Metaverse or Realverse? Quality of Experience in Extended Reality Telecommunications

Extended Reality (XR) technologies are being proposed as the next technological step to improve human communications. XR can potentially offer users in different parts of the world to communicate with the same effectiveness as if they had physically traveled to the same location for a face-to-face meeting. However, this “teleportation” experience requires the real-time transmission of a huge amount of data with minimum latency. In this talk we will explore the basic building blocks of XR communication systems and the resource-versus-quality trade-offs that need to be addressed to provide those services with enough Quality of Experience.
