Abstract
A radio unit transmits a packet signal. An acquiring unit acquires information about a traveling status of a vehicle. When the acquired information indicates a stop of the vehicle, an instructing unit allows the radio unit to stop transmitting the packet signal. A position detecting unit detects, based on positional information of the vehicle, whether the vehicle is present in a predetermined area. If the position detecting unit detects presence, the instructing unit allows the radio unit to continue transmitting the packet signal even when the information acquired by the acquiring unit indicates the stop of the vehicle.
Claims6
A radio apparatus, comprising:
- a transmitting unit configured to transmit a packet signal;
- an acquiring unit configured to acquire information about a traveling status of a vehicle;
- and
- an instructing unit configured to allow the transmitting unit to decrease transmission frequency of the packet signal when the information acquired by the acquiring unit indicates a stop of the vehicle.
A radio apparatus, comprising:
- a transmitting unit configured to transmit a packet signal;
- a receiving unit configured to receive the packet signal from another radio apparatus;
- and
- an instructing unit configured to allow the transmitting unit to decrease transmission frequency of the packet signal when the receiving unit receives a predetermined number or larger of packet signals of which reception strength is larger than a threshold in a unit period.
