-In this section, you are required to establish a record of LoRa coverage. You can certainly unleash your scientific imagination, but some rules must be followed to validate the record:
+Start by identifying a set of three 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: such configurations should provide different reliability levels (high, medium, and low reliability).
+<WRAP center round help 100%>
+  * Draw the test points on a map and motivate your choices.
+  * Describe the radio configurations you selected and their impact on the reliability of the transmission.
+  * Visualise the experimental results by plotting the PDR for each TP and each radio configuration.
+  * Analyze the obtained results.
