1991 Starting from the core

Tian Yaoming continued with emotion: "You said that China has not yet considered using any network. This reminds me of the YD9100 that just passed the verification a while ago - you said that four such awesome institutions actually spent two years to develop Big Brother. . And the Ministry of Posts and Telecommunications actually supports mass production, which is really baffling."

Su Yuanshan said with a smile: "The country is not like us who can gamble. At present, it is understandable that the four universities choose to follow the trend and develop mobile phones."

The full name of the four institutes mentioned by Tian Yaoming is the Fourth Research Institute of the Ministry of Posts and Telecommunications, and YD9100 is an analog phone started early last year, which is also commonly known as domestic mobile phone. Since there is a ready-made network in the country and the market expectations are clear, the progress is very fast. In May this year, it officially passed the acceptance of the Ministry of Posts and Telecommunications. It is said that a company has been established and is engaged in mass production in Jiangyin.

Because it was developed by a research institute affiliated to the Ministry of Posts and Telecommunications, it still has a certain market and support. Due to the interests, it is difficult to say whether the establishment of a GSM network pilot in Guangdong Province two years later has anything to do with it.

This is why Su Yuanshan has always told Tian Yaoming not to worry - except for Yuanxin, no company currently values ​​the current domestic market.

How do you say you can appreciate a country's market? Of course, it is the first time to launch products in the native language of that country.

Starting from mobile phones, to pagers, and even early feature phones, there was no Chinese language - it was not until 2000 that the first Motorola CD928+ that supported all Chinese appeared.

All Chinese means that the menu, text messages, and address book are all Chinese characters.

As a domestic company, Yuanxin will of course release a Chinese phone.

Therefore, Su Yuanshan only provided Tian Yaoming with unconstrained and unconditional support for three years last year.

I just didn't expect Tian Yaoming to be so eager. He probably watched Yuanxin grow into a giant just like spreading pancakes, but he was a bit conceited when he couldn't produce any results.

"Anyway, don't worry, the operating system and input method have to keep up, and there are various mold considerations and compromises later - we have time." Su Yuanshan continued to calm Tian Yaoming's mind.

"Okay. I'm going to get this text messaging system. You go tell your dad and ask him to ask the School of Mathematics for help."

Su Yuanshan smiled and shook his head: "It's better for you to go, so you can explain your project clearly."

"Okay, I'll go to Beijing Postal Service at the end of the year to see if I can get some people to come over."

…

Watching Tian Yaoming go out in a hurry, Su Yuanshan returned to his seat.

In order not to overly stimulate Tian Yaoming, he did not tell the other party that in addition to Nokia, Siemens and Motorola would launch GSM mobile phones at the same time within six months. According to the current progress of Yuanxin and Xinghai, it will be considered fast to launch by the end of next year.

At the same time, the future battle for network standards is also beginning to take shape in the current 2G era.

In addition to GSM, IDEN, D-AMPS, and IS-95, also known as CDMAone, developed by Qualcomm, they all have their own markets, but in the end, GSM dominates the world - except for Ni Guo, who has great ideas, they have created a set of their own called PDC standards.

(Omit the description of the three standard address classifications, see the notes in this chapter for details)

But after the arrival of the 3G standard, there were only three standards left: CDMA2000 upgraded from CDMAIS95, WCDMA upgraded from GSM, and TD-SCDMA proposed by the country - they all adopted CDMA code division multiple access technology. .

Of course, just like the 2G era, there is also a very thoughtful player in the 3G era - Intel only proposed the wimax standard when people were considering moving to the 4G era, but it naturally ended in nothing.

Among them, WCDMA and CDMA2000 are adopted by China Unicom and China Telecom respectively.

TD-SCDMA was adopted by China Mobile, and to distinguish it, it was called G3.

As for why TD-SCDMA was given to China Mobile, which has a deep user base, it is entirely because it is a domestically proposed standard, and in a sense, it is "independent research and development."

But in fact, it was an "abandoned baby" bought from Siemens by Datang Telecom, an affiliate of the Telecommunications Science and Technology Research Institute of the Ministry of Posts and Telecommunications mentioned earlier. Whether it is technology or chip baseband, the support it receives is very imperfect.

So you can imagine how frustrated the G3 was for Mobile back then.

And because Qualcomm has an absolute monopoly on Telecom's CDMA2000 and adopts a complete machine licensing solution, future telecom mobile phones will be inexplicably more expensive.

But now, everything is still in the ascendant. As Su Yuanshan said, if you have time, don’t be in a hurry.

Although Yuanxin lags behind in 2G, it will start to develop CDMA-based patents from now on, so it can still follow Qualcomm in the 3G era.

When Qualcomm attracts all the firepower and causes "Qualcomm has been suffering all over the world for a long time", it will not be too late for Yuanxin to follow a group of European buddies to establish 3GPP and start working on LTE (4G). By then, this patent blood-sucking maniac will be completely eliminated. life.

