IP400 Project
The IP400 project is a new development to bring a high speed mesh networking system to the 400MHz band.
The initial phase of this project was to investigate the applicability of new off the shelf components that are designed for the IEEE 802.15.4 protocol in the 400MHz band. The manufacturer provided an evaluation board that was used for some early development. Beyond that, the project has added three development efforts:
Mini Node. A simple low power node realized on a Pi Zero HAT, that can join a mesh network and send at speeds up to 100Kb/s.
Power Node. The next generation of node that features a power amplifier and coaxial collinear antenna for outdoor use, powered by POE. In development, should be available in the Spring of 2026.
Super Node. A node that enhances aging repeater systems that is Allstar compatible in the analog world, and adds three new data modes; a compatible mode with the existing nodes, an enhanced data mode for mobile or fixed station use that is compatible with current applications, and a high speed OFDM mode for point to point and point to multipoint linking. In development now, available late 2026.
A presentation on the project was made at the Zero Retries Digital Conference in September of 2025, click the button below to view it.
