• OpenFone
  In diesem Projekt wurden Demonstratoren für die Implementierung von Mobilfunk-Systemen mit Hilfe von Open-Scource Komponenten erstellt. Dabei wurden nicht nur verschiedene Komponenten eines Mobilfunknetzes mit freier Software implementiert werden, sondern diese Komponenten auch genutzt, um die damit möglichen Angriffe auf bestehende Mobilfunknetze und Mobiltelefone zu untersuchen.
