Bei der Backscatter Communication nutzen die batterielosen Ger\u00e4te externe Funksignale, reflektieren und modifizieren diese, um mit dem Echo dann eigene Informationen zu transportieren. Skizze: Sora AI\r\n<\/span><\/div>
\n <\/p>\n

Das Internet der Dinge (IoT) produziert immer mehr Ger\u00e4te, die regelm\u00e4\u00dfig ihre Batterien erneuern m\u00fcssen. Eine internationale Forschergruppe, darunter die Technische Universit\u00e4t Graz, will diese Problematik l\u00f6sen, indem sie IoT-Ger\u00e4ten Strom per drahtlose \u00dcbertragung oder aus Umgebungslastquellen bereitstellt. Das EU-gef\u00f6rderte Projekt „Ambient-6G“ erhielt 8,4 Millionen Euro.<\/h2>\n

Die Zahl der Internet-of-Things-(IoT)-Ger\u00e4te wird sich in den kommenden Jahren rapide vervielfachen. Ein wichtiger Aspekt hierbei ist die Reduzierung von Abf\u00e4llen und die Vermeidung von Batterie-Ersatz und -entsorgung. Das Ambient-6G-Projekt konzentriert sich auf die Erneuerung des Internets der Dinge, indem es Ger\u00e4te per Funk oder durch Energie-Aufkommens (W\u00e4rme, Vibrationen) aus dem Umfeld<\/strong> betreibt.<\/p>\n

Energie-neutrales R\u00fcckstrahl-Kommunikation<\/h3>\n

Die Forscher arbeiten an einer neuen Kommunikationsmethode f\u00fcr IoT-Ger\u00e4te: die „backscatter communication<\/strong>„. Diese passive Kommunikation \u00fcbertr\u00e4gt Informationen, indem die Ger\u00e4te sehr leicht modulierte Funksignale reflektieren. Dies erm\u00f6glicht es, dass die kleinen Energien, die von den Funksignalen generiert werden, genug sind, um die Ger\u00e4te zu betreiben. Backscatter-Communication funktioniert wie ein „Klang-Echo“, bei dem eine Sendestelle einen Funksignal aussendet und das Empfangsger\u00e4t das Signal reflektiert, um seine eigenen Informationen zu \u00fcbermitteln.<\/p>\n

Verteilte Antennensysteme erm\u00f6glichen niedrigen \u00dcbertragungspotenz<\/h3>\n

Das Ambient-6G-Projekt untersucht auch Verteilte Antennensysteme als effektive Kommunikationsmethode mit IoT-Ger\u00e4ten<\/strong>. Diese Systeme erlauben es, den \u00dcbertragungspotenz der einzelnen Antennen niedrig zu halten und so sch\u00e4dliche Strahlung aus dem Umfeld zu vermeiden.<\/p>\n

Anwendungsgebiete<\/h3>\n

Batteriefreie IoT-Ger\u00e4te haben ein breites Spektrum an Anwendungsbereichen. Zum Beispiel k\u00f6nnten elektronische Etiketten in gro\u00dfen Superm\u00e4rkten helfen, Abf\u00e4lle zu reduzieren und maintenance-Kosten zu senken. In der Logistik k\u00f6nnten G\u00fcter ohne Batterien \u00fcber lange Strecken und mit hoher Genauigkeit lokalisiert werden.<\/p>\n

Schwache Signale stellen ein Hindernis dar<\/h3>\n

Es gibt noch einige Herausforderungen, die vorab zu \u00fcberwinden sind, bevor batteriefreie IoT-Ger\u00e4te eine praktische Option werden. Dazu geh\u00f6ren auch Signalverarbeitungsmethoden. Die Forscher m\u00fcssen spezielle Algorithmen entwickeln, um n\u00fctzliche Informationen aus den rauschenden Signalen zu extrahieren.<\/p>\n
