-In this section, you will measure the Time on Air (ToA) that is given by the time necessary to transmit a message on the radio interface . You will assess the impact of the spreading factor, bandwidth, coding rate, and message size on the ToA.+In this section, you will measure the Time on Air (ToA) that is given by the time necessary to transmit a message on the radio interface. You will assess the impact of the spreading factor, bandwidth, coding rate, and message size on the ToA.
  
 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. Now, you can modify one of the parameters (spreading factor, bandwidth, coding rate, message size) and record the impact on the ToA. Note well that you may need to repeat the experiment multiple times in order to obtain the statistical distribution. Start by implementing a function on the client that measures the time necessary for sending a message.
