Specifying the RF Characteristics of a Floor 99
3 In the Attenuation Factor boxes, specify the attenuation factor for
802.11a and 802.11b/g technology (0 to 100 dB). The default is the
typical attenuation factor for the material chosen.
4 Click Finish to save the changes and close the dialog box.
„
If you created RF obstacles for all objects in a layer, all objects in the
layer are converted into separate RF obstacles.
„
If you created RF obstacles for an area, all objects in the area are
converted into separate RF obstacles.
„
If you created RF obstacles for multiple selected objects, all objects
you selected are converted into separate RF obstacles.
„
If you created RF obstacles for grouped objects, each grouped
object is converted into a single RF obstacle.
Drawing RF Obstacles
1 Display the floor plan in the Content panel.
2 In the Task List panel, click Tools.
3 In the RF Obstacle area under Layout, click one of the icons and draw the
object as described in the following table.
Object Action
(circle)
Diagonally drag the cursor over the area where you
want the circle to appear.
(square)
Diagonally drag the cursor over the area where you
want the square to appear.
3WXM treats squares as one solid object when
calculating RF attenuation. To draw a square outline,
draw four lines in a square shape, which are treated as
four separate RF obstacles.
(parallelogram)
1 Click at a vertex, and drag the cursor to the next
connected vertex.
2 Click again, and drag the cursor until the
parallelogram takes the shape you want.
3 Click to finish.
