Although the situation in Bianliang is unpredictable, Qin Mu can't stay in Bianliang all the time. He must return to Wujiazhuang every seven days, and then go to the future to bring back the equipment he urgently needs.

This is also the most important thing - Qin Mu no longer knows what is really important, because there is nothing unimportant, all important.

But it's really important to go back and pull up the equipment. This time, Qin Mu brought back several sets of real standard communication systems: RASYS rural access solutions.

This system is also known as the wireless village network. It has all the advantages of CDMA, and because of the low frequency band, the coverage area is amazing, find the highest mountain and throw it on, and there are all tens of kilometers around.

Moreover, this system does not have core network equipment, and a set of virtual core network is built on CBSC, which has a simpler structure and is more suitable for regional layout. And the terminal is even more suitable, the terminal of this thing is a fixed line with an antenna, and it can be connected to an external Yagi antenna to enhance the signal in places with weak coverage. Although it is very earthy, it is really durable and extremely cheap.

The adoption of this system was in 04, and even later when the technology developed, it was proposed to keep it as a combat readiness network.

However, because the 450MHZ is a public frequency band, which is used by radar and disaster prevention and emergency communications, the location is awkward. However, this problem does not exist in this time and space, and there is no other semicolon in the world, so there is no conflict at all.

In terms of capacity, CDMA1X can support 57-58 users in a carrier frequency excluding overhead channel, and if you consider S2/2/2 dual-carrier frequency 3-sector sites, a station can support more than 300 users at the same time, and the actual number of users can be 2000-3000 considering the utilization rate.

The scale of less than 1,000 people can be done with a base station, which is too suitable for Qin Mu.

It's just that the trading of complete sets of telecommunications equipment requires a certain relationship, and it is definitely not possible to rely on Qin Mu, which is all thanks to Jinsha's wide relationship and big face, so he took great pains to get it.

This system was first installed in Wujiazhuang.

Qin Mu deliberately called Wu Xiaomei back and asked her to learn how to install and debug the system with her.

After a busy day, I finally succeeded.

At this time, Jia Hongxian, Zhe Meiluan, Jiang Yuenu, Yu Liyan, and Wu Xiaomei all gathered in the East Cross Courtyard and gathered around Qin Mu. My man is going to assign a number, which is a big deal, and you can't be sloppy.

They've all used radios, they've used military communications equipment, but that thing is different from a real telephone. That can be seen as a better hand, you speak, I listen, you listen, one person speaks, everyone listens.

After using it for a while, they all realized that this thing was not suitable for civilian use, but they couldn't find a replacement, so they always felt that it was not embarrassing.

But with this civilian telephone system, it's completely different. The man said that this was a one-on-one call, and the two of them talked, and no third person could hear it.

It's a great way to make a phone call - of course, they don't know how to make a phone call yet, but they will undoubtedly learn it later.

There is a number for each phone, and this number should be picked carefully.

First of all, there should be a telephone in the East Cross Courtyard, and this number is very important. This is the first phone number of the Great Song Dynasty, which is used by the future emperor, and it must be meaningful.

"Cousin, if you want me to say seven, it's just seven one." Jia Hongxian was the first to speak.

Although this set of equipment supports thousands of users at most, and a five-digit number is enough, Qin Mu thinks it is better to expand the capacity.

In more than ten years, it is obviously impossible for this time and space to develop to the level of the 21st century, with a mobile phone and a full eleven numbers, but if only five digits are used, it is a bit too short.

Therefore, Qin Mu set the phone number to seven digits, and the phone number is long, and the province dialed the wrong one.

"Red Line, you're a good idea. It's just a little bit of a problem, though. "Qin Mu knows what Jia Hongxian means, one is the boss, and seven is the big one. But this phone number can't be set like this: "Look, if we use this as a number, you can press it." ”

As he spoke, Qin Mu handed the phone to Jia Hongxian.

Jia Hongxian immediately pressed the one one again and again. It didn't take a few clicks for her to understand herself. This number is really not good.

Because when you press one, you have to remember how many times you press it. The subordinates pressed one, thinking about two, three, four, this is not good.

In fact, Qin Mu didn't think there was anything wrong with Seven One in his heart, but in his later life, he was used to the situation that the phone number was staggered and there was no one word, so he would not use Jia Hongxian's plan.

And there is another point to consider, which is that this phone number, preferably reflects the nature of the department. Anyway, now that the technology of this time and space is thousands of years ahead, there is no need to care about the confidentiality of the phone number, so it is better to make a small distinction in the number.

"Red line, let's use the first three digits of the phone number as the department code, and the last four digits as the actual number. So, let me give you an example. The phone at home is 100 for the first four digits and 9595 for the last four digits. ”

"Then our phone number is 1009595." Yu Liyan immediately understood.

"Yes." Qin Mu nodded and said: "Next is Meiluan's Ministry of Civil Affairs, the phone number starts with 200, Meiluan, you can choose the last four." ”

"Then I'll want 7777!" Zhe Meiluan immediately chose a number for herself: 2007777. I'm a wife.

"What about the Ministry of Education of the Moon Slave, let's start with 300."

"Then I'll want 7777 too." Jiang Yuenu didn't choose another number. So the phone from the Ministry of Education became 3007777.

Jiang Yuenu felt that her number was more meaningful than Sister Meiluan's. The 300 poems, the 300 articles of the Book of Songs, are the source of education. He is the source and the wife.

Jia Hongxian saw that this was not good, you are all seventy-seven-seventy-seven, and I have to ask for a seven-seven-seven-seven. Anyway, there are so many phones now, and I can count one in my bedroom.

