Abstract: The present invention relates to a method and an apparatus for determining a location of a device using multiple antenna switching. A method for determining a location of a device using multiple antenna switching according to one embodiment of the present invention may comprise: a first determination step of determining whether a device enters a target proximity zone or a target zone on the basis of a received signal strength indicator (RSSI) value received through a second antenna having a first coverage; a step of connecting a third antenna through antenna switching if it is determined that the device has entered the target proximity zone or the target zone in the first determining step; a second determination step of determining whether the device enters the target zone on the basis of a RSSI value received through the third antenna having a second coverage; and a step of confirming that the device has entered the target zone if it is determined that the device has entered the target zone in the second determination step.

Abstract: According to an embodiment, provided is a Bluetooth device comprising a master module and at least one slave module, wherein: the master module operates in an active mode when a mobile communication device is located within a pre-set range and switches to a power saving mode when the mobile communication device deviates from the pre-set range; in the active mode, the master module performs data communication by being connected to the mobile communication device located within the pre-set range and operates the Bluetooth device by periodically exchanging a packet with the slave module; and in the power saving mode, the master module operates in at least one of a first mode in which a packet exchange cycle with the slave module is adjusted from a first interval to a second interval, and a second mode in which a connection between the master module and the slave module is released.
