I have now joined The Things Network community here in Copenhagen with my own gateway and is now helping cover a little bit of the greater Copenhagen area with wireless network connection for small IoT devices based on the LoRaWAN technology.

i have decided to build gateway using an APU2 from pcEngines and an n|fuse LoRa concentrator card and I have written a small guide on how to set up the machine and software. This is just about the gateway and the first part of it is a more general setup guide for the APU2, where the later part will most likely also work on other hardware.
