AboutColorado Mesh
Colorado MeshCore is a volunteer-run effort to keep a decentralized LoRa mesh online across Colorado. We deploy infrastructure, document setup paths, and share the same live data operators rely on in the field.
Open LoRa mesh, no internet required
MeshCore is an open-source mesh networking firmware with dedicated infrastructure roles. Unlike simple flood-routing protocols, MeshCore uses repeaters and room servers to intelligently route messages across the network.
Using LoRa (Long Range) radio technology, nodes communicate over many miles — even in challenging terrain like Colorado's mountains. Strategically placed repeaters extend coverage while companion devices connect to your phone over Bluetooth.
Whether you're hiking the backcountry, preparing for emergencies, or curious about decentralized infrastructure, MeshCore provides a resilient communication backbone owned by its community.
Three ideas behind the mesh.
MeshCore separates roles so each node only does what it's good at — companions stay quiet, repeaters route, and the mesh stays resilient.
Direct communication
Nodes talk peer-to-peer over LoRa radio. No internet, cell tower, or carrier required.
Dedicated repeaters
Solar-friendly repeaters on rooftops and ridgelines relay messages efficiently across the metro.
Resilient by design
No single point of failure. The mesh routes around drops automatically as nodes come and go.
A grassroots Front Range network.
Colorado Mesh is a grassroots community of radio enthusiasts, technology advocates, and emergency-preparedness minded operators building a resilient communication network across Colorado — from Fort Collins to Colorado Springs and into the high country.
Build the resilient mesh
Maintain a community-owned LoRa mesh that provides free, open communication infrastructure for everyone on the Front Range.
Open by default
Open source, community-driven, accessible to all. Communication infrastructure should be a public good — never a paywall.
Plains to peaks
Seamless coverage from the Denver metro into the high country, so a hiker on a 14er and a neighbor in a basement can always reach the network.
Four ways into the project.
Operators, builders, teachers, and lurkers welcome. Pick a doorway and meet the community on the other side.
Join the Discord
Coordinate with operators, ask first-radio questions, and stay current on network changes.
Set up a node
Add your own companion or repeater to the mesh — every new node strengthens coverage.
Build the platform
Site, infrastructure, and tooling are all open source. PRs and field reports welcome.
Help newcomers
Share what you have learned, mentor a first-time operator, or write up a setup story.
No corporations, no subscriptions, no data harvesting — just neighbors building the mesh together.
Telemetry, docs, and the wider community.
Live operator tooling lives on this site; deeper telemetry and global community resources live alongside.
CoreScope analyzer
Drill into per-node link quality, neighbors, and routing on the Colorado Mesh analyzer.
Live network map
Real-time map of operator-run nodes across Colorado with live position and link data.
LetsMesh
The worldwide MeshCore community map and analyzer platform.
MeshCore docs
Official MeshCore project documentation, firmware downloads, and reference material.
Operate the network with us.
Whether you're a radio enthusiast, a developer, or someone who simply believes in community-owned infrastructure — there's a place for you in Colorado Mesh.
