PROBLEM TO BE SOLVED: To provide a wireless communication system which allows for reduction of allophone to a level not causing any practical problem even if a packet, where the data signal for data communication is inserted into a voice frame, is received by an existing wireless machine not corresponding to a mode for transmitting only the data for data communication.SOLUTION: When operating a wireless communication system in a mode for transmitting the data for data communication in place of a digital audio signal, the transmission unit of a wireless machine generates a packet where the data for data communication is inserted into the position of the voice frame excepting an arbitrary position and the data frame, and specific data is inserted into an arbitrary position of the voice frame. As the specific data, the data having high possibility of generating an error, when the data inserted into the voice frame is decoded using an audio codec, is used.SELECTED DRAWING: Figure 4 |
