Abstract: Data communicated on one wireless channel is converted and communicated via a wired line. Alternatively, data communicated on a plurality of wireless channels is bundled and communicated via a wired line using a number of channels smaller than that of the wireless channels. In a case where another wireless communication apparatus wishes to use a wireless communication channel when a plurality of wireless channels are being used for communication, some of the plurality of wireless channels are released, thereby making it possible for the other communication apparatus to perform communication even when communication is being carried out using the plurality of wireless channels. When communication by the other wireless communication apparatus subsequently ends, communication on the original number of wireless channels is resumed.

Abstract: 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 219, driver 220, PIAFS controller 228, I.460 processor 236) connected with a data terminal (PC) by radio or by cable; radio communication unit (PHS engine unit 237) for realizing radio communication with a wireless telephone unit; and transmission arrangement (first port switch 229, second port switch 233, ISDN interface unit 225 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).
