Radio communication apparatus and radio communication method

A radio communication apparatus for performing the authentication processing with another apparatus via radio communication, comprising:

• a radio communication antenna;
• a communication circuit;
• a switch for switching over connection and disconnection between said radio communication antenna and said communication circuit;
• and
• control means for detecting the disconnection between said radio communication antenna and said communication circuit by said switch, and performing the authentication processing in connection with this disconnection.

A radio communication apparatus for performing the authentication processing with another apparatus via radio communication, comprising:

• a radio communication antenna;
• a communication circuit;
• a switch for switching over connection and disconnection between said radio communication antenna and said communication circuit;
• detection means for detection connection or disconnection state between said radio communication antenna and said communication circuit by said switch at a predetermined timing;
• and
• control means for performing the authentication processing upon the detection by said detection means of disconnection between said radio communication antenna and said communication circuit by said switch.

A radio communication apparatus for performing the authentication processing with another apparatus via radio communication, comprising:

• a switch for designating to perform the authentication processing;
• output control means for lowering the radio communication output level to a predetermined value in connection with the operation of said switch;
• and
• control means for performing the authentication processing, after the output level is lowered by said output control means.

A radio communication method for establishing a network by performing the authentication processing with another apparatus via radio communication, comprising steps of:

• receiving a command of authentication processing execution;
• lowering the radio communication output level to a predetermined value in connection with this reception;
• and
• thereafter, starting the authentication processing for establishing the network with another apparatus.
