Real 5G Core + RAN — Live Stack

Not a simulation. A live Open5GS 5G Core (11 real network functions) + a real UERANSIM gNB & UE running on the server. Watch an actual NAS registration & PDU session, see the UPF-assigned IP, read live AMF signalling, and attach/detach the real UE — every value read live from the running stack.

6G Lab — Complete Workbench (all-in-one)

Every 6G lab in one app, as tabs: a live 5G Core (real Open5GS + UERANSIM, attach/detach, SBA topology, call-flow), the research-grade Link-Level PHY simulator (MIMO + neural RX), the 6G PHY Simulator (sub-THz/ISAC/NTN/beamforming), the immersive 3D digital-twin, the IMT-2030 usage scenarios, and the AI-Native 6G Core architecture (3GPP TR 23.801 + RAN, spec-cited). One place for everything 6G.
