- | ==== -. Coverage ==== | ||
- | In this section, you will measure the coverage of LoRa under different radio configurations. | ||
- | |||
- | 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 (Packet Delivery Ratio). Now, you should run the experiment for three different radio configurations: | ||
