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.
