Countercurrent 1982

Chapter 1287
Without any hesitation, Duan Yun directly asked the receptionist at the booth if he could purchase the source code of this audio software.

Although this software is not the final version of MP3, and the compression ratio is only 4:1, for Duan Yun, as long as he continues to develop according to this source code development model, he will be able to complete the final version of MP3 sooner or later.

The company exhibiting audio software is called Motion Graphics Experts Group.

The so-called "Motion Picture Experts Group", which was established in 1987, is committed to the development of video and audio compression coding technology. It is a branch of the International Standards Organization (ISO). Its headquarters is located in Geneva and is responsible for setting standards for various industries around the world. .

However, the answer Duan Yun received made him very disappointed. The research team was not planning to sell the patent, but was planning to seek cooperative manufacturers to promote the software.

In desperation, Duan Yun had no choice but to take away a software manual about this MPGE-1, and was going to take it back for research.

Later, Duan Yun visited the booths of some communication companies in the European exhibition area, including the latest products of companies such as Arbat and Ericsson.

Nowadays, mobile communication has become the key research and development direction of these international communication giants. Mobile phone base stations and satellite communication equipment have become popular products in the European exhibition area of ​​this year's exhibition. Many European technology companies are also seeking cooperation and development around these companies.

But in general, the mobile communication industry is still in its infancy, and it is not complicated in principle. The most important thing is how to find a good balance between product quality, performance and price, so as to establish a market Competitive Advantage.

From this point of view, European companies are the strongest. In fact, American and Japanese multinational giants should also have strong technology and can develop communication products with high commercial potential. However, due to their own technology The trees are different, and each has its own focus. The US high-tech industry mainly revolves around PCs, while Japan focuses on game consoles and various household appliances. Europe, which has invested most of its financial resources and manpower in the communication industry, undoubtedly has an advantage in this field. strong advantage.

In fact, at the earliest time, the United States was the overlord of mobile communications.

Wireless communication is mainly used in the national aerospace and defense industry, with military color.We often see the 15-kilogram thing on the back of American signal soldiers in World War II movies, which is the first generation of cross-generation wireless communication product SCR-300 developed by Motorola.

Until 1973, Motorola engineer Martin Cooper invented the world's first mobile phone - the mobile phone.The mobile phone was built, and the transmission was done using the cellular network, also known as the mobile network.

It can be said that the king of the 1G era is none other than Motorola. It not only monopolizes the mobile phone market in the global siege, but also is an equipment supplier of the AMPS system. More than 70 countries around the world apply the AMPS standard.This also means that the United States firmly holds the first-generation mobile communication standards in its hands.

The mobile phone that Duan Yun is using now is a Motorola product.

In the 2G era, American CDMA lost to European TDMA, which indirectly became the starting point for Motorola to fall from the altar.

In the 80s, European countries reached a consensus on TDMA, and the next step was to discuss standards. At this time, European countries learned the lessons of failure in the 1G era. In 1982, the European Union jointly established GSM (Global System for Mobile communications) to be responsible for the research of communication standards. , Telecom giants such as Ericsson, Nokia, Siemens and Alcatel have joined in.

The 2G network only appeared in the mid-90s. At this time, Europe had an absolute advantage. They defeated the United States in the field of communications. Ericsson and Nokia Alcatel occupied most of China's communications market.

So from this point of view, Duan Yun’s future competitors will be these European communication companies. He has contributed money and efforts to support Hou Weigui’s central company and Ren Zhengfei’s Huawei company, in order to let their companies rise rapidly and strive to seize them in the 90s. domestic telecommunications market share.

After wandering around the exhibition hall all morning, the transfer student got a thick stack of product brochures and materials, and then returned to the hotel with Li Yun and others.

"Manager Duan, do you need to translate all of these?" Chen Tiesheng asked the number one scholar with a frown, holding a thick stack of product brochures.

"First find out the product manuals of major manufacturers and translate them. In addition, we will focus on translating some software and chip product brochures. The key is the product introduction. Don't translate other content for the time being." Duan Yun settled down.

"It would be great if I had a computer, handwriting is too slow." Li Yun said with a sigh at this time.

"It doesn't matter, if you work hard these two days, you can translate as much as you can." Duan Yun said with a smile.

In fact, this time Duan Yun participated in the exhibition and visited all the popular booths. Except for the Japanese Nintendo game console, he did not see anything too eye-catching.

As for the MP3 software, it is still in the research and development stage, and the compression ratio of 1:4 is of little significance. If Duan Yun wants to make a mature MP3 product, he still needs to wait for the further upgrade and maturity of this audio coding and compression software.

But through this exhibition, Duan Yun also felt more and more the importance of the software development team.

At present, the person in charge of the software project in Duan Yun Company is Jiang Mingwei, and the others are all computer experts from the Beijing Institute of Autonomous Technology and the Chinese Academy of Sciences. However, this lineup is still relatively thin. After Duan Yun returns to China this time, he still needs to continue recruiting and hiring more people with high salaries. Many software talents.

Another point is that chip design and lithography machine upgrades must also be accelerated. Duan Yun has already paid a deposit to Wang Shi's company before. As for whether he can buy the lithography machine from ASML, it is still unknown...

……

On the fourth day, Duan Yun went to the exhibition site again. After visiting the American exhibition area, he was ready to return home.

It can be said that Duan Yun has gained a lot from participating in the IFA in Germany this time. In addition to buying a large number of foreign language reference books, Duan Yun also got the product brochures of almost all booths. After returning to China this time, he will arrange for the company’s translation All the materials were translated, then copied and bound into a volume, and sent to the technicians of the R&D center, so that they could also understand the current development trend of international electronic technology.

After more than 20 hours of continuous flight, Duan Yun flew from Berlin to BJ, and then returned from BJ to Guangzhou Baiyun Airport.

The books Duan Yun bought in Germany and the list of exhibitions he got will be transported to China by international express DHL. In the mid-80s, a total of 4 foreign transport companies established in China Air Freight Forwarding Company located in BJ. DHL is one of them. The items Duan Yun purchased in Germany will go to China within a week at the earliest.
