摘要： A data rate is to be determined depending on circumstances. A control unit (30) transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit (30) receives rate information from the targeted radio apparatus. The control unit (30) sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit (30) identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit (30) lowers the frequency at which the rate request signal is transmitted.

摘要： A packet communication unit (20) executes radio communications in such a manner as to be accessible to other terminal apparatuses that have already been communicating wirelessly with a base station apparatus. The signal processing unit (22) generates a connection request signal to be transmitted from the packet communication unit (20) to the base station apparatus by way of the other terminal apparatuses. The signal processing unit (22) processes a connection response signal received, from the base station apparatus, by the packet communication unit 20. Such a sequence of operations allows the signal processing unit (22) to perform connection processing between a terminal apparatus and the base station apparatus.

摘要： A setting unit defines the first frame and the second frame and selects use of the first frame or the second frame. A generation unit generates control information which is defined by the same format regardless of the selection by the setting unit and which includes at least information related to the base station broadcast period. The generation unit puts information related to the ratio between the priority period and the general period into the control information and reflects the selection by the setting unit to the ratio. The modem unit and the RF unit broadcast a packet signal including the control information in the base station broadcast period.

摘要： A base station apparatus controls inter-terminal communication. A frame in which a first period in which the base station apparatus may broadcast a signal, a second period in which the terminal apparatus may broadcast the signal, and a third period in which one-to-one transmission of the signal between the base station apparatus and the terminal apparatus may be performed are time-division multiplexed is defined. A processing unit generates information about a configuration of the frame. A modem unit and an RF unit broadcast the signal in which the generated information is included in the first period. The RF unit, the modem unit, and the processing unit receive the signal broadcasted from the terminal apparatus in the second period. The RF unit, the modem unit, and the processing unit perform one-to-one communication with the terminal apparatus in the third period.

摘要： An RF unit receives periodically signals broadcast by other terminal apparatuses. When the quality of the signal received periodically is more deteriorated than a second threshold value even though the intensity of the signal received periodically is larger than a first threshold value, an identifying unit detects a malfunction in another terminal apparatus from which the signal received periodically by the receiver has been broadcast. A processing unit, a modem unit, the RF unit and an antenna each broadcasts a signal containing the detection result that the malfunction has been detected and information on a detected location.

摘要： A wireless unit performs a frequency conversion process, a quadrature modulation process, and a quadrature detection process. A modem performs a modulation/demodulation process. A processing unit performs digital signal processing on a signal from the modem and on a signal to the modem. An image capturing unit acquires an external image and outputs the acquired image to a coding unit. The coding unit generates image data by performing a compression encoding process on the image received from the image capturing unit and outputs the image data to a control unit. The control unit controls the overall movement of a vehicle camera apparatus.

摘要： A data processing unit selects either one of a base station mode and a terminal mode so as to perform communications using packet signals. The base station mode is a mode in which a packet signal, containing data indicating that an initial source and a final destination are not its own radio apparatus, is to be communicated; the terminal mode is a mode in which a packet signal, containing data indicating that the initial source or the final destination is its own radio apparatus, is to be communicated. A control unit starts the radio apparatus by setting the data processing unit in the terminal mode. When a packet signal, which has been transmitted from another radio apparatus and which contains broadcast information, has not been received before a certain period of time elapses after the start, the control unit switches the mode of the data processing unit to the base station mode.
