iBeacon Trilateration and showing user's position on a map iOS -

-

i want build simple ios application ibeacons.

i have 4 ibeacons , goal calculate room position doing trilateration. want show room on display, set fixed positions of ibeacons , calculate position , show on display.

my problem is, don't know how start.

even though ibeacons relatively simple use, trilateration done them far that. standard meant determining current location zone nearest beacon. zones are: immediate (0-0,5m), near (0,5-2m), far (2-20m). due instability of signal, difficult obtain more precise location data.

that being said, there couple of companies know, have worked issue: estimote (estimote indoor sdk) , steerpath. maybe looking @ 2 solutions started project.
