Wow! This is really big news!
Today TTN Berlin initiated a continuous mapping survey via www.ttnmapper.org of the whole inner city area of the german capitale.
3 mobile nodes are on it's way 24hrs/day in a taxicab and in 2/shift drivers. Soon we expect some more activities.
So we will get, step by step, a broader picture of LoRaWAN signal propagation and reception in our metropolis.
This demo could be an example other communities may copy - free of charge :) - .
A big thanks to Klaus from Berlin TTN Community!
