Abstract
A short-range wireless communication system mounted on a vehicle includes a master device and slave devices. Each of the master device and slave devices is a short-range wireless communication device that communicates with a mobile terminal located in a communication range to perform a wireless communication. The master device includes a mobile terminal detection unit detecting the mobile terminal located in a communication range of the master device and an activation control unit performing an activation control to activate the slave devices in response to a detection of the mobile terminal by the mobile terminal detection unit. Each slave device is maintained in a deactivated state until activation control is performed by the activation control unit of the master device. Each slave device is activated when the activation control is performed by the activation control unit of the master device.
