Claim 18:
19. A display device comprising:
a memory configured to store one or more instructions; and
a processor configured to execute the one or more instructions stored in the memory,
wherein the processor is configured to:
continuously retrieve multipath channel characteristic data based on a wireless signal transmitted by a wireless router,
perform preprocessing on the retrieved multipath channel characteristic data of the wireless signal,
determine representative values for each reference time by calculating a similarity for each time period of result data corresponding to a result of the preprocessing,
determine a motion within a specified region of a display device, based on a comparison result between the representative values and an adaptive threshold, and
control a power mode of the display device to be in a power saving mode based on the determined motion indicating no motion within the specified region of the display device.
