LOCATION DETERMINATION METHOD FOR PLACING SENSOR USING WIRELESS COMMUNICATION IN BUILDING AND LOCATION DETERMINATION SYSTEM FOR PLACING SENSOR USING WIRELESS COMMUNICATION IN BUILDING

摘要

A location determination method (200) for arranging sensors based on wireless communication in a building. The method includes: a step in which a first measuring device transmits a first test packet, which is digitally modulated to a specific channel, from a first location in the building (210); a step in which a second measuring device receives the first test packet, and transmits a first echo-back signal through the specific channel from a second location in the building (220); a step in which the first measuring device receives the echo-back signal transmitted from the second measuring device, and measures first channel quality of the specific channel based on a feedback signal (230); a step in which the first measuring device (240) transmits a second test packet digitally modulated to the specific channel (240); a step in which the second measuring device receives the second test packet and transmits a second echo-back signal through the specific signal (250); and a step in which the first measuring device receives the echo-back signal transmitted from the second measuring device, and measures second channel quality of the specific channel based on the feedback signal.
