Chapter 547? 2G mobile communication system grid connection test (9) [seeking subscription]
"Yes!" Zhu Xiaolong came to Xu Zhenming's desk and began to guide data into Xu Zhenming's laptop.
Xu Zhenming picked up the helmet on the bookcase and put it on, and hurriedly walked downstairs to Zhang Guoli's laboratory.Not long after, came to Zhang Guoli's laboratory.
"Once there is a signal, I am ready to start a test call. It is best to test online with 10 pairs of mobile phones!"
At this time, Zhang Guoli smiled like a child and directed his colleagues to prepare to test the PHS system.
In the laboratory, the computer screen of the PHS base station console shows that it has successfully connected with the base station of Siya Building.In other words, the pilot test of the PHS system can be carried out at this time.
Left-click came to Xu Zhenming's side with a smile, and handed a flip phone.
Xu Zhenming glanced at the screen of the phone, and the 5 bars of signals were full.This shows that the signal of the PHS base station of Siya Building can cover 278 kilometers, which is very powerful.
But Xu Zhenming believed that this was not enough, and decided to drive out with the left button and go to the easternmost end of the Nan'an Economic Development Zone for a test.According to the map of Nan'an, there should be more than 30 kilometers away from Siya Building.
"Okay! Team Leader Xu is determined to do it in one step, first test the signal function of the PHS base station!" Left-click smiled, and hurriedly got into the car with Xu Zhenming.
The two of them drove out of the Nan'an Economic Development Zone and have arrived at the boundary of Suning City.At this time, the signal strength of the two of them was still a 5-segment model.
Seeing this situation, the left button couldn't help but raised a thumb: "Xu Zhenming! The signal strength of your PHS system is nothing to say, it can reach a range of at least 40 kilometers!"
In fact, it should be!
PHMA's communication protocol standard is another 3G communication protocol standard made in China in time and space. Don't be too advanced in this era.
Xu Zhenming didn't say that much, and according to the old rules, first sent a short message to the left button.
Sure enough, a short message from Xu Zhenming was received by the left button after a while.He then started calling Xu Zhenming's phone, and the two talked on the phone after a hundred meters apart to test the effect of the call.
No matter how you experiment, the call effect is very good, there is no clutter, no sound distortion.From this point of view, the PHS system has been successfully piloted.
"Go! Let's go back to the laboratory and start doing experiments such as hacking and monitoring!" After the experiment, the left button smiled at Xu Zhenming happily.
He actually knows that the PHS system is fine, and it can even support the mobile phone network to connect to the Internet. The bandwidth speed of 256K is much faster than the dial-up Internet speed of the post office.
Not long after, the two had arrived in Zhang Guoli's laboratory.
"Report to Mr. Xu! We have tested it ourselves, and the pilot experiment of the PHS system is completely normal!"
"Mr Xu, come and see, we use the PHS system to access the Internet, and the speed is really fast!"
As soon as they entered the laboratory, Zhang Guoli and others all smiled and reported the situation.
This group of people deliberately built a modem in their spare time, and can use the PHS calling card to access the Internet server of Yiming Group.
Yiming Group’s computing center communicates directly with satellites and directly connects to the Internet. The network speed is much faster than general access points in China. It is very convenient to do this kind of experiment without spending telephone or communication fees.
"I'll take a look!" The left button, who had just thought of this idea, yelled in astonishment.He didn't expect that the technical team of Yiming Group Company was so impressive that it had already made PHS equipment that could be used for the Internet.
This kind of equipment is very important, and the Longbow Group needs it, at least more than 100,000 sets.As for what purpose?That is a military secret, inconvenient to disclose!
Thinking of these questions, left click to come to a computer and stared at a small box the size of a mobile phone, with his eyes glistening.
This small box is a modem for the mobile phone card to access the Internet, nicknamed "cat"!
This cat has an antenna facing the sky at the tail, a mobile phone card can be inserted on the front, and a network cable interface and a power interface on the back. It is not large and the workmanship is not bad.At this point, the tail network cable of this "cat" has been connected to the computer.
Left-click to open the application applet on the computer, and saw the interface of dialing the Internet through the "cat", and a surprised look appeared on his face."Do you still need to dial the phone to get online?" He said to himself.
"Zuo Gong! Mobile dial-up Internet access is only one of the methods! In fact, as long as the PHS signal network, our modem can access the Internet! Of course, the PHS signal network must have an access server!"
At this time, the engineer in charge of developing this equipment came to the side of Left Button and smiled and explained.
"Okay, good! This kind of equipment is so good, our unit has a need, first come 100,000 little cats who can only surf the Internet!" After the left-click understood the principle, he laughed.
He immediately took out his cell phone and talked with a leader far away in the capital.
"Report leader! The pilot test of the PHS system has been successful! I found that they have a new equipment, which is helpful to our No. 2 project!" Left-click smiled with a reddish face and introduced the situation of the "cat" again.
At this time, a majestic voice came from the phone, "Let Yiming Group immediately send the PHS system and modem to the capital. You should also return to the capital soon!"
