Abstract:
PURPOSE: A location and state management device is provided to monitor the state and location of a material by minimizing the function of a machine to machine communication device attached to the material. CONSTITUTION: A control server(130) manages the state and location of a material based on the importance of the information material and the auxiliary information. A transmitter senses the additional information of the area in which the material is located. Machine to machine communication devices(120a-120d) are attached to the material. Each of the machine to machine communication device senses the importance information of the object. Each of the M2M communication devices receives additional information from the transmitter. Each of the M2M communication devices transmits the additional information and the importance information to the control server.

Abstract:
PURPOSE: An RFID security reader is provided to operate a security engine at high speed by integrating a security engine to a modem of an RFID security reader. CONSTITUTION: A processor module(110) processes a security protocol and configures transmission data to an RFID(Radio Frequency ID) security tag. An encoding module(1221) encodes the transmission data. A decoding module(1222) decodes reception data which is received from the RFID security tag. A modem(120) processes the encoded data and processes the reception data.
Abstract:
PURPOSE: An RFID tag capable of supporting a normal mode and a security mode, interrogator, and operation method thereof are provided to offer various application services by supporting the function of a RFID tag and a security. CONSTITUTION: An operation mode determination unit(1200) determines a current operation mode. An operation state transition unit(1220) moves an operation state based on the current operation mode. When the current operation mode is determined to a security mode, the operation mode determination unit transmits PC(Protocol Control) information, a XPC_W2 parameter, a XPC_W1 parameter, and tag identification information to an interrogator. The operation mode determination unit includes a security channel forming unit.
Abstract:
PURPOSE: A location tracking apparatus, and a method and an apparatus for a location tracking service using the same are provided to track a location of a tag even though only one tag is recognized. CONSTITUTION: A GPS receiving unit(300) receives a GPS signal from a GPS satellite to generate self location information. A memory(310) stores unique ID information. A processor unit(320) generates the first transmission message frame using the self location information and unique ID information and generates the second transmission message frame using only the unique ID information.

Abstract:
A method for allocating bandwidth of PON(passive optical network) assigning band according to the bandwidth allocation standards is provided to assign the bandwidth of upward optical network terminal by determining the upper bandwidth of the optical network. Wavelength is divided and wavelength is set up as the respective different wavelength. Each wavelength downstream wavelength time is set up. Data of a packet unit uses wavelength. The data is transmitted to the optical network terminals of the first downstream wavelength. The wave length is changed in the first downstream wavelength time out. The data is transmitted according to the changed wavelength.
Abstract:
A link module of an ONT/ONU with an optical wavelength aligning function in WDM-PON, a link system, and a method of aligning optical wavelength are provided to perform communication by initializing the optical wavelength of the link module automatically without intervention of a user or an installer. An initial information creation unit(111) creates link initiation information which is logical information of a predetermined format for checking a transmission state. A wavelength control unit(113) assigns output wavelengths to be outputted from a wavelength group sequentially. An optical transmission unit(115) transmits an assigned optical signal including the link initiation information to the assigned wavelength, whenever assigning the output wavelength from the wavelength control unit. A wavelength selection unit(119) stops the sequential assignment to the wavelength control unit if a response optical signal including response initiation information is received.
Abstract:
An extendable loop-back type PON(Passive Optical Network) and a scheduler and scheduling method for the PON are provided to reduce a maintenance cost and an upgrading cost of a network by integrating advantages of TDM and WDM techniques. An OLT(Optical Line Terminal)(200) includes wavelength-variable optical transmitters(210) and wavelength-fixed optical transmitters(220). An RN(Remote Node)(250) includes optical combining/distributing units(270) that receive an optical signal transmitted from the wavelength-variable optical transmitters(210), distribute the received optical signal according to each wavelength, and transmit it to ONTs(Optical Network Terminals)(290). The ONTs(290) transmit uplink data to the OLT(200) by using the same wavelength as that of the optical signal received from the OLT(200).
