"Brother Six, are you up?"
It was Li Yun's voice.
Li Min was disturbed and was very unhappy.
If it were before, he could allow Li Yun to come to him if something happened.
But now he also has a wife, and Li Yun is also the eldest son. How could he be so reckless? Don’t you know that this is the most comfortable time to sleep?
Moreover, Semaga's voice came from outside the door.
She shouted softly:
"Brother Six! Are you up?"
It seems like the couple did this on purpose?
He opened his eyes, and it was still dark outside. It's not even bright yet!
I looked at the clock on the wall again. It was half past five. Good guy, are you here so early?
Ji Ruxue lay on the side and asked, "Ms. sir, what's wrong? What are the seventh brother and sister-in-law doing? So early!"
She is a light sleeper, so she wakes up earlier.
The other four girls were still asleep. During this period, everyone was very busy.
So sleep is also deeper. Under normal circumstances, it is impossible to wake them up.
Moreover, they did not go back to their own rooms to sleep, they always came to sleep at Li Min's place.
Li Min had no choice but to have a large quilt specially made for the five people to sleep on the same quilt as him.
It's strange to say that six people sleep together without even turning on the heater.
It was like there was a fire under the quilt, fighting against the cold.
Only Ji Ruxue was awake.
Li Min said softly:
"This morning I said we were going to see some kind of phone test!"
"It's still dark now, what's wrong with him? He's so anxious!"
"I don't know either. This kid has been impatient since he was a child! I don't know who he learned this impatience from!"
Li Min woke up and stood up.
I'm afraid I won't be able to sleep now.
Ji Ruxue wanted to get up with him.
"Ms. sir, can I come with you?"
But he stopped him.
"You go on sleeping. You can still sleep for two more hours. I'll go out and take a look first! I'm calling you for something!"
"But my husband..."
"Okay, go to sleep, I can't sleep anymore! It's time to get up and take a breath of fresh air."
Ji Ruxue yawned, her yawn had betrayed her. I was so sleepy last night!
"Okay! Then I'll sleep a little longer! If necessary, you really have to call me!"
Li Min ignored her and stood up, put on his clothes and walked out the door.
At this time, Li Yun and his wife were knocking on the door.
Li Min opened the door.
Walked out.
Li Min looked at Li Yun and Sema with a straight face.
Then close the door first.
"What are you doing? What time are you here to wake me up?"
Anyone would be angry in this situation.
Li Yun didn't speak, but Semaga said in not very fluent Chinese: "Sixth brother, don't blame your husband, I asked him to come with me!"
Li Min looked at Semakar, maybe she thought he wouldn't scold her.
Li Min really couldn't do it when he scolded women.
He finally sighed and said, "Okay, I don't blame you anymore. Tell me, what's the matter?"
Li Yun said: "Brother Six! I thought of a direction, so I wanted to come over and discuss it with you! This direction is very important!"
Li Min said: "Can't we discuss it later? It has to be now?"
"Don't we have to do the acceptance check later? And I'm afraid I'll be so busy that I forget! So, I brought Semaga over here to discuss it with you!"
Li Min was angry and wanted to laugh. If you’re afraid of forgetting, just write it down!
This kid is really one-dimensional.
Now that he was awake, he didn't say anything more.
"Okay then, tell me what you thought of?"
The three of them walked towards the office.
Li Yun said as he walked: "Brother Six, the way we thought of arranging base stations in a square shape seemed to not be able to provide complete coverage and there would be blind spots. Until last night, I ate a honeycomb and suddenly thought, why not imitate a honeycomb? How about arranging base stations in different shapes?”
When he finished speaking, Li Min stopped immediately.
Because Li Min talked about this thing, it will be called cellular network in the future.
It is named because the signal coverage of each communication base station that forms the network coverage is hexagonal, making the entire network resemble a honeycomb.
The reason why cellular networks are widely used is due to a mathematical conclusion, that is, when a circle with the same radius covers a plane, when the center of the circle is at the center of each regular hexagon of a regular hexagonal grid, that is, when the center of the circle is at the center of a regular triangular grid The smallest number of circles used when making points.
Although the graph with the smallest number of nodes can cover the largest area, even if the nodes are required to be on a grid with translation characteristics like a crystal lattice, it is still an unknown problem to be solved.
However, in communications, it is often reasonable to use circles to express practical requirements, so in order to save the cost of building equipment, the regular triangular grid, or also called the simple hexagonal grid, is the best choice. The network formed in this way is covered together and shaped very much like a honeycomb, so it is called a cellular network.
I didn't expect Li Yun to think of this. This is really strong.
This is a mathematical question.
I really didn’t expect to be thought of by Li Yun.
It's no wonder that Li Yun can lead the entire technology department.
"Brother Six, what's wrong? Am I right?"
Li Yun asked a little worriedly.
He was afraid that Li Min would say he was wrong.
He didn't want to, but Li Min said: "Very good! You are right! This can indeed cover everything. This idea is indeed very good!"
"I'm just telling you, Sema, if you still don't believe it, Sixth Brother will be very happy when he hears what I say!" Li Yun was as happy as a child.
Semaga just smiled.
Act like it would be fine as long as he is happy.
"but!"
Li Min changed the subject.
Li Yun seemed to feel something was wrong.
"But what? Brother Six, tell me!"
"Don't wake me up so early in the future. I didn't fall asleep until early in the morning yesterday! Do you understand?"
"Yes, yes! Brother Six, I understand!"
Li Yun was a little embarrassed.
So that’s said and done, what’s next?
Li Min asked: "I agree with your plan. So, how will you arrange the next time?"
"Brother Six, since you're up, why don't you go through today's arrangements with me?"
Li Min said: "No, you can do this by yourself, I believe in you! I only want the results, the process, etc., you don't have to tell me!"
"Ah, so..."
Li Yun was a little disappointed, but Semaga said: "Ms. sir, this is the opportunity given to you by Brother Six to independently support the entire acceptance. You must do it well!"
"Semaga, you are right!"
The two actually started to encourage each other.
This made Li Min a little depressed. Was he redundant?
"When it comes time for acceptance, you let me go again! Do you understand?"
"Yes! Sixth Brother!"
Finally, he quickened his pace and headed towards his office.
As for Li Yun and Semaga, they were still there encouraging each other.
