After Tao Guangming brought the contract to Suicheng, a few days later, Jiang Changhang called to discuss a few details and basically finalized the content of the agreement. In fact, there were very few technical issues, and most of them were about financial equipment.
bargain.
Suicheng wanted Li Wenjun to support him more, but Li Wenjun was not that stupid.
Finally, a balance point acceptable to both sides was found.
Jiang Changhang asked: "When can Li Wenjun come to Suicheng? If you find it troublesome to come, I can ask someone to drive to pick you up."
Li Wenjun kept muttering in his heart: Suicheng was too anxious, and why did he insist on getting him to sign the agreement?
He pursed his lips and said nothing.
Jiang Changhang said: "We want to put the base station into trial operation during the Spring Festival. Because during the Spring Festival, many people return to Guicheng from Hong Kong and Macao, and many people use mobile phones."
Li Wenjun suddenly realized.
Mobile phones are relatively expensive, and it is impossible to send out prototypes for testing like pagers. If the number is not enough and the distribution is not enough, it is impossible to ensure that the blind spots covered by all base stations can be discovered.
Li Wenjun thought for a while and said, "I'll come over this weekend."
Jiang Changhang said: "Comrade Li Wenjun is here, and he may want to popularize the knowledge of wireless communications to the comrades here."
Li Wenjun understood instantly: signing the agreement was one thing, but the main reason was to see if he understood it.
In their opinion, there is still a long way to go between pagers and mobile phones. It is not safe to hand such a large project to a young man in his early twenties as the technical director.
Jiang Changhang needed Li Wenjun to convince others for him. After all, he himself was very young.
Li Wenjun smiled: "Okay. I just used these few days to get a piece of information out, and I will show it to the leaders then."
This matter must be done sooner or later. In fact, when Li Wenjun made the first batch of mobile phones, he had already started writing this thing. During this period, he also asked Gu Zhanyan to help modify the wording and English annotation.
Jiang Changhang: "I will send a car to pick you up and help you arrange a hotel."

The day after Li Wenjun arrived in Suicheng, Jiang Changhang organized a small meeting.
It is said to be a meeting, but in fact, Li Wenjun speaks first, everyone listens, and then everyone asks questions, and Li Wenjun answers.
What most people don’t understand about wireless communications is: without wires, how can you make calls wherever you go? How can that sound be transmitted?
Therefore, Li Wenjun focused on the issues of cellular coverage and automatic switching between base stations.
Someone asked Li Wenjun what is the difference between the base station used for pagers and the base station used for mobile phones.
Li Wenjun patiently explained that one of the two things only transmits a few words and symbols, while the other ensures that the sound can be transmitted accurately in both directions. The data transmitted is not of the same level.
In fact, the base station is only a very small part of the entire wireless communication system. In addition to the base station, there are also switches, location registers, and a central database.
Therefore, in addition to having a stronger signal, the mobile phone base station must also be able to transmit large amounts of data. It also requires higher central processing data processing capabilities and security.
Someone else asked, how can we ensure wireless communication between cities when the base stations are so far apart?
Li Wenjun explained that long-distance data transmission relies on cables to be transmitted from one city to another, and then converted into wireless propagation signals, which are spread out by base stations.
Li Wenjun only spoke for twenty minutes during the entire process, but answered questions for almost two hours.
Jiang Changhang did not tell Li Wenjun that in fact, those who came to listen today were not only leaders and technical personnel from relevant departments, but also five experts they specially invited from Hong Kong City, Suicheng City and Beijing City.
Just now, it was mainly these experts who asked questions, in order to test Li Wenjun's professional ability.
So the questions asked are relatively professional.
It doesn’t matter if others seem to understand but not understand. The most important thing is to dispel their suspicions about Li Wenjun.
Li Wenjun was recommended by him, and he also wanted a team of experts to help him check it.

After the meeting, the experts stood up and came over to shake hands with Li Wenjun.
Expert A: "When we were building pager base stations, we had already heard about Comrade Li Wenjun. I didn't expect that Comrade Li Wenjun would start building a mobile phone communication system so soon."
Li Wenjun actually figured out the origins of these people because ordinary technicians couldn't ask such questions.
He answered humbly: "It's mainly the leadership's support and the ability to build the team. I just provided a little technical and financial support."
Expert B said: "I hope Comrade Li Wenjun can successfully build it in Suicheng as soon as possible and then roll it out in Haicheng. When the time comes, Haicheng will also ask Comrade Wenjun to support it."
Li Wenjun smiled: "If there is a need, of course I will do it."
What I was thinking in my mind was: Everyone wants to cut my flesh off, and they say so in a high-sounding way.
After everyone dispersed, Jiang Changhang took Li Wenjun to the office next door to sign the agreement.
Jiang Changhang asked: "When will the equipment needed for the base station be delivered?"
Li Wenjun said: "In the middle of the month, in fact, after you finished telling me, the factory has already started production."
Now the production efficiency and level of "Wenjun Industrial" have been greatly improved compared to when they were making base stations for pagers. He doesn't need to bring a few more masters to do it.
As he kept pushing forward, even Director Cai's technical level continued to improve.
As long as he made a request, Director Cai would quickly prepare new components and send them over.
Then Wenjun Electronics Factory made things according to Li Wenjun's drawings.
And his drawings have been drawn a long time ago. Mainly because he is afraid that he will forget them after a long time.
Jiang Changhang smiled happily: "Comrade Li Wenjun's efficiency is really high. I really didn't choose the wrong person."
Li Wenjun smiled: "Thank you for your trust, leader." His guess was correct. It was indeed Jiang Changhang who recommended him.
But think about it, looking across the country, there are really not many people with better technical skills and a lot of practical experience than him.
Who wants him to have technology reserves that are forty years ahead of his time?

Li Wenjun came out of Jiang Changhang's place and went straight to the exhibition hall that Tao Guangming had opened.
Tao Guangming is not good at anything else, but his vision for choosing showrooms and stores is first-rate.
The locations he chose in each city will be the city's absolute commercial center in the next few decades.
This is all due to the acumen developed through a long-term love of eating melons and watching the excitement, as well as the well-informed sources of information.
After all, knowing the urban planning for the next ten or even twenty years is a better vision than anything else.
The exhibition hall in Suicheng is located in a place that is not very busy now, but will be very prosperous in a few years.
Tao Guangming rented a corner location according to Li Wenjun's design, and both floors were covered with large floor-to-ceiling glass windows.
A one-to-one wooden car model that Li Wenjun asked a furniture factory to imitate was glued vertically to one of the exterior walls.
