Floor plan upload
Upload images or multi-page PDFs and calibrate scale.
LoRaWAN coverage planning
Plan LoRaWAN coverage inside your buildings
Upload floor plans, place gateways, walk and measure real signal, and see coverage as interactive 2D and 3D heatmaps.
No installation — runs in your browser. Invoice billing for CH/EU.
Made for beginners and RF professionals alike
Simple for beginners
A guided workflow: upload a plan, drop a gateway, walk your site. Colours tell you instantly where coverage is good or weak — no RF knowledge needed.
Powerful for professionals
RSSI/SNR/SF per sample, spreading-factor-aware quality index, multi-gateway capture, inner-wall attenuation, live network-server ingest and 3D evaluation.
Two kinds of sites: buildings and outdoor
Model indoor coverage on floor plans, or outdoor coverage on a real map — whatever your project needs.
Building (floor plan)
Upload floor plans of one or more storeys, place gateways and walk each floor. Ideal for offices, warehouses, parking garages, hospitals and industrial sites.
Outdoor (map)
Work on a real map with GPS measurements and terrain elevation — for campuses, districts, agriculture or city-wide coverage.
Everything you need to plan indoor coverage
From the first floor plan to a full 3D coverage model.
Gateway placement
Place gateways on the plan and set their height.
Walk & measure
Record real RSSI/SNR at points as you walk the site.
2D heatmaps
Interpolated coverage field from your real measurements.
3D evaluation
Explore coverage across floors in an interactive 3D view.
Multi-floor
Manage many floors per building in one place.
Campaigns
Group measurements into named test runs.
Device management
Register and manage multiple LoRaWAN devices.
Multi-gateway capture
Record every receiving gateway per point in one measurement.
Signal quality index
A 0–100 score per point, spreading-factor aware.
Live device ingest
Feed real uplinks straight from your network server.
Outdoor & terrain
GPS measurements and terrain-aware outdoor coverage.
Wall attenuation Coming soon
Model inner-wall signal loss (coming soon).
See it in action
Real coverage from real measurements — indoors and outdoors.
What you need to get started
Three things — that’s it. LoRaMapper ties them together.
A LoRaWAN field tester
A handheld LoRaWAN device that sends uplinks as you walk. Its RSSI/SNR at each point is what LoRaMapper maps.
At least one gateway
One or more LoRaWAN gateways — either a portable test gateway you carry, or the fixed gateways you already have on site.
A network server (LNS)
A LoRaWAN Network Server that forwards uplinks to LoRaMapper via webhook — e.g. TTN, ChirpStack, Loriot or Actility. Minimal setup: one HTTP integration.
Mobile or existing gateways — both work
Test with a portable gateway, or measure against the gateways already installed.
Mobile gateway
Carry a portable, battery-powered gateway to the spot you want to cover and measure right there — perfect for planning a new deployment before any hardware is mounted.
Existing (static) gateways
Already have gateways installed? Walk the site with just a field tester and measure real coverage against your live gateways — LoRaMapper records which gateway received each point.
