Siheyuan: The soul travels through time and space to change fate

"Da Mao, now that you're back this time, you don't have to leave for the time being, right?"

Lou Xiao'e was also very happy when she saw Xu Damao.

She also didn't expect that Xu Damao would come back suddenly.

"I won't leave. I'll just go there for a month or two to check on the progress. I won't have to stay there for a long time."

Xu Damao's next job basically requires completing the construction of the Sijiu City.

Even if India was causing trouble, he wouldn't need to show up as Bang Geng was watching.

It is true that there is no need for long-term business trips for the time being.

As for the future, it’s hard to say. After all, after the construction of the space station is completed, he will definitely have to work there for a while.

By then, it would probably take ten days or half a month to go there once.

"That's good. Look, Wen Qiang isn't even close to you anymore!"

"Who said that? Good boy, call me daddy!"

Xu Damao took out a piece of jade carving and teased Xu Wenqiang.

"Dad, Daddy!"

The little guy is smart. He knows that he can only give away fun things after calling his dad.

After resting at home for two days, Xu Damao went to work.

And they also found time to send seventeen Iridium communications satellites directly into their corresponding orbits.

During this period, Nie Feiyang, who was also the chief engineer of computer engineering at the Red Star Factory, and Fan Yong came to see Xu Damao.

Discuss the related work of long-distance networking.

"Mr. Xu, look, if we want to achieve nationwide interconnection, we need too many optical cables.

Can we use other methods to solve this problem?

For example, can we directly use satellite communication systems to complete ultra-long-distance data exchange? "

The local area Internet in Sijiu City, Tianjin and Phoenix City has been completed.

And after running for such a long time, many problems were found.

However, it still has a very significant effect on improving work efficiency.

Therefore, it is required that all important cities across the country be included in the network links.

This workload is enormous.

Not to mention other work for now, just building optical cables across the country is a very troublesome task.

After learning that Xu Damao was working on the Iridium satellite communication system, Nie Feiyang and Fan Yong began to wonder whether ultra-long-distance data transmission could be accomplished using satellites?

“Forget it. Unless we directly implement the Starlink project, there is absolutely no way to use satellites instead of optical cables for data transmission.

However, if you want to develop Starlink, you need to launch at least 20,000 satellites.

This is not something the current republic can afford.

And even if I get Starlink done, we don’t have that many relevant practitioners to maintain it.

Therefore, for now, let’s build a nationwide optical cable information highway!

By the way, the optical cable factory should have trained a lot of talents over such a long time. Shouldn’t we expand the scale and develop several branches?”

If Xu Damao really wants to develop Starlink, he can do it in a few years.

After all, a small satellite like that wouldn't take long.

However, the operation and maintenance work after it is completed is not so easy.

At least in the current Republic, there are not so many professional personnel who can carry out this kind of work.

"Optical cable factories have already started to differentiate and incubate, with Yangcheng, Bingcheng, Chang'an, Tianfu, Jiaozhou and Shencheng all preparing to build optical cable factories.

The optical cables they produce are mainly to meet the network construction needs of these cities and their surrounding areas.

But if we really want to build a national information superhighway, these few factories are still not enough.”

In nearly a year and a half, the Republic's computer and related industries have developed extremely rapidly.

The monthly computer output of the Red Star Semiconductor and Microelectronics Branch is approaching 300,000 units.

If we want to continue to expand the scale of production, we can only open branches in other places.

As for the Sijiucheng headquarters, there is simply no room to add more production workshops.

Nearly half of the computers produced remained in the country.

After the top leaders discovered the huge scale of the computer industry, they immediately established a principle of domestic priority.

As long as there is domestic demand, the proportion of computers exported cannot exceed 50%.

This is also why the domestic computer industry has developed rapidly.

After all, the country's installed computer capacity has now reached more than one million units.

This is also the reason why we require that a nationwide computer network be built as soon as possible.

"If not, we can first build local area networks in several city clusters, and then find a way to link the local area networks together. On the other hand, we must continue to expand the scale of production.

This thing is not only needed by us, but there will also be a huge demand for it abroad in the future.

For the time being, there will definitely be no overproduction.

Mr. Nie, you also need to make careful plans for computer production.

We can’t rely solely on our Red Star Factory. If anything can be separated out, just break it up and separate it out.

As long as we control the production of chips, processors, and memory sticks, we don’t have to worry about anyone stealing our technology.”

In later generations, the annual sales volume of computers is two to three hundred million units.

The current production really cannot meet the needs of the entire market!

Even purchasing representatives from many countries have begun to reside in Beijing, hoping to establish good relationships with the sales staff in the Republic and gain more market share.

For this reason, many places in the city have started infrastructure construction.

Even Director Yang was called over to assist with the design and planning work of other parts and the unit's living quarters.

After all, the Red Star Community, which has been put into use, can be regarded as the most mature modern community in the entire city.

Not to mention in China, even many people from Western countries who come here are very interested in this kind of employee living community with complete supporting facilities.

“Don’t worry, Director. We have already planned the division of the computer industry chain and even the division of computer assembly and production.

In addition to our city of Beijing, Tianjin, Shanghai, Yangcheng and Bingcheng will also build computer factories.

At that time, we will provide support with relevant technology and personnel.

Director, since we have time today, can you tell us about the Starlink project?"

Nie Feiyang is now very interested in the Starlink project that Xu Damao just mentioned, and he also knows what kind of communication plan would require so many in-orbit satellite networks.
