A radio communication apparatus capable of executing communication and processing of audio data and image data by simplifying the system structure where various apparatuses are connected via a terminal adapter (TA), which conventionally used a large area and whose connection was complicated. More specifically, the system structure comprises: an interface unit (RS232C controller , driver , PIAFS controller , I.460 processor ) connected with a data terminal (PC) by radio or by cable; radio communication unit (PHS engine unit ) for realizing radio communication with a wireless telephone unit; and transmission arrangement (first port switch , second port switch , ISDN interface unit and the like) for transmitting at least one of the data transmitted by the data terminal (PC) or the audio data transmitted by the wireless telephone unit, to the digital public communication line (ISDN).
