The technical purpose of the Adaptive Data Rate algorithm in a LoRaWAN network is to optimize the balance between battery consumption, airtime usage, and connection reliability for end devices. LoRaWAN operates by adjusting two primary parameters: the Spreading Factor, which is the amount of chips per symbol used to encode data, and the transmission power. A higher Spreading Factor increases the range and sensitivity of a signal, making it more robust against interference, but it also increases the t....
