Three tools. Zero internet.
Everything runs on the mesh network. Your phone connects to a nearby DanaOne Line device via WiFi and you get instant access to all three.
Your message finds every path
Each DanaOne Line device acts as a relay station. When you send a message, it automatically hops from one device to the next across Danao City's barangays until it reaches everyone on the network.
Even if some devices go offline or get damaged, messages reroute through other paths. The more devices deployed, the stronger the network. This is how CDRRMO maintains communication when cell towers and internet fail.
Long Range radio technology. Reaches up to 10km between devices.
Messages hop device to device. No central server or tower needed.
