How accurate can the location triangulated between iBeacons be? #iBeaconWebinar

I am curious how accurate the location of a stationary client can be derived when triangulation is performed inside a set of iBeacons, assuming an optimally calibrated environment. Is there any information available about this?

In ideal environments in relatively small venues triangulation and trilateration can be pretty effective.

Unfortunately in larger environments, in real world conditions, this becomes pretty unreliable.

One of the reasons why proximity has gained so much popularity is that, in it's simplicity, it offers reliability and repeatability, even in relatively challenging conditions.

Hey Nick,  it's been a while.. 

My thoughts on location is .. it shouldn't matter.  It's about the "context" of info presented, beacon string or UUID in this example, to trigger something else. 

Using other apps as example e.g. IFTTT, Android Trigger and so on.  Some day I will think of a purpose for Yo.

My 2 cents.

The accuracy depends on how close you're getting to the beacons.  In another thread, super-star champ David Helms pointed out that the accuracy is range-dependent and gets better the closer you are.  If you're willing to deploy lots of iBeacons, you'll get better results -- but you still need to map the iBeacons into a coordinate system and physical space accurately enough to make sense of the proximity vectors you get.  Triangulating on to a map is much more advanced than triggering on the proximity context.

We've done some characterization of RSI to range -- close in it tracks pretty well, as you get further away multipath and other effects can introduce a lot of errors. The geometry of the space your in has a big effect.
