摘要： A BLUETOOTH device is provided wherein the output RF transmission power level during pairing is purposefully reduced from otherwise conventional or normal communication levels to a low power level, greatly reducing the range of possible interception. Security can be improved even more by further reducing the transmit power even below that defined for a class 2 radio to an extremely low power level. After the link keys have been passed and/or other pairing processes, the BLUETOOTH devices may safely return to normal power levels to continue communications. Thus, a BLUETOOTH device is forced to radiate in low power when pairing is performed. The user(s) may be directed to co-locate the pairing BLUETOOTH devices in any appropriate manner, e.g., through a display prompt on the BLUETOOTH device. In an alternative embodiment, a BLUETOOTH device may be required to transmit data keys (e.g., a link key) and/or other pairing operations over a temporary wired connection (or temporary line-of-sight or near line-of-sight connection such as infrared) to another BLUETOOTH device.
