There are two timestamps along the transmission from to the device to the SIGFOX Backend:
- Timestamp #0: performed by the network when receiving the message
- Timestamp #1: performed by the SIGFOX Backend when processing the message
Message delay (seconds) = Timestamp #1 - Timestamp #0
High delay root-cause
A high device message delay might be observed if the device is covered by a single basestation and the latter has a temporary connectivity issue.
