The first rebel of the Tang Dynasty

Chapter 1183 Advanced Cellular Network

"Brother Six, are you up?"

It was Li Yun's voice.

Li Yin was very upset when he was quarreled.

If it was before, he could allow Li Yun to come to him if he had something to do.

But now he also has a wife and family, Li Yun is also the eldest, how can he be so reckless?Don't you know that this time is the most comfortable time to sleep?

And Semaga's voice came from outside the door.

She cried softly:

"Brother Six! Are you up yet?"

It seems that the couple did this on purpose?

He opened his eyes, but it was still dark outside.It's not even daylight!
I looked at the wall clock on the wall again, 05:30, boy, are you here so early?

Ji Ruxue lay on the side and asked, "Sir, what's the matter? What are the seventh brother and sister-in-law doing? It's so early!"

She is a light sleeper, so she wakes up earlier.

The other four girls are still sleeping soundly. During this time, everyone has been very busy.

So the sleep is also deeper.In general, it is impossible to wake them up.

And they didn't go back to their own room to sleep, they would come to sleep with Li Yin no matter what.

Li Yin had no choice but to ask someone to make a special big quilt, and let five people sleep under the same quilt with him.

Strange to say, the six of them slept together without even turning on the heater.

There is a fire in the bed, against the cold.

Only Ji Ruxue was awake.

Li Yin said softly:

"I said this morning that I wanted to see some kind of phone test!"

"It's still dark now, what is he doing? So anxious!"

"I don't know either, this kid has been impatient since he was a child! I don't know who this impatient person learned from!"

Li Yin woke up and stood up.

I'm afraid I won't be able to sleep.

Ji Ruxue wanted to get up with him.

"Sir, can I come with you?"

But it was stopped by him.

"Go on to sleep, you can sleep for two more hours, I'll go out and have a look first! I'm calling you for something!"

"But my husband..."

"Okay, go to sleep, I can't sleep either! Just get up and get some fresh air."

Ji Ruxue yawned, and her yawn had already betrayed her.Last night was too sleepy!
"Okay! Then I'll sleep for a while! If you need it, you can really call me!"

Li Yin didn't pay attention to her anymore, but got up, put on his clothes, and walked outside the door.

At this time, Li Yun and his wife were about to knock on the door.

Li Yin opened the door.

Came out.

Li Yun looked at Li Yun Semaga with a straight face.

Then close the door first.

"What are you doing? What time is it, and you wake me up?"

In this case, anyone will be angry.

Li Yun didn't speak, but Saimaga said in not-so-fluent Chinese: "Sixth Brother, don't blame Mr. Xianggong, I asked him to come with me!"

Li Yin looked at Semaga, probably because she felt that she would not scold her.

Li Yin really can't do anything about scolding women.

He finally sighed and said: "Okay, I don't blame you guys anymore, tell me, what's the matter?"

Li Yun said: "Sixth brother! I thought of a direction, so I wanted to come and discuss with you! This direction is very important!"

Li Yin said: "Can't we discuss it later? Must it be now?"

"Isn't there going to be an inspection later? Then I'm afraid that I'll be so busy that I'll forget it! So, I'll bring Semaga over to discuss it with you!"

Li Yin was angry and wanted to laugh.Afraid of forgetting, just write it down!

This kid is really a muscle.

Now that he had woken up, he didn't say anything more.

"Well, tell me, what did you think of?"

The three walked towards the office.

Li Yun said while walking: "Sixth brother, we thought of the way of arranging base stations in a square, it seems that it can't be completely covered, and there will be dead spots. Until last night, I ate the honeycomb, and suddenly thought, why not imitate the honeycomb What about the shape of the base station?"

When he finished speaking, Li Yin stopped immediately.

Because Li Yin mentioned this thing, it will be called cellular network in the future.

It is named because the signal coverage of each communication base station that constitutes the network coverage is hexagonal, so that the entire network looks like a honeycomb.

The reason why the cellular network is widely used is derived from a mathematical conclusion, that is, a circle with the same radius covers the plane. Use the least number of circles when pointing.

Although the graph that can cover the largest area with the least number of nodes is still an unknown problem to be solved even if the nodes are required to be on a grid with translational properties like a lattice.

But in communication, it is usually reasonable to use circles to express practical requirements, so in consideration of saving equipment construction costs, regular triangular grids or also known as simple hexagonal grids are 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.

Unexpectedly, Li Yun thought of this, which is really strong.

This is a math problem.

I really didn't expect to be thought of by Li Yun.

It's no wonder that Li Yun can guide the entire technology department.

"Sixth brother, what's the matter? Am I wrong?"

Li Yun asked a little worried.

I was afraid that Li Yin would say that he was wrong.

Not thinking about it, but Li Yin said: "Very good! You are right! This way can really cover everything. This idea is really good!"

"I'll just say it, Semaga, if you still don't believe it, Sixth Brother will be very happy to hear me say that!" Li Yun was as happy as a child.

Semaga just smiled.

Act like it's fine as long as he's happy.

"but!"

Li Yin changed the subject.

Li Yun seemed to feel bad.

"But what? Sixth brother, 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 know?"

"Yes yes yes! Sixth brother, I know!"

Li Yun felt a little embarrassed.

So with that being said, what do we do next?
Li Yin asked: "I agree with your plan, so how will you arrange the next time?"

"Sixth brother, since you are already up, why don't you live with me for today's arrangement?"

Li Yin said: "No, you can do it yourself, I believe in you! I just want the result, you don't have to tell me about the process!"

"Ah, so..."

Li Yun was a little disappointed, but Semaga said: "Sanggong, this is the opportunity given to you by the sixth brother to let you independently support the entire inspection, you must do it well!"

"Semaga, you are right!"

The two actually started to encourage each other.

This made Li Yin a little depressed, was he redundant?
"When it's time for acceptance, you let me go! Do you understand?"

"Yes! Brother Six!"

Finally, he quickened his pace and headed for his office.

As for Li Yun and Semaga, they were still there to encourage each other.
