Tja! Yesterday we did a run with the TTNMapper to check the coverage of our first gateway. We could achieve several connections around 6-7 km away from the gateway. Thats a great result! But sadly the hills to the south are blocking the signal, so that we have no connection in the city itself... The second gateway is ATM just placed indoor and the third one is still on the workbench waiting for some soldering. So we are actually looking for some good spots to put up the gateways to achieve some coverage in the city center. Any help in that department would be very nice!
