Join our open regional channels in the MeshCore mobile application to converse with the community or test your transceiver node.

#alamancelive Primary Public

The primary general chat room for Alamance County. Use this channel for regional off-grid chat, network status updates, emergency communications, and community discussion across Burlington, Graham, Mebane, and surrounding areas.

#test Signal Testing

Dedicated channel for signal checks, RSSI/SNR tests, automated telemetry pings, and verifying range with local stationary repeaters. Keeps test chatter clean from the main public channel.

PROTOCOL ARCHITECTURE

What is MeshCore?

MeshCore is a lightweight, open-source C++ library designed for multi-hop packet routing over LoRa radios. It keeps communities connected without cellular towers or internet infrastructure.

⚡

Intelligent Routing

Selective multi-hop packet forwarding prevents unnecessary channel congestion and optimizes airtime usage compared to standard flood routing.

🔒

End-to-End Security

Cryptographic identity verification paired with AES encryption ensures private text and sensor telemetry remain secure across the public radio band.

🔋

Ultra-Low Power

Designed for multi-day battery and solar operation. End-user companion nodes refrain from repeating overall network traffic.

🌐

Self-Healing Mesh

If an intermediate repeater goes offline, surrounding nodes automatically discover alternate routes to maintain grid resilience.

Mesh Infrastructure Overview

MeshCore relies on dedicated stationary repeaters to handle channel routing while mobile companions remain low-power clients:

Repeater
Grid Backbone Node: Fixed infrastructure mounted on rooftops, towers, or ridges operating 24/7. Listens, routes, and retransmits packets across Alamance County.
BLE Companion
End-User Client Node: Connects via Bluetooth or USB to smartphones or laptops for messaging, mapping, and field telemetry without forwarding traffic.
Room Server
Bulletin Board System (BBS): Operates as an off-grid store-and-forward server, allowing users to leave and read public group posts.
