Group Messaging Via Mesh
Coordinate group communication offline using MeshCore. Stay connected between family members, neighbors, or outdoor groups in any situation.
Why Group Messaging Matters Off-Grid
During outdoor activities or off-grid situations, broadcast communication becomes essential. Individual messaging takes time—you need single messages reaching entire families, trail groups, or volunteer teams instantly. With MeshCore group messaging, exactly this becomes possible, completely independent of internet availability.
Channels work similarly to WhatsApp groups, but transmit via radio frequencies. Every subscriber to a channel receives your messages immediately. Perfect for organizing coordination, sharing information, or managing group activities.
Types Of Channels
📻 Open Channels
Anyone within reception range can listen and contribute. Great for general announcements, weather updates, or community information. Note: messages are not encrypted.
🔒 Secured Channels
Only holders of the correct encryption key may participate. Ideal for family communications or small groups. Encryption ensures privacy.
🏘️ Neighborhood Channels
Dedicated frequencies for your street or subdivision. Coordinate with immediate neighbors, share local information, arrange mutual assistance. Expands organically with network growth.
🚨 Priority Channels
Reserved for genuine urgencies. Maximum priority, minimal chatter—critical messages only. Keep clear for real needs.
Using Group Messaging
1. Subscribe To A Channel

4. Monitor Multiple Channels
