1. A display device comprising:
a communicator comprising communication circuitry configured to receive a wireless signal transmitted by a wireless router; and
at least one processor, individually and/or collectively configured to:
retrieve multipath channel characteristic data based on the wireless signal,
generate similarity data representing a similarity for each time period of the multipath channel characteristic data,
adjust a threshold based on the similarity data by decreasing the threshold based on the similarity data in case an environmental indicator that indicates a presence of a user has not appeared, and increasing the threshold based on the similarity data in case the environmental indicator has appeared,
measure a motion within a specified range of the display device based on a comparison result between the similarity data and the threshold, and
control the display device based on the motion within a specified range of the display device.
