Military Industry of Great Powers: Build the Strongest Flanker

Zhao Sanwan has attracted great attention from the public. In an era when most people's annual income is only more than 1,000 yuan, the impact of more than 30,000 yuan a year is still huge. Moreover, under the rhythm of many media, the finger is directly pointed at Zhao Guoqing.

Teacher Xiao Zhao can't control public opinion, so just make trouble if you like. In the 101 conference room, Zhao Guoqing warmly received the representatives of Huaneng Company.

Comrade Zheng Fei, who is in his forties, is not tall and always has a faint smile, which is impressive.

Zhao Guoqing got straight to the point and said: "Is Huaneng going to build a mobile base station?"

Zheng Fei nodded and said: "We hope to cooperate with Xineng Processing Factory to help us OEM RF, decoding, control and other chips!"

Zhao Guoqing nodded and said: "There is no problem with foundry chips, but I suggest you stop focusing on AMPS/TACS standard mobile analog base stations. There is no future!"

"..."

Zheng Fei's face was very ugly. Huaneng had spent more than three million on the research of mobile analog base stations. For this purpose, it also bought an Ericsson RBS883 analog base station.

"Director Zhao, what do you mean?"

Zhao Guoqing brought a piece of paper, and Zheng Fei and others gathered around.

Director Xiao Zhao drew the antenna feeder, analog unit, signal amplification, and loop transmission.

"This is the system diagram of our simulated base station?"

Zhao Guoqing nodded and continued to draw the second picture. This time the structure was completely different. It was divided into antenna feeders, combining and branching units, transceiver carrier frequency units and public units...

Zheng Fei quickly saw that the difference from the first picture was that this picture added analog signals to digital signals and digital signal processing and transmission units.

"this……"

Zhao Guoqing said: "You should have seen the news. We have made a breakthrough in optical fiber transmission signals. A single-mode optical fiber can transmit millions of telephones through composite wave transmission..."

Zheng Fei was horrified and said: "Director Zhao, are you saying that our cellular wireless phones will not use analog signal transmission in the future, but will all use digital signal transmission?"

Zhao Guoqing neither affirmed nor denied, and continued to draw the third picture.

This time there is not one base station diagram, but several base stations connected through optical fibers...

"Hey, no, this is not a complete base station."

In the picture, there are only transceiver units and analog-to-digital signal units. Dozens of base stations are connected through optical fibers to uniformly send data to the data processing transceiver units originally installed on the base stations..."

"Director Zhao, this..."

This picture completely overturned Zheng Fei's concept. He never expected that a base station could be designed like this. He saw the advantages of this model at a glance. Huaneng calculated that the price of a base station's signal processing unit accounts for 80% of the entire base station.

Now the signal processing units of dozens of base stations are merged into one and processed through optical fiber connection. If fifty are merged into one, the price of the network will be several times cheaper than the original base station. This is for the operating company. The value is too great...

"Director Zhao, does Institute 101 also want to build a mobile base station?"

Zheng Feiyou was a little desperate. Not to mention the strong technical strength of 101, Huaneng had nothing to fight with just these few pictures.

Zhao Guoqing shook his head and said, "Mr. Zheng, you only saw the surface, and there are things you didn't see."

"...Director Zhao, tell me!"

Zheng Fei looked at Zhao Guoqing like a god, and Zhao Guoqing also shook his head. Huaneng originally represented Siemens program-controlled telephone exchanges and got the first pot of gold. Later, it developed its own program-controlled exchanges and finally came to prominence.

The program-controlled telephone exchange of Institute 101 almost caused Huaneng to die prematurely, but fortunately, God had its own providence. Due to a combination of circumstances, Huaneng actually made its first pot of gold overseas by acting as an agent for Datacom's exchangers.

"The current analog signal base stations mainly use AMPS/TACS standards, and there are hundreds of standards around the world. These standards are undoubtedly implemented by hardware!"

For example, the wavelength used for signal transmission is about 800~900mhz, the standards of carrier signals are also different, the format encapsulation of voice information is also different, and the corresponding transmission response rules are also different.

These complicated standards have brought great historical burdens to base station design. Especially in the 2g era, the GSM/CDMA debate has almost reached the point where there is you without me, and there is me without you. And if the base station wants to fully support these standards, It is necessary to design a huge hardware scale, which is one of the reasons why analog signal base stations often have particularly large equipment.

Zhao Guoqing looked at Zheng Fei and said: "We can use software to simulate the hardware standard..."

"Use software to simulate hardware standards?" Zheng Fei was stunned.

Teacher Xiao Zhao described the entire technical route from 1g to 2g to 3g and 4g using software to simulate hardware standards.

Twenty years later, mobile networks have developed countless technical routes from 1g to 2g. By 3g, the industry has adopted CDMA technology as the mainstream technology of 3G. The ITU has determined three wireless interface standards, namely CDMA2000 and WCDMA. ,TD-SCDMA.

At that time, Huawei proposed the concept of using software to simulate hardware and produced finished base stations, which greatly reduced operators' construction costs for base stations. In a very short period of time, it defeated Ericsson and other giants in the international market. The falling flowers and flowing water...

Now, when Huaneng is just planning to enter the field of mobile base stations, Teacher Xiao Zhao's words are like pointing out a bright road for Zheng Fei.

If you follow this path, you will be far ahead. As for the route from 3g to 4g and then to 5g, Zheng Fei will definitely do better than him.

"Director Zhao, do you want Huaneng to give up the base station business?"

Zheng Fei shook his head, very unwilling. Just when he felt that he was in conflict with 101, he heard Zhao Guoqing say: "Mr. Zheng, 101 plans to include Huaneng in the cooperation list."

“101 still has a lot of accumulated technologies in wireless antennas, wireless data link transmission, microelectronic information processing and ADC/DAC chips. We are willing to license these technologies to Huaneng and send out technical backbones to help you with research and development. "

How can it be? Pie in the sky, Zheng Fei's head was dizzy. Under the great joy, he tried to keep a clear mind and said: "Director Zhao, what does Huaneng need to pay? I don't understand, if the 101 Institute comes to develop , will be better developed than Huaneng. Regardless of equipment or technology, Huaneng can only be said to be a guerrilla!"

Zhao Guoqing shook his head. Although the technology of Institute 101 was strong, it lacked a strong energy. Since he was in Institute 101, there would definitely be no problems with research and development, but what if he was no longer the director of Institute 101? Will this trend continue?

Zhao Guoqing doesn't know...

He now feels more and more that perhaps the director of Institute 101 will not be able to work for long.

Zhao Guoqing stood up, shook hands with Zheng Fei tightly, and said: "101 has funded many companies, but I didn't ask for any other requirements. I can understand your emotion of starting a business. If you keep going, I hope you can make Hua Hua a better place." Be strong, be the strongest in the world..."

"..."

"Director Zhao, thank you!"

Zhao Guoqing said: "Mr. Zheng, stay a few more days and I will find a few technical backbones for you. You can meet them first then!"

Zheng Fei nodded!

After Zheng Fei left, Zhou Li saw that Director Zhao was silent and stared at his notebook for a long time. He said with some worry: "Director Zhao, do you want to say hello to the leaders of Hui Province and ask them to come forward to coordinate these things?" What the media says is getting more and more outrageous!"
