I have to work-out the license issue as you mentioned. I really started from
the OSM one...
even if I have seen all the discussions about it.
I am ready to consider all the solutions to solve this license problem.

When I started http://www.openBmap.org and until a few weeks ago,
there was no mention about the data license on opencellid website.
(and impossible to reach them...)

The other projects mentioned on


did not mention their license too.

As the logo creative commons appears now on the opencellid website, I have
to import their data in my database. I will still able to erase their data
if needed...

Anyway, it will help me to raise scalability issues and define  if needed
another design
for the mapping manager database.

Thanks! and please have a look at the following url for zones in Germany

(please zoom out on Google maps to see Germany coverage for O2 operator)

1) the CC license seems "all new" to opencellid.org
2) the way to calculate cellular "average" position and attributes are not
the same...
3) the signal strengths are not stored at opencellid.org side

I 'll wait a little before considering a merge.
