EXPANDED XR SUPPORT: CAN RAN REALLY HANDLE IMMERSIVE TRAFFIC?

XR (Extended Reality) is often positioned as one of the flagship use cases of 5G Advanced. Immersive experiences. Real-time interaction. Ultra-high data rates.

But behind the hype, there is a fundamental question: Can current RAN architectures really support it at scale? Because XR is not just “more traffic”. It is different traffic.

  • XR requires ultra-low latency with high consistency, not just peak performance.
  • It demands stable throughput, not best-effort delivery.
  • It is highly sensitive to jitter, packet loss, and sudden variations in radio conditions.

In traditional networks, short performance drops are often acceptable. In XR… they are not.

A small interruption can break the entire experience. From an RAN perspective, this introduces new challenges:

  • Scheduling needs to become more deterministic to guarantee consistent user experience.
  • Resource allocation must prioritize stability over raw throughput.
  • Mobility events (handover, beam switching) become critical risk points for session continuity.

And here is where things get more complex. XR traffic is not isolated. It will coexist with:

  • eMBB users consuming high bandwidth
  • IoT devices generating signaling load
  • Background traffic competing for resources

Which means the network must balance very different requirements simultaneously. Now add multi-layer networks, beam-based mobility, and variable radio conditions… And the problem becomes even harder.

Release 18 starts to address some of these challenges with better traffic models and improved support for immersive services. But the real question remains: Are we designing the network for XR… Or expecting XR to adapt to the network?

Because delivering XR is not just about more capacity. It is about predictable performance. And that is something RAN has historically struggled to guarantee.

What’s your view? Is RAN ready for immersive traffic… or are we underestimating the gap?
