2a. Zusammenfassung

Die Planung von digitalen Mobilfunknetzen (GSM, Global System for Mobil communication) erfordert umfangreiche Visualisierungs- und Interaktionstechniken. In diesem Artikel wird eine Darstellungskomponente vorgestellt, die speziell zur Planung und Präsentation eines digitalen Mobilfunknetzes dient. Hierbei erlaubt die hybride Darstellung des Systems die Kombination aller für die Funknetzplanung benötigter Datensätze. Durch die Interaktion mit der Darstellungskomponente wird es dem Anwender ermöglicht, die Daten zu dem Mobilfunknetz zu modifizieren und Szenarien für die Simulation zu erstellen. Durch eine graphisch-interaktive Benutzungsoberfläche erhält der Anwender einen intuitiven Zugang zum System. Die Konzepte, die in diesem Artikel vorgestellt werden, bildeten die Basis für die Entwicklung dieses raumbezogenen Informationssystems zur Planung digitaler Mobilfunknetze. Die Darstellungskomponente befindet sich täglich in allen D1-Planungsstellen der DeTeMobil zur Planung und Präsentation des D1- Mobilfunknetzes im Einsatz.

2b. Abstract

Planning a digital, cellular radio network (GSM, Global System for Mobile communication) requires powerful visualization and interaction techniques. In this paper we present a visualization component with special emphasis on flexible, yet exact, hybrid display of data and on a close interaction between planner, visualization system, and simulation process. The concepts outlined in this paper have been the basis for implementing a specialized geographic information system for planning cellular radio networks. This system is being used by a major German telecommunications company and has proven its usefulness in everyday work.
