I tries doing this kind of thing at a hackathon once and we discovered that actual coordinate systems are hard to do. The "signal strength" data wireless cards produce are very dependent on the model of the devices involved. They're pretty unreliable for generating coordinates.
- matthewbauer 9y agoI feel like there has to be some sort of algorithm that lets you generate something like this though. You would definitely have to calibrate the RSSI based on your current card and time of day. Maybe not perfect but you could get a spatial sense of your routers.
- memmcgee 9y agoWell we were able to write an algorithm that kind of worked. But it relied more on just which MAC addresses are visible at a certain point.
