I am trying to use beacons to set a squared region at outdoor open space to get respective position (up-to 1 meter accuracy) once I enter that region.
I didn’t re-implement trilateration because I believed that indoor location SDK already took care of it.
And the reason that I am using beacons instead of location data is that I need to get data that has lower horizontal accuracy than 5-8 meters.
I have tried using 8 beacons with various set-ups: 20x20 meters, 20x15 meter, 15x15 meters, 40x40 meters, 10x10 meters. All the beacons had intervals around 190-200 ms and power with 4dBm.
For 8 beacons: I set 4 of them at the corners and the other 4 in the middle of each wall. (used indoor location builder)
It seems like 8 beacons with 20x20 meters worked the best (I don’t know why 10x10 didn’t work better than 20x20 though), but I still want to reduce noise and inaccurate data.
For example, it lost track once I started running or walking fast within the region.
Also, sometimes it needed 3-10 seconds until I get the position.
I am wondering how I can get better accuracy: should I add more beacons or reduce the interval, or is there anything that I am missing?
I look forward to hearing from you.
