LoRaWAN network planning, build overcapacity or plan?
summary
Choice reduces to concrete trade offs not buzzwords: either overprovision gateways for low device SF and long battery life or start small and add capacity as metrics demand. Datasheets tout 700,000–1.4M msgs/day claim but reality depends on spreading factor distance and backhaul. Power specifics matter: SF10 ≈8× transmit energy, US payload limits 11 bytes at SF10, gateways draw 2–10 W continuously. Working fixes include edge filtering, solar autonomous gateways, and targeting 7–10 year device lifetimes or adding energy harvesting for hard-to-reach sensors.
