4 - Implementing Adaptive Data Rate
Adaptive Data Rate (ADR) describes the scheme whereby the network server controls the data rate, RF transmit power, and channels an end device uses when sending uplinks, as well as the number of retransmissions made.
The network server uses the Received Signal Strength Indicator (RSSI) of the messages received from the end device to determine how close the end device is to the nearest gateway(s). This allows the network server to select the most appropriate settings for each end device.
The benefits of ADR are that it helps preserve the battery life of an end device and reduces interference, giving all end devices on the network the best chance of communicating successfully.
