I guess not, but: is there any option in The Things Network to skip the LoRaWAN headers?
Like in a pet finder use case, one cannot send coordinates too often, due to the 1% duty cycle and 30 seconds/day Fair Access Policy. But even sending an empty “alive” message (for which a Class A node could then receive some specific reply to start sending coordinates) would take 1.16 seconds on SF12, for just the 13 bytes of the LoRaWAN header, hence would be limited to 26 empty packets a day…
Also location by triangulation would need some data to be sent. And some say moving nodes should always use SF12, though others have different experiences.
