Triangulate example for iBeacons

Question

I am looking into the possibility to use multiple iBeacons to do a \'rough\' indoor position location. The application is a kind of \'museum\' setting, and it would be easie

Answer 1

We are also trying to find the best way to precisely locate someone into a room using iBeacons. The thing is that the beacon signal power is not constant, and it is affected by other 2.4 Ghz signals, metal objects etc, so to achieve maximum precision it is necessary to calibrate each beacon individually, and once it has been set in the desired position. (and make some field test to see signal fluctuations when other Bluetooth devices are present). We have also some iBeacons from Estimote (the same of the Konrad Dzwinel's video), and they have already developed some tech demo of what can be done with the iBeacons. Within their App it is possible to see a Radar in which iBeacons are shown. Sometimes is pretty accurate, but sometimes it is not, (and seems phone movement is not being considered to calculate positions). Check the Demo in the video we made here: http://goo.gl/98hiza

Although in theory 3 iBeacons should be enough to achieve a good precision, maybe in real world situations more beacons are needed to ensure the precision you are looking for.
