At the 911 air courier base, many tasks have high automation machinery to assist in, and do not require too much manpower.

After all, compared with the cost of machines, manpower is still quite high most of the time.

Especially with high education, college students are very expensive nowadays, and no one is willing to let them carry bricks and carry big bags.

What Chen Fei had to do was follow the instructions, click the buttons, and push and pull the joystick a few times, and it could be easily done.

Although these tasks are very basic and do not have any technical content, the several teams of the logistics department simply cannot spare any energy to deal with them at this critical moment. Everyone is working overtime to sort out container supplies, and they can hand over the simple work to Chen Fei.

For newly graduated undergraduate students, it is not difficult to get started. With a little tip, you can quickly become proficient.

In just a few minutes, Chen Fei had processed the accumulated domestic waste and kitchen waste for many days. The effect of the biodegradant automatically sprayed in the reaction tank was immediately effective. The odor that spread in the air began to fade rapidly. When the wind blew, there was basically no more odor left.

Under suitable temperature and humidity conditions, at most 24 hours, biological tissues and plastic components will be completely decomposed by various bacteria and active enzymes, turning into a ball of organic paste with complex ingredients but rich in compound elements such as nitrogen, phosphorus and potassium. After dehydration and granulation, it is a ready-made organic fertilizer.

Inorganic materials and metals that cannot be "digested" by biodegradants will be filtered out and then processed separately.

The work that really takes a lot of time is to deal with work waste from various departments, especially the failed aviation consumables and super-guaranteed accessories of the mechanics. There are all kinds of messy things, mostly metal, plastic, glass and ceramics.

Just like now, I rolled all the way from the "small hill" to the "small pot" at Chen Fei's feet, there are really everything!

He bent down and picked up the "small pot" and looked in his hand. He felt inexplicably appetizing and always wanted to try it. Chen Fei forced himself to suppress this strange "pica" idea. Like "visual", it is a sequelae brought by magic potions. It is probably impossible to treat it, and he must overcome it at all times.

It turns out that this rectangular "pot" is neither a hot pot nor a pot for cooking and cooking, but a directional antenna pot for sending and receiving radio signals in one go. Judging from the parameters printed on the back, it supports multiple frequency bands and can send radio signals to a distance of up to fifteen kilometers.

In addition to the slightly deformed external metal parts, this antenna pot with a diameter of about 30 cm looks roughly intact and may still be useful.

I originally wanted to give it a try, Chen Fei found more than a dozen wireless A-ends in a garbage dump like a hill. Perhaps the 911 air courier base is undergoing an old equipment replacement recently, and directly eliminated these old guys from their original positions and threw them all here to be decomposed and regenerated.

Try to power these AAP terminals and use your phone to connect, and they are all good and can be used normally.

This is simply a waste.

The full man didn't know that the hungry man was hungry, and the 911 air courier base would directly scrap the old A-side that could still be used, but the fellow villager Chen Fei had always had a communication and network disconnection like being isolated from the world.

If it can be used again...

Chen Fei felt a moment of emotion, and he didn't hesitate too much when he thought about it, and he quickly put it into action.

The pile of waste waiting to be processed is actually a small treasure, and you can always find some surprising gadgets.

After digging for a while, Chen Fei found eight-hole antenna pots, hundreds of A-ends of the same model, more than ten AC controllers, several different specifications of directional gain antennas, more than a dozen omnidirectional universal antennas, several large rolls of optical fibers, copper core high-speed network cables totaling over a thousand meters, more than a dozen pairs of full-duplex photoelectric signal relays, switches replaced with the A-end, some solar panels, several sets of chemical energy batteries with 60% capacity life, various specifications of DC transformer modules, more than a dozen stainless steel boxes, and even several book-sized mini computers. It seems that they are just catching up with the batch upgrade of network equipment at the 911 air courier base, and they have replaced such a lot of things.

After all, he is a serious undergraduate student. Even if he is in the Department of Economics, he has never eaten pork, and he has seen pig runs more or less. Chen Fei is not ignorant of what equipment is needed to build a home wireless network environment. He asks about everything and adds some bridging equipment, and big things can be accomplished.

Although the things that were taken out of the garbage dump came from different places and had their own different uses, they were pieced together to find the corresponding support protocols, frequency bands, interfaces and electrical standards, and form a segmented wireless communication relay network link, which is limited to civilian use, without too many requirements, and is not without feasibility.

The Logistics Department did not object to Chen Fei's idea, but instead provided some help.

After all, Teacher Shen is a neighbor of the 911 Air Flight Base. Both sides often have contacts and helping the neighbors to help the Internet. It is just a simple task, and it is also a waste utilization, so there is not much extra expenditure.

Rather than scrapping and decomposing these old equipment, it is better to continue to use the residual heat, and naturally I am very happy to do so.

He borrowed a high-precision contour map near the aircrew base from the tower, applied for a special public network interface from the communication group, and then used the free time of the target low-temperature nuclear fusion energy tower to serve night shifts, Chen Fei quickly planned the docking plan of the wireless relay link and assembled some equipment.

He planned to build a signal relay every eight kilometers between the 911 air courier base and the mountain primary school. Two directional antenna pots were responsible for listening to radio signals in different directions, converting and amplifying signals in the communication A-terminal terminal, using solar energy as the source of electricity, chemistry battery energy storage, and capacitive battery as backup redundancy. Full power can be used for a week at a time, which is enough to cope with extreme weather.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! The maximum bandwidth of the entire relay network link can reach 6742mbps. Including interference and losses, it can retain at least 40% to 50% of the stable bandwidth. The signal delay is not too exaggerated and is completely sufficient to use, and even in rainy and snowy weather, it will not have much impact.

On a rare day off, Chen Fei started to do it himself.

An outdoor optical fiber was pulled out from the gate of the 911 air courier base. Along the way, he drilled his holes in the rock, inserted rock nails, and fixed the optical fiber. It was not until he was five kilometers away from the base that he used three recycled metal pipes and foam cement to build the first relay station.

The transmission power of the active antenna pot has 30,000 yuan, which leaves enough redundancy for climate interference. It also has the wifi antenna on the A-end, which can cover network signals within a radius of 500 meters outdoors.

From the 911 air courier base to the mountain primary school where Teacher Chen Fei is located, the walking distance is about 21 kilometers. A fiber is saved by 5 kilometers away, and the remaining 16 kilometers only requires three relay stations.

It doesn't take much time to build a relay station, and it can be done in just half an hour, because many of the work was prepared by Chen Fei in his spare time.

The most time-consuming thing is to transport equipment along the ridge.

After two trips in the middle, Chen Fei pushed the wheelbarrow and arrived at the location of the last relay station until the sun sets west.

There were barking sounds of dogs in Teacher Chen Fei’s school yard, and the two dogs, “Amao” and “Ahu”, were barking endlessly.

As the school approached the barking of dogs, there was no movement at all, Chen Fei shouted loudly: "Teacher Shen, it's me!"

He knew very well that the two dogs suddenly barked because he was just projecting a laser beam to the school location at the second relay station.

Although dogs can only identify a few colors, they can still keenly detect abnormal bright spots.

The distance between the relay station and the school is closer than planned, and is only about 6.7 kilometers, which means that the signal will be stronger and more stable.

"Huh? Chen Fei, it's you! I was so scared. Classmates, it's okay!"

Chen Fei's head was poked behind the courtyard wall, and there was a muzzle. When he saw that it was Chen Fei and he was pushing a wheelbarrow, he immediately breathed a sigh of relief.
