If you have spent any time in the off-grid radio scene over the last few years, you know the frequency divisions. You either ran on the sub-GHz bands (915 MHz in Australia and the Americas, 868 MHz in Europe) for long-range, bush-penetrating reliability, or you accepted the high-congestion limits of local Wi-Fi. It was a trade-off we took for granted. If you wanted to send a message across 10 km of dense stringybark, you needed the long waves. If you wanted global hardware standardisation, you looked elsewhere.

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.

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.
