The fifth generation of mobile communication technology, referred to as 5G, is a new generation of broadband mobile communication technology, which has the characteristics of high speed, low delay and Dalian connection, and is the network infrastructure to realize the man-machine Internet of Things. 5.5G is still 5G in essence, but it is faster than 5G and supports more frequency bands. 5.5G can take advantage of carrier aggregation and other technologies to make the network speed go up a storey still higher. For example, the download speed in the original 5G network environment may be 800Mbps, and it can be 1.5Gbps or even 2Gbps in the 5.5G technology. ?

In addition to different speeds, the application scenarios supported by the two networks are also different. In addition to the original mobile bandwidth enhancement of 5G, ultra-reliable low latency and massive machine communication? Triangular ability? In addition, 5.5G has increased the ability of uplink ultra-wideband, broadband real-time interaction and communication perception integration, and expanded the original three standard scenarios of 5G into more powerful scenarios? Hexagon? , which not only enhances the old scene, but also expands the new scene. The three scenarios defined by 5G, eMBB, mMTC and URLLC, have been unable to support more diverse IOT scenarios, such as industrial IOT applications, which require both massive connections and large uplink bandwidth.

5.5G has launched three new application scenarios based on the previous application scenarios, namely, UCBC uplink ultra-wideband accelerated intelligent upgrade of thousands of industries; RTBC broadband real-time interaction, building? Where is it? Immersive experience; HCS integrates perceptual communication to help the development of autonomous driving. 5.5G is an industrial vision and an enhancement and expansion of 5G scenarios. The core content of the 5.5G vision enhances 5G? Third brother? Scene, extension? Sanxin? The scene has changed from a 5G scene triangle to a 5.5G scene hexagon, and from supporting the Internet of Everything to enabling the intelligent network of Everything. In the future, our life will be better. The development of 5G and 5.5G will incubate more application scenarios and accelerate the digital and intelligent transformation.
