Text description of the map

The map holds 0 gateway(s) and 0 node(s).

Step 1

Place your nodes

One gateway, three nodes, one coverage ring per spreading factor. Drag a node: outside the ring, the gateway hears nothing.

Step 2

Type real AT commands

The terminal talks to the node’s daemon. AT+JOIN goes to ChirpStack; +EVT:JOINED comes back once the network accepts.

AT Terminal (LoRaWAN) 40

Step 3

Read what is on the air

Every frame lands in the inspector: DevAddr, port, payload, MIC, RSSI, SNR. These are the real values of the recorded session.

Aucune trame capturée. / No frames captured yet.

Step 4

The teacher sees everything

Who joined, who is sending, how many frames. Kill the gateway: the rings vanish and nothing gets through.

Five protocols, one map

Each protocol has its own range, computed by the radio engine. Pick one: the map changes scale.

Who it is for

  • BTS and BUT: structured labs, no hardware budget, no dedicated room.
  • Bachelor’s and master’s: ADR, multi-hop mesh, IPv6, simulated failures.
  • Teachers: build the lab, disturb the radio live, follow the cohort on one screen.

  • Buying for an institution?

Who is behind VirtIoT Lab

VirtIoT Lab is built and hosted in France by Joffrey Herard, an IoT networking trainer, in Reims. The platform grew out of a teaching-room problem: running LoRaWAN, Zigbee, Thread and NB-IoT labs without a hardware budget and without radio interference.
