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. 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.
