You should save the direction the antenna shows into. I had a look at the gsm antennas in my region and there are always 2-3 fixed on one tower. Each of them show in their own direction and have a different CID. At my home I'm often connected to a tower which distance to me is bigger than the distance of another tower - though the further afar tower is oriented almost directly to my house and the other one is not. In your data the 550m distance steps to the antenna is also not used as far as I have seen it. This is important data! P.S.: In my opionion it would be nice to have this data in OSM, too. There are already the towers for electricity (gsm antennas are often fixed on them in Germany (at least in Oldenburg)) - And one can easily get them out of the data again. -- Sebastian Reichel
