Accuracy is all a function of AP density. If you're going off of triangulation alone, you're only going to be as accurate as your APs are dense. If you're looking for higher accuracy than that, you're going to need to consider an overlay of additional monitor mode APs or a separate location based system.
Cisco has an angle of arrival location module that looks slick if you're using a Cisco system with 3600/3700 APs or willing to upgrade. I'm sure other companies are working on similar products as well. With all of that said, to go from some box having a good idea of where a device is at to something useful to a business is a big leap. Out of the box there seem to be good solutions for bulk crowd counting ala retail or transportation. Anything beyond that is likely going to be some custom solution either home grown if you've got programmers (Cisco and Aruba have fairly open APIs for their location boxes), or from an integrator. -Luke On Wed, Apr 22, 2015 at 12:07 PM, Cosgrove, John <[email protected]> wrote: > Well the next level of resolution from that is “Swing a dead cat” > radius.
