I spent around 2 hours driving around the city doing some coverage tests.
The current area coverage (with only 2 gateways installed and working round the clock) looks very promising so far. Most of the city center and part of the riverside area seem to be covered already.

I was surprised to achieve almost 4000 meters distance with such terrain level differences within the city.
Where should the 3rd gateway be installed?
