Thanks! You may try increasing the broadcasting power of each beacon to get better accuracy. Also, we're working on our Android SDK so please stay tuned.

Hey, I'm Lukasz, CTO at Estimote, I'd love to take a look—please drop us a line!

Email sent!

Thanks! Capabilities live up to the design, at least :)

Also, here's a short video showing what's possible: http://www.youtube.com/watch?v=SrsHBjzt2E8

Nice! Should be in the article BTW.

For a global overview of startup locations you can also take a look at http://startup-map.datalysed.com

Thanks for the link. Good idea to group the startups by area, this solves the marker overlapping problem. Does it only display the number of startups or can you also list startup details?

very interesting. Is there a way to find the company names and addresses?

In addition to cell tower and Wi-Fi hotspot locations iTunes keeps a backup of all text messages and recent calls. A while ago I've even made a small web app to chart it - http://datalysed.com/?p=130
