Basically, the Bluetooth-based unidirectional wireless signal is transmitted in the low power of the BLE mode. However, the Bluetooth-based unidirectional wireless signal transmitted in the signal strength of the BLE mode is difficult to reach the specified near point outside the vehicle. When operating through the vehicle power source, the operation module 250 controls the signal strength of the Bluetooth-based unidirectional wireless signal to be higher than a signal strength of the BLE mode (or to a maximum output in a usable range) It is preferable that the Bluetooth-based unidirectional radio signal is controlled so as to reach a specified short distance outside the vehicle regardless of various obstacles caused by materials such as various electronic apparatuses, a car body, and a window in the vehicle by amplifying and broadcasting (or broadcasting) .
