How come my wireless heatmaps don't reflect obstacles?

I have built a map in OneView. I started with an image, and then traced drywall walls, brick, and glass. But I am finding that these walls do not seem to reflect any change with the signal when I choose to show coverage.

Whether the AP is inside of a concrete box, or hanging out in the middle of a big drywall room, the color map displays the same.

I guess I would expect there to be some sort of weakening of the signal, and a change in color when I am hitting brick or concrete. Is that not the case? Or perhaps I am not tracking something that I need to on my EWC?

Here is a screenshot of an AP that I have trapped inside of a cement wall. If I take the cement away, the signal coverage doesn't change.

Same issue.

Hi,
Are your map properties environment set to custom? If it is set to say cubicles or the office space, it wouldn't necessarily reflect what is drawn.

Example of me using a brick wall to limit wifi.

Aha! Changing to Custom did the trick for me. Now my maps have meaning!

Thank you Frank!
