5.1 Editing Wall and Floor Libraries

he properties and settings of wall and floor materials are stored in the library. You can
easily edit and expand this library. Each type of wall or oor is saved in a separate XML
file. These files are contained in the folder RF3DWifiPlanner/WallsFloors.
The names of the wall and floor files must follow certain rules in order to be recognized
by the RF3D WiPlanner program. Example: ft_003_6-_Brick_7_18dB. The le name must
begin with ‘ft’ or ‘m’ to indicate whether this wall or floor is defined in feet or in meters.
The wall or floor is then available in the Toolbox only when the same measurement
unit is selected in the program options. The next part of the file name after the meas-
urement unit abbreviation is an underscore followed by a three-digit number. This
number determines the position at which the given wall or floor type appears in the
toolbox list. After another underscore comes the name you want to use for this wall or
floor type.
The best way to create a wall or floor type is to find a file that defines a similar, existing
type, open it in Notepad, and save it under a new name before editing its contents.
The lines you can edit are explained with examples below.
The Type line defines the name displayed in the Toolbox.
<Type id=“ref-4“>6“ Brick 7/18dB</Type>
The DampA_dB line indicates the signal attenuation through such a wall or oor in dB
in the 5 GHz band used for 802.11 a and h networks.
<DampA_dB>7</DampA_dB>
The DampBG_dB line indicates the signal attenuation through such a wall or oor in
dB in the 2.4 GHz band used for 802.11 b and g networks.
<DampBG_dB>18</DampBG_dB>
The GaugeFeet line indicates the thickness of the wall or ���oor in feet. If you enter a
non-zero value here, you should enter zero in the GaugeMeter line below.
<GaugeFeet>0.5</GaugeFeet>
The GaugeMeter line indicates the thickness of the wall or oor in meters. If you enter
a non-zero value here, you should enter zero in the GaugeFeet line above.
<GaugeMeter>0</GaugeMeter>
The knownColor line defines the color in which you will draw the wall or floor in the level
plans. For permissible color names, see the table in Appendix c.
<knownColor>142</knownColor>
The IsFloor line determines whether the building element described in this file is a wall
or a floor. If IsFloor is true, it’s a floor. If IsFloor is false, the file describes a wall.
<IsFloor>false</IsFloor>
If you have edited a copy of an existing library file, you must leave all other parts of
the file unchanged. Otherwise, the program may behave unexpectedly.
