  • Multiple input and multiple output communication apparatus and channel scanning method thereof
    Patent number: 10044416
    Abstract: A MIMO communication apparatus and a channel scanning method thereof that can reduce a channel scanning time are provided. The channel scanning method includes receiving an input request for channel scanning, and scanning for a plurality of channels simultaneously by independently using a plurality of antennas in accordance with the input request. The apparatus includes a control unit which designates channels for scanning; a frame generating unit which generates a search frame if the channel scanning is active scanning; and a transceiver unit which includes a plurality of antennas and which assigns the channels designated by the control unit to the plurality of antennas, transmits the search frame generated by the frame generating unit through the plurality of antennas, and receives a response frame to the transmitted search frame; wherein the transceiver unit assigns different channels to the plurality of antennas, respectively.
