explains the entire process from the import of network data in Atoll to the production of prediction studies. The purpose of this document is to give an overall understanding for radio engineers, who never use Atoll. This document does not explain the algorithm and don’t give detailed explanation. The user may find in the “Technical Reference Guide” and “User Manual” the concrete algorithm and the detailed explanation of parameters. The user may find all projects and map data in the CD, which was provided with this document. This document describes how to get started using the Atoll version 3.1.0.     Atoll Getting Started-GSM Version 3.1.0   © Forsk 2011 4/216 2 Installation The installation of Atoll is simple and needs an administrator profile. 1 、  The naming structure of the Atoll installation file is generally: version number.language.build number.exe, as shown bellow. 2 、  Install Atoll by double clicking on the installation file. 3 、  In the appeared dialog box, click on the “next” button and choose the installation directory (the default path is C:\Program File\Forsk\Atoll). The minimum requirement for the installation of  Atoll is a disk space of 111.9 MB.
