Communication DeviceSandesh Communication Device
Reliable, encrypted communication for teams working where there is no mobile network at all.
Stay in touch where the network ends
Remote terrain, disaster zones and border areas often have no mobile coverage, and that is exactly where teams most need to reach each other. Sandesh is a field communication device that passes messages directly between units, so nothing depends on a tower or a data connection.
Each device joins an encrypted mesh with the others, and it pairs with the Sandesh app on your phone for day-to-day messaging.
Built for the places phones can’t reach
The same channel we use for mission relay, packaged as a device your teams can carry.
Works without coverage
No SIM, tower or internet connection is needed for devices to talk to each other.
Mesh networking
Devices link up with each other, so the group covers more ground than any single unit.
Encrypted by default
Messages are protected end to end and stay within your own network of devices.
Works with your phone
Pair it with the Sandesh app to send and read messages from a familiar screen.
