On April 6th, the reporter learned that China Telecom and China Unicom have recently successfully completed the world's first full frequency, full standard, and full scenario 5G lightweight commercial verification in five provinces (cities) including Zhejiang, Guizhou, Guangdong, Henan, and Shanghai, and officially launched the commercial process on a scale of 100 cities. Under the guidance of the Ministry of Industry and Information Technology's Notice on Promoting the Evolution and Application Innovation Development of 5G Lightweight (RedCap) Technology, the innovation verification and commercialization of 5G lightweight technology for 5G-A evolution are accelerating. 5G lightweight technology is an important direction for the development of 5G networks. By reducing the size, weight, and power consumption of 5G devices, the portability and flexibility of 5G devices can be improved, providing users with faster and more reliable network connections. Lightweight 5G networks can also reduce network construction and maintenance costs, improve network efficiency and sustainability. 5G lightweight has great application potential in the field of Internet of Things, which can provide strong network support for the innovative development of smart cities, industrial Internet, intelligent transportation and other fields. It is understood that this commercial verification covers multiple frequency bands such as 3.5GHz, 2.1GHz, 900MHz, and 800MHz, and can support more than 20 high-definition video concurrent requirements in IoT applications; The seamless switching success rate between 4G and 5G networks has reached 100%, providing a highly reliable network connection service guarantee for high mobility applications such as the Internet of Vehicles. At the same time, this verification covers all indoor and outdoor 5G-A IoT commercial scenarios, including densely populated urban areas, general urban areas, townships, rural areas, and mountainous areas, achieving network improvement and coverage in various complex scenarios, and ensuring stable connectivity anytime and anywhere. The success of this commercial verification proves that the current network environment has the comprehensive commercial capability of 5G lightweight. 5G lightweight can be widely applied in industries, energy, logistics, smart cities, vehicle networking, and wearable devices. At present, Shenzhen, Xi'an and other places have taken the lead in opening up comprehensive 5G lightweight services. (Lai Xin She)
