First glimpse of worldwide cell phone coverage

Thanks to 700 iPhone logs we now have data on 2.1 million mobile phone network cells.

Note 1:
The colors indicate the density of surrounding network cells. They do not show the range of the cell towers.

Note 2:
The results are preliminary since our database is based on only 700 iPhone logs … yet.
So please donate your iPhone logs too!

    hmm, I wonder why there are just 700 participants…
    I thought more of the geek culture…

    @Pit – Because, while geeks classically enjoy interesting stuff like this, they’re also, as a group, paranoid about giving out their information. Note I say this as one of the 700 that donated my logs ^_^

    Is there an updated database dump of GSM towers and Wifi? Where to get the current version?

    Is there a way to access the database? or you are planning on releasing dumps every few days?

    Where exactly is the facebook like button ?

      The Facebook like button is somewhere in the middle of the front page. We should probably move the button to a more prominent place …
