To find information about a gateway, using the gateway ID:
https://ttnmapper.org/colour-radar/?type=radar&hideothers=on&gateway=eui-0ba0000000000001
https://www.thethingsnetwork.org/gateway-data/

To find information about a gateway, using the latitude and longitude:
https://www.thethingsnetwork.org/gateway-data/location?latitude=52.46079&longitude=4.800586&distance=200

End node located at the 2nd floor (altitude ~11m):
https://www.google.nl/maps/place/52°27'06.2"N+4°48'39.7"E

The end node tx power is not reduced!
The end node is placed in front of a window at location A, facing East and South.
