Selecting Data for Analysis

Three key interface elements affect what data will be analyzed and how. These elements are overviewed below.

The Plans and Surveys tab on the right panel defines what data the application will visualize. This tab is organized as a hierarchical tree, where for each floor or site plan, you will see one or more site surveys you have conducted.  You need to select the floor plan to be analyzed and mark one or more survey paths to be included using the corresponding checkboxes. Depending on where and when the surveys were conducted, you may want to check all or only some of the survey checkboxes. For example, if you have a large site and you made one break while conducting the site survey, your walkabout path will consist of two parts, both of which should be included in the analysis. In a different scenario (e.g., if you surveyed the entire site prior to installing additional wireless hardware and then surveyed it again after the installation), you will probably want to include only one of the surveys and then compare it with the other by changing the checkbox selection. The Type column indicates the survey type: Active, Passive, or Active+Passive. We are reviewing active surveys in this chapter, so you should select the surveys that are marked as Active or Active+Passive in this column. You can use the Comments column to add or modify comments for surveys or modify the survey names for clarity at any time.

The Visualization drop-down box on the tool bar defines what type of analytical tool will be applied to the selected site plan. A visualization is a graphical representation of WLAN characteristics displayed as an overlay on top of the floor plan. The available visualization types will be described below. To select a visualization, simply select the corresponding item from the drop-down list, under the Active section. To clear all visualizations, select None. When no visualization is selected, the floor plan is overlaid with the walkabout paths and guess range areas (the zones within which TamoGraph can make a good assessment of the WLAN parameters).

Unlike passive surveys, active surveys do not include information on the APs in the survey area; they are focused on the specific WLAN or AP to which you connected during the active survey. For this reason, the Selected APs / All APs buttons on the tool bar are disabled when you select a visualization for an active survey. The AP list might still be available if you also performed a passive survey or if APs can be currently “heard” by the application, but checking or unchecking the boxes next to the listed APs has no effect in this case.
