"At the end of this year, China may issue a 5G license. Although the base station is now basically commercially available, the terminal needs to wait until the standardization is completed, and it needs to be commercialized, so it will take some time." On the 2nd, 2018 held in Dongguan. At the annual meeting of the Guangdong, Hong Kong, Macao and Dawan District Academicians Summit and the 4th Guangdong Academician Summit, the Chinese Academy of Engineering academician He Hezhen said that from the perspective of 5G construction, we will not be later than developed countries, and once China is commercialized, it will surpass other countries. Because there are many Chinese users.
The summit was hosted by the Guangdong Academician Association and the Dongguan Municipal People's Government. More than 60 academicians and over 100 technicians attended the summit.
Basic technology still has many weak links
He Hezhen revealed that the international standardization process of 5G technology can be completed in September next year. Many countries plan to put into commercial use in the next year, such as Japan will officially use 5G when the 2020 Olympic Games will be held in Tokyo.
It is mentioned that the gap between China's 5G and foreign countries is big or small. Hehe said that we are synchronizing with developed countries in 5G industrialization, and even in some places, it does not mean that it has already surpassed. "Because it is about 5G systems and applications. There are many basic technical requirements for supporting this system, like chips and mobile terminal operating systems. In the 4G era, we can't get rid of dependence on foreign countries. 5G can't be completely improved at once. There are still many weak links in the overall technical support."
Why do many countries actively take 5G? He explained that 5G will be 10 times faster than the existing one, with high reliability and low latency, and can support applications such as high-speed rail and telemedicine at speeds of 500 km/h. “Not only for people's livelihood, but also for economic development. Qualcomm has made predictions with consulting companies. From 2020 to 2035, 5G will increase global GDP by US$3.5 trillion, equivalent to 7% of GDP in that year.â€
"I think 5G is born for the networked car, and it is for the mobile Internet and the industrial Internet, especially the car network." He said, "The car itself is an IoT node and big data source. By 2020, the intelligent network. The company is a broadband mobile intelligent terminal with wheels. It has 5G short-range communication and IoT communication capabilities. It has the ability to connect to low-orbit satellites and Beidou, and can also receive broadcast signals."
By 2020, the global market for automotive electronics systems and car networking will reach $300 billion. Despite the attractive market prospects, He Hezhen expressed his concern. "The automobile electronic system in the Chinese market has been imported almost all over the years. If we don't master the automotive electronic system, there is no way to develop the networked car, and the city's intelligent transportation is not. May be completely realized."
Information space costs are low and pollution is low
The coming of the 5G era will bring smart city construction to a new stage. Guo Renzhong, an academician of the Chinese Academy of Engineering, said in an interview with the Science and Technology Daily reporter that in the information space, many things have the characteristics of lower cost, higher efficiency, least pollution, and minimum emissions. It is a brand-new idea to develop smart cities and solve the problems of geospatial space through the opening and utilization of information space.
"For example, a company that produces small satellites should choose a site. If a complete industrial chain supporting small satellites can be found within 80 kilometers, it is very important for its development. This reasonable industrial layout and scientific preparation require large Data and smart cities are supporting.†Guo Renzhong pointed out that smart cities use modern communication technologies to enhance communication between people and coordinate the relationship between urban agglomerations. It is related to the city's management and management, planning and construction operations.
In addition to shortening the geographical space distance, strengthening the connection and cooperation, the smart city construction can further strengthen the exchange and cooperation between cities through the network space connection. Guo Renzhong used geo-information to study the characteristics of people in several cities in the Pearl River Delta and found an interesting phenomenon: there are many people between Shenzhen and Huizhou on weekends, and there are usually fewer people. The exchanges between Shenzhen and Dongguan are similar in the whole week. “This shows that the industrial integration between Shenzhen and Dongguan is higher and the contacts are closer.â€
In addition, Liu Ke, a foreign academician of the Australian National Academy of Engineering and dean of the Innovation and Entrepreneurship College of Southern University of Science and Technology, pointed out that environmental issues are rooted in energy. To solve environmental problems, we must rely on new technologies to solve and develop new energy sources. He believes that a revolutionary technological breakthrough depends on R&D investment rather than industrial subsidies. The biggest waste is the waste caused by major decision mistakes.
“Be sure to invest in the decision-making arguments, instead of asking a few experts to open a forum or a review meeting, and say that the argument has passed.†Liu Ke believes that the correct decision-making process will have different voices. Comparing the advantages and disadvantages of different programs can avoid major decision mistakes.
Silicon nitride ceramic materials have excellent thermal stability, high oxidation resistance and high dimensional accuracy. Since silicon nitride is a covalent compound with high bond strength and can form an oxide protective film in air, it also has good chemical stability. It is not oxidized below 1200 ° C, and a protective film is formed at 1200 to 1600 ° C to prevent further. It is oxidized and is not wetted or corroded by many kinds of molten metals or alloys such as aluminum, lead, tin, silver, brass, nickel, etc., but can be corroded by molten materials such as magnesium, nichrome, and stainless steel.
