    Abstract: An RFID reader, RFID tag, and method thereof for performing a write check of tag data. According to an exemplary embodiment, the RFID reader may include: a transmitter to transmit a write check command to an RFID tag; a receiver to receive a response including a check value of data, which needs a write check, from an RFID tag that has received the write check command; and a controller to perform information transmission and reception processes, and check data written on the RFID tag by using the received response.

    Abstract: Disclosed are a method and apparatus for connecting a terminal and a base station in a multi-hop network. A method of a terminal may comprise: receiving cell selection and reselection criteria information broadcast from a base station; determining candidate base stations among all base stations capable of communicating with the terminal based on the cell selection and reselection criteria information; selecting one connection scheme from a lightening backhaul load (LBL) scheme or a maximum reference signal received power (RSRP) scheme based on a tolerable gap, which is a parameter for determining the candidate base station; selecting one candidate base station from among the candidate base stations as a target base station based on the one connection scheme; and connecting to the target base station.

    Abstract: Disclosed are a high speed wide range RFID tag capable of improving a data transmission speed and a recognition distance between an RFID tag and an RFID reader by controlling a reflected power as multi levels through adjustment of a reflection coefficient in the RFID tag, and a method of controlling the same. The RFID tag includes a data converting unit configured to convert stored RFID serial tag data into a number of multi-level parallel data according to a request of an RFID reader, a reflection coefficient adjusting unit configured to generate a plurality of reflection coefficients corresponding to a number of the converted parallel data, and a transmitting unit configured to transmit a number of the multi-level parallel data according to the generated plurality of tag reflection coefficients through an antenna to the RFID reader.

    Abstract: A digital twin federation system for interoperability and federation between digital twins and an operating method thereof are provided. The digital twin federation system includes single digital twins to be federated, a metadata repository that stores metadata on the single digital twins and a federated digital twin, a federated digital twin generated by federating the single digital twins, and a management device that searches for a single digital twin providing a specific service among the single digital twins from the metadata repository through a search function to determine the single digital twin to be a digital twin for the federated digital twin, generates the federated digital twin where the single digital twins are federated, and generates a tool for providing a service of the federated digital twin, thereby expanding existing services and provide new services by federating digital twins, and easily solving problems involving domains through simulation and visualization.
