Abstract
A wireless LAN device for wirelessly communicating using a specific frequency channel shared by a radar and a wireless LAN system. The wireless LAN device includes a plurality of antennas; a wireless communication unit including a plurality of transceiver circuits respectively provided for each of the plurality of antennas; and a controller that controls the wireless communication unit. The wireless communication unit wirelessly communicates in accordance with a multiple input multiple output (MIMO) scheme by the plurality of transceiver circuits, and the controller controls the wireless communication unit to execute radar wave monitoring on a frequency channel different from a frequency channel in use for wireless communication using one of the plurality of transceiver circuits when the frequency channel in use for the wireless communication is the specific frequency channel.
