Title:
METHOD FOR DETECTING BROADBAND ILLEGAL WIRELESS SIGNAL
Document Type and Number:
WIPO Patent Application WO/2017/217683
Kind Code:
A1
Abstract:
The present invention comprises: a step in which a receiving unit receives surrounding wireless signals of a location from which an illegal wireless signal is to be detected; a step in which a detecting unit constructs a reference multispectral table and generates reference frequency information by generating a base resolution spectrum for extracting a signal of a predetermined frequency band from the received surrounding wireless signals at a base resolution and generating a multiple resolution spectrum for an extraction at a resolution of a positive integer multiple of the base resolution; a step in which the detecting unit constructs a detection multispectral table and generates detection frequency information by generating a base resolution spectrum for the extraction of a signal of a predetermined frequency band from the wireless signals detected from the location to be detected at the base resolution and generating a multiple resolution spectrum for extracting at a resolution of a positive integer multiple of the base resolution; and a step in which the detecting unit checks whether a signal intensity value larger than a signal strength value in the reference multispectral table exists in the detection multispectral table.
