2 Basics

2.1 Import of Urban Databases

Before computing predictions, at first the urban database representing the area of interest has to be imported into Atoll/9955 RNP. This can be achieved by the File



Import

menu where the corresponding MapInfo file has to be selected (please refer to the Atoll/9955 RNP manual for details concerning the import functionality). While the MIF-file represents the polygons of the buildings the MID-file stores the individual building heights (MapInfo ASCII format). Both files can be generated within WallMan by saving the loaded database in the MapInfo format.

Fig. 2-1: Visualization of urban building data

After this the urban database is visualized if the check-box belonging to this database is switched on. This allows the convenient definition of the computation zone and/or focus zone taking into account the structure of the urban building database (concerning the definition of the computation zone and/or focus zone please refer to the Atoll/9955 RNP manual for details).

2.2 Definition of WinProp Parameters

Before selecting WinProp-IRT or WinProp-UDP as propagation model for one or several transmitters all the prediction parameters like output, database, propagation model settings, hybrid model settings have to be defined. You will find the property pages of WinProp-IRT or

WinProp-UDP

like any other propagation model under the Modules tab

of the Atoll/9955 RNP Explorer.

Fig. 2-2: General page of the WinProp property pages

In order to allow the convenient parameter definition all the available parameters are arranged in different property pages (as indicated in the figure above):

 General

 Output

 Prediction

 Database

 Post-processing model

 Parameters (for standard propagation model)

 Clutter (for standard propagation model)

All settings are already set to suggestive values by default. A detailed description of each property page will be presented in the following chapter.

While most of the parameters for the propagation calculation utilizing WinProp-IRT (or

WinProp-UDP

) have to defined on the above mentioned property pages, the grid resolution as well as the receiver height are defined on the prediction property page under the Data tab of the

Atoll/9955 RNP Explorer

. These two parameters and the extension of the prediction area are then considered during the computation with WinProp-IRT (or WinProp-UDP).

A progress bar shows how far the prediction is advanced. The computation can be cancelled at any time by clicking the Cancel button.
