Summary

Data-intensive applications based on NFC (Near Field Communication) or applications for healthcare/e-government will need an increase of the actual defined and standardized transmission rates of 848 kbit/s. It is topic of this work to point out physical layer parameters, limitations and concepts, allowing to enhance the transmission rate of passive 13.56 MHz RFID systems. Additionally, ongoing standardization activities at ISO 14443 are pointed out, having the aim to standardize significantly enhanced datarates. Finally, an implementation of a lab-scaled prototype with a transmission rate of 6.78 Mbit/s is demonstrated and discussed.

Zusammenfassung

Datenintensive Anwendungen wie NFC (Nahfeld-Kommunikation) oder Applikationen im Gesundheitsbereich und im Bereich des E-Government erfordern es, die aktuell standardisierte Datenrate von 848 kbit/s zu erhöhen und zu erweitern. Es ist Gegenstand der aktuellen Untersuchungen, physikalische Parameter, Limitierungen und mögliche Konzepte aufzuzeigen, die es erlauben, die aktuellen gültigen Datenraten von 13,56 MHz bei RFID-Systemen zu erhöhen. Im Speziellen werden aktuelle Standardisierungsaktivitäten in Richtung höherer Datenraten im Rahmen von ISO 14443 diskutiert. Abschließend wird ein diskreter Prototyp vorgestellt, der eine Übertragungsrate von 6,7 Mbit/s erreicht.
