The first objective of this project is to develop and demonstrate complete single-chip passive UHF RFID readers and tags by integrating all the enabling technologies developed in the foundation ITF project under the Guangdong - Hong Kong Technology Cooperation Funding Scheme (GHS/086/04). The second objective is to further develop enabling technologies for the next generation of RFID tags and readers with advanced features according to the Electronic Product Codes (EPC) Generation 2 (G2) standards. For the RFID tags, focus will be on lower cost, smaller chip area, higher efficiency and thus longer communication distance, higher data rate, insensitivity to backing materials, rewritable memory, and embedded temperature sensor. For the RFID readers, both the transceiver and the baseband will be fully integrated for a system-on-chip for low power and small chip area and low cost, meanwhile, short-distance wireless capacity (Bluetooth and WLAN) will also be included.
