  The advent of the Metaverse concept has further expedited the evolution of
haptic, tactile internet, and multimedia applications with their VR/AR/XR
services, and therefore, fully-immersive sensing is most likely to define the
next generation of wireless networks as a key to realize the speculative vision
of the Metaverse. In this magazine, we articulate different types of media that
we envision will be communicated between the cyber and physical twins in the
Metaverse. In particular, we explore the advantages grasped by exploiting each
kind, and we point out critical challenges pertinent to 3D data processing,
coding, transporting, and rendering. We further shed light on the role of
future wireless networks in delivering the anticipated quality of immersion
through the reliable streaming of multimedia signals between the digital twin
and its physical counterpart. Specifically, we explore emergent communication
paradigms, including semantic, holographic, and goal-oriented communication,
which we expect to realize energy and spectrally efficient Metaverse while
ensuring ultra-low latency.
