and overall network capacity of the terminal device, the LoRaWAN network server manages the data rate and RF output
of each terminal device separately through the adaptive data rate (ADR) algorithm. Through ADR technology, In the
LORAWAN system, the server automatically updates and sets the node's rate based on the node's signal reception
capability. If the distance is far, the rate is low, and if the distance is close, the rate is high. This greatly improves the
effective bandwidth and load capacity of the network in practical applications.
