Walls
iBwave Design allows you to add walls onto your Layout Plans using 3 different
methods:
1. CAD file import (Prediction, Import Walls) 2. Image file import (or pixel converter)
(Prediction, Import Walls) and 3. free-hand drawing.

€ Import .vex File
In order to be able to define walls on the Layout Plan, users need to import the vex file
for Propagation into their database.

.vex import is
done in DB
Editor.
1. Click on
Import under
File.

2. Choose the
.vex file for
Propagation.

3. Click Open.

1. Open DB Editor.
2. Go to File/Import.
3. Locate the .vex file for Propagation. If you do not have this file, you can
download it from www.ibwave.com/myibwave.aspx > downloads
4. Select the .vex file and click open.
5. Once it is loaded, close your DB Editor and it will prompt you to save. Click on
‘Yes’ to save the changes.
6. Go to iBwave Design and update your database under Tools/Update Database.

Make sure the .vex file for propagation was imported to the database.
Create an empty Layout Plan.
Go to Import walls under Prediction Menus at the top most toolbar.
A window will pop up to prompt you to select a CAD file to be loaded.
Select the .dwg file and click open.
Once it is loaded, you will be able to see a window where you can select
different layers to be displayed.
7. Unselect the layers that are not required. Choose the ones representing walls.
8. Depending on the previous layers selected, the user will be asked to define
each layer or all layers with a material in the database.
9. After clicking ok, you will be asked to specify the height of the 2D walls either
per layer by entering the height and pressing OK or for all layers by entering the
height and pressing OK, all layers.
10.By clicking import, it will transfer the selected layers to iBwave Design.
11.A Layout Plan with all the defined walls will be displayed. Scale the plan
accordingly using the Ruler.
12.Imported walls will be proportionally stretched to fit the plan.
13.Once the walls had been imported to the Layout Plan, scale it accordingly.
14.You can start placing the antennas and components on top of the Layout Plan.
15.Once you finish the design, go to Prediction Properties under Project Properties.
16.In the Prediction Properties, you can define all the prediction parameters
accordingly, as well as the prediction setting to suit your needs.
17.Once all the settings are being made, go to Output Maps Configuration in the
Prediction Panel to create the type of output maps you would like to have.
18.Once all the maps are created, click on the Predict icons on the Prediction
Panel. You can choose either to predict the Layout Plan one at a time or the
entire project.
19.After the prediction is done, enable the Prediction/Indoor check box under the
Prediction Panel in order to display the results for the desired output maps.
20.You can display the Prediction Legend by selecting the legend icon in the
toolbar and place it on the Layout Plan.
21.To customise the legend, simply double click on the legend and it will bring you
to the color schemes.
22.You can customise your own legend according to requirement or you can
choose from the default legend.
23.If you would like to know the signal strength at a certain area, enable the signal
probe checkbox in the Prediction Panel. As you move your mouse across the
Layout Plan, it will give you the signal strength reading accordingly.
24.The prediction result will be saved automatically once you save your project file.
* A height of 0 is equivalent to selecting ‘Ignore all 2D objects’.

Once walls are imported into iBwave Design, you will be able to remove unneeded
layers from your Layout Plan using the Wall simplification tool.

9. Once all walls are associated with
the proper material, you can Lock
size and position of all walls.

10. If required, you can now associate

1. Select a material from the
Draw walls drop-down list
contained within the Prediction
toolbar

2. Once in wall drawing
mode the mouse
changes to a cross. You
can start drawing walls

3. Left click where you
want to begin a wall

Clicking the button will select
the first material from the list.
To select a specific material,
click the arrow to pull-down a
list of all materials. The three
most recently used materials
are at the top of the list

5. Repeat step 4 until

1. To end the drawing process, double-click
instead of left-click at the last inflection
point location or use the enter key or
right-click the plan and select Enter from
the menu

4. Move the mouse to the
next inflection point
(corner) of the wall. Leftclick to create the
inflection point

When drawing a wall manually, various operations are available. To access
these operations, simply use the keyboard shortcuts or right-click the plan and
choose from the following menu:

- Enter Key or Double-click: Stops current wall drawing, and stays in wall
drawing mode.
- Cancel or Esc Key: Cancels current wall drawing.
Remove last inflection point or Delete key: Removes the last wall corner drawn
- Snap at wall corners or F9 key: When approaching an existing wall corner, the
mouse pointer will be attracted to it and display an orange square around the
corner. If you left-click, your newly added inflection point will be positioned at the
existing corner.

- Snap on walls or F10 key: When approaching an existing wall segment, the
mouse pointer will be attracted to it and display an orange X on the segment. If
you left-click, your newly added inflection point will be positioned at the X
marking on the existing segment.

- Snap on grid or F11 key: When you left-click to draw an inflection point, the
position of the new point will be aligned to the grid.

- Orthogonal extensions or F12 key: When Orthogonal extension is turned on,
only horizontal or vertical walls can be drawn.

Wall Heights
Once your wall has been imported into iBwave Design, you have the possibility
to go back and change their heights. This can be done if the specific height
were not specified on the imported material that was used for your wall creation.

This value will
specify at which
height your Wall
will start from. (0 if
from the ground)

This will overwrite
the default values
in your Prediction
Properties
This value will be
the highest point
on the wall near
the ceiling

21


Objects
To simulate three dimensional objects in iBwave Design, you will need to create
objects that can represent floors or real objects.

1. For example in a 3D
prediction you would
need to create a floor
as an object

2. The next step
would be to create
your floor on the
layout plan

22


Wall Holes
If you want to simulate scenarios such as an atrium in a building you can create
holes (using using “Air” as the wall material) on top of the existing object to
simulate an opening.

1. The first step
would be to create
your horizontal
surface (floor) on
the layout plan

2. The next step would
be to create a “hole” on
your floor plan to
simulate the opening
using “Air” as the wall
material and drawing
that on top of the
horizontal surface.

23


Inclined Surface
To simulate objects such as staircase in iBwave Design, you will need to
create objects that can represent floors or real objects with different height at
both ends. Inclined surface can be use to defined such area.

2. The next step
would be to create
the surface on the
layout plan.
1. Click on
Inclined Surface
icon on the
Prediction toolbar.

3. Right-click on the
surface and select Set
height for selected
inclined plane.

4. Move the cursor to
set the desired height.
6. Click OK
when Done.
5. Check this option like
to see the height on
Layout Plan

24


The arrow shows the
direction of the Inclined
surface.
The height of each end
is shown on the Layout
Plan

Frequently Asked Questions
Q: Why was I unable to draw walls?
A: Make sure that you have imported the .vex file for Propagation. If you just imported
the .vex file, update your database before using Draw Walls.
Q: Why does the prediction result not turn out as per expected.
A: The accuracy of the prediction results are based on how well the layout is being
modeled. Make sure you have define all the necessary walls before running the
prediction.
Q: Why are there no prediction results being displayed?
A: When this happens, there are a few ways to double check it.
• Do your transmitters have power?
• Is the Layout Plan's scale set?
• Is the prediction check box in the data view filter checked for your system?
• Are there errors present in the debug message list that could affect your
prediction?
• Does your prediction color legend cover the range of signal you expect? Use
the prediction probe from the data view filter to check.
