The 6G Lab Suite

Four labs, one thesis: make 6G real. A research-grade PHY simulator, a sub-THz/ISAC/NTN engineering simulator, an immersive digital-twin, and an actual running 5G core — sim on the left brain, real silicon on the right.

Link-Level Lab

research-grade PHY · real DSP
depth ◆◆◆◆
most advanced

The full transceiver, Monte-Carlo'd. QAM → OFDM → 3GPP TDL fading → channel estimation → MIMO MMSE / AI-neural detection → max-log LLR → 5G Polar SC decoder.

✓ Real DSP — simulated BER matches closed-form theory (Δlog₁₀ ≈ 0.01). 2×2 / 4×4 MIMO + trained neural receiver.

6G Simulator

PHY engineering suite
depth ◆◆◆
engineering math

Five computational modules: sub-THz link budget with ITU-R P.676 molecular absorption, OFDM numerology, massive-MIMO array-factor beamforming, FFT-based ISAC range-Doppler, and NTN LEO geometry.

✓ Real formulas — array side-lobe −13.2 dB, 60 GHz O₂ wall, LEO Doppler vs elevation.

6G Genesis

living digital twin (3D)
depth ◆◆
immersive

A touchable 3D city where every 6G capability is a layer: ISAC sensing with a live range-Doppler radar, RIS you place on buildings, cell-free MIMO, NTN satellites, an AI-intent engine — all on real IMT-2030 physics.

✓ Real physics engine — Shannon capacity, path loss, beamforming, Doppler per toggle.

Real 5G Core

live Open5GS + UERANSIM
depth ◆◆◆◆
real silicon

Not a simulation at all. A live Open5GS 5G Core (11 real NFs) and a real UERANSIM gNB + UE on the server. Watch a genuine NAS registration & PDU session; attach/detach the real UE and see it re-register live.

✓ The real stack — real NGAP, real registration, real UPF-assigned IP. State shown live in the bar above.
