FGRFMesh Offers a Sub-Ghz Alternative for Industrial Communication
Wireless connectivity is one of the most important components in many embedded systems, from industrial automation equipment and distributed sensor networks to autonomous robots and remote telemetry devices. Wi-Fi is the go-to choice for these applications, but it isn't always the best fit. Crowded radio channels, limited range, and dependence on access points can make it an unreliable option. Developers often turn to sub-GHz radios instead, but building a robust mesh network from the ground up — or relying on expensive proprietary modules — introduces its own set of challenges.

FGRFMesh was created to address those problems with an open mesh communication platform designed specifically for sub-GHz embedded development. The project focuses on reliable local wireless links operating in the 868 MHz band, with future plans to support 433 MHz, 915 MHz, and additional radio technologies like LoRa and UWB. Rather than...
