I had some time earlier and did some research and learned a few things, but I had one idea on how triangulate a wifi. Any way that you could use three usb radios and karma and just calculate it based on the microtime of the computer in which the signal was received? The goal is not a missile guidance system so the resolution doesn't have to be great, just enough to give the pineappler a fair gauge of where the ap or client he/she is in relation to the pineapple. I have this image stuck in my head of a radar screen with little pineapples to pin the locations of APs...

It is my understanding that you can triangulate any signal as long as you have at least 3 radios to pick up on it and you have to sync up each of the triangulating radios timer chips with each other.

I haven't had a chance to look into it yet to satisfy my curiosity but I figure you can do it somehow using a microcontroller and linking it to all the APs UARTs or something. Just thought it would be cool to have a 'radar' screen of hotspots.

Hey All, Just curious, has anyone every tried using three of the mark IVs (or whatever combo of 3) to triangulate an AP? I worked on a project a couple years ago with a little robot that was controlled via wifi, and in the design phase the idea on how to tell the position of the robot was to triangulate it using four routers positioned around the room and to calculate it based on the timing of the signal received at each AP. But it became clear that it would be extremely challenging to calculate it within any degree due to difficulty in syncronizing all four APs timers and precise placement of them (not withholding a laundry list of other technicallities due in part to the distance of each AP to one another). But if the APs were placed in a single enclosure and then the antennas were placed X distance apart from each other, would it be possible to sync them up to be able to triangulate another AP signal? I've seen similar posts in the car computing forums where people were getting together to use police scanners to triangulate police cars and pinpoint them in a GPS mapping program. Never returned to see how far they got with it though...
