ADR is a setting in LoRaWAN that lets the network automatically tune each device’s radio speed. If a sensor is close to the gateway and has a strong signal, ADR switches it to a faster setting – shorter transmissions that use less battery. If the signal is weak, it slows down to restore range.
The network server – not the device – controls ADR decisions. It monitors signal quality over time and sends adjustment commands in response. One practical note: turn ADR off for moving assets like vehicle trackers. The algorithm assumes a stable signal environment and cannot keep up when a device is crossing cell coverage boundaries.
- Managed by the network server, not the device itself
- Targets the lowest spreading factor that still delivers reliably
- Reduces both battery consumption and channel airtime
- Should be disabled for mobile or high-mobility assets
