I want to define an area with a certain number of beacons. Theoretically it should be possible, Is it possible practically? Because the distance value that i get fluctuates erratically.
Do you mean that you'd want to figure out an exact position of a person based on trilateration from multiple beacons in the area? Like you said, it is quite hard with the sporadic signal transmission. There's some SDKs that exist for this, such as the Proximi.io free SDK and platform (http://proximi.io)
