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.
