Over the past few weeks, I’ve pulled apart four different LPWAN mesh technologies. Now it’s time to bring those findings together and look at which tool fits which job on the property or in the community.

There is no “perfect” protocol. What we have is a set of tools with different trade-offs. I’ve evaluated all four across five parameters to help cut through the marketing noise and get to the technical reality.

The ClusterDuck Protocol (CDP) was where my mesh networking journey truly began. The story behind Project OWL (Organisation, Whereabouts, and Logistics)—students building emergency communication networks after Hurricane Maria—resonated deeply, highlighting a technology designed not for hobbyists or industry, but for saving lives when infrastructure fails. While I found its concepts “much better thought through” from the outset, the project’s slow pace and patchy hardware support meant my personal involvement never truly moved beyond some initial tinkering.

After years of experimenting with various LPWAN mesh networking technologies, I’ve settled on Reticulum as my primary LoRa mesh platform. It emerged as the clear frontrunner not because it’s simpler than the rudimentary Meshtastic (it isn’t), nor because it’s overtly more feature-rich than the structured MeshCore, but because its design philosophy fundamentally aligns with what matters most: privacy, resilience, and true decentralisation. It supports multiple bearer protocols, making it a powerful tool for building a future decentralised network.

While Meshtastic serves as a solid introduction to LPWAN mesh networking, MeshCore represents a move toward more structured networks, particularly when the limits of ad-hoc flooding become a bottleneck. It addresses the “airtime” congestion common in simpler protocols, offering a far more robust path for community-scale infrastructure where a “best effort” approach isn’t enough. MeshCore is built for managed deployments and regional sensor networks where reliability and structured routing are the priority.

For many new to LPWAN mesh networking, MeshTastic often appears as a starting point due to its affordability and active community. It can get you from zero to sending a basic mesh message relatively quickly. For some, it may seem like a convenient entry into mesh networking.

In this post, I’ll dive into what makes MeshTastic tick, where it excels, and where it falls short based on my own experience using it across various scenarios.

Long-range Sub-GHz wireless mesh networks have become essential for modern communication, particularly in remote areas where traditional infrastructure is impractical or impossible. By utilising lower frequencies (typically below 1 GHz), Sub-GHz networks can achieve remarkable range, low power consumption, and the ability to penetrate obstacles such as buildings and dense forests.

These characteristics make Sub-GHz mesh networks ideal for applications in IoT, outdoor communication, emergency response, and industrial networks. But with numerous technologies now available, choosing the right one for your needs can be challenging.
