2. Area analysis

Area analyses are designed to visualize measurements and network conditions and to aid in theidentification of problem areas. There are two different types of area analyses depending on thecollection device: phone-based and scanner-based. The dialog for each area analysis has one Generaltab. The Generaltab contains common parameters used in all area analyses.

The Generaltab has the following configuration parameters:

Report name specifies the report name. This name is used as a prefix for all maps and tablescreated by the analysis.

Data selection specifies following parameters:o File type specifies the type of data source. There are two possible file types: Original

and Merged (dynamically). Original files refer to data converted by the File converterutility. Merged (dynamically) refers to files created using the Dynamic merge utility.

o File specifies the devices to be analyzed (one or several devices can be selected foranalysis at the same time).

o Workspace specifies the name of the workspace that will be used to store the results.If a nonexistent workspace is specified, the analysis will automatically create the newworkspace using the specified name.

Input parameters contains generic parameters used by the analysis, such as Systems andVectors.

The parameter values can be saved by clicking Save valuesor loaded from a previously saved file byclicking Load values.

Typical area analysis configuration window is presented in Figure 2.
