Wildfire Communications

Wildfires create some of the most challenging communication environments: rapidly changing conditions, disrupted infrastructure, and urgent coordination needs across large areas. LoRa mesh is increasingly used for both community alerting and field operations.

Why mesh works during wildfires

• Cell tower independence: Cell towers near fire zones are often the first infrastructure to fail — whether from power loss, fire damage, or overload as residents attempt to reach family. Mesh operates entirely independently.
• Mobile coverage: Portable nodes in vehicles, on firefighters, or at incident command posts create a mesh network that moves with the response operation.
• Position tracking: GPS-enabled nodes allow incident command to track crew positions in near-real-time without a dedicated tracking system.
• Resilient backbone: Solar-powered repeaters on hilltops continue operating even during extended power outages.

Community alerting use case

A community mesh network with established repeater infrastructure can be activated as a grassroots alerting layer during a wildfire:

• Road conditions and evacuation route updates can be broadcast to all mesh participants
• Nodes in affected neighborhoods can provide "eyes on the ground" status reports
• Air quality readings from BME680-equipped sensor nodes provide hyperlocal data
• Resource availability (shelters open/full, fuel, supplies) can be distributed across the mesh

Field operations use case

For organized response teams (volunteer fire, SAR, CERT):

Minimum viable field kit

• Net control operator with T-Deck Plus (MeshOS) or laptop + Pi room server
• 1–2 hilltop or elevated relay nodes (portable solar)
• Personal nodes for each field team (T-Echo or T1000-E, pocketable)

Operating procedure

1. Deploy hilltop relay node(s) at the highest accessible points overlooking the operational area
2. Net control establishes the operations channel and verifies all teams are visible in contacts
3. Field teams broadcast GPS position updates at 5-minute intervals
4. All significant events are logged as messages (not just voice) for accountability records
5. Net control maintains a position board (GPS positions from all team nodes on map view)
