Hi,
as we are part of The Things Network, you can use our LoRaWAN network and services through https://www.thethingsnetwork.org/. You will also find documentation etc. for running LoRaWAN Gateways, Sensors, and Projects there.
We are looking forward running TTN Stack v3 in Vienna as soon as a stable release is provided by TTN. It’s expected during Spring 2019. But this won’t change your setups too much if you are thinking about LoRaWAN projects. The stack is running in the background.
For additional services (running more sophisticated applications hosted on our systems or analyze platforms etc.) we are preparing more information, as @Bernhard says.
BTW: the next chance to participate is the Community Meeting on 9th January (https://openiot.network/2019/01/community-meeting-9th-january-2019/) and the Gateway Workshop (Gateway Workshop - Doodle now available!).
