Abstract
In a detector deviceof the invention, a wave detection modulereceives and detects radio wave in a predetermined frequency band, which is used by a target wireless communication device for telecommunication. An extraction moduleextracts a pattern representing a time-series variation in presence or absence of the detected radio wave. An identification modulecompares 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 moduledisplays 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.
