The present invention suggests to determine a spatial relationship between a mobile Bluetooth device and number of Bluetooth terminals to allow, through evaluation of the determined spatial relationship (like distance), for an automatic reconnection of the mobile Bluetooth device to one of the number of Bluetooth terminals. This allows reconnection without manual interaction by the user. Reconnection does not involve re-pairing. A wireless communication system comprising a mobile Bluetooth device (100), a first Bluetooth terminal (210) and a second Bluetooth terminal (220), the mobile Bluetooth device (100) comprising a memory (10) and a controller (40) adapted to engage in a first pairing process with the first Bluetooth terminal (210) as a result of which identical first link keys are stored in the mobile Bluetooth device (100) and in the first Bluetooth terminal (210), the controller (40) further being adapted to engage in a second pairing process with the second Bluetooth terminal (220) as a result of which identical second link keys are stored in the mobile Bluetooth device (100) and in the second Bluetooth terminal (220), characterised in that: - the controller (40) further is adapted to store in the memory (10) a first location (211), a first vicinity (212) and/or a first transmit power indication of the first Bluetooth terminal (210) when performing the first pairing process as well as to store in the memory (10) a second location (221), a second vicinity (222) and/or a second transmit power indication of the second Bluetooth terminal (220) when performing the second pairing process; - the mobile Bluetooth device (100) further comprises a comparator (20) adapted to determine a spatial relationship between the mobile Bluetooth device (100), the first Bluetooth terminal (210) and the second Bluetooth terminal (220) in dependence on at least one of the stored first location (211), the stored second location (221), the stored first vicinity (212), the stored second vicinity (222), the stored first transmit power indication and the stored second transmit power indication; - the mobile Bluetooth device (100) further comprises a selector (30) adapted to select from the first (210) and second (220) Bluetooth terminals a designated Bluetooth terminal by evaluating the determined spatial relationship; and - the controller (40) further is adapted to initiate a reconnection between the mobile Bluetooth device (100) and the designated Bluetooth terminal using the respective first or second link key stored during the respective first or second pairing process with the designated Bluetooth terminal.
