摘要：
A method to be executed by a user terminal for searching for locations of one or more wireless devices that are located within an area in which the one or more wireless devices can wirelessly communicate with the user terminal, wherein each of the one or more wireless devices periodically transmits a beacon signal. The method includes detecting a number of the one or more wireless devices that are located within the area based on the beacon signals; determining a transmission period for transmitting the beacon signals depending on the number of the one or more wireless devices; and instructing the one or more wireless devices that are located within the area to transmit the beacon signals in accordance with the determined transmission period.
