Claim 2:
3. A display device comprising:
a communicator comprising communication circuitry configured to receive a wireless signal transmitted by a wireless router;
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 the wireless signal,
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 the display device, based on a change in the representative values over time, and
control the display device based on the determined motion within the specified region of the display device,
wherein a number of subcarriers of the result data is less than a number of subcarriers of the multipath channel characteristic data before the preprocessing.
