Can multiple radios be used at the same time? E.g can intransit the same message over LoRa and NB-IoT/LTE-M
Depends what you mean by "at the same time" but I'm pretty sure you can queue one message for transmission via LTE and the same via LoRa. (of course LoRa will be the limitation due to limited packet size and airtime regulatory restrictions)
I'm also pretty sure - unless the team pulled off some miracle - that you cannot queue a message over LoRa and Sigfox at the same time because those two share the same chip.
Anyone can help??
