- | For this, you will start by identifying a set of geographical locations or Test Points (TP). These TPs should be astutely chosen to explore the limits of LoRa coverage. Then you should implement a function on the server that measures the ratio of successfully delivered packets or PDR for three different radio configurations. Such configurations should ensure different reliability levels. | + | Start by identifying a set of five geographical locations or Test Points (TP). These TPs should be astutely chosen to explore the limits of LoRa coverage. Then, you should implement a function on the server that measures the ratio of successfully delivered packets or PDR.
