With KPN we are not using our own gateway.
I mentioned LMIC because of frequency mappings/channels. I know LoRaWan is a standard, but would not prefer a single channel solution, since porting that induces one additional step, namely multi to a single channel.
Thank you for your reply which of the two has your preference and why?
