What is Eureka Mesh?
Eureka Mesh is a community-driven Meshcore network providing decentralized communication infrastructure for Eureka, Montana and surrounding areas. Using low-power LoRa radio technology, we're building a resilient network that works even when the internet and cell towers don't.
About Meshcore
Meshcore is a lightweight off-grid communication platform that uses inexpensive LoRa radios to create efficient mesh networks. Client devices communicate directly within radio range, while dedicated repeaters handle multi-hop routing to extend coverage. This architecture reduces network congestion and provides more reliable message delivery than traditional flooding-based mesh networks.

Frequently Asked Questions
What can I do with Meshcore?
Send text messages, share GPS locations, and communicate in emergencies - all without internet or cell service. Perfect for hiking, camping, emergency preparedness, and community coordination.
Why Meshcore instead of Meshtastic?
Meshcore offers more efficient routing (dedicated repeaters vs flooding), clearer message delivery confirmation, lower power consumption for client devices, and better scalability for larger networks. See our full FAQ for detailed comparison.
Is this legal?
Yes! Meshcore uses license-free ISM bands (902-928 MHz in North America). No amateur radio license required.
How far can messages travel?
Between two devices: typically 1-3 km in town, up to 10+ km with line-of-sight. Through repeater network: Messages can hop up to 64 times, enabling coverage across much larger areas.
How much does it cost?
Hardware: $30-80 for client devices. Meshcore core software is free (MIT license). Premium features (GPS tracking, telemetry) are around $10. No subscription fees - the network is free to use.
What's the difference between a client and a repeater?
Client devices are for personal use and communicate directly within radio range. Repeaters are fixed installations that forward messages to extend network coverage. In Meshcore, clients don't relay traffic for others by default, which reduces power consumption and network congestion.
Can I use this in an emergency?
Yes! This network is designed to be resilient during emergencies when traditional infrastructure fails. However, always call 911 for life-threatening emergencies if phone service is available.
