Shanghai Telecom, ZTE and Qualcomm jointly completed a multi-channel concurrent VR service demonstration based on 5G-A high and low frequency NR-DC private network

Recently, Shanghai Telecom, ZTE and Qualcomm Technologies collaborated to complete a multi-channel concurrent VR service demonstration under the 5G Advanced (5G-A) high- and low-frequency NR-DC private network, bringing picture quality to users who experience VR games on-site. Excellent, smooth and lag-free 5G-A VR experience.

This demonstration is a new attempt by the three parties to apply advanced 5G-A technology to actual scenarios and launch large-bandwidth, multi-user VR services in complex network environments. It will be one of the technical highlights in the ChinaJoy Snapdragon Theme Pavilion. One is shown to the audience.

In this demonstration, the three parties will use the smartphone form terminals equipped with the Snapdragon The PICO 4 Pro VR all-in-one machine on the Long XR2 platform is connected through an 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, and accesses the Node Engine, the built-in computing engine of the ZTE base station. The core network agent is directly connected to the VR game server to support multi-channel 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. .

5G-A technology can improve the connection capabilities of traditional 5G technology and networks in terms of speed, latency, 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 XR user concurrent 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.
