People and portable units
Staff or field devices can exchange short messages and status with the network.
Program / MeshCore / Explainer
Small packets.
Long reach.
MeshCoreAn open-source, off-grid mesh communications system that uses LoRa-capable nodes to relay messages across a network.Crux usage: Crux uses MeshCore as a resilient public and fallback communications layer for field nodes, mobile diagnostics, and selected sensor or Daymark events. Private Crux operational data remains separately governed.Open full definition gives selected Crux nodes a low-power route for short messages and telemetry when ordinary infrastructure is unavailable, unnecessary or intentionally quiet.
01 / Plain language
A low-power radio path when the internet is absent or inappropriate.
What MeshCore is
MeshCore is an open-source, off-grid communications system built around LoRa radio. Companion devices, repeaters and applications can exchange short messages across a decentralised network without relying on cellular or Wi-Fi infrastructure.
What it is not
It is not a broadband network, a replacement for emergency services, or a route for cameras and large datasets. Its strength is small, deliberate packets: messages, position, acknowledgements and selected telemetry.
02 / Crux use
Quiet communications inside a larger operating system.
Coverage infrastructure
Fixed relays extend the route between nodes without becoming the public source of truth.
Events become accountable
AtlasCrux’s governed operational intelligence system for interpreting system state, coordinating workflows, and presenting actions or decisions.Crux usage: Atlas connects engineering records, sensor data, communications, automation, evidence, and publishing. Material changes remain subject to validation rules and human approval.Open full definition can translate selected radio events into status cards, logs and escalation workflows.
Useful when primary links fail
MeshCore supplements Ethernet, Wi-Fi and SMS rather than pretending one medium solves every problem.
