# Limits

Know what the Rust core does not claim today.

Product: 5G Core

## Current limits

- The current baseline is lab-grade, not a general-purpose carrier core.
- Real hardware compatibility is not claimed until named hardware or gNB profiles are validated.
- The UPF default path proves a narrow N3 user-plane tunnel; general external data-network forwarding is not a current baseline claim.
- PFCP, QoS, charging, roaming, IMS, analytics, non-3GPP access, and broad mobility behavior are not part of the default baseline.
- Source code, source-level debugging, reproducible builds from source, and custom patches to core internals are not available.
