"The user experience of the global 5G is insufficient now. It is not completely that 5G is too early and heroes are useless. It should be said that 5G is insufficient. With the development of 5.5G, the future will be an order of magnitude higher than the current 5G." Wu Hequan, academician of the CAE Member, said on the 6th. ▲ Picture source: The 2023 Global Digital Economy Conference was held in Beijing from July 4 to 7. At the 5G Innovation and Development Forum held during the conference, Wu Hequan said that, globally, the 5G network performance is generally insufficient. In May this year, Beijing ranked sixth in the world and eighth in Shanghai. New York in the United States is much worse than Beijing. From the perspective of network performance, China's 5G network performance is still among the top in the world. "At present, however, 5G cannot adapt to the certainty, high reliability and precise positioning of the big uplink, so it is necessary to develop 5.5G to achieve an order of magnitude increase over the current 5G by broadening the spectrum, further expanding the number of antenna oscillators, and giving play to the enabling role of artificial intelligence." Wu Hequan said. Wu Hequan said, "The goal of 5.5G is to be commercially available in 2025. Compared with 5G, it has an order of magnitude increase in several dimensions, not only the improvement of bandwidth, but also the expansion of the Internet of Things, especially the lightweight Internet of Things and the Internet without people, which can well enhance the application of 5G Internet of Things." In addition, one aspect of users' lack of experience of 5G is the comparison with 4G, Wu Hequan said, We have noticed an increase in the utilization rate of 4G. Some people say that operators have narrowed the bandwidth of 4G in order to allow users to access 5G, but in reality, it is not because after 5G was released, 4G was diverted, reducing the pressure on the 4G network, so 4G performance has improved. According to the "Global Digital Economy White Paper" released during the conference, as of May 2023, 256 network operators from 95 countries (regions) provided commercial 5G services, The global 5G population coverage rate is about 30.6%; The global 5G user base has reached 1.15 billion, with China accounting for 58%.
