On the morning of September 8, the 9th China (Mianyang) Science and Technology City International Science and Technology Expo was opened, and Zhang Ping, academician of the Chinese Academy of Engineering, delivered keynote speeches and reports at the opening ceremony and the afternoon forum.

It is understood that Zhang Ping is currently a professor at the School of Information and Communication Engineering of Beijing University of Posts and Telecommunications, the director of the State Key Laboratory of Network and Switching Technology, and an expert of the national 5G and 6G overall expert group.

5G is a bridge connecting information infrastructure and the real economy

Zhang Ping first shared the relationship between 5G and the intelligent connection of everything. He believes that in the past, it was simply to pass information to each other and eliminate uncertainty, but now through artificial intelligence, simple one-way transmission has become a two-way process, which has laid the foundation for the intelligent connection of all things. "Communication is the most basic link, if there is no communication, the data can not be in place, the computing power and algorithm of artificial intelligence are problematic, and the reason why 5G is important is to solve the basic problem of communication." Zhang Ping said.

Zhang Ping further said that communication is related to our overall environment, and once the environment changes, communication also changes. "So we can see from 1G to 5G, and then to 6G later, which is a change in demand, the environment is also changing, what used to be a simple environment, then become a complex environment, and now to the intelligent connection of everything, it will have a great impact on our future lives." Zhang Ping said.

"Overall 4G has changed our lives, 5G has changed our society." Zhang Ping said that he believes that 4G is mainly the role of individual users, and 5G is not only the impact on individual users, but also on the organization, 5G can achieve a large connection, highly reliable communication mode, this way for our intelligent connection of all things provides the foundation. "5G is a bridge connecting information infrastructure and our real economy, for example, 5G can help us better achieve VR and AR." Zhang Ping said.

5G is the highest territory in Sichuan to boost economic development

As an expert in the field of 5G technology, Zhang Ping mentioned in his speech that 5G is the key area of the current global new round of scientific and technological revolution, the highest territory in Sichuan to promote economic development, and the strategic support for Mianyang to build a strong network city, a strong manufacturing city and a smart city.

He said that China is currently in the first echelon of global 5G development, and Mianyang is the second largest city in Sichuan Province, the only science and technology city in China approved by the Party Central Committee and the State Council, and one of the eight service area areas for the national system to promote comprehensive innovation and reform experiments.

Zhang Ping believes that the Ninth Science and Technology Expo coincides with the opening year of the 14th Five-Year Plan, and we should firmly grasp the new development and new stage, practice the new development concept, integrate into the new development pattern, keep an eye on the new round of scientific and technological revolution and industrial change trend, closely follow the national 14th Five-Year Plan, accelerate the construction of the western region, radiate the whole country, face the global innovation ability and scientific research main position, and contribute to supporting China's construction of an innovation highland.

Zhang Ping said that every science and technology expo has a large number of academicians, experts gathered in Mianyang, Sichuan, to discuss the future development of China's science and technology industry, these scientific and technological workers are willing to contribute to the scientific and technological innovation and development of Sichuan and Mianyang, promote scientific and technological self-reliance, and jointly contribute to the high-quality development of Sichuan and Mianyang Science and Technology City.

The new challenges of the industrial Internet faced by 5G

Finally, Zhang Ping shared the problem of industrial upgrading in the 5G era, Zhang Ping believes that the setting of smart factories is that we can achieve flexible manufacturing, which requires the use of wireless 5G technology, but 5G is difficult to solve in the complex environment of the factory, because the communication technology required by different environments is not the same.

Zhang Ping believes that 5G to do the industrial Internet, there is no good model, the biggest problem is that the standard is not the same. "Each factory requires different degrees of reliability, so the previous network facing individuals, its terminal type is consistent, the time requirements are not high, the environment is not sensitive, and the digital space and physical space can be separated, but in the face of the machine network, the type difference is very large, the security requirements are very high, low latency, and the machine is not sensitive to physical space." Zhang Ping said, "In the future, 6G may provide us with a better way to meet the industrial Internet. ”

Finally, Zhang Ping put forward his own suggestions for the future development of Mianyang, he believes that what Mianyang wants to do in the future is talent and the other market. "When the 3G era, the operator once told me that I needed 100,000 professional talents, and now the talent gap is about 5 million, how to bridge this talent gap, this may require all of us to think." Zhang Ping said.