"Yes, Chief!" Left click to stand at attention and replied excitedly.
After hanging up the phone, he almost couldn't control his emotions. He paced back and forth, muttering words: "Project No. 2 is successful! Our Longbow Group has come up with good things of the world's advanced level! Haha..."
Seeing his extremely excited appearance, Xu Zhenming can also guess some signs: "Is it the digital armored division's equipment? It should be similar!"
The level of confidentiality of military secrets involved in the left button is relatively high, Xu Zhenming has no right to know, nor can he inquire casually.His current task is to do a good job of service, do a good job of "cats", and just earn money home.
Mindful of this, Xu Zhenming called Captain Zhang, who was under construction, to ask about the status of the base station installation and when will the PHS and the fixed telephone network of the post and telecommunications system be connected.
"Report team leader! We are working at the Xicun site at this time, and the construction team of the Nan'an Post Office seems to be in trouble!" At this time, the phone came to the phone with a wry laugh from the team leader.
He told Xu Zhenming that the Jinggong Electromechanical Company, which has long undertaken the postal and electrical external line project, sent more than 100 migrant workers to surround the construction site where they worked.
This group of people are here to ask for pay, and it is said that Nan'an Post Office owed their company the project payment.They have not paid wages for several months.
Because of this incident, the site in West Village was unable to carry out base station installation operations.Not only that, there is also a group of migrant workers making trouble in the courtyard of the Nan'an Post Office headquarters, which may affect the installation of the PHS base station in the post and telecommunications building!
Is this okay?
Left click to wait for the grid connection test of the PHS system to be completed today, and fly directly to Beijing with the data report.He will fly to the west with the electronics experts of the Longbow Group to start research and development of the digital command system for Project 2.
"Captain Gui! I am the left button, I need your support now!" Thinking of this, the left button immediately took out the phone and said what he had heard from Xu Zhenming's call.
After a while, Gui Changshu's roar came out on the phone: "What a fuck! Don't worry, I will handle this with the local comrades immediately!"
Seeing this situation, Xu Zhenming, who had just finished hanging up, couldn't help but smile a little bitterly.
He didn't want the Longbow Group to intervene in such small civil disputes.Anyone with a discerning eye can see that the Jinggong Mechanical and Electrical Engineering Company, which deliberately sent migrant workers to make trouble, must have a problem. Is it just deliberately disturbing the installation of the PHS base station?
After that, Xu Zhenming questioned Li Dayan's phone."Li Weiguo! What's the matter with Jinggong Electromechanical Engineering Company? Why do you want to make trouble at our construction site?" He asked with a cold face.
"Report to Mr. Xu! Jinggong Mechanical and Electrical Engineering Co., Ltd. is actually a subsidiary of Omori Jian'an Company. Crazy Zhang who is already inside is their big boss!" After a while, Li Dayan told Xu Zhenming of the heel of Jinggong Mechanical and Electrical Engineering Company on his mobile phone. .
After doing it for a long time, it turned out that Qi Linsen was secretly fighting against it.He was not too courageous. He set up a Seiko Electromechanical Company through a multi-registration model and secretly opposed Yang Ting's Chaoming Company.
interesting!
This shows that Qi Linsen has found a new backer, and the background is not small, not afraid of Yang Ting at all.Of course, he is not even afraid of Xu Zhenming, who has no background.If there was no Longbow Group's 1464 project, this person might have pointed his gun at Xu Zhenming.
Qi Linsen is also a billionaire, and he must have abundant contacts.It's just that this guy really shouldn't. He came to Xu Zhenming at such a moment. Isn't he hitting the gun?
Thinking of this, Xu Zhenming disregarded the rules and prepared to pull out the deeply hidden Qi Linsen.Ever since, he immediately called Gui Changshu, who was already on duty: "Leader Gui! It was Qi Linsen from Omori Jian'an that happened today!"
After saying this, he immediately hung up the phone and decided not to participate in this kind of affairs and let the Longbow Group and relevant departments handle it.
Sure enough, fifteen minutes later, he received a call from Captain Cha, stating that the project can be carried out normally and that it will be integrated into the post and telecommunications network tomorrow night.
Xu Zhenming only needs this result, nothing else will be involved.
Late at night the next day, around midnight.
Xu Zhenming, Zhang Guoli, Zuojian and others are already in the central computer room of Nan'an Post Office.
Fortunately, Xu Zhenming, don't participate in this kind of wiring, network data docking debugging, and writing of network protocol communication interface programs.
He also brought his laptop to work overtime, and at this time was revising the YMMCAD1.0 mechanical design software developed by Yiming Group.
The kernel code of this software was written by him alone, so it is very convenient to modify.Modify YMMCAD1.0's command name, shortcut key setting, drawing mode, mechanical drawing module component setting... etc. to AutoCAD mode, so that users do not feel unfamiliar.
At about two o'clock in the morning, Xu Zhenming had completed the revision of YMMCAD mechanical design software and determined the version number to be version 1.01.
At this time, Zhang Guoli's team has also completed its work, and the grid connection test is ready.
