Abstract:
A tag apparatus communicating with a reader acquires a command from a signal that is received from the reader, converts data corresponding to the acquired command to a plurality of multi-level parallel data, and generates a plurality of tag load impedances based on bias voltages that are mapped to correspond to each level of the plurality of parallel data. Therefore, a signal having electrical energy corresponding to the plurality of tag load impedances is transmitted to the reader.
Abstract:
A wireless communication method using a control channel between wireless communication devices including: exchanging profile information between a node and intermediate relay nodes therearound so as to allow the node to transmit/receive data to/from a destination node; determining, by the node, a first intermediate relay node using the profile information and determining a wireless communication mode with the first intermediate relay node; and transmitting/receiving data between the node and the first intermediate relay node by the determined wireless communication mode is provided.
Abstract:
A tag of an apparatus for simultaneously identifying massive tags according to the present invention may include an analog circuit unit to communicate with a reader through an analog signal and to receive energy via magnetic coupling with the reader. Further, the tag may include a digital circuit unit to be supplied with power from the analog circuit unit. The digital circuit unit may support a sleep mode for the tag to stand by in a low power state after transmitting an identifier (ID) to the reader and a wait mode for controlling random access to the reader.
