This is a technical deep-dive into the MeshCore protocol’s architecture. If you’re looking for a buying guide or setup tutorial, start with the MeshCore FAQ or the official quick start.
How MeshCore Scales Where Other LoRa Meshes Hit Walls
The Problem: LoRa Mesh Scaling Is Not Incremental
LoRa radio is a shared, narrow medium. The North American MeshCore preset uses 62.5 kHz of bandwidth, roughly the width of a single FM radio station. Every packet your node sends occupies that medium for everyone else within range. The physics is inescapable: more nodes means more contention, and at some point the network chokes on its own traffic.
