OpenCellID (was OpenBmap logger (GSM positioning)])

Fri Feb 20 16:35:51 CET 2009

  Dear OpenMoko community (and thanks ed for pointing this out).

  I am behind the opencellid.org project, and it seems that there are some
discussion around it these day on the mailing list.

  So let me clarifiy:

- As described in the web site, the license is under creative common share
alike 3.0. I had several request today stating that just linking to the
license was not clear enough, so I will re-clarify it on the web site, but
also in this list.

- I am surprised to see statment that I did not answer to some questions.
I've verified,and all openmoko request have been answered. I am not perfect,
and may be some emails have been missed, but a search on openmoko on my mail
box did not raise any pending question.

    There is more than 100 000 cells covered, with 5.5 millions of measure,
and more cells will be "donated" soon. We expect to reach 200 000 cells in
the coming weeks thanks to a new project donation. There is also more than
10 different clients (windows mobile, symbian, blackberry, j2me,...)
gathering the database.

  I've been running this project since more than one year , with an
objective to push community efforts around cell id. So I would be more than
happy to see new effort joining this project instead of creating separate
efforts.  So let's join effort and create something big!

 And as a reminder, the complete data base is available for download.

 So if you have any question/interrogation, feel free to share them with me
so we can clarify this.

 Regards,
