Another world conquest manual

Due to the unknown interstellar orbit of the Great Mo Realm, satellite communication is temporarily unavailable.

In this case, there are only two ways to achieve signal transmission in a short time:

Set up relay points, or radio beacons.

As everyone knows.

When using microwave and ultra-short wave signals to transmit signals, when the distance between the two terminal stations exceeds the line of sight.

The signal will begin to decay rapidly, making it impossible to guarantee signal quality.

The relay station refers to a site established between two terminal stations.

The relay station amplifies, shapes and converts the carrier frequency of the signal sent by the previous station before forwarding it to the next station.

In this way, the communication distance can be extended and good communication quality can be maintained.

At the same time, considering that the caravan will set off in ten days, there is basically no need to think about the ground relay station.

So there are currently only two possible relay methods:

Drone or high altitude balloon.

Of these two methods, the most impractical is drone relay.

The height of the drone relay is 300-2000 meters, and the range of use is within 200 kilometers-for example, the drone relay is used in the camp to explore Xiaolianzi Mountain.

But when the distance reaches more than 1,000 kilometers, the drone relay becomes somewhat unstable.

After all, there are quite a few people in the Great Mo Realm who can fly.

In the foundation building stage, the height that can be fully lifted into the air can be close to three hundred meters, and in the pill forming stage, it can reach one to five thousand meters depending on the level.

These monks are not interstellar players, they all have good eyesight.

Who knows if they will send a flying sword to chop it up when they see the drone - the rabbits are not worried about the drone being exposed. After all, technology and cultivation are two completely different civilizations.

Based on the understanding of the natives of the Great Mo Realm.

When they see a mechanical device like a drone, at most they will think it is a magic weapon tinkered by a certain family.

But once a drone is captured or exploded, its relay function will completely disappear, and the signal transmission will be completely ineffective.

The same goes for balloon relays.

The rabbits' technology in balloon relaying is not very advanced. The number of relay balloons required for 1,000 kilometers is at least 11 - the bear next door can do seven for 1,000 kilometers. This is one of the few communication systems next door that is better than us. technology.

So after eliminating the two relay methods, only radio beacons are left.

Radio beacon communication is actually a very complex thing, and its propagation characteristics are determined by the frequency characteristics used.

In short, long waves are thousands of kilometers long, medium waves are hundreds of kilometers long, short waves can reach the whole world through ionospheric reflection, and frequencies above ultra-short waves can only be transmitted in straight lines.

Sometimes, because a certain mountain peak is one Pandora's standard unit higher, communication signals may be greatly affected.

Considering the distance between the cities, there are currently only two feasible bands:

Long wave or short wave.

Short waves need to be reflected through the ionosphere, but unfortunately, the camp currently still knows very little about the characteristics of the ionosphere in the Great Mo Realm.

After all, there are three suns in the sky, and it’s hard to tell what high-energy particles are like—in an unknown world, the starry sky is really not a field that can be easily solved.

So after all the above possibilities are eliminated, there is only one possibility left:

Radio transmission using long waves.

It is still well known.

Long wave refers to radio waves with a frequency below 300kHz and a wavelength of 1000m to 10000m.

There is no doubt about the transmitting capability of the long-wave band, but there is a very, very troublesome problem in setting up it——

That is to say, a very huge long-wave antenna array is needed. Forget about ten ears, let’s change it to one this time, and it is hundreds of times larger than ten Murloc IIs.

This kind of antenna array is so huge that even rabbits are not willing to build it at will - in our country, long waves are generally used in the ocean industry.

Well, in the offshore industry, we don’t know anything about big black fish or small flat tops.

"I don't know if ten days is enough."

Lin Li pressed his temple with his thumb joint. This was another very important incident after the two-headed ox.

Considering that the caravan's travel might involve the next battle, and that the antenna array could not be decided by the camp, Lin Li hurriedly wrote a report, and Lin Ziming personally sent it back to the Magic City.

Three hours later.

Lin Ziming came back with new pinholes, no, new instructions:

The core layer will secretly transport a 40-meter hyperboloid reflection antenna array from Jiaoao City. Since there is no radio interference in the Great Mojie, the maximum communication distance of this array can reach 3,600 kilometers.

