Chapter 1: Difference Plot Add-in

1 Difference Plot Add-in

1.1 IntroductionThe Difference Plot add-in is developed by Forsk, and is available on demand. It can be used with Atoll version 2.4.1 Build1632 and above. The Difference Plot add-in can be used to generate coverage plots which show the difference of signallevels between two selected signal-level based coverage prediction studies. You can use this add-in to precisely evaluatethe differences between two network scenarios.

The Difference Plot add-in can generate three types of difference plots:

• Coverage map of areas covered by scenario A but not by scenario B• Coverage map of areas covered by scenario B but not by scenario A• Coverage map of areas covered by both scenarios

1.2 Installing the Difference Plot Add-in

1.2.1 Installing the Add-inTo install the add-in:

1. Double-click the setup icon to run the setup program.2. Specify an installation folder for the add-in.

It is not necessary to install the add-in in the Atoll installation directory.

3. Specify whether the installation should only be performed in the current user profile or for all users.

4. Click Next to start the installation.

5. Click Close to exit the setup program when the installation is finished.

1.2.2 Repairing the Already-Installed Add-inThe setup program allows you to repair the already-installed add-in by re-installing it using the installation parameters thatyou defined when performing the installation. To repair an installation:

1. Double-click the setup file icon to start the setup program.2. Choose Repair Difference Plot Tool.3. Click Finish to repair the installation.

1.2.3 Uninstalling the Add-inTo uninstall the Difference Plot add-in:

1. Double-click the setup file icon to start the setup program.2. Choose Remove Difference Plot Tool.3. Click Finish to uninstall the add-in.

1.2.4 Managing the Add-in in AtollOnce installed, the add-in will be available in the list of add-ins installed with Atoll. You can access the Add-ins and Macrosdialog in Atoll through the Tools menu in the menubar.

You can activate or deactivate add-ins in this dialog to set their availability in Atoll. For example, if you uncheck the DiffPlots

Class check box in this dialog, the command Difference Plots will not be available in the Tools menu, and the icon willnot be available in the Toolbar.

Note:

• You can also uninstall the add-in through Windows Control Panel > Add or Remove Programs.

To make the add-in available:

1. Select Add-ins and Macros from the Tools menu in the menubar.2. Check the DiffPlots Class check box in the Add-ins and Macros dialog.3. Click Close to exit the dialog.

The icon and the Difference Plots command will now be available in the Toolbar and in the Tools menu respectively.

You can also verify the version and installation details about the add-in by clicking the Infos... button in the Add-ins andMacros dialog:

1.3 Using the Difference Plot Add-in

1.3.1 Generating Difference PlotsYou require two signal-level based coverage prediction studies to run the Difference Plot add-in. Both the coverageprediction studies should have a coverage plot gradient of 1 dB. You can choose other parameters of the coverageprediction studies as you like, but you must keep all the parameters same for both the coverage prediction studies in orderto get meaningful comparison results.

Let us suppose that you have created two coverage scenarios, Scenario A and Scenario B, with the following displayparameters.

Figure 1.8: Add-ins and Macros Dialog in Atoll

Figure 1.9: Add-in Details

Note:

• You can create a signal-level based coverage prediction study with 1 dB display gradient and thenduplicate it in order to have the exact same parameters for the other coverage prediction study as well.

Before running the Difference Plots add-in, make sure that both of the coverage prediction studies are locked.

To generate difference plots:

1. Click the Difference Plot icon in the Toolbar to open the Difference Plot add-in dialog.

2. Specify the coverage prediction studies to be used by the add-in.

The add-in subtracts the signal levels of the first coverage prediction study from the signal levels of the second coverageprediction study.

The coverage prediction lists contain the coverage predictions of all the documents currently open in the Atoll session. Youcan compare coverage predictions from different documents. When several documents are open, the names of thecoverage predictions available in the lists include the name of the document they belong to, as a prefix.

3. Specify if you want to see areas where the difference is zero.

When the checkbox "Use blank color on areas covered by both studies where the difference is zero" is unchecked, areaswhere the difference is zero is displayed in red color.

4. Click OK to generate difference plots.

The time required to generate the difference plots depends on the size of the coverage prediction studies being compared.

1.3.2 ExampleThis example shows two coverage prediction studies, Scenario A and Scenario B, and their difference plots.

1.3.3 LimitationsPlease keep the following points in mind when using the Difference Plot add-in:

• The coverage prediction studies must be calculated and up to date before running the Difference Plot add-in.• If you have changed the display settings of your coverage prediction studies, you must update the coverage

studies before running the Difference Plot add-in. You have to calculate the coverage prediction studies afterchanging the display settings in order to update them.

Note:

• You can create a signal-level based coverage prediction study with 1 dB display gradient and thenduplicate it in order to have the exact same parameters for the other coverage prediction study as well.
