From late December 2016 we had our first #TTN LoRa Gateway up and running. Followed the DIY path using a RaspberryPi the IMST iC880A concentrator board and the LoRaWAN code repo on github and of course the wiki.
We have already deployed various apps in the TTN console and there is an active integration with Azure & Node-RED. TEAM members of TLab have undertaken the task of testing and deploying various open-source sw/hw technologies bringing IoT closer to reality!
And yes! #LoRa already has great coverage in Thessaloniki :)
