Off-grid convoy comms

Who's still behind you?

Ten minutes past the turnoff the phone gives up — no signal, no data, no way to know whether the tail-end truck took the wrong track. Keep scrolling.

Getting the group together

Add your mates with a four-digit code.

One truck starts the convoy and reads out a short code; everyone else taps it in once. From there the group is closed — each convoy carries its own key, so only the trucks you let in can read what's on the air.

• Four-digit code
• Its own key
• No accounts

On the move

The whole group on one map.

Everyone who joined shows up as you drive — who's leading, who's dropped back. Send the group a message without picking anything up, or drop a waypoint the others can steer to.

• Live positions
• Messages
• Waypoints

Self-healing mesh

The trucks are the network.

Lead can't reach the tail-end truck, so the one in the middle passes the message on — because the tail-end says it is still missing it. Every rig relays, the mesh closes over any gap on its own, and it runs on the 915 MHz band.

• About 5 km between rigs
• Every rig relays
• 915 MHz band

Fitting it

On the dash, wired to the truck, done.

Twelve or twenty-four volts straight off the vehicle, or a USB-C power bank when you're out of it. The antenna is in the box; the roof kit is there for the days you want more reach.

• 12/24 V
• USB-C
• Antenna included

Every edge, explained

What plugs into it.

Nothing proprietary and nothing you can't buy at a servo. Keep scrolling for the rest of the hardware.

On the outside

What sticks out of it.

Two standard SMA connectors, so you can run the antenna in the box or put a proper one on the roof.
