CEA-Leti and Nokia Research have developed a RFID wireless interface which can transmit data at 112Mbit/s between a mobile phone and memory tag.
The radio-frequency identification (RFID) system incorporates impulse Ultra-Wide Band (UWB) for data transfer.
It also uses narrow-band Ultra high frequency (UHF) signal, used for synchronisation and remote powering.
The researchers have demonstrated an RF circuit which will manage physical layer communication at both ends of the communication link, i.e. the same front-end can be used either in the memory tag or in the reader.
The device is powered from the narrow-band signal and provide power for an external non-volatile memory device.