"Cousin, I'm going to press one in the bedroom, 1007777. Good no good? "Jia Hongxian felt that he had to be bigger than others!

Qin Mu thought for a while and said, "Red line, what about this number, it is said to be good, but how much is a bit of a problem." What we just said is classified by department, it is a phone for doing business, at home, it is a private matter, it is best not to use such a beginning. I suggest that our personal phone numbers start with 666. ”

Lao Tie, 666. The live broadcasts of later generations were flooded, all of them were Lao Tie 666, which made Qin Mu feel very bored. So it's 666 for private matters.

"Okay, then the phone in my house is 6667777." Jia Hongxian finally grabbed a 7.

For more than half the night, Qin Mu's family spent this kind of discussion.

Qin Mu really didn't expect that there were already so many of his various departments.

For example, in the army, Qin Mu gave the beginning of 900. 100 is themselves, 900 is the army, and the middle is under the protection of themselves and the army.

Barracks, officers' quarters, gates, regimental headquarters, warehouses, and other departments are all equipped with telephones starting with 900.

As for whether the military academy belongs to the Ministry of Education or the army, Jia Hongxian and Jiang Yuenu argued for a long time. In Jiang Yuenu's view, education should start with 300 if education is to be unified.

But Jia Hongxian resolutely refused, how could everything be in your hands? Besides, the military school was originally in charge of me, and I was the principal of West Point.

In the end, Jia Hongxian still won, and the military school started with 900.

The struggle and compromise only made Qin Mu almost get under the bed. One number can cause so many troubles. If you arrange it yourself, you can solve the problem in one hour.

But this discussion is troublesome. In addition to the barracks, there are also various factories.

The entire industry was originally under the management of Zhemeiluan, so Zhemeiluan was ready to start with 400 to classify the industry. But later, there were more furniture factories, and the furniture factories were several supporting factories, which could be said to be a separate piece. This piece is under the management of Jia Honghong, Jia Hongxian should start with 666, she thinks this is best in the private category.

Because the furniture factory is a separate account, it is not in the public account of Zhemeiluan, it is a separate department.

Just for such a trivial matter, Qin Mu's family quarreled for most of the night, and in the end it was too late, they were afraid that Qin Mu's body would not be able to stand up, so they temporarily withdrew the troops and quarreled again tomorrow.

Early the next morning, Qin Mu ran away. Distribute how you like, I'll hide first.

He asked Wu Xiaomei to bring a set of systems back to Weishan Lake to install them. If there is something that will not be solved, wait for him to go over and solve it. And he took Yu Liyan back to Bianliang again, and also pulled four sets of wireless village network systems.

Back at Zhefu, Qin Mu immediately set up a communication system. This time, he fully learned the lessons of last night, and he didn't discuss it at all, and all the numbers were set by himself.

This system can completely cover the entire Bianliang City, so it is easy to communicate between Zhefu, Zhefu and Fanlou.

Mu Nanxing now has her own phone number, through which she can contact her lover at any time. Of course, this requires Qin Mu to be in his own bedroom in Zhefu - the phone is installed in his bedroom in Zhefu.

As a result, Qin Mu suddenly found that his time had become more scarce. The phone calls are non-stop every night, either he is looking for him, or Ringo is looking for him, of course, the most looking for him is Mu Nanxing, this woman doesn't stop calling as soon as she calls.

This made Qin Mu's limited rest time fragmented, so much so that Yu Liyan didn't agree anymore - this greatly exploited her time.

Qin Mu had to sigh that science and technology change life, and it was really not a lie.

This system is so magical that it makes the fold save like to jump.

That military communications equipment is very inconvenient to use, and it is impossible to talk about things at length. Now with this phone it's completely fine.

He immediately recognized the revolutionary use of telephones, so he immediately arranged for manpower to transport the remaining three sets to Xiahetao and install them in the three cities of Yongbyon.

I didn't even consider the state discount and deposit. Because he knew that it was the old city, that everything was old and that it did not fit into the new world.

The telephone is undoubtedly a symbol of the new world, and only the three cities of Yongbyon Riverside Dong Shengju should be used first, these three cities, completely according to the new design of my brother-in-law, are completely renovated, and only here do they need telephones.

That department, every factory, if you press the phone, do you still have to run around like a rabbit every day?

As long as you sit in the office, drink tea, and press a few numbers, you can find each person in charge, which greatly improves office efficiency.

Time is money, efficiency is life. Zhen Kecun realized this truth thousands of years in advance.

"Brother-in-law, this set of things will be able to be shipped to the place in a month, so you have to find time to go and install this first." Holding the phone in one hand and a cigarette in the other, Zhe Kecun sat on the sofa of the new model, knocked on Erlang's leg, and talked to Qin Mu across several yards.

"Don't worry," Qin Mu was talking to Zhe Kecun while pulling Yu Liyan to the side - this princess was not honest with herself for a moment: "What, it's quite late, I'll sleep first, talk another day, hang up." ”

Qin Mu didn't wait for the fold to save the call, and hurriedly hung up the phone.

Okay, it's twelve o'clock in the middle of the night, and it's really speechless to save and call.

Alas, although telephones began to appear in this time and space, it is obvious that the quality of survival has not caught up with the common people of later generations. Basic politeness must always be spoken, and you can't call people to harass people in the middle of the night.

"Sleep!" Qin Mu hurriedly turned off the lights.

"Brother-in-law, the slave wants to sleep with the light on!" Yu Liyan immediately turned on the light again.

What is the meaning of blind fire in the black light, you have to turn on the light, and your exquisite figure can be appreciated by your own men.

The princess of Liao is so uninhibited!
