Open-source campus coverage tool

Map Your
WiFi & Cellular Coverage

Scan signal strength and download speed at GPS-tagged locations on your phone, push scans to the backend, and view a Delaunay triangulation coverage map on an interactive map.

Everything You Need

From scanning to visualization, NetRange covers the full workflow.

📡

WiFi & Cellular Scanning

Capture WiFi networks and cellular carriers (MTN, Telecel, AirtelTigo) with signal strength and download speed at each GPS-tagged location.

📍

GPS Tagging

Every scan is automatically tagged with precise GPS coordinates for accurate spatial mapping.

🌎

Delaunay Coverage Map

Color-coded Delaunay triangulation shows signal strength across your area. Tap any triangle for dBm and mb/s details.

📱

Auto-Scan & Save

The app detects your active SIM carrier, auto-saves every 2 minutes, and generates the coverage map as you walk or drive.

📊

Speed Measurement

Each scan includes a download speed test. See real mb/s on the map alongside signal strength.

🚀

Crowdsourced

Multiple phones build the same shared coverage map. Friends on different carriers all contribute data.

How It Works

Just open the app and walk. It does everything.

1

Install & Open

Download the Android app and open it. It auto-detects your active SIM carrier (MTN, Telecel, AirtelTigo) or connected WiFi network.

2

Walk & Drive

Every 2 minutes the app auto-saves your signal strength, download speed, and GPS location. No buttons to press.

3

See the Map

The coverage map auto-generates as Delaunay triangles. Open the browser map to switch between carriers and see everyone's data combined.
