Chapter 75 Telecommunications

The project of building houses for the traversers also started. Compared with the previous infrastructure construction, this project is much simpler. The simple houses are constructed of standard parts like building blocks, and the construction is not difficult.

The foundation of the residential area has been properly raised by 2 meters, one is to prevent possible floods, and the other is to resist from a condescending position in case of an attack.The slope of the entire foundation is made of stones and the ground is hardened.The simple houses adopt the common determinant layout in the new village. All the houses are arranged in a unified block facing south, and are arranged into seven groups around the central square, which are numbered clockwise with Arabic numerals. Groups one to five are single dormitories for men. The six groups are dormitories for women's singles, and the seven and two groups are family units.There are 4 people in each dormitory for singles, and one for each family.According to the past ideas, the simple room is equipped with a comfortable environment as much as possible, with electric lights and power sockets installed, but there is no furniture - the current wood has to be given priority to infrastructure projects - even so, many people are happy , for the first time in more than ten days, I can sleep in a real house, the laptop can be charged again, and the night life is no longer boring...

Rows of drying racks are built on the square of the living area, and a row of houses on the north side of the square are toilets and washrooms.Brand new flush toilets were unloaded from the ship—not domestic toilets, but squat toilets commonly known as “Turkish toilets”—which the executive committee felt were more hygienic without direct contact with the skin.The water used to flush the toilets is drawn directly from the river and stored in a simple water tower behind the toilets. Bairen City has been supplying water by quality since its establishment.

The lavatories and toilets use the same set of drainage facilities. Under the gravity of the height difference, the sewage is directly discharged into the agricultural area downwind of the residential area through the sewage channel. Wu Nanhai built a large biogas tank, and all the sewage in the city are all processed here.

The periphery of the entire living area is piled with earth and stones to form a low wall with a height of one person. It can be used to resist when necessary. There is only one entrance to the living area. The door on the steps is made of strong wooden boards, and there is a stone cement mortar next to it. The duty room on the second floor was actually a bunker, and the staff of the security team are usually on duty 24 hours a day.

The office environment of the executive committee has also improved, and a two-story steel-frame simple building has sprung up. The interior decoration here is much more magnificent, and the furniture is all taken from the Fengcheng wheel—these Old-fashioned furniture that used to look old now looks luxurious and stylish, making many people jealous.There is even a LAN in the office!There are rumors among the masses that some members of the Executive Committee play online games in the office every night.

This put a lot of pressure on the communication team that just got an office in the executive committee building. Many people came to the team leader Li Yunxing to ask for the network interface to be connected to every room as soon as possible. Some people worried that there were not so many routers. If there is one interface in the room, everyone cannot surf the Internet at the same time.It is simply recommended to fully open the wireless Internet service. Anyway, most people's notebooks have this function.

This request was ruthlessly rejected by the executive committee, and Yan Maqianju instructed him to set up a communication center in Bairen City as soon as possible.

The solution adopted by the communication team in the communication plan before the crossing is actually the PHS system that has been eliminated now. Of course, this communication system is not ideal in reality, and it is often "hey, hey, fuck".However, as a cross-travel communication device, it has the characteristics of simple structure and low energy consumption. As for the problem of poor signal, there was no radio interference in the air in the 17th century, and there were no numerous buildings and high-voltage lines.

Li Yunxing brought a set of disused PHS base stations and controllers from local telecom, as well as 2 laptops, obsolete telecom servers, various communication cables, interface devices, communication protocols, communication management software and a complete set of communication management software.These things are enough for him to build a wireless communication network in this time and space.

Such a set of PHS base stations and controllers can support thousands of PHS mobile phones within a maximum radius of dozens of kilometers. If a few remote modules are added, it can also support a longer distance. The internal communication of the base is sufficient for a considerable period of time. used.

There are more than 1000 PHS mobile phones, all of which are purchased in batches with the same signal and the same batch, so that parts can be replaced and repaired at that time.

He estimated that the transmission power of the existing base station is about 50w, which can cover a cellular area of ​​15km. To meet the requirements of the executive committee, the base station coverage should reach about 35km to 40km, and a base station power amplifier should be installed. Increase the transmission power of each channel to 200w, which can greatly increase the fading reserve of the system at the same time. In order to balance the power, a tower-mounted amplifier must also be installed to increase the uplink signal by about 12db.Overall estimation, the entire base station is powered by 230v50hz AC, and the required power is 7-10kw.At present, the report is submitted to the executive committee to request a power supply quota, but now the Guotuoji Power Station can provide 200KW of electricity per hour, and this power should not be a problem.

