6.4 Adaptive data rate (ADR)
ADR is part of the LoRaWAN standard where the network server determines the optimal rate of
communication for the module based on current signal conditions. In best case, the module will use its
highest data rate (DR5) in order to be as energy-efficient as possible. When signal conditions are poor,
the network server will incrementally lower the data rate until it is able to receive the message. When the
data rate is low, the energy consumption per telegram will increase.
6.5 Transmit interval
6.5.1 EcoMode
When EcoMode is active, a battery-lifetime of at least 11+1 years is guaranteed for the module. The
module is able to achieve this by adapting its transmit interval to current signal conditions on the
LoRaWAN network. In other words, when signal conditions are poor (and data rate is low), the module
will send data less frequently in order to conserve battery-life. When signal conditions are decent, the
module will be able to send data more frequently.
