Landlink

Developer Tools

Free · Designed for iPad. Not verified for macOS.

Build your own off-grid mesh. Pair a radio module, deploy drone relays, and send text up to 50km from anywhere. No cell tower required. Landlink turns your iPhone into the control center for a private long-range mesh network. Pair a Landlink Module over Bluetooth and start sending text across kilometers of open terrain. Add a Landlink drone and stretch coverage up to 50km from a single ground node, without relying on cell towers, Wi-Fi, or any existing infrastructure. Whether you are coordinating a remote worksite, exploring backcountry trails, or building resilient comms for emergencies, Landlink keeps your team connected where conventional networks fall short. KEY FEATURES Long-range text messaging Send and receive messages across a self-healing mesh built from low-power radio modules. Every node ships pre-configured to relay text payloads out of the box. Drone-powered coverage Add a Landlink drone to lift a node into the air. A single airborne relay extends the mesh up to 50km from a ground station. Chain multiple drones to push coverage across ridges, forests, and coastlines. Two-way control The same mesh that carries your messages also steers the drones above it. Reposition any node, set a new patrol path, or recall the fleet straight from your iPhone. No separate ground controller required. Local Bluetooth pairing Connect to your Landlink Module over Bluetooth Low Energy. Pairing happens entirely on-device, so once your mesh is up it runs without internet or cellular service. Multi-channel messaging Organize conversations into named channels. Switch quickly between operations, scouting, and logistics without losing message history. Device dashboard Monitor signal strength, battery level, and link quality of every node in your mesh from a single screen. Spot weak hops before they break the network. Meshtastic compatibility Landlink speaks the Meshtastic protocol, so existing Meshtastic nodes can join the same mesh as your Landlink hardware. Built for the field Light, dark, and system themes designed for readability in direct sunlight and low-light field conditions. HOW IT WORKS 1. Open Landlink and pair with your Landlink Module over Bluetooth. 2. Power on additional modules to form a ground mesh. 3. Launch a Landlink drone to add a flying relay and stretch the mesh up to 50km. 4. Start a channel, send a message, and watch it hop across the network. WHO IT IS FOR Backcountry hikers, climbers, and paddlers who need to stay in touch beyond cellular coverage. Search and rescue teams coordinating across rough terrain. Film and survey crews working on remote sets and worksites. Emergency preparedness planners building offline-ready comms. Makers and radio enthusiasts exploring long-range mesh networking. HARDWARE Landlink Module I is enough to start a small mesh on its own. Add a Landlink I drone whenever you need to push coverage further. Optional camera, microphone, and speaker modules can be added for richer media. PRIVACY Landlink does not require an account to send messages over your local mesh. Pairing and message routing happen locally between your iPhone and your hardware. SUPPORT Questions or feedback? Open the in-app FAQ or email jun@cartesiancs.com.
