Look at retail wifi uses throughout the country.
Large retails have the capability of tracking individual users through their cell phone.
Register that number with the retailer, and they can tailor coupons to you.
From what I understand, it takes a robust infrastructure, and the APs aren't exactly cheap.
I suspect it is not so much triangulation, rather tracking AP range, and where the user connects, and spends the most time connected to individual APs.
I've see it in articles - but never paid attention, as it is out of my budget; mission scope; and service parameters for offering wifi for browsing.

Yeah, This article (http://journal.code4lib.org/articles/5859) talks about locating and tracking staff in a library, but it uses Androids with a phone app built for the purpose.

I am sure that there is some utility library to do this, but it would need to be incorporated in an app and loaded on the user side.
