LoRaWAN in the future.... What's in the pipeline today?
Most promising is a dev-2-dev communication upgrade, so up to 16 nodes will be concentrated by an extender... could be used for satellite communication, or also facilitiy management i think. Very exciting developments....
Have a look at this interesting video by the godfather of LoRaWAN @semtech :) :
