Chapter 51

At the 911 Air Base, many tasks can be assisted by highly automated machinery, requiring minimal human labor.

After all, compared to the cost of machinery, human labor is often quite high.

Especially for those with high education, today's college graduates are very precious, and no one would really let them do heavy lifting and carry large packages.

What Chen Fei needed to do was to follow the instructions, press a few buttons, and manipulate the control levers a few times, and he could easily get the job done.

Although these tasks were very basic and required no technical skills, the logistics department's several teams were particularly busy at this critical moment, all working overtime to sort out container supplies. They could just hand over the simple tasks to Chen Fei.

For a recent college graduate, there was no difficulty in getting started. With a little guidance, he could quickly become proficient.

In just a few minutes, Chen Fei had processed the accumulated household and kitchen waste. The biological degradation agent automatically sprayed into the reaction tank had an immediate effect, and the stench in the air quickly dissipated. After a breeze, there was hardly any odor left.

Under suitable temperature and humidity conditions, it would take no more than 24 hours for the organic and plastic components to be completely decomposed by various bacteria and active enzymes, turning into a complex organic slurry rich in nitrogen, phosphorus, and potassium. After dehydration and granulation, it would become organic fertilizer.

Inorganic materials and metals that could not be "digested" by the biological degradation agent would be filtered out and processed separately.

The truly time-consuming work was handling the waste from various departments, especially the failed aviation consumables and over-maintained parts from the maintenance team. There were all sorts of things, mostly metals, plastics, glass, and ceramics.

Just like now, a "small pot" rolled down from the "small mountain" to Chen Fei's feet. It was really a mixed bag!

Bending down to pick up the "small pot" and examining it, Chen Fei felt an inexplicable urge to taste it, as if he wanted to take a bite. He forcibly suppressed this strange "pica" urge, which, like "hallucinations," was a side effect of the magic potion. It was probably incurable, and he had to constantly overcome it himself.

It turned out that this rectangular "pot" was neither a hot pot nor a cooking pan, but a directional antenna for transmitting and receiving radio signals. From the parameters printed on the back, it supported multiple frequency bands and could transmit radio signals up to 15 kilometers away.

Apart from some slight deformation of the external metal parts, this 30-centimeter-diameter antenna dish looked relatively intact and might still be usable.

With a mindset to give it a try, Chen Fei found over ten wireless APs in the mountain of garbage. Perhaps the 911 Air Base was recently upgrading its old equipment, directly phasing out these old devices and leaving them here to be decomposed and recycled.

When he tried to power these APs and connect them with his phone, they all worked perfectly and could be used normally.

This was such a waste.

Those who are well-fed don't understand the hunger of the hungry. The 911 Air Base was directly scrapping and recycling old APs that were still usable, while Teacher Shen Fei in the countryside had been isolated and without internet communication.

If these could be reused...

Chen Fei's heart raced, and without much hesitation, he quickly took action.

The pile of waste waiting to be processed was actually a small treasure trove, and he could always find some surprising little gadgets.

After digging for a while, Chen Fei found eight more antenna dishes, over a hundred APs of the same model, a dozen AC controllers, several types of directional gain antennas, a dozen omnidirectional universal antennas, several large rolls of optical fiber, a total of several thousand meters of copper core high-speed network cables, a dozen full-duplex optical-electrical signal repeaters, switches replaced along with the APs, some solar panels, several chemical batteries with 60% remaining capacity, various DC transformer modules, a dozen stainless steel boxes, and even a few mini computers the size of a book. It seemed that the 911 Air Base was in the process of a large-scale network equipment upgrade, which resulted in this pile of old equipment.

As a genuine college graduate, even though he studied economics, Chen Fei was not entirely ignorant about the equipment needed to set up a home wireless network. When in doubt, ask AI, and with some bridging equipment, the task could be accomplished.

Although these old devices came from different places and had different original purposes, they could be pieced together, finding corresponding support protocols, frequency bands, interfaces, and electrical standards to build a segmented wireless communication relay network. For civilian use, with minimal requirements, it was not impossible.

The logistics department did not oppose Chen Fei's idea but even provided some assistance.

After all, Teacher Shen was a neighbor of the 911 Air Base, and both sides often interacted. Helping to set up internet access for the neighbor was just a small effort, especially since it involved recycling waste, with minimal additional costs.

These old devices, rather than being scrapped and recycled, could continue to serve, and they were more than willing.

Chen Fei borrowed a high-precision topographic map of the area near the air base from the control tower and applied for a dedicated public network interface from the communications team. Using the free time during his night shift at the Target low-temperature nuclear fusion energy tower, he quickly planned the layout of the wireless relay link and assembled some of the equipment.

He planned to set up a signal relay every eight kilometers between the 911 Air Base and the mountain school. Two directional antenna dishes would handle the transmission and reception of radio signals in different directions, the communication APs would convert and amplify the signals, powered by solar energy, with chemical batteries for storage and capacitor batteries as backup. A full charge could last for a week, sufficient to handle extreme weather.

The highest bandwidth of the entire relay network could reach 6742 Mbps. Considering interference and loss, it could still maintain a stable bandwidth of at least 40-50%, with acceptable signal delay, more than enough for use, even in rainy or snowy weather.

On a rare day off, Chen Fei began to work on it himself.

He pulled an outdoor optical fiber from the entrance of the 911 Air Base, drilling holes in the rocks along the way, inserting rock bolts, and securing the fiber until he reached a location five kilometers from the base, where he built the first relay station using three recycled metal pipes and foam cement.

The active antenna dish had a transmission power of 3W, with sufficient redundancy for climate interference, and the AP's own Wi-Fi antenna could cover a 500-meter radius outdoors.

The walking distance from the 911 Air Base to Teacher Shen Fei's mountain school was about 21 kilometers. The first 5 kilometers were saved by the optical fiber, leaving 16 kilometers to be covered by three relay stations.

Building the relay stations did not take much time, about half an hour each, as much of the work had been prepared by Chen Fei in his free time.

The most time-consuming part was transporting the equipment along the mountain ridge.

After two round trips, Chen Fei finally pushed a wheelbarrow to the location of the last relay station as the sun began to set.

The barking of dogs in Teacher Shen Fei's schoolyard was continuous, with "A Mao" and "A Hu" barking incessantly.

As he approached, the barking suddenly stopped, and the school became completely silent. Chen Fei called out loudly, "Teacher Shen, it's me!"

He knew the dogs had been barking because he had projected a positioning laser beam from the second relay station to the school, which had startled them.

Although dogs can only distinguish a few colors, they can still敏锐地察觉到异常的明亮光斑。

The distance between the relay station and the school was closer than planned, about 6.7 kilometers, meaning the signal would be stronger and more stable.

"Hey? Chen Fei, it's you! You really gave me a scare, students, everything's fine!"

Shen Fei's head appeared behind the wall, along with the barrel of a gun. Upon seeing Chen Fei pushing a wheelbarrow, she immediately relaxed.
