A novel design of planar tag antenna with broadband operation for RFID system is proposed. With the use of two parasitic strips inset along the closed loop of the input IC chip in this proposed tag antenna, a new resonant mode close to the first operating mode of the regular dipole antenna is excited to enhance the operating bandwidth. And, the obtained impedance bandwidth across the operating band...
RFID middleware, a bridge between RFID hardware and enterprise application systems, enables enterprise to reap the full benefits of RFID technology. Current RFID middleware is inflexible and monolithic and fails to address the emerging needs for adaptation to changing requirements. In this paper, we put forward a component-based, service-oriented RFID middleware architecture that provides developers...
Mobile RFID systems are increasingly being deployed in industry and m-commerce. Due to the inherent limitations of mobile devices (PDAs, mobile phones, etc.) such as CPU speed, memory and storage capacity, special supports must be provided to utilize RFID in mobile devices. However, currently, most of organizations put their focuses on RFID middleware running on desktops or servers, while few attentions...
RFID reader networks generate an abundance of event data every day. Those data are raw streams of RFID data, and do not bear any business meaning. A challenge issue in RFID middleware is the design of an appropriate mechanism for dealing with the mass data so that logical conclusions and state of the business can be derived. The paper investigates the issues related to effective RFID data management...
The advanced deployment of wireless networks and the increasing popularity of mobile devices, in conjunction with RFID technology, are going to enhance our life style. There are some limitations exist in traditional exhibition environment: (1) mobile guide only acts as a multimedia information query device, and visitors can not get customized services to make their tours more interesting and convenient;...
Radio frequency identification (RFID) is expected to be widely used in the future, as it can be embedded into everyday items as RFID tags. Using RFID technology, enterprises can share real-time data about products with trade partners over the Internet. Application service provider (ASP) provides services for clients in a central managing way by Internet. Users who subscribe the ASP service do not...
