LoRa mesh networks for community gardens
A resilient community food network should work before the radios arrive. Build a human protocol, keep the data local, then add the smallest communication layer that solves a real coordination problem.
Open plannerA four-layer path
- 01
Human mesh
Paper boards, scheduled garden walks, phone trees, and known stewards work without power or internet.
- 02
Local digital layer
A browser-local app maps nodes, offers, needs, field records, and compact outbound messages without creating a central public profile.
- 03
Peer radio mesh
Meshtastic or Reticulum can carry short community messages over low-power LoRa and other local links.
- 04
Optional sensor layer
LoRaWAN can connect low-power soil, water, weather, and energy sensors through gateways when telemetry solves a defined problem.
LoRa is not one architecture
- Meshtastic
- An open-source, off-grid, decentralized mesh for affordable low-power devices and short peer messages.
- Reticulum
- An encrypted networking stack that can bridge LoRa, packet radio, Wi-Fi, Ethernet, serial, and other links.
- LoRaWAN
- Usually a star-of-stars system where devices reach gateways that forward data to a network server. It is useful for sensors, but it is not the same as peer mesh.
Design the packet around the decision
Good low-bandwidth messages are short, specific, and actionable: harvest ready, water alert, resource offered, resource needed, tool available, local hazard, or neighbor check-in. Include a known origin and a time window. Do not put sensitive personal, medical, financial, or exact-location data into a neighborhood broadcast.
