Adaptive data-rate

Adaptive data-rate lets LoRa Server control the data-rate and tx-power of the device, so that it uses less airtime and less power to transmit the same amount of data. This is not only beneficial for the energy consumtion of the device, but also optimizes the spectrum.

Important: ADR should only be used for static devices (devices that do not move)!

Activating ADR

The activation of ADR is controlled by the device. Only when the device sends an uplink frame with the ADR flag set to true will LoRa Server adjust the data-rate and tx-power of the device if needed.


To make sure there is enough link margin left after setting the ideal data-rate and tx-power, it is important to configure the installation margin correctly. See also adaptive data-rate configuration.
