<p>In a detector device 10 of the invention, a wave detection module 20 receives and detects radio waves in a predetermined frequency band, which is used by a target wireless communication device for telecommunication. An extraction module 30 extracts a pattern representing a time-series variation in the presence or absence of the detected radio waves. An identification module 40 compares the extracted pattern with inherent patterns of radio wave transmitted from plural devices, which use radio waves in the predetermined frequency band and include the target wireless communication device, and thereby identifies the propagation environment of the radio waves transmitted from the target wireless communication device. A display module 50 displays a result of the identification by changing lighting statuses of LEDs. When smooth telecommunication of the wireless communication device is interrupted, the invention thereby identifies the reason for the interrupted communication.</p> |
