metaverse and extended reality (XR) avatar

Rohde & Schwarz and Slalom implement 5G calls via animated avatars

  • The metaverse and extended reality (XR) applications are considered critical to unlocking the full consumer potential of the 5G technology.
  • Rigorous testing is crucial to ensure the performance and market acceptance of these immersive experiences.
  • Rohde & Schwarz and Slalom have collaborated to address this need, developing tools to test XR use cases thoroughly prior to market launch.

 
The 3rd Generation Partnership Project (3GPP) closely examined extended reality (XR) applications with Release 17. This was pivotal in identifying the current limitations and potential enhancements in today’s 5G specifications, paving the way for 5G-Advanced, which will be addressed in Release 18. One of the key areas for 5G-Advanced is the development of animated avatar calls that use augmented reality. This is considered a stepping stone toward a broader integration of the metaverse.

Rohde & Schwarz has partnered with Slalom to create a lab environment. This collaboration has resulted in a test bed for XR-based use cases. At the test bed’s core is the R&S CMX500 5G one-box signaling tester from Rohde & Schwarz. This setup empowers network operators to evaluate XR-based applications and services in a controlled environment, ensuring optimal performance and quality of experience (QoE) for their subscribers even before mainstream deployment.

The animated avatar, developed by Slalom, renders on a cloud computing architecture, which is seamlessly integrated with the R&S CMX500. The R&S CMX500 emulates a 5G network to establish a Voice over New Radio (VoNR) connection to the end-user device. The end-user experience is brought to life using a motorola edge 40 pro 5G smartphone connected to Lenovo ThinkReality A3 Smart Glasses, where the avatar is displayed.

The system also features a loopback of audio samples, laying the groundwork for future audio quality assessments based on the POLQA algorithm. A key aspect of the avatar’s animation is head movement emulation, which is designed to convey attentiveness during calls. The accurate rendering and timely display of such details on the end-user device are among the key performance indicators that are being further investigated by both companies.

This collaboration between Rohde & Schwarz and Slalom opens the way to virtual interactions that are more immersive and personal. For consumers, this innovation promises an enhanced sense of presence and engagement during voice calls.