LTE, translated as long-term evolution technology (for existing communication technology) - listen, this is the name given by a bunch of Qualcomm brothers in later generations to fool the operators, which means that we are just upgrading and evolving the current technology. . He was so cautious and shy, for fear of making the operator unhappy.

You must know that operators spend a lot of money on base stations. Your 3GPP has a new standard in two years. So you will pay for the replacement of base station equipment?

…

As the first sycamore leaves fall, autumn has officially arrived in the provincial capital.

During the National Day, "Spring Story" invested by Yuanxin officially passed the review and was sold to the TV station at a friendly price.

The reason why it went so smoothly is entirely because its content is positive and healthy, closely follows the wave of reform, and has pioneering significance. Even if it is suspected of advertising Yuanxin, there is no mention of Yuanxin in it, so it cannot be considered brand placement.

What was also sent to the review office was a brand new VCD prototype without a logo in addition to the CD. It can be said that the person responsible for reviewing the film completed the review under surprise throughout the entire process.

At the same time, the first production line of the VCD factory also achieved mass production just in time. We are currently ramping up production at a rate of 500 units per day, and we are waiting for the moment when the TV series is broadcast.

And in the end, Su Yuanshan did not skimp on advertising fees. He was still planning to do a wave of publicity in conjunction with the broadcast of the TV series. And if the production ramps up smoothly, he also plans to spend some money to remove Seagull Watch from its position as a sponsor of the Spring Festival Gala.

…

After the three-day National Day holiday, Qu Hui and her people withdrew from Chengguang Institute.

"The hill is not easy to clean up."

Qu Hui's hair is a little longer, but it's still cool. Sitting in Su Yuanshan's office, she took off her glasses and wiped them while saying: "Huajing's engineers have been working on it for a month, and the yield rate is almost 30 to 40% at 2 microns, which can be barely used. As for you Don’t even think about it when it comes to multiple exposures, I don’t have any technical reserves.”

Su Yuanshan sighed in his heart, and it turned out to be just what he had learned on paper. But he still smiled and said: "It's fine for self-research. What's the problem?"

"Workpiece table." Qu Hui put on her glasses and smiled helplessly: "There are only two keys to the alignment system, one is the focus and the other is the workpiece table. Let's put it this way, if we hadn't gone there this time. This photolithography machine I'll eat the computer when the function starts to work! Oh... I guess it can be done by manually adjusting the focus a few hundred times."

"puff……"

Qu Hui said: "The main reason is that there is a problem with the design of the workpiece table itself. There are no professional workpiece table companies in China."

Su Yuanshan nodded: "A high-precision workpiece table requires a high-precision machine tool."

"Well, so I have an idea, let's just make a set of CNC programs." Qu Hui stared at Su Yuanshan, pursed her lips, and slightly raised the corners of her lips: "After working on PLC for a while, I suddenly found that machinery is quite interesting. I'm going to study it. On-the-job PhD in Mechanical Engineering.”

Su Yuanshan looked at her in surprise.

"real or fake?"

"Really, domestic machinery has a bright future. Besides, I'm not screwing screws. I'm mainly interested in mechanical design and automation."

"Okay, I support you." Su Yuanshan promised neatly.

Qu Hui clenched her fist and said boldly: "Then it's settled happily!"

Su Yuanshan smiled and nodded.

He really had no intention of throwing away the machinery-related aspect—because he had a lot of fights with several parties not long ago.

According to the requirements of Erzhong, Shengfei and Jiangzhou, the design CAD developed by Yuanxin for them is proprietary. But as their requests became more and more complex, Zhu Jianting became a little impatient.

So Su Yuanshan discussed with these parties and re-signed the contract. Mechanical CAD is transformed into a business model, promoted and maintained by Yuanxin, so that it has the potential for sustainable customer development.

However, several parties thought that this was a collection of various needs and ideas that gathered the wisdom and hard work of those veteran engineers, and just gave it to Yuanxin in vain, without even thinking about it! Even though Yuanxin promised to provide consultant subsidies to the engineers, it was unwilling to let go.

In the end, Su Yuanshan was really at a loss, so he took out the contract signed by both parties and reviewed the projects one by one according to the terms - for example, the contract only required the ABCDE function, but Yuanxin has now developed it to M...

Once this contract comes out, no matter how shameless Party A is, it’s hard to say anything. You can’t lie and say you remove redundant functions. I want this.

In the end, the lawsuit was brought to the ministry, which ultimately allowed several parties to choose to make mechanical CAD a commercial software based on the overall situation of benefiting the entire domestic machinery industry, and at the same time, Yuanxin also gave these parties preferential treatment.

Of course the result is pretty satisfactory.

After sending Qu Hui away, the phone rang immediately.

Qin Weimin's long-lost voice came from the microphone.

"Xiaoshan, I'm going to come back tomorrow and bring you a gift."

"what gift?"

"Haha, it's from Sony." Qin Weimin smiled on the phone and said with emotion: "As expected of Sony."
