This is really big news!
From today on, a TTN Kerlink gateway is online on top of worldwide known "TV tower Berlin/Alexanderplatz" at height of 250 meters above ground level.
This will cover the whole Berlin City Area.
Maybe, signals also could be detected -in an experimental way- from Hamburg and Munich and also the Netherlands :).
A big big "thank you" to Marcus W. from www.digimondo.de who sponsored this "umbrella gateway" in a premium location for TTN Community Berlin.
Now Berlin has about 17 gateways on-line. Soon, some more will come.
