Hello Wyko,



Apps that are ranging in a beacon region will be returned an array of currently detected beacons.

The app can iterate over that beacon and compare the distance to the beacon as a means to determine the closest beacon.

In an open environment, what is the accuracy of the signal?

Wyko,

Accuracy tends to be greater the closer you are to the beacons and to decrease as you get farther away. At less than 1m, you will see variations from 0.1-0.2m. At 10m away, you will see variability (in rough terms) of 1-2m.

And these numbers are much more accurate than you can get with other readily available technologies.  There are some in-the-lab developments for Wi-Fi that might get close when you have line of sight, but a Wi-Fi AP will always be more expensive than an iBeacon.
