The technological flood of rebirth

Chapter 35: Research and development of 2G technology

After the communication company completed the test of Wanmen digital program-controlled switches, it sent the relevant report to the Ministry of Posts and Telecommunications. When the Minister of Posts and Telecommunications received the report from the communications company, he initially thought it was a scam, and then asked the people below if anyone knew about Hengtong Communications Company.

Not to mention, some people really know this question, because the communications company has been poaching people aggressively and has a love-hate relationship with many units of the Ministry of Posts and Telecommunications.

When asked to find out that such a communications company does exist and that the owner is still Zhao Yi, the minister became a little convinced, because Zhao Yi could not deceive the post and telecommunications department. He had no such motive, and his semiconductor company had just made a shocking move. The results force people to take his business seriously.

So not long after, an inspection team composed of leaders and experts from the Ministry of Posts and Telecommunications came to the communications company, and Hou Weigui warmly received them.

After a while of greetings, Hou Weigui asked the technicians to use the previous test environment and demonstrated it to the inspectors on site. The result is very good, and it is already superior to foreign products among similar products.

After the inspection team returned with the results, the entire Ministry of Posts and Telecommunications was in a sensation. Even the minister himself said: "This will open a new chapter in my country's communications industry."

Since it was a product of a domestic company, foreign exchange was not required for purchase, so the Ministry of Posts and Telecommunications soon sent people over to discuss cooperation with the communications company.

Nowadays, a telephone exchange in the world costs 200 US dollars, while the one sold to our country in the 1980s cost more than 300 US dollars. But there is no way. If we don’t master the technology, we will have to be ripped off, and then the people across the country will foot the bill.

After several rounds of negotiations with the post and telecommunications department, the communications company signed a cooperation agreement with the post and telecommunications department at a price of 300 yuan per door.

This price seems to be 200 US dollars per door according to the current exchange rate. The current exchange rate of USD to RMB is 1.5. But you must know that the actual use of US dollars and RMB is very different.

At this price, if ordinary people install telephones, a phone will cost no more than 500 yuan. Although this is still very expensive for many people, it is not out of reach.

The current constraint for communication companies is production capacity. Currently, there are only about 400,000 production lines under construction, while the post and telecommunications department has placed orders for 2 million units this year, and there will be more and more in the future, so it is imperative to expand production capacity.

Just when the communication company was full of joy, Zhao Yi came to the communication company and discussed with Hou Weigui the future development of the company.

It was said to be a discussion, but in fact most of it was said by Zhao Yi. This time Zhao Yi initially asked communication companies to research and develop 2G technology. Currently, 1G is still prevalent internationally. Motorola's boss is probably familiar to everyone who has seen Laogang, and he uses 1G technology, which is an analog signal.

1G technology has obvious shortcomings: first, it has poor confidentiality and is easy to be eavesdropped; second, the system capacity is small, which will result in high communication rates and a limited market; third, the terminal function is weak and has no other functions except making phone calls. .

In addition, 1G technology is basically monopolized by Motorola. It is impossible for Zhao Yi to develop another 1G technology and pay Motorola patent fees.

The future 2G technology can basically be divided into two types, one is developed based on TDMA (Time Division Multiple Access), represented by G**; the other is CDMA (Code Division Multiple Access) specifications, later Qualcomm That's it.

As for FMDA (Frequency Division Multiple Access), it is already used in 1G technology, so Zhao Yi will not devote major energy to research and development in this regard.

Currently, no one in the world has increased investment in research and development of 2G. This is exactly what Zhao Yi wants. If you develop all 2G technologies yourself and apply for patents, it will be impossible for foreign countries to leave you and go it alone. In the future, whether you collect patent fees or sell equipment directly, it will be a very satisfying thing.

So the communication company established two new departments, one responsible for the research and development of TDMA technology, and the other responsible for the research and development of CDMA technology.

Then Zhao Yi conducted technical training for the technical staff of the two departments and left a full set of technical information for them to develop related products based on the technical information.

As for the original switch R&D department, in addition to continuing to upgrade research and development in the field of digital program-controlled switches, it also needs to conduct research and development of basic Internet technologies.

In Zhao Yi's plan, communications companies will be able to come up with a set of leading international solutions, whether in the field of telephone communications or future network communications, and capture most of the cake in the future communications field.

This busy time quietly came to September, and Zhao Yi finally broke away from these company affairs and stayed alone in Prince Gong's Mansion, fishing and raising flowers, and living a rare leisurely life.

"Zhao Yi, if you are in charge of baking this time, I will tell you a little secret." Zhou Jinyu said to Zhao Yi mysteriously.

The other two people also looked at Zhou Jinyu together.

"I'm not interested. I won't bake this time. Why do I do it every time?" Zhao Yi was too lazy to talk to Zhou Jinyu and wanted to change his destiny as a cook.

"If you don't want to bake it, I won't say anything." Zhou Jinyu was quite stubborn.

When the other two people saw this, they encouraged Zhao Yi to come to the barbecue. They could persuade Zhao Yi in just a few words, just one sentence, "It's impossible, otherwise everyone won't eat."

Among the four, Zhao Yi has the best barbecue skills, and the others can reach the level of cooking. In order to satisfy his own appetite, he can't prevent himself from using various methods to get in and out.

After a fight, Zhao Yi was defeated. He honestly picked up the grill and brush, sat beside the oven and started cooking.

When everyone had finished drinking and eating, they all looked at Zhou Jinyu, meaning that this should be said.

"The secret is that Zhou Jinjue fell in love at school." Zhou Jinyu wiped her mouth and said with a smile.

Zhou Jinjue, who was on the sidelines, did not expect that her sister would betray herself, and quickly argued: "I didn't, don't lie."

"Last time I went to your school to look for you, I saw you and a girl holding the same umbrella. Is this the case?" Zhou Jinyu said, presenting the facts.

"That's because the school girl forgot to bring an umbrella when it rained." Zhou Jinjue explained.

"Oh..." the three of them mocked.

"Whether you believe it or not, I believe it anyway." Zhou Jinjue was also very single.

Zhou Jinyu and Lin Hexia, on the other hand, were making insinuations, asking how old the girl was, what her name was, and where she came from.

Faced with three consecutive questions from her aunt, Zhou Jinjue remained tight-lipped and said she didn't know. Everyone had no idea, so they punished him to clean up after the meal.

After dinner, Zhao Yi and Zhou Jinjue went to the back garden to fish, while Zhou Jinyu placed a guzheng in the pavilion and started playing it, while Lin Hexia read a book aside.

While fishing with Zhou Jinjue, Zhao Yi tested Zhou Jinjue several times, but still found nothing. This gave him a new understanding of Zhou Jinjue's ability to keep secrets.

It's a tough one.

While Zhao Yi was enjoying this leisure time, the upper management started a discussion on the issue of employment for educated youth returning home. (End of chapter)
