PROPAGATION ENVIRONMENT DETECTION TECHNIQUE

摘要

PPROBLEM TO BE SOLVED: To provide a propagation environment detecting method for detecting a factor disabling information communication when the information communication can not be performed by radio communication equipment. PSOLUTION: A detection part 20 of a detecting device 10 receives and detects a radio wave of a predetermined frequency that the radio communication equipment uses for the information communication. An extraction part 30 extracts a pattern of a time-series variation in the presence and absence of the detected radio wave. An identification part 40 collates the extracted pattern with patterns that a plurality of devices superpose on a plurality of radio waves to identify the propagation environment of the radio wave that the radio communication equipment sends. A display part 50 displays the identification result. PCOPYRIGHT: (C)2004,JPO
