Title:
ULTRA WIDEBAND RADIO FREQUENCY IDENTIFICATION TECHNIQUES
Document Type and Number:
WIPO Patent Application WO2006070237
Kind Code:
A3
Abstract:
Ultra wideband (UWB) techniques are applied to radio frequency identification (RFID). For instance, a reader generates a UWB IR interrogation signal, and receives a UWB IR reply signal from an RFID tag in response to the interrogation signal. In addition, the reader may generate from the UWB IR reply signal a baseband response sequence. This sequence includes at least a tag identifier. A reader may store at least a tag identifier. Upon receipt of a UWB IR interrogation signal, the tag obtains a plurality of clock pulses from the UWB IR interrogation signal. Based on the plurality of clock pulses, the reader transmits at least the tag identifier in a UWB IR response signal.
