Yes, synchronization would be ideal. However, keep in mind this is to identify people with phones in their pockets walking on a sidewalk. From the GPS signal of my 3+ locations I'll get also accurate timing. By getting power readings that are "close" I expect to have some error indeed, but that should be well within the accuracy of the power readings anyway. Having that said, this discussion seems to slowly confirm my fears that there is no ready solution for my problem. Is that so?

Here are a few projects that people put together to do something similar to what I'm looking for: http://mw2013.museumsandtheweb.com/paper/3817/ http://atrf.info/papers/2013/2013_abedi_bhaskar_chung.pdf

Hallo Cooper, Thank you very much for your reply. I saw how you and toughbunny discussed hard on the topic and indeed it drifted a bit as you were doing for the sake of the experirment. In my case, I have a more specific question and I know it is pretty straight forward. Additionally, based on my research on the topic, I would be really surprised if nobody ever built anything like that. Thus it is, in my opinion, not a matter of capability, but of knowledge of projects and technologies. I'm trying really hard to avoid reinventing the wheel and hope to find some folks who know the tricks to get the job done!

Hello all, I've been looking for a way to setup a few wifi antenas in listening mode, capture "events" with Kismet then compile the information to give me with some idea of how many wifi devices were in the area as well as have some indication of their locations. To to that I expect the algorithm to do pretty much the reverse of a Wardrive. I imanine 3 or more wifi devices in listening mode. Each one of them with a GPS location. They would, using Kismet, log MAC addresses, with power level and time stamp. An algorithm would get the 3 GPS locations, get each of the MAC addresses, try to match time stamps and interpolate/triangulate positions. I've seen results of such algorithms that track crowds as well as individuals. However, I haven't been able to find a library that does that. I hope there are some knowledgeable folks out there who know where should I be looking.
