摘要
In a detector device 10 of the invention, a wave detection module 20 receives and detects radio wave 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 presence or absence of the detected radio wave. An identification module 40 compares the extracted pattern with inherent patterns of radio wave transmitted from plural devices, which use the radio wave in the predetermined frequency band and include the target wireless communication device, and thereby identifies the propagation environment of the radio wave 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 a wireless communication device is interrupted, this arrangement of the invention desirably identifies the reason of the interrupted communication.
