Abstract:
1. A radio apparatus for communicating with another radio apparatus, the radio apparatus comprising: a communication unit configured to select either one of a base station mode and a terminal mode so as to perform a communication using packet signals, the base station mode being such that a packet signal containing data indicating that an initial source and a final destination are not said own radio apparatus is to be communicated, and the terminal mode being such that a packet signal containing data indicating that the initial source or the final destination is said own radio apparatus is to be communicated; and a control unit configured to start said radio apparatus by setting said communication unit to the terminal mode, the control unit including: a detector configured to detect that the packet signal, which is sent from the another radio apparatus and which contains broadcast information, has been received via said communication unit before the predetermined duration of time has elapsed; a maintenance unit configured to maintain the setting of the terminal mode for said communication unit when the source of the packet signal detected by the detector is a radio apparatus compatible with the base station mode and the terminal mode; and a switching unit configured to switch the mode of said communication unit to the base station mode when the source of the packet signal detected by the detector is a radio apparatus compatible with the base station mode only, wherein when said control unit does not receive a packet signal, which is sent from the another radio apparatus and which contains broadcast information, via said communication unit before a predetermined duration of time has elapsed after the start of said radio apparatus, said control unit switches the mode of said communication unit to the base station mode.
