Abstract
Reliability of wireless communication is the key to the next stages of the imminent industrial evolution known as Industry 4.0. Removing the bonds of cabling and wires will provide the ability of free movement and the possibility of deployment in previously unreachable locations. To build confidence in the reliability of wireless transmission systems, a method for measuring said reliability is required. This article describes such a method which forms the basis of two interlinked testbeds being developed within the scope of the Celtic Plus project ReICOvAir.
Zusammenfassung
Zuverlässigkeit von Funksystemen ist der Schlüssel, der die Tür zur nächsten Stufe der Entwicklung von Industrie 4.0 öffnen wird. Hierdurch können die Beschränkungen des kabelgebundenen Zeitalters endgültig überwunden, ungeahnte Flexibilität geschaffen und neue Anwendungsorte erschlossen werden. Um Vertrauen in die Zuverlässigkeit von Funksystemen zu erzeugen, ist eine Methode notwendig, diese Zuverlässigkeit zu messen.
Dieser Artikel beschreibt eine solche Methode, angefangen von den Anforderungen an ein solches Messsystem bis hin zu zwei verbundenen Testständen, die innerhalb des Celtic Plus Projekts ReICOvAir entwickelt werden.
