Abstract: Disclosed is a wireless communications device with strong realtime performance, giving rise to no latency in communications even if communications errors arise in the communication frame MAC header. MAC header information is used to determine whether or not the destination address of a received data frame is the address of a concerned wireless communications device (1). MAC header information allocated among a plurality of MAC headers is employed in selecting MAC header information without errors. If all MAC header information is in error, a majority determination processing unit (13) is used to effect a majority determination of the MAC header information and generate correct MAC header information. A received data extraction unit (14) removes the received frame header, etc., extracts the received data, and outputs same to an external device.