The communication team applied for the help of the engineering team, built a tower in the city, and installed an array antenna, which can reduce the echo noise of the surrounding buildings. Of course, there are no high-rise buildings in this place at this time, but it is always right to raise it higher.

Mr. Wen suggested that various wireless resources should be integrated as soon as possible so that radio stations, mobile phones, and walkie-talkies can communicate with each other.For this reasonable request, Li Yunxing thought hard for a long time, and then called all the team members together to study it. Finally, he had to adopt a local method to solve it: use the air public interface protocol to provide cluster scheduling for everyone's walkie-talkie—temporary A server was set up with an industrial single-chip microcomputer, and the signal of the walkie-talkie was simulated as a mobile phone signal to be connected to the switchboard. This solution not only required a single-chip microcomputer, but also installed an antenna because of the different frequencies between the PHS and the walkie-talkie.

The opening and use of PHS made everyone feel a little familiar. On the day when the numbers were distributed, there were crowds of people in front of the communication team office, and everyone wanted a so-called auspicious number.

"I want 888888!"

"I want 168168! All the way!"

"Fart, that's mine."

"Xiao Shao, do you still remember? I also treated you to dinner, leave me the one with 8!"

"You guys are so vulgar, you know you want 8, skinning?"

"It's called getting rich! Do you understand? Illiterate!"

"You are illiterate, your whole family is illiterate, and you are not from Cantonese, how can you learn your tongue from this man?" The two men almost exchanged fists and kicks.

"I want 6, bring me a 6!"

Some people planted it out of their own minds: "I want 444444"

"Then you might as well ask for 514514" someone joked him.

Shao Zong sat behind the table, and there was a big box on the table, he raised his throat and shouted: "Everyone, don't mess up, come one by one, we will check the number one by one here, if you don't choose a number, do you know? The one you touch is that one. Hey hey hey , I said you are so unconscious, you look at it and throw it back?! You have no quality!"

"Hey, Xiao Shao, can you give me a better phone? This phone is too ugly." This is the girl speaking.

"I want the flip one. Why are you all straight? Old-fashioned!" The women chattered, their interest was not in the numbers but in the pile of PHS phones over there - they were all rummaging there.

"Yeah, I don't have to choose the color... I knew I would have brought the one I didn't want at home..." These phones are purchased in bulk, except for the different colors, the models are exactly the same, no wonder the girls Dissatisfied.

Several people in the communication group tried their best to maintain order, but seeing the situation getting more and more chaotic, Guo Yi, who had been working nearby, stepped forward:

"Everyone, don't make a mess." He has never worked in the field of law and order, and he can be regarded as a person in the industry after all. He has never eaten pork and has seen pigs run away.Seeing that this situation is the time to behave, immediately stand up and help maintain order.A irascible guy tried to push Xiao Guo, and was pinched by his knuckles until he shed tears. With such a sad example, the noisy crowd immediately settled down.

The number selection ended soon, except for a few lucky ones who got the so-called auspicious numbers with 8 and 6, most of them were ordinary numbers.Some people who really believed in this but didn't get a number cursed unwillingly, went to those lucky ones, and offered to use their own materials and equipment to change numbers with them.

"Business opportunities are everywhere..." Shao Zong moved the desk back to the office contentedly, just like in another time and space, the communication group - the future time travel company, has already withheld those so-called auspicious numbers, Li Yunxing and Shaozong planned to put these numbers on the market once they crossed over to the telecommunications system reformation. Oh boy, wouldn't they make a fortune?

Seeing that the person who stood up to maintain order left without taking a number, he quickly chased after him:

"Brother, what's your name? Why don't you take the number and get your phone." He decided to give him a number with 8 in order to express his gratitude.

"Here," Guo Yi scratched his head and said a little embarrassedly, "I'm a temporary ID card, so I can't get a mobile phone right now."

"Oh!" Shao Zong clapped his hands suddenly, "You are that Guo Yi, right?"

"You know me?" Xiao Guo didn't understand. It must be because no one recognizes him here.

"Well, other people don't know, but I have read the internal report that our team leader brought back."

"Oh? What did it say?" Guo Yi was very concerned about his future, and the internal report undoubtedly represented the views and policies of the high-level leaders of this group of bold space-time adventurers.

"This..." Shao Zong thought for a while, "It's inconvenient to say, there is a secret level..."

Damn, it's really good to learn, this set of things can be mastered as soon as you learn it.Xiao Guo cursed secretly in his heart, but he still said with incomparable sincerity on his face: "It's okay, I'll just ask casually."

"Let me reveal a little bit." Shao Zong felt that it would be unreasonable to be too principled. "The three of you, the meaning of the executive committee must be different. You just need to remember this."

difference?What does this mean? Guo Yi fell into deep thought for a while.
