We have deployed two LoRaWAN Gateways on top of the big former coal mine tower in the center of Kamp-Lintfort. The gateways with two antennas each are located at the south-west corner (aka south) and the north-east corner (aka north) of the tower's balcony.

The gateways are part of The Things Network (TTN).

The two TTN Mapper views below show some range tests for the two gateways.
