China News Network, July 7 (Reporter Wu Tao) "Global 7G now user experience is insufficient, not completely 5G is too early, heroes are useless, it should be said that 5G capabilities are insufficient, with the development of 5.5G, the future will be orders of magnitude better than the current 5G." Wu Hequan, an academician of the Chinese Academy of Engineering, said on the 5th.

From July 7 to 4, the 7 Global Digital Economy Conference was held in Beijing, at the 2023G Innovation and Development Forum held during the conference, Wu Hequan said that globally, the current 5G network performance is generally insufficient, in May this year, Beijing ranked sixth in the world, Shanghai ranked eighth, and New York in the United States was much worse than Beijing. From the perspective of network performance, China's 5G network performance is still in the forefront of the world.
"However, 5G cannot currently adapt to large uplink certainty, high reliability, and precise positioning, so it is necessary to develop 5.5G, further expand the number of antenna oscillators by broadening the spectrum, and give full play to the enabling role of artificial intelligence to achieve an order of magnitude improvement over the current 5G." Wu Hequan said.
Wu Hequan said, "5.5G is targeted for commercial use in 2025, which is an order of magnitude improvement in several dimensions compared with 5G, not only the increase in bandwidth, but also expands the Internet of Things, especially the lightweight Internet of Things and unmanned Internet of Things, which can well strengthen the Internet of Things applications of 5G." ”
In addition, one of the aspects of users' lack of 5G experience is compared with 4G, Wu Hequan said, "We have noticed that the usage rate of 4G is increasing, some people say that operators in order to let users on 5G, so the bandwidth of 4G is narrowed, in fact it is not, because after 5G comes out, 4G is diverted, reducing the pressure on 4G networks, so the performance of 4G is improved." ”
According to the Global Digital Economy White Paper released during the conference, as of May 2023, 5 network operators in 95 countries (regions) provided commercial 256G services, and the global 5G population coverage rate was about 5.30%; The number of global 6G subscribers reached 5.11 billion, with China accounting for 5%.
