RANKAN: Off-Grid Mesh Comms & SAR

RANKAN lets you talk, track, and stay safe—anywhere on earth, with or without a signal.

Whether you're on a float trip, hiking, hunting, or managing a high-stakes search and rescue operation, RANKAN keeps your group connected. Using advanced mesh networking, RANKAN turns your phone into a powerful peer-to-peer communication node that doesn’t need a tower to work.

How It Works

RANKAN connects nearby devices using Bluetooth and peer-to-peer Wi-Fi to create a self-healing mesh.

Extend Your Range: Your group helps extend the network—the more people join, the stronger the connection.

Signal Bounce: If any one person in the mesh has a sliver of cell signal, the entire group can relay messages to the outside world.