This antenna array covers an area of ​​about 2,560 square meters, and it is entirely possible to build and debug it within ten days. (I spent an hour checking all public array information across the country. The one in Jiaoao has been sealed in storage for a year just after it was retired. There is no case of disassembly and discovery. After it was manufactured, it took 400 people to assemble it. 17 days, and 33 hours of debugging after assembly. It should be reasonable for Da Mojie to double the manpower and shorten it to ten days)

At the same time, the core leadership also requested the camp to list candidates for the trip as soon as possible.

After handing over the instructions, Lin Ziming stayed directly at the headquarters and discussed the selection issue with many leaders who were still in the camp.

"My opinion is to send a few more people to accompany the Wei Mansion's caravan."

Vice-captain Zeng Gucheng spoke first. Recently, he has been busy assisting military experts in fine-tuning ballistics:

"Our trade volume this time is not small, and there are a lot of spiritual stones. Is it possible if we only send a few people? Well, although the people who come to the Great Mo Realm are all determined warriors, I don't think there is any need to deliberately create an environment to challenge human desires.”

"Seconded!"

Ma Ning raised his hand in agreement:

"I suggest that the Ministry of Commerce take the lead for the trade staff, maybe four to five, and then arrange for a few people in charge from our camp to follow. It would be best to form an elite team to accompany us all the way."

Hua Jun was also dragged to the meeting due to the reason that Bixing might buy talismans. He only heard him ask:

"Everyone, I have two questions.

First, if the trade volume is large, how are those materials carried along the way?

There are always five tons of various parts and components for more than two thousand demonic beasts, right?

The second question is.

If we want to trade, why do we have to follow the people from the Wei family instead of arranging a separate group of people to trade? "

Lin Li and Zeng Gucheng looked at each other, and then he said slowly:

"Academician Hua, the first question involves a secret of the Wei Mansion. Since everyone is here today and the confidentiality level is sufficient, I will tell you straightforwardly:

The Wei Mansion has a space storage bag that can store about 500 cubic meters of supplies - similar to a 10x10x6 specification. This is also a family heirloom left by Comrade Wei Siming. "

Seeing the surprised expressions of everyone present, Lin Li pointed at Zeng Gucheng and said:

"Lao Zeng and the others have studied this space bag, but unfortunately they have not been able to analyze any principles - note, any.

Therefore, we have not mentioned this matter publicly.

In addition to the nature and importance of the space bag to the Wei Mansion, we returned it to the Wei Mansion after a rough study.

The reason why the core layer agreed to our trade plan this time when the transshipment volume was almost full was, firstly, to prepare for the battle, and secondly, to be able to purchase a space bag of our own. "

After Lin Li finished speaking, Zeng Gucheng on the side sighed leisurely:

"Space technology, space technology."

For a moment, there was a silence in the headquarters.

space technology.

These four words do not need any explanation. Any person on earth with a normal IQ can understand its meaning.

After a while, Lin Li continued to speak:

“As for the second question raised by Academician Hua, I also discussed it with Director Shi while waiting for the reply from the base camp.

He told me that caravans like the Wei Mansion generally have their own unique resources and connections, and can contact many merchants that we cannot contact. This is the 'qualification' that we currently lack."

In addition, the person with the highest cultivation level in our camp is Comrade Cao Yi, who is at the peak of the first level of Qi training.

Think about it.

What would happen if a group of mortals went shopping with tens of thousands of spiritual stones?

Even though we have firearms that can temporarily make up for the shortcomings in cultivation, those practitioners don't know these concepts.

Going to that city is easy, but once we reveal our wealth, do we have to fight all the way back? "

Hua Jun was silent for a while and nodded slowly:

"Then I'm fine."

Then Lin Li looked around and said:

“In that case, let’s decide on the candidate.

I suggest.

The trade representatives of the trade delegation were composed of several officers from the Ministry of Commerce stationed in Chi County. The accompanying team was led by Colonel Lin Ziming, and was accompanied by an armed squad led by Comrade Gu Junming, the chief of staff of the armored regiment.

If you have no objections, let’s start voting! "

The last few days for double monthly passes, please vote! !

Currently, the new book monthly ticket list is still seventh! !

Py is a book by an old author. I personally think that the only dragon fanfic that I can read at Qidian is "I have no money to go to college, so I can only slay dragons."
