What Zhang Dongsheng asked Zhou Yu to plan was none other than the future mobile phone factory after the GSM network was promoted.

If you want to develop high-precision electronics in future generations and develop civilian products, you will definitely be unable to do without the word mobile phone.

Of course, in this era they are called mobile phones, but they are actually the same thing.

As a top student, Zhou Yu made a simple plan, which was professional, not to mention that the question itself was not difficult.

After explaining the matter, it was getting dark, and Zhang Dongsheng went home from get off work.

I had a simple meal with Zhou Ying and went to bed. He was exhausted from the day. The two did not live together completely, but occasionally Zhou Ying would come over to stay a few times.

The relationship has developed to this point, and Zhou Ying has completely identified Zhang Dongsheng, so there is not much restraint between them.

But the last step has not been completely broken yet.

Maybe in later generations, having sex before marriage is not a big deal.

But in this era, it is a big deal. Which girl doesn’t want to save her first time until the wedding night?

Zhang Dongsheng could understand Zhou Ying's thoughts, so he was not too impatient.

Sooner or later, it is your own flesh, so why should you care too much about the length of time?

Although Zhang Dongsheng was also single in his previous life, it does not mean that he has not had this experience.

The early morning sun shone down, and the two people opened their eyes at the same time, as if they had a telepathic connection.

Looking at the beauty in his arms and her face that could be broken by a bullet, Zhang Dongsheng couldn't help but lightly scratch her little nose.

"Little girl, just wait. I will make a gift for you after a while."

"Um?"

Hearing Zhang Dongsheng's words, Zhou Ying was slightly startled, with a look of interest on his face. He was curious about what Zhang Dongsheng would give him.

They really know each other too well. Although Zhang Dongsheng is not a straight man, he is not a person who will please girls.

The two of them have been together for so long, and it's been a long time since he gave me anything as a gift. The only thing worth mentioning is the Xuyang game console.

But now that the Xuyang game console has been turned into an industry by him, Zhou Ying is also a bit dumbfounded.

Therefore, Zhang Dongsheng took the initiative to bring up this matter, which made Zhou Ying a little happy and not without expectations.

With a happy mood, Zhang Dongsheng came to the company. After briefly handling the affairs, he dived into the laboratory.

But what I started working on today is no longer a CPU processor, but a real GSM mobile phone.

The technology and functions here are actually not particularly complicated, and are even simpler for Zhang Dongsheng than the current simulator.

If all the parts and equipment are complete, he can assemble his own GSM mobile phone in two hours. Of course, the technology used may not be his.

But so what, the time is now 1992, and all technologies have not been invented yet. As long as Zhang Dongsheng can use it, it is his own.

Although it is said that almost nothing starts from scratch, Zhang Dongsheng is confident that it will not take long to create the first mobile phone.

The white paper was being written, drawn, and modified in Zhang Dongsheng's hands, and under Li Jun's confused eyes, the content on the paper gradually became fuller, revealing something very complicated to him.

However, although it is complicated, Li Jun can still roughly understand it. This should be a mobile phone, although he still doesn't understand how it is made and what the principle is.

Holding the blueprint given to him by Zhang Dongsheng, Li Jun felt as if he had found a treasure. In fact, many science and technologies are just like a layer of window paper. If you can't think of it, you can't do it. Once you see it and think about it, you may understand it at a glance.

.

This is the case for Li Jun now. When he saw this drawing, the most surprising thing in his heart was: So it can still be like this.

"We can't just look at the drawings. The two of us have to make the things on the drawings as quickly as possible, and then check to see if there are any shortcomings so that we can apply for a patent."

Zhang Dongsheng's mobile phone was all made by himself from design to research and development. It's just that he designed this plan not now, but in later generations.

It's just that making a gsm 2g mobile phone was really not a big deal in that era. When Zhang Dongsheng designed this plan, it was just out of interest, and he never expected that it would be used today.

It eliminates some things that are still beyond the reach of today's technology, such as cameras, Java games, etc.

Taking it out as a whole, Zhang Dongsheng looked at the final product on the drawing in a daze, because this thing was really familiar.

Long shape, simple design, and a small color screen.

The overall look is very similar to the Nokia c1 series that Zhang Dongsheng used when he was a child in his previous life.

There is no flip-up dust cover that often appeared on mobile phones during this period, and there is no extended antenna.

"This is a mobile phone? We already have the conditions to produce mobile phones? But I think this is different from the mobile phone we use!"

Regarding Li Jun's words, Zhang Dongsheng smiled and explained to him what the GSM system was.

The second generation mobile phones based on this system are of course different from mobile phones.

It is precisely because of the birth of the GSM system that the data transmission of mobile phones has evolved from current simulation to the digital era, and all communication facilities in later generations have a foundation to survive.

In many science fiction movies of later generations, the form used to express data flow is energy composed of countless numbers. The inspiration and information may come from this technology.

Li Jun is also an otaku who is obsessed with technology. He got this blueprint from Zhang Dongsheng and plunged into the laboratory without saying a word.

Without considering technology or doing research, it is not too difficult for researchers to hand-produce such a sample.

Within two weeks, Zhang Dongsheng had already obtained two GSM mobile phones, one black and one white.

It's just that China's three major operators have not yet started operation, and the gsm base station has not been officially established.

Zhang Dongsheng didn't even have an official phone card. So to achieve the purpose of calling, he could only set up a temporary GSM base station.

When the phone call between the two mobile phones was connected through the temporary base station and they could talk to each other, the entire Xurisheng laboratory was completely boiling at this moment.

Although Zhang Dongsheng's development of GSM mobile phone was not widely publicized, it was not deliberately kept secret either.
