1. A mobile terminal, comprising:
a communication unit that is paired with a display device and configured to perform a communication;
an input unit configured to receive a search command from a user;
a processor configured to:
transmit a search function activation command to the display device through the communication unit,
receive a packet signal from a remote control device that transmits a packet signal at a predetermined packet period according to the search function activation command of the display device,
obtain a signal strength of the packet signal,
receive packet pattern information from the display device, and
determine a distance with the remote control device based on whether the packet is changed and the signal strength,
wherein the processor requests the display device to reset the predetermined packet period if it is impossible to determine whether the distance to the remote control device is getting closer or farther within a predetermined time, and
wherein the processor requests the display device to reset the packet period longer when a noise packet signal is generated more than a predetermined reference value for the predetermined time.
