Drawing Walls and Other Obstructions

To draw a wall or other obstructions (e.g., doors or windows) on the floor plan, press the wall drawing tool button and select one of the pre-defined wall types, for example “Brick wall” or “Interior office window.” You should select the type that best matches the actual wall you are going to draw. You can also select one of the two drawing modes: Line or Polygonal path. If you selected the Line mode, left-click on the floor plan to start a new wall and left-click once again in a new location to finish the wall. A straight line representing the wall will be drawn. If you selected the Polygonal path mode, left-click on the floor plan to start a new wall and left-click every time you need to start a new line segment. This will draw a connected series of line segments. If you hold the CTRL key while drawing walls, the line is drawn in orthogonal mode (0, 90, 180, or 270 degrees). To finish the wall, right-click on the floor plan or press the ESC key. You can move or resize the walls that you have drawn. To move a wall, select it and drag it with the left mouse button to a new position. To resize a wall or wall segment, select it, move the mouse over the vertex (shown as a white circle), click on it, and drag it with the left mouse button to a new position.

After the wall has been drawn, you can change its properties in the Obstruction Properties dialog. To display this dialog, double-click on a wall or select the Properties context menu item. In the dialog window, you can change the obstruction type by selecting one of the existing presets or modify obstruction characteristics such as attenuation, reflection, or color. Attenuation is a drop in strength measured in dB that the RF signal experiences when it passes through the obstruction. Because materials might attenuate differently at different frequencies, there are two separate attenuation values for 2.4 and 5 GHz. You can enter a custom attenuation value. A custom value can be obtained by measuring signal strength on each side of the obstruction and calculating the difference. Measurements can be performed using TamoGraph or any WLAN analyzer, e.g., CommView for WiFi. Reflection is a percentage of signal strength that is reflected by the obstruction at the 90° angle. Color is an arbitrary color used to show the obstruction on the floor plan. If you prefer obstructions to appear colorless (i.e., grayscale), you can configure the application to grayscale them in the Visualization Settings panel. When you have edited obstruction properties, you can save the current configuration for future use by clicking the Save as Preset button at the bottom of the dialog window.
