LOCATION BASED SERVICE SYSTEM AND METHOD BASED ON RSSI AND PLC USING RF AND PLC

摘要

PURPOSE: A location based service system and method based on RSSI(Received Signal Strength Indicator) and PLC(Power Line Communication) are provided to reduce resource waste and supplement an RF communication distance. ;CONSTITUTION: A movable node(100) performs an RF communication. A plurality of fixed nodes(200) RF-communicated with the movable node, calculates RSSI value from the movable node and performs PLC. A PLC server is connected to the fixed nodes with PLC and collects and monitors location data according to the RSSI value of the movable node.;COPYRIGHT KIPO 2011
