When the cell towers disappear, Overlander's peer-to-peer mesh keeps your convoy talking — no infrastructure required.
A mesh network is a group of devices that talk directly to each other — no central server, no cell tower, no internet connection needed. Each phone in your convoy becomes both a receiver and a relay, extending the range of the whole group.
Overlander's mesh layer is built into the app. The moment you lose mobile signal, it automatically activates. Your crew keeps seeing each other's positions. Messages keep getting through. The adventure keeps going.
Overlander mesh activates automatically when cell coverage drops.
Everyone in your convoy downloads the Overlander app. No extra hardware, no special setup — the mesh is built in.
Create a trip and invite your crew. Once everyone joins, Overlander knows who's in your convoy and keeps them in sync.
Drive into the wilderness. When signal drops, Overlander's mesh activates automatically. Positions and messages hop between devices to reach the whole group.
The mesh operates over Bluetooth and Wi-Fi Direct, giving each node an effective range of several hundred metres in open terrain. Each device relays signals further, so a convoy spread over a kilometre can still communicate end-to-end.
All mesh messages and location data are end-to-end encrypted within your trip group. Nobody outside your convoy can read your comms — not even us.
Mesh mode is designed to be lightweight. We only broadcast what's necessary — your position, your messages — and we do it efficiently so it won't flatten your phone before lunch.
Regain cell signal mid-trip? Overlander seamlessly switches back to the cloud, syncs any missed updates, and keeps your trip map accurate — without you lifting a finger.
Download Overlander free and never lose your convoy again — even at the edge of the map.
