Gateways

Coverage heatmap: green = strong signal, yellow = marginal, red = just receivable. Transparent = below threshold.

The gateway layer lets you place LoRaWAN gateways on a floor plan and visualises which cells each gateway can receive from, based on a 868 MHz radio propagation model.

Coverage formula

margin = txPower − FSPL(d) − wallAtten − noiseAtGateway − snrThreshold

For each grid cell, the application computes the link-budget margin. A cell is covered when margin ≥ 0 — the received signal exceeds the noise floor by at least the SNR threshold.

Placing gateways

Click Gateways → Place gateway to enter gateway edit mode.
Click any empty cell to place a gateway.
Click an existing gateway to select it. Click Delete to remove it or Disable to exclude it from simulation.
Click the gateway icon again or press Escape to exit edit mode.

3D multi-floor coverage

The 3D view stacks all floor plans and shows inter-floor coverage via ghost gateways.

Gateways on adjacent floors contribute to coverage via the ghost gateway model. Each adjacent-floor gateway appears as a phantom marker with reduced TX power (original power minus slab attenuation). Coverage across floors is computed automatically when floor numbers are assigned.
