There have been several versions of Bluetooth, with the most recent released definition being Bluetooth 4.0. The released versions differ greatly in bandwidth and the provided security. Since most of the available devices are still implemented according to Bluetooth 2.1 and earlier, this chapter will focus on their analysis. Like Wi-Fi, Bluetooth operates in the unlicensed 2.4 GHz ISM frequency band. Therefore it is primarily vulnerable to all physical layer Denial of Service (DoS) attacks like channel jamming. As BT implements channel-hopping at a very high rate, changing frequencies about 3200 times per second, it shows some resistance against these DoS attacks.
