PROBLEM TO BE SOLVED: To provide a radio communication apparatus which ensures characteristics against higher sound quality, interruption and disturbance as a cordless phone system unique to a company while ensuring the connection of sound communication/data communication in a Bluetooth (BT). SOLUTION: A base unit decides whether or not company identifying information transmitted from a cordless handset is specific information in connecting a line in a Bluetooth (BT) communication mode, performs communication in another radio communication standard (company's own mode) on determining that the company identifying information is the specific information, and performs the communication in a BT standard on determining that the company identifying information is not the specific information. The communication apparatus allows long-distance communication at higher sound quality with the other apparatus capable of performing cordless communication in the company's own mode using an error handling function, and sound communication at a usual sound quality in a BT data format allowing short-distance communication even when the company identifying information is not the specific information.
