GSM Stumbler UI prototype screenshot
Here’s my first step at creating a user interface for my GSM Stumbler Windows Mobile application:

It’s very basic right now. All it does is pull out the phone’s currently connected cell tower and logs it to a text box on the screen. This data can also be sent via SMS or HTTP to my website to update my current location.
Also today, I created a PHP script to update my current Jaiku location. This isn’t in place yet, but I eventually intend to integrate this into my GSM Stumbler application. Future ideas include: looking up the location as human-readable format on the device, detecting multiple nearby base stations and their signal strength (for triangulation) and more Jaiku support.
Hi David - any plans on make the source code public?
The system currently relies too heavily on my website and my own tiny database of cell towers to be usable for anyone else yet. In the future I definitely see this being open source.
In the meantime, my code is based on someone’s work for a competition on the MoDaCo forums: “Create a component that can be used in a VB.net or C# (i.e. Compact Framework) managed application, to provide access to the Network Number / LAC / Cell ID / Signal Strength and such information from the radio layer of the device”
Thanks David!
We have done some work on this in the past - how accurate does

look?
We have a large database of CELLIDs and are working on an API at the moment - if you are interested?
hi david, id be interested to use your prototype code/app to update my webserver with LAC & CID information via http. im using google maps my location ‘api’ with a nifty reverse geocoding to get street, postcode etc
Nice one David. Just the sort of thing I’m looking for and I, too, would welcome the chance to use the app on an XDA Orbit running Win Mob 6.
We’re busy harnessing LBS with Demographics to create powerful solutions and this would do it!!
David, I would love to get my hands on some GSM Stumbler code, any plans on sharing?
