Shanghai Telecom, ZTE and Qualcomm jointly completed 5G-A high and low frequency multi-channel concurrent VR demonstration: the whole process was smooth and without lags

It was reported on July 25 that Shanghai Telecom, ZTE and Qualcomm Technologies cooperated to complete a multi-channel concurrent VR service demonstration under the 5G Advanced (5G-A) high and low frequency NR-DC private network, providing users with on-site experience of VR games. Bringing a 5G-A VR experience with excellent picture quality, smoothness and no lag. In this demonstration, the three parties jointly applied advanced 5G-A technology to actual scenarios, a new attempt to launch large-bandwidth, multi-user VR services in complex network environments, and will be demonstrated to the audience as one of the technical highlights in the ChinaJoy Snapdragon Theme Pavilion. . In this demonstration, the three parties will use the Snapdragon® Connected to the PICO 4 Pro VR all-in-one machine on the XR2 platform. Through the NR-DC private network based on the 800MHz bandwidth of the millimeter wave band and the 100MHz bandwidth of the 3.3GHz low-frequency band, access to the core network agent using the built-in computing engine of the ZTE base station - Node Engine, and directly connect to the VR game server to achieve Support for multiple concurrent VR services. The test results show that when multiple VR services are connected at the same time, the single user rate can reach 80Mbps. During the experience, the VR picture clarity supports @72FPS high picture quality, ensuring that users can obtain a clear, smooth and stutter-free VR experience with excellent picture quality. . It is reported that 5G-A technology can improve the connection capabilities of traditional 5G technology and networks in terms of speed, delay, capacity, etc. Among them, the use of 5G-A's high- and low-frequency NR-DC technology can provide a theoretical downlink peak rate of up to 8.5Gbps in a single base station, and support more than 50 concurrent XR user services, which is the largest capacity of low-frequency independent networking technology. More than 5 times. In addition, high- and low-frequency NR-DC technology has low latency characteristics and can well meet services with stringent latency requirements, such as XR or smart industrial services. The demonstration of multi-channel concurrent VR services under the 5G-A high- and low-frequency NR-DC existing network jointly completed by the three parties will help further promote high-definition live broadcast services, extended reality (XR), ultra-low latency and ultra-high-definition video As well as the development of new applications and scenarios such as industry, the latest 5G-A technology is used to provide users with an immersive new audio-visual experience. Shanghai Telecom, ZTE and Qualcomm Technologies continue to cooperate to promote 5G evolution. This demonstration marks the three parties' new achievements in technological innovation and business verification, providing strong support for global 5G-A business and ecological development. In the future, the three parties will join hands with a wider range of ecological partners to continue to promote cutting-edge technological innovation, significantly improve end-to-end connectivity capabilities, and press the "accelerator button" for the development of 5G-A.
