Since 2020, the fifth generation (5G) wireless communication network has been deployed on a large scale worldwide, and more key capabilities are in the process of standardization, such as large-scale connection, high reliability and guaranteed low latency.

The three major application scenarios of 5G include enhanced mobile broadband (eMBB), large-scale machine-based communication (mMTC) and highly reliable low-latency communication (uRLLC). Key performance indicators (KPIs) of 5G include a peak rate of 20 Gbps, a user experience rate of 0.1 Gbps, an end-to-end delay of 1 ms, a mobile speed support of 500 km/h, a connection density of 1 million devices per square kilometer, a traffic density of 10 Mbps/m2, a frequency efficiency of 3 times that of the fourth generation (4G) wireless communication system, and a energy efficiency of 100 times that of 4G. The industry has put forward a variety of key technologies to achieve 5G performance indicators, such as millimeter wave (mmWave), large-scale multiple-input multiple-output (MIMO), ultra-dense network (UDN), etc.

However, 5G will not meet the future network demand after 2030. Researchers began to focus on the development of the sixth generation (6G) wireless communication network.

The research of 6G has been started and is expected to be commercialized in 2030

Although it will take time for 5G to become the mainstream, the research on 6G has been launched and is expected to be commercialized in 2030. This new generation of wireless technology is expected to enable us to interact with the surrounding environment in a new way and create new application models in all walks of life.

The new vision of 6G is to achieve near-instant and ubiquitous connectivity and completely change the way humans interact with the physical world and the digital world. This means that 6G will take new ways to use data, computing and communication technologies to further integrate them into society. This technology can not only support holographic communication, tactile internet, intelligent network operation, network and computing integration, but also create more exciting opportunities. 6G will further expand and strengthen its functions on the basis of 5G, marking that key industries will enter a new era of wireless and accelerate the implementation of digital transformation and business innovation.
