Abstract
A wireless device includes a transmitter adapted with Bluetooth® low energy (BLE) capability and logic at least one of coupled to or integrated within the transmitter. The logic randomly generates a frequency offset based on bits within a frame synch packet to be transmitted during a keyless access attempt of an enclosure having a receiver. The logic causes the bits of the frame synch packet to be encrypted with an encryption key. The logic causes a frequency of the frame synch packet to modified by the frequency offset before the transmitter transmits the frame synch packet to the receiver.
