I want to build a simple iOS Application with iBeacons.
I have four iBeacons and my goal is to calculate my room position by doing Trilateration. I want to show the room on the display, set the fixed positions of the iBeacons and then calculate the Position and show it on the display.
My problem is, I don't know how to start.
Even though iBeacons are relatively simple to use, trilateration done with them is far from that. The standard is meant for simply determining your current location zone from the nearest beacon. The zones are: immediate (0-0,5m), near (0,5-2m), far (2-20m). Due to the instability of the signal, it is difficult to obtain more precise location data.
That being said, there are a couple of companies that I know, who have worked with that issue: Estimote (Estimote Indoor SDK) and Steerpath. Maybe looking at those two solutions could help you get started with your project.
