The county, which was like an isolated island before, resumed communication with the outside world, and the news was like a virus, which soon spread throughout the county.

After the communication, some rescue work in the county, the relevant departments also re-established contact with the superiors.

The loss of contact with the county has made all walks of life worry, but after the communication was restored, it can be regarded as a temporary relief.

And it was precisely because Li Anchor flew in the sky over Yan County that the people who were able to receive Li Anchor's signal in Luo County passed on some of their information.

Although it is not big, it also has more than 1,600 square kilometers, and the area is not very small.

And because Li Anchor's flight altitude at this time was only fifty meters, the range he could involve for the entire county of Yan County was not so large.

Li Anchor, who was flying the model airplane, was not clear at all, but the engineers of China Mobile, who had been monitoring the operation of the equipment, were very aware of this situation.

According to common sense, although the equipment they have newly developed is portable, it is not weak at all in terms of function.

According to the data they monitored, the current volume is not at full capacity.

Several China Mobile engineers were also quite puzzled, and some did not know what caused this.

If you want to say that there are only a few factors that can affect the signal, but the current Yuxian County will not cause such a situation at all, is it that after the flood, the obstruction is a little serious?

But just because of the occlusion, it is impossible to cause this situation at all.

"Is it possible that it's because it's not high enough, so the range of radiation to the periphery doesn't reach the maximum effect at all?"

As soon as the engineer's words came out, the other engineers present all felt as if they had been enlightened, as if this was really the cause.

According to the base station they usually build, the height of the base station tower is only 50 meters high, which can radiate five kilometers of communication in the surrounding area.

If you calculate it this way, the current model aircraft of Li Anchor is equivalent to the role of a base station, and the performance of their design is not fully exerted at all!

As for the solution, it is also very easy to do, that is, just raise their equipment as high as possible.

Knowing what the reason was, several engineers got together and hurriedly calculated what kind of height they could rise to in order to give full play to the performance they had originally designed.

After one calculation, and more than one calculation, the answer is that as long as the altitude of the model aircraft rises to an altitude of 300 meters, their mobile emergency communication equipment can exert its full performance.

Being able to increase the communication range from five kilometers to forty to forty-five kilometers, as for whether there will be any improvement if it continues to rise, it is not for them to know.

Several engineers first glanced at each other, and then glanced at the big screen showing Li Anchor's live broadcast room, and then one of the leaders picked up the phone and called.

These people are not the stunned young people like Li Anchor, and they are also in the case of superiors, of course, they have to report first, and after getting the consent of the leader, they can implement the previous ideas.

The engineer's conclusion was finally reported to the headquarters of China Mobile in Beiping.

Seeing their report to the leaders of China Mobile, they are not stupid, this is a once-in-a-lifetime opportunity, if they can really provide temporary communication to a county through this model aircraft, they will really show their faces.

Thinking about this, the manager of China Mobile also hurriedly made several phone calls to go out, and finally contacted the air traffic control bureau, and it was still the air traffic control bureau leader who had been paying attention to the situation in Li Anchor's live broadcast room.

"Zheng Ju, hello, I am the manager of China Mobile Beiping Head Office, and I called you this time because of the matter in Yu County.

I believe you also know that the drone over Yuxian County is equipped with our company's new emergency communication equipment.

Although we have restored communication in Yuxian, we are limited by altitude conditions, so we have not given full play to the maximum performance of the equipment!

I called you this time to discuss with you and see if there is any way to open the airspace over Yuxian County to the drone! ”

After hearing this, Zheng Ju of the Air Traffic Control Bureau immediately gave a straightforward answer, which was extremely in line with the style of the army.

"Regarding the issue of open airspace, we have already done a record on our side before.

Although Li Anchor's drone did not have a route and did not report at the beginning, when he made the decision to go to the rescue area, our bureau had already completed the filing for him!

In the low-altitude airspace below 1,000 meters above Yan County, Li Anchor's drones can be used freely! ”

When Manager Chu of China Mobile heard this, his face immediately became a little overjoyed, and then he hung up the phone without being polite to Zheng Ju.

After that, he was still busy, not only to contact Li Anchor to see if he could improve the flight altitude, but also to continue to negotiate with the upcoming China Unicom and China Telecom to reap the benefits.

Manager Chu hung up the phone of the Air Traffic Control Bureau, and then called Liu Ke, who had called before.

At this time, the sky has gradually darkened, and the sunshade umbrella used to shade the sun has no effect, and this umbrella cannot block the sun.

From the beginning of the sun to the westward inclination of the sun, Li Anchor has been flying for a day, coupled with the state of hovering over the county at this time, the two factors of boredom and exhaustion are added together, that is, sleepiness.

Li Anchor, who had been hovering for an unknown amount of time, was about to fall asleep at this time, but at this moment, Liu Ke's mobile phone rang again.

Liu Ke is accustomed to the fact that he rings from time to time, and it is still calls from unfamiliar numbers, so he is accustomed to common and strange.

Before he came, he didn't expect that he, a young and promising first-class police officer, would become Li Anchor's assistant this time, and his mobile phone was also contributed.

Liu Ke was very skilled, pressed the connect button on the mobile phone, and Li Anchor, who heard the phone ringing, also understood what was going on, and directly said hello.

"Hey, hello, I'm Manager Chu of China Mobile Corporation, I have contacted you before, that is, we want to ask you something, can you raise the flight altitude of the model aircraft to more than 300 meters?

Our equipment, at its current height, is not able to perform at its highest level! ”

As soon as he heard what Manager Chu of China Mobile said, Li Anchor immediately became energetic, there was such a good thing?

It was really exciting news to let him increase the flight altitude, but when he turned his head, he thought about his own actual situation, and don't forget that he was still a black flyer!

"Manager Chu, it's not me who refuses, you should also know, my model aircraft is still in a state of black flight!"
