Broadband NFC - A system analysis for the uplink

Near field communication (NFC) is a new, short-range wireless connectivity technology that evolved from a combination of existing contactless identification and interconnection technologies. Products with built-in NFC will have the aim to simplify the way consumer devices interact with one another. Data-intensive applications based on NFC or applications for health care/e-government need an increase from the actual defined and standardised transmission rates of 424 kbit/s to a higher rate. The topic of this paper is to point out physical layer parameters, limitations and concepts, allowing to enhance the transmission rate of the 13.56 MHz NFC-systems. Finally one implementation of a lab scaled prototype with a transmission rate of 6.78 Mbit/s from card to reader is demonstrated and discussed.
