Chapter 63: Wireless network distance

The wireless router acts as a signal base station, and the drone plugs into the sky at high altitude.
This is a theoretically feasible solution.
Suppressed his inner excitement. Shen Cong began to study this direction. For the stability of the equipment, he first guided King Kong to alloy the wireless router.
Repair some poor contact of the line caused by rust.
King Kong is currently "pseudo-Lv1.021" level, the reason is "pseudo" because it is clear that the "Lv1" as defined by King Kong before, can continue to expand. According to Shen Cong's level quantification, the Ultimate King Kong is the standard definition of "Lv1", which has not yet reached this standard and does not know the exact value.
Therefore, the current quantitative hierarchy system continues to use the old version that was previously defined incorrectly. In order to distinguish it, a "false" word is added to the front.
Pseudo-Lv1.021 King Kong, quickly adjust the activity, alloy the router.
The router is not a simple iron product, the alloy speed is a bit slow, but after half an hour, the alloy is completed.
Complete the alloy, turn on the power, connect all the equipment that can be connected to the wireless and have the office module, and connect the wireless router to form a local area network. Set up the management mode of the office module. Soon, Cong Shen used a mobile phone to enable the office module and took over all the equipment.
"The radar adjusts the rotation angle." Shen Cong operated on the mobile phone. Then, the radar on the roof did follow the instructions of the mobile phone and began to tilt an angle.
Shen Cong could not help but nodded: "The signal connection is very stable and the intensity is very stable. I ’ll test the effective distance while it is not dark."
If she was in the wild, Shen Cong got out of the car early.
But there are a lot of survivors here. It is not ruled out that there is danger and unnecessary circumstances. Shen Cong does not intend to leave the Vajrayana. He called for Zhang Youhai-in fact, Zhang Youhai has moved since he saw Shen Cong. He originally settled on a ruined floor a little further away, and now he is here.
"Hold this phone and go as far as possible. I have already connected the phone to the Internet. When the network is disconnected, you will come back."
"Boss, can you connect to the Internet now? Can you communicate with the outside world?" Zhang Youhai exclaimed, holding her mobile phone.
"No, LAN."
Zhang Youhai shook his head in disappointment, took the mobile phone, and walked away.
聪 Shen Cong stared at the mobile phone. At ten meters, the signal transmission was very stable; at twenty meters, the signal transmission was still stable; at thirty meters, the image transmission began to slow down; at forty meters, the transmission had been intermittent; at fifty meters, the signal was completely disconnected.
"Only 50 meters signal range?" Shen Cong frowned, which was half the distance of 100 meters he imagined.
"How?" Zhang Youhai walked back and asked curiously.
"Do you know the radiation interference in the air?" Shen Cong asked suddenly.
友 Zhang Youhai said, "Radiation interference? Yes, it's the end of the world. It should be radiation interference."
Shen Cong glanced at each other in surprise, Zhang Youhai didn't even know that there was a high intensity radiation in the air: "Do you have a Geiger counter?"
"what is that?"
"Doomsday must ..." Shen Cong found it difficult to communicate with Zhang Youhai. The Geiger counter is a doomsday product of waste soil type. For the detection of radiation concentration, basically anyone who has fantasies of doomsday will prepare one.
But thinking that the other party is just an ordinary person, Shen Cong will not continue this topic: "What do you think of evolution?"
进化 "Evolution ..." Zhang Youhai glanced at Shen Cong and said with emotion, "Envy."
"I'm asking you, what do you think of evolution?"
"Ah, this, how do I understand, isn't this what scientists should do? We are flat-headed people, we ca n’t even eat enough food, and don't worry too much."
Shen Cong frowned, not knowing if he was talking to himself, or saying to Zhang Youhai: "Don't always wait for others to do it ... you go back and wait for me to change the signal before I find you."
Uh ...
Suddenly, the truck door closed.
友 Zhang Youhai has become accustomed to Shen Cong's indifference. This last two months of end-of-life life, struggling and humiliation, has flattened his last bit of heart.
Facing the evolutionist, I instinctively felt that I belonged to the humble side.
In fact, even if he is not an evolutionary, as long as the other party has a gun, a weapon, and dares to kill, Zhang Youhai still feels humbler than the other party.
Before the cataclysm, he was in a small business every day and could n’t make a lot of money, but he could n’t have enough money to spend. He had fun with fox friends and dog friends. It ’s okay to blame the government for strict control, which makes people free. Don't mention how happy it is on a young day, and I don't think anyone is more noble than others. At most, the officials will make a fart, and then turn around and scold stupidity.
When the last days came, I knew what freedom was.
Without a powerful government control, this new society is a virgin forest with weak meat and strong food. Those who do not dare to kill people eat ashes, killing and setting fire, like Zhang Tianshen's group, eating human blood buns is delicious.
"Hey." Zhang Youhai shook his head with a mockery. "Evolution ... I just want to know what the evolution is like."
Uh ...
Speed ​​reduction at 30 meters, instability at 40 meters, and direct network disconnection at 50 meters.
Such a signal strength is far from Shen Cong's requirements.
He wants to design a scheme to amplify the transmission signal of the router and reduce the interference of radiation to the signal. For the electromagnetic signal, he still has some research. At the beginning, he scrapped the 15A radar, which he repaired by himself. Since the end of the day, I have always wanted to enhance the search intensity of car radios.
How much will I have some experience.
The wireless router alone is used as the base station, or the power is too low, and the signal is not far away.
If you can remove some mobile, China Unicom, telecommunications mainframes, and then remove some antennas and feeders back ~ EbookFREE.me ~, you can arrange King Kong as a mobile base station. In the neighborhood where Shen Cong used to live, there are a large number of hosts of three telecommunications companies on the walls of the corridor, including 3G, 4G, 2G and other types of hosts and cellular machines.
研究 He researched that he would build a simple small base station.
I do n’t have any equipment at the moment.
"Wait for Zhang Youhai to find if you can find some hosts from the ruins of the community, but it should be difficult. If I remember correctly, these hosts are installed in the elevator room on the top of the building ... the antenna will not be less, It's all there in the stairway, even if there's only one. "
What he wants most is to insert the drone into the eye. Even if it can't reach 200 meters, it can see at least a few kilometers away at 100 meters.
Of course, it is worth consoling that it has been verified that the signal can barely be transmitted at a distance of 40 meters, and the drone can already fly 40 meters. Compared with when there was no wireless router, it is less than ten meters away from the remote control station, which is a great improvement.
If it was n’t for the many people around here, Shen Cong would like to immediately take out the 8th generation of DJI Elf to perform some aerial operations and experience high-altitude investigations.
Glancing at my eyes, I found that in the camera picture, the old man Li and Wan Quan had returned.
Uh ...
的 The news brought back by the old man Li is that Wang Gen intends to sell diesel to Shen Cong. He has stored a lot, and basically he collected the gasoline and diesel in the south of the city.
"However, Mr. Huang and Brother Wang Gen hope to meet with you. I have disclosed to you that you are an evolutionary as you said. He wants to share with you the evolutionary experience of the evolutionary."
