The team immediately began reviewing.
October 10th is the last day of National Day.
Tourists in Shanghai have returned to their hometowns and prepared to start work.
And in the large conference room on the 3rd floor of China Unicom headquarters in SJ District.
Zhou Wei slumped in the chair, feeling that all the strength in his body had been drained away.
After almost 7 days of repeated verification.
Zhou Wei was able to confirm that Lu Shan's model was accurate.
More accurate than anything his team had used in the past, and much faster.
In the past, they spent almost half a year doing research, making models, doing analysis, and finally making the layout.
It took a lot of effort to figure out the layout of the base stations.
However, Lu Shan's model software only requires inputting the corresponding parameters and can produce results within half an hour, and it is much more accurate than theirs.
The number of communication base stations that can meet the 3G full coverage requirements for all users in Jiangsong District is not 700, but 567.
80% of the layout is the same, but 20% of the positions will be adjusted.
If China Unicom follows the layout calculated by Lushan Software, it will save an additional 100 million yuan while ensuring existing communications.
During these 7 days, Feng Guotao also assisted Zhou Wei in his work.
He knew about this matter more or less.
Seeing Zhou Wei slumped in his seat with lifeless eyes, Feng Guotao's heart skipped a beat and he had a bad feeling.
"How is Professor Zhou?"
Feng Guotao handed a cigarette to Zhou Wei.
Zhou Wei also smokes sometimes, but he only smokes at certain times, places and occasions.
He won't smoke in the conference room, nor will he smoke in crowded places.
But today he was indeed in a bad mood and his mind was a mess.
After taking the cigarette, he took a deep breath and calmed down.
What matters in scientific research is seeking truth from facts.
If mistakes and responsibilities occur, we must also have the courage to take responsibility.
What's more, if Lu Shan hadn't come up with a new model, Zhou Wei and China Unicom might not have known about this mistake for 10, 20 or 30 years.
As for the responsibility, Zhou Wei has no responsibility, because he calculated completely according to the mature old model, and his results would not be much different from those of other teams, and were approved by China Unicom's engineering department.
But as a professor of communications engineering and an expert in the 3G field.
I can't get over the hurdle in my heart.
After blowing out a smoke ring, Zhou Wei said with a helpless smile: "We use the new model and new software to calculate that if Songjiang deploys 567 base stations according to the model, its communication and network effects will be better than if we deploy 700 base stations."
Feng Guotao was shocked by this.
If there is a discrepancy of one or two or even ten or so, that is understandable.
However, the design of more than 100 base stations costs almost million yuan.
This is too exaggerated.
"Professor Zhou, are you under too much pressure? You made a mistake in your calculations."
“How is it possible to enter and exit more than 100 base stations?”
"Our Songjiang 3G network full coverage project has been highly recognized by China Unicom and was awarded the gold medal for the project." "In addition, we have also been highly recognized by relevant national departments, and many media have come to interview and report on it."
"It's impossible that the difference is so big!"
Zhou Wei also felt that his words were not enough, mainly because he did not have the energy to explain.
He handed Feng Guotao the analysis report that the team had written in the past few days: "Engineer Feng, please take a look at it."
"I think we should report this matter to the head office."
"Songjiang is a demonstration area, but 3G is being rolled out across the country."
“If we follow the new model, we will save a lot of money and achieve much better results than we do now, and we will also save on labor costs.”
"I've been bored in the conference room for several days. You read the analysis report first. I'm going to go out for a walk to relax."
Feng Guotao's attention is now entirely on the analysis report.
The analysis report is very complete and supported by data.
Feng Guotao was very shocked after seeing it.
He immediately called all of his engineering team members, and they carefully studied the analysis report and analyzed it all again.
After taking a walk outside, Zhou Wei, Teacher Gao and others went to eat a little and then returned to the hotel to have a good rest.
I also took the time to book a flight back to Jiangzhou tomorrow.
It was five or six hours later before they returned to the conference room.
It was found that more than a dozen engineers from China Unicom were checking each report with computers and analysis reports.
When Zhou Wei saw this scene, he went outside to smoke another cigarette.
Then he heard someone in the conference room shouting, "The analysis results are out!"
After putting out the cigarette, Zhou Wei walked into the meeting room.
Everyone gathered around Feng Guotao.
In Feng Guotao's hand was the data analyzed by China Unicom engineers.
"It is indeed 567 seats, and the layout is more reasonable as stated in the analysis report. Our 700-seat layout still has many flaws."
“But it’s strange that I can’t analyze it without the old-fashioned model.”
Zhou Wei smiled and said, "Old Feng, the result is correct, right? We worked on it for seven days, and the data we got is exactly the same as the data this software got in half an hour."
Feng Guotao was completely unable to hold back.
"Does that mean we spent an extra 100 million in Songjiang?"
"How can I explain this to the head office?"
Zhou Wei said: "To be honest, the new model is indeed much more advanced than our old-fashioned method."
Feng Guotao quickly asked, "Professor Zhou, is this the new model your team has developed? It can be used in the layout of 3G base stations in other cities. You are right. We need to report this to the head office immediately."
Zhou Wei smiled bitterly and said, "This was not made by our team. This was made by a freshman. I didn't quite believe it, so I came here to review it. The result proved that this student was right."
