No signal?
No problem.
Cell towers choke when tens of thousands of people show up. Pocket-sized LoRa mesh radios keep you texting, sharing location, and finding your crew, with no towers and no data plan.

Share live location with your group and meet at the stage, not "somewhere near the food trucks."
Works without bars
Messages hop device to device over long-range radio. No SIM, no Wi-Fi, no subscription.
Battery friendly
A small node runs for days. Your phone only needs Bluetooth to talk to it.
What is a mesh network?
Mesh radios use LoRa, a low-power, long-range radio technology that runs on unlicensed spectrum (915 MHz in the US, 868 MHz in Europe). Each small device pairs with your phone over Bluetooth. You type a message, your device broadcasts it, and nearby devices can relay it onward so it reaches people beyond direct range. It's built for short text and location, not video or calls.
Two networks, one idea
Meshtastic
The big, friendly, widely adopted option. Huge community, tons of supported hardware, polished apps.
MeshCore
Newer, with structured routing through repeaters designed to scale to large networks.
| Meshtastic | MeshCore | |
|---|---|---|
| Relaying | Nodes rebroadcast ("flooding") with hop limits | Dedicated repeaters route; phones/companions don't relay |
| Best for | Small to mid groups, location sharing, easy start | Larger, planned networks with fixed repeaters |
| Community | Very large, lots of docs | Growing fast |
| Join a channel | Scan QR / open link | Scan QR / add channel |
Not sure which? Grab a device that supports both and flash whichever your crew picks. Many popular boards run either firmware.
Why festivals?
- Congested cell networks make texts and maps unreliable exactly when you need them.
- Lose your camp? Drop a location pin and navigate back at 3 a.m.
- Split-up groups can set meetup points and check in without burning phone battery on data.
- Community channels let volunteers and attendees share info like water spots or lost items.
