Meshcore – LoRa

The Kings Point Amateur Radio Club has deployed the Meshcore LoRa Mesh Network, a modern digital communications system designed to demonstrate resilient, infrastructure-independent networking. MeshCore operates using LoRa (Long Range) radio technology, a low-power spread-spectrum radio protocol optimized for long-distance data transmission with minimal bandwidth. In this architecture, each node functions as both a user device and a relay, automatically forwarding packets between neighboring nodes to form a self-healing mesh topology. Messages are dynamically routed across the network, allowing communications to continue even if individual nodes go offline.

Our club network operates on 910.525 MHz within the unlicensed ISM band, enabling low-power devices to participate without requiring an amateur radio license while still supporting meaningful experimentation with digital radio networking. Text messages and telemetry can travel several miles by hopping between nodes, with each additional device expanding the overall network coverage.

By deploying this system, the Kings Point Amateur Radio Club is exploring practical mesh networking concepts while building a resilient local communications platform for experimentation, community coordination, and emergency preparedness.

The system automatically generates keys for hashtag topics, and these keys are provided to aid users whose devices cannot type the “#” symbol or perform the key calculation themselves.
