The next generation RFID system for ubiquitous identification and sensing requires both energy and system efficiency. This paper describes an efficient passive RFID system using impulse ultra-wideband radio (IR-UWB), at a 10 m operation range. Unlike conventional passive RFID systems which rely on backscatter and narrowband radio, IR-UWB is introduced as the uplink (communication from a tag to a reader). By utilizing a specialized communication protocol and a novel ALOHA-based anti-collision algorithm, such semi-UWB systems enable a high network throughput (2000 tag/sec) under the low power and low cost constraint. A low power tag design for proof of concept is finally presented.
