ABSTRACT:
A wireless communication apparatus includes a transmitter to transmit a response request signal, a receiver to receives a response transmitted from a wireless communication medium in response to the response request signal, a level detector to detect a response receiving signal level, a memory to store threshold signal level of receiving signal of each type of medium; and a controller to set up a threshold signal level enabling the data writing to a medium to which a response is transmitted based on medium type data included in a response and a threshold signal level of a receiving signal of each type of stored medium, and starts the data writing to a medium to which a response is transmitted when a response receiving signal level is above the threshold signal level.
