Recently, the International Information Port located in Changping District, Beijing has opened the first 5G-A (5G Advanced) experimental base station in the Beijing area. This base station undertakes the mission of innovating and verifying 5G-A synesthesia integration and passive IoT technology, and is a technology application platform for the integration of 5G-A industry chain innovation chain. What is 5G-A? 5G-A is an enhancement and evolution of 5G, also known as 5.5G. It comprehensively surpasses existing 5G in terms of speed, latency, connection scale, and energy consumption, achieving peak rates of 10 Gigabit downlink and 10 Gigabit uplink, millisecond level latency, and low-cost Internet of Things. "In the view of Xu Xiaodong, the chief expert of China Mobile Group, compared to 5G, 5.5G has outstanding characteristics in three aspects: meticulous resource management, meticulous service, and self breakthrough capabilities. In wireless communication, spectrum resources are very valuable, and "resource budgeting" is reflected in improving the carrier's "turnover rate" and spectrum utilization efficiency through multi carrier cooperation. From the user's perspective, 5.5G network speed will be faster. The "meticulous service" is reflected in the enhancement of user experience consistency in mobile scenarios. For example, users have several base stations to choose from during the mobile process, and 5.5G can predict and quickly select the best signal base station in advance. In addition, 5.5G can also achieve business support under extreme conditions or conditions beyond the reach of conventional communication, such as integrated communication between heaven and earth. The "ability to self breakthrough" is reflected in attempting to break through its performance boundaries through full duplex technology and artificial intelligence air port applications. The experimental base station opened at the Beijing International Information Port is an important attempt in the commercial verification phase of 5.5G. Xu Xiaodong analyzed that from a global perspective, some leading countries are expected to launch the commercial use of 5.5G technology features in the first half of 2025, and it is expected to achieve large-scale commercial use globally by the end of 2025. In the future, as 5.5G gradually integrates into daily life, the general public can also enjoy the novel and convenient experiences it brings. Overall, 5.5G will rely on faster network speeds and lower latency to create more application scenarios. "Xu Xiaodong gave an example, stating that in some usage scenarios, 3D experience can already be achieved through mobile phones, which is due to the explosive growth demand of business capacity. In the future, with the assistance of 5.5G, 3D can bring consumers a stronger sensory experience. In the field of vehicle connectivity, 5.5G can help intelligent driving enter thousands of households through vehicle road collaboration technology, and make people's travel smoother through intelligent control. In the manufacturing field, 5.5G can achieve ubiquitous intelligent connectivity through technologies such as passive IoT, significantly improving the level of digital production and logistics efficiency. For example, when we go to clothing stores in certain shopping malls to check out, we just need to put the clothes in a designated basket, and the machine can automatically recognize the information of the clothes and guide consumers to check out. With the help of 5.5G, as long as consumers walk to a certain place with their clothes, the product information can be automatically displayed, which is the Internet of Things, "Xu Xiaodong said. Nowadays, with the cutting-edge exploration of 5.5G, China's communication industry has become one of the "leaders", with the goal of building a strong network power behind it
