Wrong tag coordinate at specific location


I am using 4 anchors in a room with dimension 8 x 3 m. Anchor coordinates are measured and configured properly.

As I move the tag in a straight line parallel to X axis, I would expect the Y value to fairly remain constant with few cms fluctuation. As I traverse through the line, somewhere in the middle suddenly the Y value increases by about 30 cms . As I continue further, Y value settles down to expected value. This phenomenon is consistent.

Any thoughts on possible reason for this strange behavior. FYI, there is no interference and LOS is guaranteed throughout.


Could you tell us what you’re using? MDEK1000, TREK1000 , or own developed hardware?

I am using MDEK1001.
