Hands-on, animated modules that go beyond static diagrams. Click a message in a procedure ladder, drag a slider to recompute throughput, swap a slice — every action is wired to a real 3GPP behavior. Built on top of the CafeTele 5G Network Simulator.
Explore a full 5G SA network in 3D — UE, gNB (RU/DU/CU) and every core NF. Click a node to inspect it, switch the slice, and run a live PDU session UE → UPF → internet.
Animated 5G message ladders. Click any IE to see its definition + 3GPP reference. Scrub, step, replay.
Design an eMBB / URLLC / mMTC slice. Configure S-NSSAI, 5QI, QoS flows. Watch NSSF→AMF set selection animate.
3D ribbon of all NR bands. ARFCN ↔ frequency converter, GSCN/SSB placement, FR1/FR2/FR3 comparator.
3D pipeline UE→RU→DU→CU→UPF→DN. Dial RAN split, fronthaul length, MEC placement → live URLLC budget.
Guided troubleshooter: RACH fail, Registration reject, PDU reject, Handover fail, NAS auth fail. Diagnose & fix.
TS 38.306 peak-rate playground. SCS · BW · MIMO layers · MCS · coding rate → live Mbps. Sliders + math.
UE → RAN → Core → DN in one 3D stage. Toggle integrated vs RU/DU/CU split. Play Registration / PDU Setup / Handover / DL Data — packets fire on every real interface.
The 20 5GC Network Functions — comic panels, flip-cards, and a drag-drop sorting game. TS 23.501 §6.2 made playful.
Drag-and-drop topology builder + every interface (NG-C, F1, E1, Xn, S1) and protocol stack.
How the monolithic LTE eNB became 5G CU-CP / CU-UP / DU / RU. Every split option (1–8) explained.
Each lab is a single self-contained HTML page. No build step, no waiting — open it and the canvas is alive.
Drag a slider, click a message, scrub a timeline. The page reacts the way the 3GPP spec says it should.
Every result, IE, and cause code points back to its 3GPP reference. No mystery values.
Take what you learned back to the main simulator. Build the topology, run the procedures, debug the failures.
