-In this section, you will measure the Time on Air (ToA) as given by the time necessary to transmit a message on the radio interface. You will assess the impact of the spreading factor, the bandwidth, the coding rate, and the message size on the ToA.

-For this, you can start by implementing a function on the client that measures the time necessary for sending a message. For example, you can use the [[https://www.arduino.cc/en/Reference/Micros| micros()]] function available in the arduino libraries.

As we are in presence of variable experimental conditions, experiments should be repeated.

   * Describe the scenarios you used for assessing the impact of radio parameters on the ToA. You can join commented extracts of your code.
-  * Visualise the experimental results using for example [[http://www.physics.csbsju.edu/stats/box2.html | box plots]] of the ToA as function of the different radio parameters.

   * Analyze the obtained results and compare with the theoretical computations. You can superpose the theoretical results and the practical ones on the same graph.
