Abstract
A master device transmits a beacon signal including information related to a proximity wireless communication area in a predetermined cycle by using a transmission power which allows the beacon signal to reach beyond the proximity wireless communication area. When a slave device receives the beacon signal from the master device, the slave device estimates a distance to the master device in accordance with the information of the beacon signal. When a wireless communication terminal is located within the proximity wireless communication area, the slave device is connected to the master device by using a proximity wireless communication.
