Abstract
A wireless communication apparatus capable of preventing data leakage in wireless communication. A transmitted data frame receiver receives a transmitted data frame which is transmitted from a terminal to the wireless communication apparatus. An address information converter converts the address information of the terminal included in the transmitted data frame, into the address information of the own wireless communication apparatus. A radio transmitter transmits the transmitted data frame by radio. An address information comparator compares the address information included in a received data frame received by a radio receiver, with the address information of wireless communication apparatuses being stored in an address information memory. A received data frame destruction unit destructs the received data frame depending on the comparison result.
