There are limitation to do with the Duty Cycles in LoRa networks which we've found inhibits certain real time applications. It effectively limits the number of "messages" you can send during a specific time frame.
We go beyond LoRaWAN with our own protocol for some use cases.
For those following along: LoRa is a wireless encoding technique (PHY layer), LoRaWAN is a protocol for how a large group of devices should structure their packets (MAC layer).
The FCC limits time spent transmitting in a single channel ("time on air"), but there's no duty cycle limit if you follow the channel hopping rules.
