On February 17, Zhang Feng, the chief engineer of the Ministry of Industry and Information Technology, stated at the news conference on the development of the industrial communication industry in 2016 that China had fully launched the 5G technology R&D experiment at the beginning of last year and it has now entered the second stage, jointly promoting the 5G industry at home and abroad. Mature the chain.
Zhang Feng emphasized that China and the international have started 5G research and development simultaneously. In recent years and during the “Thirteenth Five-Year Plan†period, a major new generation of broadband wireless mobile communications networks has focused on supporting the research and development of 5G. “At present, China’s vision, needs, and concepts in 5G We have made a series of positive developments in wireless technology and network architecture, and our major viewpoints have been widely recognized by the global industry."
Zhang Feng also disclosed that China has also accelerated the planning of 5G frequency. The Ministry of Industry and Information Technology has approved the development of 5G system technology in the 3.4-3.6GHz band last year. Currently, research and coordination of other relevant frequency bands are being carried out.
China started the 5G technology R&D experiment early last year. Zhang Feng also stated that during the 5G R&D process, China must strengthen cooperation with the world and jointly promote the maturity of the 5G industry chain at home and abroad.
"Compared with 5G and 4G, 5G has a higher speed and wider bandwidth to meet consumer demand for higher network experiences such as virtual reality and ultra-high definition video. On the other hand, it also has higher performance. Reliability and lower time delay can better meet the application requirements of autopilot, smart manufacturing and other industries, realize the interconnection of all things, and can more effectively support the economic and social innovation and development."
In terms of mobile communication technology standards, China has achieved "2G follow", "3G breakthrough", and "4G synchronization", and it has achieved simultaneous global leapfrogging. China's promotion of TD-LTE-Advanced has become one of the 4G standards. Nowadays, 5G R&D has been carried out synchronously with the world.
At the end of last year, the "13th Five-Year Plan" for information and communication industry was formally released. The plan emphasizes the promotion of the construction of a strong network of countries as the center, and promotes the integration and development of information and communication industries and various sectors of the economy and society as the main line, and proposes 19 quantitative indicators. .
Zhang Feng said that compared with the “Twelfth Five-Year Planâ€, major indicators such as Internet penetration rate, M2M, IPv6, and user complaints were increased, and it was also clear that by 2020, new high-speed, mobile, security, and ubiquitous technologies should basically be built. The first-generation information infrastructure has initially formed a modern, internet-based, intelligent, service-based, and collaborative Internet industry system. Its capacity for independent innovation has been significantly enhanced, emerging industries and integrated applications have flourished, and the ability of the information and communication industry to support economic and social development has been fully enhanced. .
According to Zhang Feng, the plan also laid out the deployment for the development of the industry in the next five years. First, it is necessary to strengthen planning guidance, do a good job of layout, make overall plans for the development of network power strategy and follow-up implementation, and clarify the implementation framework and implementation path of the industrial Internet. , Actively promote the development of industrial Internet, pay close attention to 5G research and development and industry promotion, to lay the foundation for 5G start commercial services.
