The figure below highlights the timing of the events:
Figure 6: Power Consumption Across Time
Tx duration is
SF dependent
The Rx Window 1 is opened exactly 1s
after the end of the Tx
The Rx Window 1 is opened for
5 symbols at SF12.
The Rx Windows are 5 symbols at
SF12. Depending on the SF, the Rx
Windows are thus changing.
Delay between Tx
Sensor power
consumption
(duration and
power consumption
is sensor
dependent)
The Rx Window 2 is opened exactly 2s
after the end of the Tx if no packet was
received during the first Rx Window
