Notes from the systems edge.
Field reports on mesh networking, firmware tradeoffs, packet design, and command software for remote endurance events.
Operationally useful engineering work. Less launch theater, more design choices that survive race day.
Designing a LoRa Mesh for Mountain Races
Mountain ultras punish assumptions. The course folds behind granite, weather erases line-of-sight, and aid stations are often the only dependable power source. Our network design starts from those constraints instead of pretending race day looks like a lab bench.
- Relay nodes are staged around terrain transitions, not evenly spaced mileage markers.
- Runner devices transmit on narrow duty cycles so the mesh can scale with field size.
- Backhaul is optional; the local command network must still function when internet links fail.
