Yesterday, at the World Telecommunication and Information Society Day Conference held in Ningbo, China Mobile, China Telecom, China Unicom, and China Radio and Television jointly launched the commercial promotion of 5G cross-network roaming.
China launched the commercial promotion of 5G cross-network roaming
5G cross-network roaming means that users can access the 5G network of other operators and continue to use 5G services when the operator to which the user belongs has no 5G network coverage. In areas where 5G cross-network roaming is enabled, users can use terminals that support 5G cross-network roaming, and can directly use the service for free without changing cards and numbers.
Wang Zhiqin, Vice President of China Academy of Information and Communications Technology: It reduces duplicate investment, improves the efficiency of the entire 5G network construction, and more importantly, in many remote areas, it can quickly build and achieve 5G network coverage, so that more people in border areas can enjoy 5G services faster and reduce the digital divide.
On May 17, 2023, four basic telecom companies launched the world's first 5G cross-network roaming trial commercial use in Xinjiang, and in the past year, 5G cross-network roaming services have been launched in various states and cities in Xinjiang, effectively verifying the feasibility of 5G cross-network roaming on the existing network.
Ministry of Industry and Information Technology:
Clearly strengthen the key technological breakthroughs of 5G-A
The relevant person in charge of the Ministry of Industry and Information Technology said yesterday that it is necessary to strengthen the breakthrough of 5G-A key technologies. Industry insiders pointed out that 5G has been commercialized for 5 years, and as a transition technology from 5G to 6G development, this year will become the first year of 5G-A development.
Sun Ji, Deputy Director-General of the Information and Communication Development Department of the Ministry of Industry and Information Technology: Deploy and carry out 5G-A network construction on demand, promote 5G-A network coverage in key cities and hotspots based on application scenarios, closely follow the differentiated and personalized needs of vertical industries, and stimulate the creation of 5G-A growth value in terms of higher speed, larger connection, and lower latency.
5G-A is an evolution technology from 5G to 6G, which has better network performance than 5G, and the theoretical peak rate can reach 10G. At present, China Mobile has taken the lead in promoting the commercial deployment of 5G-A in 100 cities, and will expand to 300 cities within the year. China Telecom has used 5G-A technology to build low-altitude private networks in Nanjing, Xi'an, Shenzhen, Guangzhou and other cities. Empowering the low-altitude economic industry, China Unicom has built a product system covering the whole industrial chain of 5G-A synaesthesia, passive IoT and other technologies, and actively carried out pilot verification.
Wen Ku, Chairman of China Communications Standards Association: Operating enterprises are gradually deploying, and in many key areas and key areas, our network has been upgraded and transformed, and lightweight terminals are also constantly improving. Therefore, these aspects have laid a good condition for the large-scale promotion and application of (5G-A) market.
Reporter observed:
5G+AI helps scientific and technological innovation
The theme of this year's World Telecommunication and Information Society Day conference is "Digital Innovation Empowering New Industrialization". Digital innovation technology not only promotes industrial transformation and upgrading, but also boosts scientific and technological innovation.
The Sichuan solar cell manufacturer has built the world's first new smart factory in the photovoltaic industry through 5G + AI. The 5G indoor intelligent navigation transport vehicle in the workshop and the automatic robotic arm on the production line have replaced the traditional manual handling and grabbing; The intelligent sorter that recognizes images through photographic analysis also realizes the interconnection and intelligence of material supply management, production monitoring and equipment management. Warehousing and logistics and intelligent manufacturing have all achieved digitalization and intelligence, which has greatly improved production efficiency.
Luo Ning, General Manager of Sichuan Telecom's Wireless Network Center: Compared with the traditional solar cell production line, the production efficiency of the 5G+AI smart factory has been increased by 1.6 times, the cost has been reduced by 25%, and the energy consumption has been reduced by about 30%.
In Xi'an, Shaanxi Province, digital innovation is contributing to basic scientific research. The National Timing Center of the Chinese Academy of Sciences is jointly building the world's largest, most complete and most advanced ground-based timing system with Shaanxi Mobile.
Zhang Shougang, Director of the National Time Service Center of the Chinese Academy of Sciences: The project uses China Mobile's abundant optical cable and computer room resources to build an efficient, flexible and reliable "optical base", with 10 picosecond (100 billionths of a second) level of stability transmission conditions, which can make the "Beijing time" timing accuracy reach 100 billionths of a second, serving the operation and development of the national economy and national security.
