TERMINAL EQUIPMENT FOR A WARD, TERMINAL EQUIPMENT FOR A GUADIAN AND WIRELESS SYSTEM FOR PREVENTING A CHILD FROM GOING MISSING BY USING THE SAME

PURPOSE: A ward terminal device, a guardian terminal device, and a wireless missing children preventing system using the same are provided to confirm locations of children in a remote place by displaying location information of ward terminal devices of children on a web page. CONSTITUTION: An RSSI(Received Signal Strength Indicator) measuring unit(120) measures an RSSI of an adjacent ward terminal device for performing a wireless communication process. A memory(130) stores a data packet transmitted from the adjacent ward terminal device for performing the wireless communication process. The memory stores the measured electric field strength. A data packet generation unit(140) generates a transmitting data packet by using the data packet and the measured electric field strength. A control unit(170) controls an RF communication module in order to transmit the transmitting data packet to another adjacent ward terminal device.
